Drone Wars: China’s Rainbow Drone Unveiled

CH-4RainbowAs part of their ongoing efforts to become a world power, China has spared no investment when it comes to the development of Unmanned Aerial Vehicle (UAV) technology. And after several successful missile tests, the People’s Liberation Army (PLA) is all set to receive the next-generation aerial drone. Known as the CH-4, the development of this UAV is just the latest in China’s attempt to catch up to western developers.

Although China’s drone technology may be several years behind top manufacturers in the US and Israel, the country’s UAV manufacturers are hoping that their mid-range prices and middling technology will lure potential customers from developing nations. During the unveiling, which took place at the beinnial Zhuhai Air Show in late August, officials from Kenya, Russia and other countries were on hand to witness this an other examples of China’s exportable UAVs.

CH-4Rainbow2 Representatives from China Aerospace Long-March International, a division of the state-owned China Aerospace Science and Technology Corporation (CASC), were on hand at the presentation and spoke with relative candor about the CH-4 and two other drones the company was showing for the first time. Guo Qian, a director at a division of CASC, when talking about the interest and marketability of the company’s military grade drones, had the following to say:

We’ve been contacting many countries, especially from Africa and Asia. They are quite interested in the intermediate and short-range UAVs because they are portable and low-cost.

Similarly, Li Pingkun , the head of the Rainbow 4 project at the aerospace corporation, told state television the drone could make a long-distance hit on a target with a margin of error of less than 1.5 metres. He said the system was very precise because it used several methods to guide missiles or smart bombs to their target. As he told ChinaNews, the drone is “well-positioned to carry out the subsequent missions.”

CH-4Rainbow1The unveiling of this drone comes at a time when the PLA is actively and publicly promoting the use of drones by its military personnel. During the show, the CASC also displayed a handful of smaller short range drones and set up a flashy ground-to-ceiling UAV attack simulation compete with a dozen technicians glued to computer screens in a the make-believe war room. As Guo explained:

Our company has set up a pretty aggressive sales target for UAVs, but the global market competition is quite fierce. There are many similar products in the global market and they are quite mature, so we haven’t had a big impact in the market. It will take some time for our products to be known and accepted.

The Rainbow 4 is the CASC’s latest creation, and is intended to act as the PLA’s answer to the MQ-9 Reaper – a hunter-killer drone mainly used by the US military for reconnaissance and high-precision air strikes. The CH-4 can carry a payload of 345 kg (760 lbs) of missiles of precision-guided bombs, can reach an altitude of 8 km (26000 feet), has a range of 3,500 kilometers, and fly for up to 30 hours depending on how heavy a payload it is carrying.

China_dronetestHowever, it remains much slower than the Reaper, which can fly at a top speed of 482 km/h compared to the Rainbow’s 235 km/h. In addition, the MQ-9 has a much higher payload of 1700 kg  (3800 lbs), which works out to six Hellfire missiles or precision-guided bombs. And while it has greater range – 3000 km vs. the MQ-9’s 1850 km – the Reaper has a service ceiling of up to 18,000 meters.

The PLA also has limited experience in using drones in combat zones; whereas for the USAF, drone use has become second nature. But above all, the most glaring aspect of the “drone gap” is the fact that this latest Chinese drone was not the result of indigenous design or innovation. Much like other aspects of China’s stealth and weapon’s development, it is the result of mimicry.

Beyond the US, NATO, Israel, Russia and China, middle powers like India, Pakistan, Brazil and various Sub-Saharan African nations are likely to have their own soon. In addition, certain “rogue states” – i.e. Iran, North Korea, Syria – are likely to have their own as well.

The term “Drone Wars” is likely to become very literal as a result!

The Future of Flight: VR Fighter Pilot Training

f-35sThe latest breeds of military aircraft are naturally smarter, faster, and more stealthy than their predecessors. Known as Fifth Generation craft, they are designed to incorporate numerous technological advances – like Low Probability of Intercept Radar (LPIR), supersonically launched guided missiles, a wealth of sensors, highly-integrated computer systems that provide full situational awareness, and automated targeting.

The problem is, these planes are too powerful to be trusted to the untrained. This creates a paradoxical situation where  recruits have to learn how to fly them before they can be allowed to fly them. This is especially so during Red Flag training, where pilots take part in advanced aerial combat exercises intended to prepare roughly 27,000 pilots and engineers for warfare every year.

Sen. Daniel K. Inouye memorial service in HawaiiThe solution, according to General Mike Hostage, is to train pilots in virtual reality in every facet of fifth generation fighter jet technology. It’s what is known as “Live Virtual Constructive” (LVC) training, which the military is increasingly turning to because it is a major cost saver.  Every branch is feeling the financial squeeze, and simulated training is a popular idea since it cuts down on the time it takes to get a pilot airborne and the cost of launching a jet.

As Hostage explained during an Air Force Association speech back in July:

The fifth generation brought us capabilities and lethalities that are straining my abilities at Red Flag to produce that same realistic combat environment. I can’t turn on every bell and whistle on my new fifth-generation platforms because a) they’re too destructive, and b) I don’t want the bad guys to know what I’m able to do… I will still do Red Flags, I will still do live training in live platform. But the place where I will be able to take the gloves off, the place where I can turn on all the bells and whistles and get full capability is going to be in the virtual constructive arena.

AFAMSIn addition to the cost-saving benefits, the US Air Force has embraces the technology thanks in no small part to the new head of the Air Force Agency for Modeling and Simulation (AFAMS), where much of the research into virtual reality training is being done. Colonel Franz Plescha, who was instituted as the agency’s new commander back in July, is a committed futurist who believes there is great potential in warfighting simulation technology.

