Just months after the Heartbleed bug made waves across the internet, a new security flaw has emerged which threatens to compromise everything from major servers to connected cameras. It is known as the Bash or Shellshock bug, a quarter-century old vulnerability that could put everything from major internet companies and small-scale web hosts to wi-fi connected devices at risk.
This flaw allows malicious code execution within the bash shell – commonly accessed through Command Prompt on PC or Mac’s Terminal application – to take over an operating system and access confidential information. According to the open-source software company Red Hat, bash shells are run in the background of many programs, and the bug is triggered when extra code is added within the lines of Bash code.
Because the bug interacts with a large percentage of software currently in use, and does in ways that are unexpected, Robert Graham – an internet security expert – claims that the Bash bug is bigger than Heartbleed. As he explained it:
We’ll never be able to catalogue all the software out there that is vulnerable to the Bash bug. While the known systems (like your Web server) are patched, unknown systems remain unpatched. We see that with the Heartbleed bug: six months later, hundreds of thousands of systems remain vulnerable.
According to a report filed by Ars Technica, the vulnerability could affect Unix and Linux devices, as well as hardware running Max OS X – particularly Mac OS X Mavericks (version 10.9.4). Graham warned that the Bash bug was also particularly dangerous for connected devices because their software is built using Bash scripts, which are less likely to be patched and more likely to expose the vulnerability to the outside world.
And since the bug has existed for some two and a half decades, a great number of older devices will be vulnerable and need to be patched because of it. By contrast, The Heartbleed bug was introduced into OpenSSL more than two years ago, allowing random bits of memory to be retrieved from impacted servers. And according to security researcher Bruce Schneier, roughly half a million websites could be vulnerable.
For the time being, the administrative solution is to apply patches to your operating system. Tod Beardsley, an engineering manager at security firm Rapid7, claims that even though the vulnerability’s complexity is low, the level of danger it poses is severe. In addition, the wide range of devices affected by the bug make it essential that system administrators apply patches immediately.
As Beardsley explained during an interview with CNET:
This vulnerability is potentially a very big deal. It’s rated a 10 for severity, meaning it has maximum impact, and ‘low’ for complexity of exploitation — meaning it’s pretty easy for attackers to use it… The affected software, Bash, is widely used so attackers can use this vulnerability to remotely execute a huge variety of devices and Web servers. Using this vulnerability, attackers can potentially take over the operating system, access confidential information, make changes etc. Anybody with systems using bash needs to deploy the patch immediately.
Attackers can potentially take over the operating system, access confidential information, and make changes. After conducting a scan of the internet to test for the vulnerability, Graham reported that the bug “can easily worm past firewalls and infect lots of systems” which he says would be “‘game over’ for large networks”. Similar to Beardsley, Graham said the problem needed immediate attention.
In the meantime, Graham advised people to do the following:
Scan your network for things like Telnet, FTP, and old versions of Apache (masscan is extremely useful for this). Anything that responds is probably an old device needing a Bash patch. And, since most of them can’t be patched, you are likely screwed.
How lovely! But then again, these sorts of exploitable vulnerabilities are likely to continue to pop up until we rethink how the internet is run. As the Heartbleed bug demonstrated, the problem at the heart (no pun!) of it all is that vast swaths of the internet run on open-source software that is created by only a handful of people who are paid very little (and sometimes, not at all) for performing this lucrative job.
In addition, there is a terrible lack of oversight and protection when it comes to the internet’s infrastructure. Rather than problems being addressed in an open-source manner after they emerge, there needs to be a responsible body of committed and qualified individuals who have the ability to predict problems in advance, propose possible solutions, and come up with a set of minimum standards and regulations.
Ensuring that it is international body would also be advisable. For as the Snowden leaks demonstrated, so much of the internet is controlled the United States. And as always, people need to maintain a degree of vigilance, and seek out information – which is being updated on a regular basis – on how they might address any possible vulnerabilities in their own software.
I can remember reading not long ago that the growing amount of cyber-attacks would soon cause people to suffer from “alert fatigue”. Well, those words are ringing in my ears, as it seems that a growing awareness of our internet’s flaws is likely to lead to “bug fatique” as well. Hopefully, it will also urge people to action and lead to some significant reforms in how the internet is structured and administered.
Spacesuits have come a long way from their humble origins in the 1960s. But despite decades worth of innovation, the basic design remains the same – large, bulky, and limiting to the wearer’s range of movement. Hence why a number of researchers and scientists are looking to create suits that are snugger, more flexible, and more ergonomic. One such group hails from MIT, with a skin-tight design that’s sure to revolutionize the concept of spacesuits.
The team is led by Dava Newman, a professor of aeronautics and astronautics and engineering systems at MIT who previewed her Biosuit – playfully described by some as a “spidersuit” – at the TEDWomen event, held in San Fransisco in December of 2013. Referred to as a “second skin” suit, the design incorporates flexible, lightweight material that is lined with “tiny, muscle-like coils.”
Speaking of the challenges of spacesuit design, and her team’s new concept for one, Dava Newman had the following to say in an interview with MIT news:
With conventional spacesuits, you’re essentially in a balloon of gas that’s providing you with the necessary one-third of an atmosphere [of pressure,] to keep you alive in the vacuum of space. We want to achieve that same pressurization, but through mechanical counterpressure — applying the pressure directly to the skin, thus avoiding the gas pressure altogether. We combine passive elastics with active materials.
Granted, Newman’s design is the first form-fitting spacesuit concept to see the light of day. Back in the 1960’s, NASA began experimenting with a suit that was modeled on human skin, the result of which was the Space Activity Suit (SAS). Instead of an air-filled envelope, the SAS used a skin-tight rubber leotard that clung to astronaut like spandex, pressing in to protect the wearer from the vacuum of space by means of counter pressure.
For breathing, the suit had an inflatable bladder on the chest and the astronaut wore a simple helmet with an airtight ring seal to keep in pressure. This setup made for a much lighter, more flexible suit that was mechanically far simpler because the breathing system and a porous skin that removed the need for complex cooling systems. The snag with the SAS was that materials in the days of Apollo were much too primitive to make the design practical.
Little progress was made until Dava Newman and her team from MIT combined modern fabrics, computer modelling, and engineering techniques to produce the Biosuit. Though a far more practical counter-pressure suit than its predecessor, it was still plagued by one major drawback – the skintight apparatus was very difficult to put on. Solutions were proposed, such as a machine that would weave a new suit about the wearer when needed, but these were deemed impractical.
The new approach incorporates coils formed out of tightly packed, small-diameter springs made of a shape-memory alloy (SMA) into the suit fabric. Memory alloys are metals that can be bent or deformed, but when heated, return to their original shape. In this case, the nickel-titanium coils are formed into a tourniquet-like cuff that incorporates a length of heating wire. When a current is applied, the coil cinches up to provide the proper counter pressure needed for the Biosuit to work.
Bradley Holschuh, a post-doctorate in Newman’s lab, originally came up with the idea of a coil design. In the past, the big hurdle to second-skin spacesuits was how to get astronauts to squeeze in and out of the pressured, skintight suit. Holschuh’s breakthrough was to deploy shape-memory alloy as a technological end-around. To train the alloy, Holschuh wound raw SMA fiber into extremely tight coils and heated them to 450º C (842º F) to fashion an original or “trained” shape.
When the coil cooled to room temperature, it could be stretched out, but when heated to 60º C (140º F), it shrank back into its original shape in what the MIT team compared to a self-closing buckle. As spokespersons from MIT explained:
The researchers rigged an array of coils to an elastic cuff, attaching each coil to a small thread linked to the cuff. They then attached leads to the coils’ opposite ends and applied a voltage, generating heat. Between 60 and 160 C, the coils contracted, pulling the attached threads, and tightening the cuff.
In order to maintain it without continually heating the coils, however, the team needs to come up with some sort of a catch that will lock the coils in place rather than relying on a continuous supply of electricity and needlessly heating up the suit – yet it will still have to be easy to unfasten. Once Newman and her team find a solution to this problem, their suit could find other applications here on Earth.
As Holschuh explained, the applications for this technology go beyond the spacesuit, with applications ranging from the militarized to the medical. But for the moment, the intended purpose is keeping astronauts safe and comfortable:
You could [also] use this as a tourniquet system if someone is bleeding out on the battlefield. If your suit happens to have sensors, it could tourniquet you in the event of injury without you even having to think about it… An integrated suit is exciting to think about to enhance human performance. We’re trying to keep our astronauts alive, safe, and mobile, but these designs are not just for use in space.
Considering the ambitious plans NASA and other government and private space agencies have for the near-future – exploring Mars, mining asteroids, building a settlement on the Moon, etc. – a next-generation spacesuit would certainly come in handy. With new launch systems and space capsules being introduced for just this purpose, it only makes sense that the most basic pieces of equipment get a refit as well.
And be sure to check out this video of Dava Newman showing her Biosuit at the TEDWomen conference last year:
Robotic exoskeletons have come a long way, and are even breaking the mold. When one utters the term, it tends to conjure up images of a heavy suit with a metal frame that bestows the wearer super-human strength – as exemplified by Daewoo’s robot worker suits. And whereas those are certainly making an impact, there is a burgeoning market for flexible exoskeletons that would assist with everyday living.
Researchers at Harvard’s Wyss Institute for Biologically Inspired Engineering have developed just such a device, a flexible fabric exoskeleton that earned them a $2.9 million grant by DARPA to continue developing the technology. Unlike the traditional exoskeleton concept, Harvard’s so-called “Soft Exosuit” is not designed to give the wearer vastly increase lifting capacity.
Instead, the Soft Exosuit works with the musculature to reduce injuries, improve stamina, and enhance balance even for those with weakened muscles. In some ways, this approach to wearable robotics is the opposite of past exoskeletons. Rather than the human working within the abilities and constraints of the exoskeleton, the exoskeleton works with the natural movements of the human wearer.
The big challenge of this concept is designing a wearable machine that doesn’t get in the way. In order to address this, the Wyss Institute researchers went beyond the usual network of fabric straps that hold the suit in place around the user’s limbs. In addition, they carefully studied the way people walk and determined which muscles would benefit from the added forces offered by the Exosuit.
With a better understanding of the biomechanics involved, the team decided to go with a network of cables to transmit forces to the joints. Batteries and motors are mounted at the waist to avoid having any rigid components interfering with natural joint movement. This allows the wearer the freedom to move without having to manually control how the forces are applied.
Basically, the wearer does not have to push on a joystick, pull against restraints, or stick to a certain pace when walking with the Exosuit. The machine is supposed to work with the wearer, not the other way around. The designers integrated a network of strain sensors throughout the straps that transmit data back to the on-board microcomputer to interpret and apply supportive force with the cables.
DARPA is funding this project as part of the Warrior Web program, which seeks to reduce musculoskeletal injuries for military personnel. However, Harvard expects this technology to be useful in civilian applications as well. Anyone who needs to walk for long periods of time at work could benefit from the Soft Exosuit, which is less expensive and more comfortable that conventional exosuits; and with a little rescaling, could even be worn under clothing.
But the greatest impact of the Soft Exosuit is likely to be for those who suffer from a physical impairment and/or injuries. Someone that has trouble standing or walking could possibly attain normal mobility with the aid of this wearable robot. And people working their way through physiotherapy would find it very useful in assisting them with restoring their muscles and joints to their usual strength.
The team plans to collaborate with clinical partners to create a version of the exosuit for just this purpose. What the Wyss Institute has demonstrated so far has just been the general proof-of-concept for the Soft Exosuit. In time, and with further refinements, we could see all sorts of versions becoming available – from the militarized to the medical, from mobility assistance for seniors, to even astronauts looking to prevent atrophy.
And as always, technology that is initially designed to assist and address mobility issues is likely to give way to enhancement and augmentation. It’s therefore not hard to imagine a future where soft robotic exosuits are produced for every possible use, including recreation and transhumanism. Hell, it may even be foreseeable that an endoskeleton will be possible in the not-too-distant future, something implantable that can do the same job but be permanent…
Cool and scary! And be sure to check out this video from the Wyss Institute being tested:
For decades, the dream of quantum computing – a system that makes direct use of quantum-mechanical phenomena, such as superposition and entanglement, to perform operations on data- has been just that. Much the same is true of principles that expand on this concept, such as quantum encryption and a quantum internet. But thanks to ongoing studies and experiments by researchers and scientists, that dream may be closer to fruition than ever.
This time the progress comes from a research team out of Professor Nicolas Gisin lab’s in the physics department at the University of Geneva. The team achieved the teleportation of the quantum state of a photon – this time, the photon’s polarization – to a crystal-encased photon more than 25 kilometers (15.5 miles) away. The distance breaks the previous record of 6 kilometers (3.7 miles) set 10 years ago by the same team using the same method.
This is the latest in a series of experiments the group, led by physicist Félix Bussières, have conducted over the last decade in an effort to better understand quantum data transfer. In this particular experiment, the researchers stored one photon in a crystal, essentially creating a solid-state memory bank. They sent another photon of a different wavelength 25 km away through optical fiber, whereupon they had it interact with a third photon.
Because the first two photons were entangled – a quantum property whereby particles can speak to each other across an infinite distance – the interaction sent the data to the photo stored in the memory bank, where the team was able to retrieve it. Or as the team explained, using pool balls as an anology:
It is a bit like a game of billiards, with a third photon hitting the first which obliterates both of them. Scientists measure this collision. But the information contained in the third photon is not destroyed – on the contrary it finds its way to the crystal which also contains the second entangled photon.
This is all in keeping with the concept of quantum teleportation – the moving of quantum data from one location to another without having to travel the distance between them. That means that the speed at which data moves isn’t necessarily limited by the constraints of space and time. In that sense, it’s easier to think of this kind of teleporting not as a “beam me up” scenario, but as a kind of instantaneous awareness between two points.
While this may not sound as exciting as Ursula K. Le Guin’s Ansible communicator, the Alcubierre warp drive, or the “Star Trek”-style transporter, it opens up startling possibilities. For instance, in addition to bringing us closer to hard drives that can store quantum bits (aka. qubits), this is a major step in the direction of a quantum internet and encryption- where information is sent around the world instantaneously and is extremely secure.
This also opens doors for space exploration, where astronauts in space, rovers on Mars, and satellites in deep space will be able to communicate instantly with facilities here on Earth. For non-quantum physicists, the novel aspect of this experiment is that the team achieved teleportation of data across the kind of optic fiber that forms the basis of modern-day telecommunications, which means no major overhaul will be needed to make quantum internet a reality.
As physicists continue to push the boundaries of our understanding about the quantum world, we’re getting closer to translating these kinds of advancements in market applications. Already, quantum computing and quantum encryption are making inroads into the sectors of banking security, medical research and other areas in need of huge computing muscle and super-fast information transfer.
With the rise of a potential quantum Internet on the horizon, we could see the next jump in communication happen over the next couple of decades. So while we’re a long way off from trying to pry quantum teleportation and entanglement from the grip of the theoretical realm, scientists are making headway, if only a handful of kilometers at a time. But every bit helps, seeing as how routing stations and satellites can connect these distances into a worldwide network.
In fact, research conducted by other labs have not only confirmed that quantum teleportation can reach up to 143 km (89 miles) in distance, but that greater and greater properties can be beamed. This distance is especially crucial since it happens to be close to what lies between the Earth and a satellite in Low-Earth Orbit (LEO). In short, we humans could construct a quantum internet using optic cables or satellites, mirroring the state of telecommunications today.
And when that happens, get ready for an explosion in learning, processing and information, the likes of which has not been seen since the creation of the printing press or the first internet revolution!
Organ transplants are one of the greatest medical advances of the 20th century. Where patients once faced disability or even death, they’ve been given a new lease on life in the form of donated organs. The problem is that the supply of suitable donor organs has always been in a state of severe shortage. Not only is it entirely dependent on accident victims who have signed their organ donor card, there is also the issue of genetic suitability.
For decades, scientists have worked on producing lab-grown organs to pick up the slack left by the donor system. The research has yielded some positive results in the form of simple organs, such as the artificial esophagus and “mini-kidneys.” Nevertheless, the creation of whole, complex, functional organs that can be swapped for damaged or destroyed ones has remained out of reach. That is, until now.
Scientists at the University of Edinburgh have grown a fully-functional organ inside a mouse, a breakthrough that opens up the possibility of one day manufacturing compatible organs for transplant without the need for donors. Using mouse embryo cells, scientists at the MRC Centre for Regenerative Medicine created an artificial thymus gland with the same structure and function as an adult organ.
The University of Edinburgh team produced the artificial thymus gland using a technique that the scientists call “reprogramming.” It involves fibroblast cells, which form connective tissue in animals, being removed from a mouse embryo and then treated with a protein called FOXN1 to change them into thymic epithelial cells (TEC). These were then mixed with other thymus cells and transplanted into living mice by grafting them to the animal’s kidneys.
Then, over a period of four weeks, the cells grew into a complete, functioning thymus gland that can produce T cells – an important part of the immune system. According to the scientists, this development goes beyond previous efforts because the thymus serves such a key part in protecting the body against infection and in eliminating cancer cells. This is clearly the first step on the road towards complete organ development.
The team is currently working on refining the reprogramming technique in the hope of developing a practical medical procedure, such as creating bespoke thymus glands made to match a patient’s own T cells. They see the development of a lab-grown thymus as a way of treating cancer patients whose immune system has been compromised by radiation or chemotherapy, and children born with malfunctioning thymuses.
According to Rob Buckle, Head of Regenerative Medicine at the MRC, the potential is tremendous and far-reaching:
Growing ‘replacement parts’ for damaged tissue could remove the need to transplant whole organs from one person to another, which has many drawbacks – not least a critical lack of donors. This research is an exciting early step towards that goal, and a convincing demonstration of the potential power of direct reprogramming technology, by which one cell type is converted to another. However, much more work will be needed before this process can be reproduced in the lab environment, and in a safe and tightly controlled way suitable for use in humans.
Combined with “bioprinting” – where stem cells are printed into organs using a 3-D printer – organs transplants could very well evolve to the point where made-to-order replacements are fashioned from patient’s own genetic material. This would not only ensure that there is never any shortages or waiting lists, but that there would be no chance of incompatibility or donor rejection.
Another step on the road to clinical immortality! And be sure to check out this video of the artificial thymus gland being grown, courtesy of the Medical Research Council:
There have been lots of high-speed bio-inspired robots in recent years, as exemplified by Boston Dynamics WildCat. But MIT’s Cheetah robot, which made its big debut earlier this month, is in a class by itself. In addition to being able to run at impressive speeds, bound, and jump over obstacles, this particular biomimetic robot is also being battery-and-motor driven rather than by a gasoline engine and hydraulics, and can function untethered (i.e. not connected to a power source).
While gasoline-powered robots are still very much bio-inspired, they are dependent on sheer power to try and match the force and speed of their flesh-and-blood counterparts. They’re also pretty noisy, as the demonstration of the WildCat certainly showed (video below). MIT’s Cheetah takes the alternate route of applying less power but doing so more efficiently, more closely mimicking the musculoskeletal system of a living creature.
This is not only a reversal on contemporary robotics, but a break from history. Historically, to make a robot run faster, engineers made the legs move faster. The alternative is to keep the same kind of frequency, but to push down harder at the ground with each step. As MIT’s Sangbae Kim explained:
Our robot can be silent and as efficient as animals. The only things you hear are the feet hitting the ground… Many sprinters, like Usain Bolt, don’t cycle their legs really fast. They actually increase their stride length by pushing downward harder and increasing their ground force, so they can fly more while keeping the same frequency.
MIT’s Cheetah uses much the same approach as a sprinter, combining custom-designed high-torque-density electric motors made at MIT with amplifiers that control the motors (also a custom MIT job). These two technologies, combined with a bio-inspired leg, allow the Cheetah to apply exactly the right amount of force to successfully bound across the ground and navigate obstacles without falling over.
When it wants to jump over an obstacle, it simply pushes down harder; and as you can see from the video below, the results speak for themselves. For now, the Cheetah can run untethered at around 16 km/h (10 mph) across grass, and hurdle over obstacles up to 33 centimeters high. The Cheetah currently bounds – a fairly simple gait where the front and rear legs move almost in unison – but galloping, where all four legs move asymmetrically, is the ultimate goal.
With a new gait, and a little byte surgery to the control algorithms, MIT hopes that the current Cheetah can hit speeds of up to 48 km/h (30 mph), which would make it the fastest untethered quadruped robot in the world. While this is still a good deal slower than the real thing – real cheetah’s can run up to 60 km/h (37 mph) – it will certainly constitute another big step for biomimetics and robotics.
Be sure to check out the video of the Cheetah’s test, and see how it differs from the Boston Dynamics/DARPA’s WildCat’s tests from October of last year:
There are drones for aerial reconnaissance, drones for domestic surveillance, and drones for raining hell, death and destruction down on enemy combatants. But drones for making personal deliveries? That’s a relatively new one. But it is a not-too-surprising part of an age where unmanned aerial vehicles are becoming more frequent and used for just about every commercial applications imaginable.
After working on secret for quite some time, Google’s secretive projects lab (Google X) recently unveiled its drone-based delivery system called Project Wing. On the surface, the project doesn’t look much different from Amazon’s Prime Air aut0nomous quadcopter delivery service. However, on closer inspection, Project Wing appears to be much more ambitious, and with more far-reaching goals.
The original concept behind Project Wing — which has been in development for more than two years — was to deliver defibrillators to heart attack sufferers within two minutes. But after running into issues trying to integrate its tech with the US’s existing 911 and emergency services systems, the focus shifted to the much more general problem of same-day deliveries, disaster relief, and delivering to places that same- and next-day couriers might not reach.
For their first test flights, the Google team traveled to Australia to conduct deliveries of dog food to a farmer in Queensland. All 31 of Project Wing’s full-scale test flights have been conducted in Australia, which has a more permissive “remotely piloted aircraft” (i.e. domestic drones) policy than the US. There’s no word on when Project Wing might be commercialized, but it is estimated that it will be at least a couple of years.
While most work in small-scale autonomous drones and remotely piloted aircraft generally revolves around quadcopters, Google X instead opted for a tail-sitter design. Basically, the Project Wing aircraft takes off and lands on its tail, but cruises horizontally like a normal plane. This method of vertical-takeoff-and-landing (VTOL) was trialed in some early aircraft designs, but thrust vectoring was ultimately deemed more practical for manned flight.
The Project Wing aircraft has four electric motors, a wingspan of around 1.5m (five feet), and weighs just under 8.6 kg (19 pounds). Fully loaded, the drones apparently weigh about 10 kg (22 pounds) and are outfitted with the usual set of radios and sensors to allow for autonomous flight. But there’s also a camera, which can be used by a remote pilot to ensure that the aircraft drops its package in a sensible location.
As you can see from the video below, the packages are dropped from altitude, using a winch and fishing line. Early in the project, Google found that people wanted to collect packages directly from the drone, which was impractical when the engines were running. The air-drop solution is much more graceful, and also allows the drone to stay away from a large variety of low-altitude obstacles (humans, dogs, cars, telephone lines, trees…)
This is another major different with Amazon Prime Air’s drones, which carry their package on the drone’s undercarriage and land in order to make the delivery. And while their octocopters do have slightly better range – 1.6 km (1 mile), compared to Project Wing’s 800 meters (half a mile) – Google is confident its delivery system is safer. And they may be right, since its not quite clear how small children and animals will react to a landing object with spinning rotors!
For the moment, Google has no specific goal in mind, but the intent appears to be on the development for a full-scale same-day delivery service that can transport anything that meets the weight requirements. As Astro Teller, director of Google X labs, said in an interview with The Atlantic:
Throughout history there have been a series of innovations that have each taken a huge chunk out of the friction of moving things around. FedEx overnight delivery has absolutely changed the world again. We’re starting to see same-day service actually change the world. Why would we think that the next 10x — being able to get something in just a minute or two — wouldn’t change the world?
Nevertheless, both projects are still years away from realization, as both have to content with FAA regulations and all the red tape that come with it. Still, it would not be farfetched to assume that by the 2020’s, we could be living in a world where drones are a regular feature, performing everything from traffic monitoring and aerial reconnaissance to package delivery.
And be sure to check out these videos from CNET and Amazon, showing both Project Wing and Prime Air in action:
The race to produce a new era or reusable and cost-effective spacecraft has been turning out some rather creative and interesting designs. DARPA’s XS-1 Spaceplane is certainly no exception. Developed by Northrop Grumman, in partnership with Scaled Composites and Virgin Galactic, this vehicle is a major step towards producing launch systems that will dramatically reduce the costs of getting into orbit.
Key to DARPA’s vision is to develop a space-delivery system for the US military that will restore the ability of the US to deploy military satellites ingeniously. In a rather ambitious twist, they want a vehicle that can be launched 10 times over a 10-day period, fly in a suborbital trajectory at speeds in excess of Mach 10, release a satellite launch vehicle while in flight, and reduce the cost of putting a payload into orbit to US$5 million (a tenth of the current cost).
Under DARPA contracts, Boeing, Masten Space Systems, and Northrop Grumman are working on their own versions of the spaceplane. The Northrop plan is to employ a reusable spaceplane booster that, when coupled with an expendable upper stage, can send a 1360 kgs (3,000 pounds) spacecraft into low Earth orbit. By comping reusable boosters with aircraft-like operations on landing, a more cost-effective and resilient spacecraft results.
In flight, the Northrop version of the XS-1 will take advantage of the company’s experience in unmanned aircraft to use a highly autonomous flight system and will release an expendable upper stage, which takes the final payload into orbit. While this is happening, the XS-1 will fly back to base and land on a standard runway like a conventional aircraft, refuel, and reload for the next deployment.
Northrop is working under a $3.9 million phase one contract with DARPA to produce a design and flight demonstration plan that will allow the XS-1 to not only act as a space launcher, but as a testbed for next-generation hypersonic aircraft. Meanwhile Scaled Composites, based in Mojave, will be in charge of fabrication and assembly while Virgin Galactic will handle commercial spaceplane operations and transition.
Doug Young, the vice president of missile defense and advanced missions at Northrop Grumman Aerospace Systems, had this to say about the collaboration:
Our team is uniquely qualified to meet DARPA’s XS-1 operational system goals, having built and transitioned many developmental systems to operational use, including our current work on the world’s only commercial spaceline, Virgin Galactic’s SpaceShipTwo. We plan to bundle proven technologies into our concept that we developed during related projects for DARPA, NASA and the U.S. Air Force Research Laboratory, giving the government maximum return on those investments.
Regardless of which contractor’s design bears fruit, the future of space exploration is clear. In addition to focusing on cutting costs and reusability, it will depend heavily upon public and private sector collaboration. As private space companies grab a larger share of the space tourism and shipping market, they will be called upon to help pick up the slack, and lend their expertise to more ambitious projects.
Examples abound, from putting satellites, supplies and astronauts into orbit, to landing settlers on Mars itself. And who knows? In the foreseeable future, NASA, Russia, China, the ESA and Japan may also be working hand-in-hand with transport and energy companies to make space-based solar power and a space elevator a reality!
This past summer, the FBI was compelled to release information about the operational facial recognition database they working on. As part of its Next Generation Identification (NGI) program, this database is part of the FBIs efforts to build a “bigger, faster and better” means of biometric identification. Earlier this month, the FBI announced that the system is now working at “full operational capability”, and many people are worried…
To break it down, the NGI database is made up of millions of stored mugshots and other photos, which are then used when analyzing footage taken by CCTV feeds or other cameras around the country. The full deployment of the program comes three months after James Comey, the bureau’s director, announced that the agency was “piloting the use of mug shots” alongside the bureau’s other databases, in order to catch wanted criminals.
Designed to replace the bureau’s aging fingerprint database, the NGI is different in that it is designed to be multimodal. This means that it will link multiple forms of biometric data to biographical information such as name, address, ID number, age and ethnicity. It’s currently focused on fingerprint and facial records, but it will also be capable of holding iris scans and palm prints, with the possibility of added voice recognition and gate analysis (i.e. how people walk).
As the FBI said in a statement on Monday, Sept. 15th, the NGI, combined with fingerprint database:
[W]ill provide the nation’s law enforcement community with an investigative tool that provides an image-searching capability of photographs associated with criminal identities.
Naturally, the worries that this database will be another step towards “Big Brother” monitoring. However, what is equally (if not more) worrisome is the fact that the details of the program are only a matter of public record thanks to a lawsuit filed by the Electronic Frontier Foundation. The lawsuit was issued in June of 2013, wherein the EFF compelled the FBI to produce records in accordance Freedom of Information Act to detail the program and its face-recognition components.
Citing the FBI documents, the EFF claims that the facial recognition technology is not very reliable and that the way the database returns results is fundamentally flawed, as well as pointing out that it will indiscriminately combine the details of both criminals and non-criminals. Based on their own interpretation, they claim it could fail 20 percent of the time, which could lead to innocent persons becoming the subject of police investigations.
Nevertheless, the bureau remains confident that the system will simplify and enhance law enforcement both locally and federally. As they said of the program when it was first announced back in 2011:
The NGI system has introduced enhanced automated fingerprint and latent search capabilities, mobile fingerprint identification, and electronic image storage, all while adding enhanced processing speed and automation for electronic exchange of fingerprints to more than 18,000 law enforcement agencies and other authorized criminal justice partners 24 hours a day, 365 days a year.
In 2012, the NGI database already contained 13.6 million images (of seven to eight million individuals) and by mid-2013, it had 16 million images. We now know it aims to have 52 million facial records in its system by next year, and those will include some regular citizens. This is another source of concern for the EFF and civil liberties advocates, which is the estimated 4.3 million images taken for non-criminal purposes.
Whenever someone applies for a job that requires a background check, they are required to submit fingerprint records. These records are then entered into federal databases. Right now, the FBI’s fingerprint database contains around 70 million criminal profiles, and 34 million non-criminal records. With the NGI database now up and running, photographs can be submitted by employers and other sources along with fingerprints, which puts non-criminals on file.
The database, while maintained by the FBI, can be searched by law enforcement at all levels. According to Jennifer Lynch, the EFF attorney behind the lawsuit:
Your image would be searched every time there is a criminal investigation. The problem with that is the face recognition is still not 100 percent accurate.” This means that the system is liable to make mismatches with data. If a camera catches a criminal’s face and that is compared to images in the database, there’s no guarantee that it will pop up an accurate result.
What’s more, when the database is searched it does not return a completely positive result; but instead provides the top hits, ranked by probability of match. So if your face just happens to be similar to a snapshot of a criminal caught in CCTV footage, you may become a suspect in that case. Combined with other forms of biometric readers and scanners, it is part of a general trend where privacy is shrinking and public spaces are increasingly permeated by digital surveillance.
This sort of data exchange and on-the-ground scanning will be made possible by – and is one of the explicit aims of – FirstNet, the nationwide broadband network for law enforcement and first responders, colloquially referred to by some as the “internet of cops”. Much like all things pertaining the expansion of the internet into the “internet of things”, this sort of growth has the capacity to affect privacy and become invasive as well as connective.
As always, fears of an “Orwellian” situation can be allayed by reminding people that the best defense is public access to the information – to know what is taking place and how it works. While there are doubts as to the efficacy of the NGI database and the potential for harm, the fact that we know about its inner workings and limitations could serve as a legal defense wherever a potentially innocent person is targeted by it.
And of course, as the issue of domestic surveillance grows, there are also countless efforts being put forth by “Little Brother” to protect privacy and resist identification. The internet revolution cuts both ways, and ensures that everyone registered in the torrential data stream has a degree of input. Fight the power! Peace out!
As a young man, there were few things cooler to me than tanks. Sure, I wanted to be a pilot at the time, with visions of fighter jets dancing in my head. But armored warfare and the cool and advanced designs of modern MBTs (Main Battle Tanks) were never far behind. And so I thought it was high time I did a post dedicated to the world of these behemoths and what the current crop have to offer.
British Mark V tank, ca. 1917
Originally invented in World War I as a means of infantry support, tanks quickly evolved over the ensuing decades to become a distinct and fearsome weapon of war. In 1917, they were deployed as a means of breaking the stalemate caused by trench warfare, and were little more than lumbering, thinly-skinned land fortresses. But by 1939/40, their use as fast, cohesive offensive weapons that could break through enemy lines and encircle entire armies was demonstrated.
Russian T-34/76 in World War II
Throughout the Second World War, tanks continued to evolve to sport heavier armor and guns with increased size, range, and muzzle velocity. By the end of the war, some truly interesting designs had been produced by all sides, ranging from the light to the super-heavy. But these were largely abandoned in favor of designs that could be mass produced and had a good balance of speed, durability, firepower and protection.
American M1 Abrams MBT
And by the 1970’s, the Cold War spurred on numerous developments that would culminate in the c0ncept of the MBT. These included the development of lighter, composite armor and advanced anti-armor systems. In addition, the MBT concept was intended to fill the heavy direct fire role of modern armies and replace the light, medium, heavy and super-heavy tanks that were common.
Since that time, every major world power has produced its own variant of the MBT. Here are all the top contenders, group in alphabetical order…
AMX Leclerc: Named in honor of General Philippe Leclerc de Hauteclocque, who led the French element of the drive towards Paris during World War II, the AMX Leclerc is The Main Battle Tank of France. Beginning production in 1991, the tank is now in service with the French Army, the army of the United Arab Emirates, and is also renowned for being the most expensive tank in history.
The tank’s main gun is the GIAT (Nexter) CN120-26 120mm smoothbore cannon, which is capable of firing the same NATO standard 120mm rounds as the German Leopard 2 and US M1 Abrams. Unlike other MBTs of its generation, the Leclerc comes with an autoloading system which reduces the crew to three, and has an ammo capacity of 40 rounds. It is also equipped with a 12.7 mm coaxial machine gun and a remote-controlled 7.62mm machine gun,
The hull and the turret are made of welded steel fitted with modular armor, which can be replaced easily for repair or upgraded over the years. Unlike other NATO tanks, the Leclerc does not use the standard Chobham composite armor and relies instead on a French variant that includes composite armor, titanium inserts on the sides of the turret, and Explosive Reactive Armor (ERA) blocks.
It’s eight-cylinder 1,000KW (1,500 hp) diesel engine can achieve a top speed of 72 km/h (45 mph) and it has an operational range of 550 km (342 mi) or 650 km (400 mi) with external fuel tanks.
Arjun: The MBT of India and produced by the Defence Research and Development Organization (DRDO), the Arjun is named after the main protagonist and world’s greatest archer from the Indian epic, The Mahabharata. Design of the tank began in 1974 as a way of providing the Indian Army with an indigenously-designed and built tank. But delays prevented it from being officially developed until 2004.
The Arjun sports a 120 mm main rifled gun with indigenously developed Armor-Piercing Fin-Stabilized Discarding-Sabot (APFSDS) ammunition, one 7.62 mm coaxial machine gun, and a 12.7 mm machine gun. The tanks is protected by the modular composite Kanchan armor that is composed of layers of composite alongside rolled homogenous steel, and a new honeycomb design of non-explosive and non-energetic reactive armor (NERA) is reportedly being tested as well.
Like most MBTs of its generation, the Arjun has a four-man crew, including the commander, gunner, loader and a driver. It is powered by a single MTU multi-fuel diesel engine rated at 1,400 hp, and can achieve a maximum speed of 70 km/h (43 mph) and a cross-country speed of 40 km/h (25 mph).
C1 Ariete: The MBT of the Italian Army, the Ariete was developed by a consortium formed by Iveco-Fiat and Oto Melara (aka CIO, Consorzio Iveco Oto Melara), with the chassis and engine produced by Iveco and the turret and fire-control system supplied by Oto Melara. Development began in 1988, with the first prototypes being delivered by 1995 and the tank entering into full service by 2002.
The Ariete’s main armament is a native 120 mm smoothbore cannon that uses the APFSDS-T, HEAT, and most NATO-standard rounds of the same caliber. The tank has a capacity of 42 rounds and secondary armaments consist of a 7.62 mm MG 42/59 coaxial machine gun and an additional 7.62 mm MG 42/59 configured as an anti-aircraft weapon that is fired from the hatch.
The vehicle carries the latest optical and digital-imaging and fire-control systems, which include a laser range-finder, thermal optics and a digital fire-control computer that can be networked. The Ariete’s armor is a steel and composite blend, similar to the British Challenger 2 and the American M1 Abrams. The tank is powered by a 25.8-litre turbo-charged Fiat-Iveco MTCA 12-cylinder diesel engine rated at 937 kilowatts (1,250 hp) that allows for a top cruising speed of 65 km/h.
Challenger 2: The MBT of the British Army, the Challenger 2 was designed and built by the British company Vickers Defence Systems (now known as BAE Systems Land and Armaments). Development of the tank began back in 1986 as an eventual replacement for the Challenger 1, which served as the mainstay of the British armor forces from the early 80s to the mid-90s.
The tanks main gun is the 120 millimeters L30A1 cannon which, unlike other NATO MBT’s, is rifled so that it can fire the high explosive squash head (HESH) rounds in addition to APFSDS armor-piercing rounds. The Challenger 2 is also armed with a 7.62 mm coaxial chain gun. a 7.62 mm roof-mounted machine gun, and can also mount a remote weapons system with a 7.62 mm machine gun, a 12.7mm heavy machine gun, or a 40mm automatic grenade launcher.
Challenger 2 is one of the most heavily armored and best protected tanks in the world, employing second-generation Chobham armor (aka. Dorchester) that is sloped in order to deflect the explosive energy of anti-tank weapons. Explosive Reactive Armor (ERA) kits are also fitted as necessary along with additional bar armor and the tank’s shape is also designed with stealth technology to reduce radar signature.
The tank’s advanced targeting systems include a laser range-finder, night vision, thermal vision, digital fire control, and the option of a Battlefield Information Control System. It’s drive system consists of a Perkins 26.6 liter CV12 diesel engine delivering 890 kW (1,200 hp). It is capable of reaching 60 km/h (37 mph) on open road for 450 km (280 mi), or 40 km/h (25 mph) cross-country for 250 km (156 mi).
K2 Black Panther: A fourth-generation MBT in service with the South Korean armed forces, the K2 began development in 1995 and officially entered service in 2014. Despite enjoying technical superiority over North Korea’s aging army of T-55 and T-59 tanks, the purpose of the K2 was to create an MBT using entirely indigenous technology which could also be sold on the foreign export.
In terms of armament, the K2 comes equipped with L55 120 mm 55 caliber smoothbore gun that – capable of firing standard APFSDS rounds, as well as the Korean Smart Top-Attack Munition (KSTAM) anti-tank missile – a 12.7 mm heavy machine gun and a 7.62 mm coaxial machine gun. It also comes equipped with an advanced Fire Control System (FCS) linked to a millimeter band radar system along with a traditional laser range-finder and crosswind sensor.
In terms of protection, the K2 employs a classified type of composite armor with ERA and NERA modular add-ons, in addition to soft-kill and hard-kill anti-missile defense systems. It also has a Radar Warning Receiver (RWR), radar jammer and Laser Warning Receivers (LWR) to alert the crew if the vehicle becomes “painted” and to deploy Visual and Infrared Screening Smoke (VIRSS) grenades.
The tanks drive system is a 4-cycle, 12-cylinder water-cooled diesel engine capable of generating 1,100 kW (1500 hp), with an operation range of 450 kilometers (280 mi). Its top speed on paved road is 70 km/h (43 mph), and 50 km/h (31 mph) cross-country.
Leopard 2: Developed by Krauss-Maffei in the early 1970s for the West German Army, the Leopard 2 entered service in 1979 to replace the older Leopard 1 models. In addition to being the MBT of a united Germany after 1989, the Leopard 2 is also one of the most widely-used tanks in the world, serving in a total of 16 armies that range from Germany and Austria, to Canada, Turkey, Singapore and Indonesia. Due to improved technology, the tank has also gone through many variations.
The primary gun on the Leopard 2 is the Rheinmetall L/44 120 mm smoothbore gun, which is capable of firing APFSDS warheads as well as the German DM12 multipurpose anti-tank projectile (MPAT) and the LAHAT anti-tank guided missile. It also has two 7.62mm machine guns, a coaxially-mounted one in the turret, and the other on an external anti-aircraft mount. The tank also has a stabilization system, a laser rangefinder, thermal imaging and a fire control computer.
For protection, the Leopard 2 uses spaced, multi-layered composite armor that incorporates Rolled Homogenous Armor (RHA), interior spall liners and the option of slat armor on the sides to protect from Rocket-Propelled Grenades (RPGs). The Leopard 2 is also equipped with a fire protection system that automatically dispenses halomethane foam in the event that the interior temperature rises above a certain point.
It is powered by a 1,103 kW (1,479 hp) V-12 liquid-cooled twin-turbo diesel engine with a fuel capacity of 1200 liters (317 gallons). It has a top speed of 72 km/h (45 mph) and an operational range of 550 km (340 mi).
M1 Abrams:The M1 is a third-generation tank and the MBT of the US Army US Marine Corps, Australian, Egyptian, Kuwaiti and Saudi Arabian armies. Development began in 1972 and culminated in 79, with the first tanks entering service in 1980 to replace the older M60 Patton tank. Since that time, it has gone through multiple upgrades and variants in order to take advantage of the latest in technology.
Though the original M1 was equipped with the M68A1 105 mm rifled tank gun, it was quickly upgraded to a 44 and then 55 caliber 120 mm smoothbore gun (variants on Rheinmetall’s L/44 and L/55 used by the Leopard 2). It is capable of firing the APFSDS and HEAT rounds, as well as the M1028 anti-personnel canister cartridge. It also comes with two 7.62mm machine guns – one coaxial and one turret-mounted – and a 12.7mm machine gun mounted by the commander’s hatch.
The tank also has a full-stabilization system for the main gun an comes equipped with a laser rangefinder, crosswind sensor, a pendulum static cant sensor, thermal imaging and a firing computer. The tank’s crew is protected by a halon firefighting system similar to the Leopard 2’s, and a rear ammo compartment with blowout panels that protect the crew from its own ammo exploding.
The tank is protected by composite armor that is composed of alloys of steel, ceramics, plastic composites, and Kevlar, similar to British Chobam armor. It may also be fitted with reactive armor over the track skirts if needed and slat armor over the rear of the tank and rear fuel cells to protect against RPGs. Beginning in 1987, M1A1 tanks also received armor packages that incorporated depleted uranium components at the front of the turret and hull.
The M1 is powered by a 1,120 kW (1500 hp) turbine engine that is capable of running on gas or diesel with a fuel capacity of 1900 liters (500 gallons) and an operational range of 426 km (265 mi). The M1 and M1A1 have a a top speed of 67/72 km/h (42/45 mph) on the road and or 40/48 km/h (25/30 mph) off-road respectively.
Merkava IV: The latest MBT of the Israeli Defense Forces, the Merkava and its predecessors have the distinction of being designed with considerable input from soldiers themselves. The fourth variant of the Merkava program, the Mark IV began development in 1999 and entered service by 2004. Like its predecessors, it was designed for rapid repair of battle damage, survivability, cost-effectiveness and off-road performance.
Following the model of contemporary self-propelled howitzers, the turret assembly is located closer to the rear than in most main battle tanks and has the engine in front to provide additional protection against a frontal attack. It also has a rear entrance to the main crew compartment allowing easy access under enemy fire. This allows the tank to be used as a platform for medical disembarkation, a forward command and control station, and an armored personnel carrier.
The Mark IV includes the larger 120 mm smoothbore gun that can the HEAT and APFSDS rounds, using an electrical semi-automatic revolving magazine for 10 rounds. It also includes two 7.62 machine guns for anti-infantry defense. a 60 mm mortar, and a 12.7 mm machine gun for anti-vehicle operations. The tank’s 1112 KW (1,500 hp) turbocharged diesel engine can achieve a top road speed of 64 km/h (40 mph).
Some features, such as hull shaping, exterior non-reflective paints, and shielding for engine heat plumes mixing with air particles are designed to confuse enemy thermal imagers and make the tank harder to spot by heat sensors and radar. It also comes equipped with sectioned, modular armor that can be easily removed and replaced and carries the BMS (Battle Management System) – a centralized system that networks and shares data from all over the battlefield.
T-90: A third-generation MBT that is essentially a modernization of the T-72B and incorporating many of the features of the T-80U, the T-90 is the mainstay of the Russian armed forces. Proposed as a way of creating a single design that would cost less than employing tanks at once, the T-90 sought to marry the mass-production-friendly aspects of the T-72B with the modern amenities of the T-80U. Production began in 1992 and has continued unabated since.
The T-90’s main armament is a 125 mm smoothbore cannon that is capable of firing APFSDS rounds, high-explosive anti-tank (HEAT-FS), and high explosive fragmentation (HE-FRAG) rounds, as well as the Refleks anti-tank guided missile. It also comes with a 12.7mm remotely controlled anti-aircraft heavy machine gun above the commanders hatch and a coaxial 7.62 mm machine gun.
The T-90 is fitted with a “three-tiered” protection system, the first of which is composite armor in the turret that consists of a basic armor shell with an insert of alternating layers of aluminum and plastics and a controlled deformation section. The second tier is third generation Kontakt-5 ERA blocks which, along with sandwiching steel plates and composite filler, make up the turret’s forward armor package.
The third tier is a Shtora-1 (“curtain”) countermeasures suite that includes two electro-optical/IR “dazzlers” on the front of the turret (the distinct Red Eyes), four Laser warning receivers, two 3D6 aerosol grenade discharging systems and a computerized control system. The Shtora-1 warns the tank’s crew when the tank has been ‘painted’ and infrared jammer jams the guidance system of some anti-tank guided missiles.
The tank is powered by a 12-cylinder diesel engine that comes in the 618 kW (840 hp), 746 kW (950 hp), and 930 kW (1250 hp) varieties. Depending on the type of engine, the T-90 has an operational range of 550-700 kms (340-430 mi) and a top speed of 60–65 km/h (37–40 mph).
Type 10 Hitomaru: Designed to replace Japan’s aging Type 90, the Type 10 is a fourth-generation MBT and the second to be entirely developed by Japan for use by the Japan Ground Self-Defense Force. Development began in the 1990’s, the first prototypes being showcased at the 2008 Technology Research and Development Institute (TRDI), and the tank officially entered service with the armed forces by 2012.
In terms of armaments, the Type 10 is believed to use a 120 mm smoothbore gun developed by Japan Steel Works, similar to the L/44, L/50, and L/55 guns licensed by Rheinmetall. The gun is capable of firing all standard 120 mm NATO ammunition, including the newly developed APFSDS round. It also has a roof-mounted 12.7 mm machine gun and a coaxial 7.62 mm machine gun.
The vehicle’s armor consists of modular sections, composed of nano-crystal steel (or Triple Hardness Steel) and modular ceramic composite armor. The tank also has an auto loader which reduces the crew size to three, and comes with day and night sights as standard features. It also has the C4I (Command, Control, Communication, Computer & Intelligence) system which can be incorporated into the JGSDF network to enable sharing of information among units.
The tanks is powered by a 883 kW (12oo hp) V8 Diesel engine that is capable of acheiving speeds of up to 70 km/h (43 mph) in both forward and reverse, and has an operational range of 440 km (273 mi).
Type 99: Also known as ZTZ-99 and WZ-123, and developed from the Type 98, the Type 99 is a third generation main battle tank (MBT) fielded by the Chinese People’s Liberation Army (PLA). Much like its predecessor, the T-99 is designed to compete with both contemporary Russian and western designs. Development began in 2001 and a prototype was unveiled at the China People’s Revolution Military Museum in Beijing during the 2007 Our troops towards the sun exhibition.
The main armament is the 125 mm smoothbore gun which is capable of firing sabot APFSDS, HEAT, and HE-FRAG projectiles, as well as the Soviet AT-11 laser-guided anti-tank missiles and a specially-developed depleted uranium round. It also comes with a remotely operated 12.7 mm machine gun, a commander’s 12.7 mm machine gun, and coaxially-mounted 7.62 mm machine gun.
Though the nature of the Type 99’s armor protection remains classified, it is assumed to be of comparable RHA strength to other third-generation designs, as well as an experimental composite armor known as transparent ceramic. There is also observational evidence that the armor includes modular composite armor that comes in block form, or the addition of ERA blocks.
The Type 99 is powered by a 1100 kW (1500 hp) liquid-cooled diesel engine, with a special (2100 hp) engine for the
Type 99KM model. The tank has a maximum speed of 80 km/h (50 mph) with an operational range of 600 km (373 mi).
Summary/The Future: When looking at the full spectrum of third-generation and fourth-generation tank designs, a few common features become clear. Tanks that were conceived and designed during and after the 1970’s were all intended to take advantage of the latest in tank and anti-tank systems, and for good reason. Since their inception in the second decade of the 20th century, tanks grew in speed, lethality and versatility. Hence, countless systems were devised to knock them out.
In addition to anti-tank rifles and guns that were used throughout the 1920’s and 30’s, these ensuing decades added rockets and rocket-propelled grenades. At the same time, tanks themselves began to sport larger caliber guns with increased range, velocity and more sophisticated warheads. By the 1960’s, optically-tracked and computer-guided missiles were introduced and led to more rounds of innovation.
This led to the introduction of composite armor, which included aluminum alloy, ceramics, depleted uranium, and rolled homogenous steel. This was developed simultaneously with the advent of depleted uranium sabot rounds, shaped charge plasma rounds, and guided missiles that could be fired from a tank gun. Basically, third-generation tanks would combined the ultimate in tank protection and anti-tank weaponry.
Stabilization systems were also introduced along the way which had a revolutionary impact. Prior to their use, tanks were forced to stop driving in order to fire a shot at the enemy, which made them temporarily vulnerable. But with the new stabilizers – as well as targeting computers, night vision, and laser range finders – tanks were now extremely accurate, could fire while on the move, and could engage the enemy day or night.
Today’s fourth-generation tanks take advantage of all of this, and add to it with networking capabilities, more sophisticated computers, and defensive systems that let the crew know when they are being targeted by laser-guided munitions. Armor is also becoming increasingly modular and component-based so tanks can add to their protection or strip down to lighten their loads and increase their speeds.
When it comes to the future of tank warfare, the same forces appear to be at work. Basically, tank systems need to be smarter, stealthier, and more adaptable rather than simply heavier and more lethal. As such, there are numerous projects being developed by DARPA and other defense agencies around the world to create “stealth tanks”, vehicles that would be invisible to thermal imagine and could take advantage of adaptive camouflage to avoid being spotted.
Armata UCP concept
At the same time, there are efforts to create universal combat systems, such as a heavy military vehicle platform that can be fitted to serve in a number of roles. A perfect example of this is Russia’s Armata Universal Combat Platform, a tracked platform will be the basis for a main battle tank, a heavy infantry fighting vehicle, a combat engineering vehicle, an armored recovery vehicle, a heavy armored personnel carrier, a tank support combat vehicle or a self-propelled artillery gun.
With such a system, combat engineers would be able to mount whatever turret or additional components they need to create a vehicle of their choice, one which is suited to the combat role or mission it is expected to perform. This sort of adaptability and versatility also informs ideas for a new class of AFVs (Armored Fighting Vehicles) that would be lighter, more mobile, and could be retrofitted to act as a tank, APC, IFV, command vehicle, or anything else needed.
There are even plans to develop a whole new race of warmachines that would rely on a combination of avoidance, stealth, speed and maneuverability rather than heavy, modular armor for protection. Who can tell which will bear fruit ultimately? At this point though, one thing is clear: in the coming years, tanks will continue to get smarter and become increasingly networked, turning each one into a mobile command and combat platform.
Just months after the Heartbleed bug made waves across the internet, a new security flaw has emerged which threatens to compromise everything from major servers to connected cameras. It is known as the Bash or Shellshock bug, a quarter-century old vulnerability that could put everything from major internet companies and small-scale web hosts to wi-fi connected devices at risk.
Because the bug interacts with a large percentage of software currently in use, and does in ways that are unexpected, Robert Graham – an internet security expert – claims that the Bash bug is bigger than Heartbleed. As he explained it:
And since the bug has existed for some two and a half decades, a great number of older devices will be vulnerable and need to be patched because of it. By contrast, The Heartbleed bug was introduced into OpenSSL more than two years ago, allowing random bits of memory to be retrieved from impacted servers. And according to security researcher Bruce Schneier, roughly half a million websites could be vulnerable.
As Beardsley explained during an interview with CNET:
In the meantime, Graham advised people to do the following:
Ensuring that it is international body would also be advisable. For as the Snowden leaks demonstrated, so much of the internet is controlled the United States. And as always, people need to maintain a degree of vigilance, and seek out information – which is being updated on a regular basis – on how they might address any possible vulnerabilities in their own software.