A graduate of the United States Air Force Academy in 1987, Plescha’s most recent assignment (from July 2010 to June 2013) was as the Commander of the Warrior Preparation Center of the Einsiedlerhof Air Station in Germany. Here, he became intimately familiar with the kind of software and simulations that are designed to help commanders simulate the conduct of combat operations without ever having to put lives in danger.

F-22A_Raptor_-03-4058As he made clear, upon taking the helm at AFAMS, he refuses to waste any time on making the integration happen:

I personally believe the differences between live and simulation will continue to blur. Live or simulation? What’s the difference? What we call simulation today will become so real, it may actually influence our enemies in the future. Just imagine how that could change combat in the future.

But of course, one has to wonder if this vision is not already here, since digitally-assisted situational awareness, unmanned drones and cyber warfare are already present in militaries the world over. And as all other aspects of combat training become increasingly digitized, the distinction between simulation and warfare are themselves likely to become increasingly blurred.

Drone Wars: Bigger, Badder, and Deadlier

UAVsIn their quest to “unman the front the lines”, and maintain drone superiority over other states, the US armed forces have been working on a series of designs that will one day replace their air fleet of Raptors and Predators. Given that potential rivals, like Iran and China, are actively imitating aspects of these designs in an added incentive, forcing military planners to think bigger and bolder.

Consider the MQ-4C Triton Unmanned Aerial System (UAS), a jet-powered drone that is the size of a Boeing 757 passenger jet. Developed by Northrop Grumman and measuring some 40 meters (130 feet) from wingtip to wingtip, this “super drone” is intended to replace the US Navy’s fleet of RQ-4 Global Hawks, a series of unmanned aerial vehicles that have been in service since the late 90’s.

Triton_droneThanks to a sensor suite that supplies a 360-degree view at a radius of over 3700 kms (2,300 miles), the Triton can provide high-altitude, real-time intelligence, surveillance and reconnaissance (ISR) at heights and distances in excess of any of its competitors. In addition, the drone possess unique de-icing and lightning protection capabilities, allowing to plunge through the clouds to get a closer view at surface ships.

And although Triton has a higher degree of autonomy than the most autonomous drones, operators on the ground are still relied upon to obtain high-resolution imagery, use radar for target detection and provide information-sharing capabilities to other military units. Thus far, Triton has completed flights up to 9.4 hours at altitudes of 15,250 meters (50,000 feet) at the company’s manufacturing facility in Palmdale, California.

?????????????????????????????????Mike Mackey, Northrop Grumman’s Triton UAS program director, had the following to say in a statement:

During surveillance missions using Triton, Navy operators may spot a target of interest and order the aircraft to a lower altitude to make positive identification. The wing’s strength allows the aircraft to safely descend, sometimes through weather patterns, to complete this maneuver.

Under an initial contract of $1.16 billion in 2008, the Navy has ordered 68 of the MQ-4C Triton drones with expected delivery in 2017. Check out the video of the Triton during its most recent test flight below:


But of course, this jetliner-sized customer is just one of many enhancements the US armed forces is planning on making to its drone army. Another is the jet-powered, long-range attack drone that is a planned replacement for the aging MQ-1 Predator system. It’s known as the Avenger (alternately the MQ-1 Predator C), a next-generation unmanned aerial vehicle that has a range of close to 3000 kms (1800 miles).

Designed by General Atomics, the Avenger is designed with Afghanistan in mind; or rather, the planned US withdrawal by the end 0f 2014. Given the ongoing CIA anti-terrorism operations in neighboring Pakistan are expected to continue, and airstrips in Afghanistan will no longer be available, the drones they use will need to have significant range.

The Avenger prototype made its first test flight in 2009, and after a new round of tests completed last month, is now operationally ready. Based on the company’s more well-known MQ-9 Reaper drone, Avenger is designed to perform high-speed, long-endurance surveillance or strike missions, flying up to 800 kms (500 mph) at a maximum of 15,250 meters (50,000 feet) for as long as 18 hours.

Compared to its earlier prototype, the Avenger’s fuselage has been increased by four feet to accommodate larger payloads and more fuel, allowing for extended missions. It can carry up to 1000 kilograms (3,500 pounds) internally, and its wingspan is capable of carrying weapons as large as a 2,000-pound Joint Direct Attack Munition (JDAM) and a full-compliment of Hellfire missiles.

Avenger_drone1Switching from propeller-driven drones to jets will allow the CIA to continue its Pakistan strikes from a more distant base if the U.S. is forced to withdraw entirely from neighboring Afghanistan. And according to a recent Los Angeles Times report, the Obama administration is actively making contingency plans to maintain surveillance and attacks in northwest Pakistan as part of its security agreement with Afghanistan.

The opportunity to close the gap between the need to act quickly and operating from a further distance with technology isn’t lost on the US military, or the company behind the Avenger. Frank Pace, president of the Aircraft Systems Group at General Atomics, said in a recent statement:

Avenger provides the right capabilities for the right cost at the right time and is operationally ready today. This aircraft offers unique advantages in terms of performance, cost, timescale, and adaptability that are unmatched by any other UAS in its class.

??????????????????????????????What’s more, one can tell by simply looking at the streamlined fuselage and softer contours that stealth is part of the package. By reducing the drone’s radar cross-section (RCS) and applying radar-absorbing materials, next-generation drone fleets will also be mimicking fifth-generation fighter craft. Perhaps we can expect aerial duels between remotely-controlled fighters to follow not long after…

And of course, there’s the General Atomic’s Avenger concept video to enjoy:
