(NSI News Source Info) TORONTO, Canada - October 25, 2012: Earlier this year pictures came out of China showing yet another stealth fighter prototype. This one is called the J-31 “Falcon Eagle” (from an inscription on the tail), and while it looks like the American F-22, it’s also smaller than China’s other stealth fighter (the J-20, which has already flown). The J-31 was built by the Shenyang Aircraft Corporation (which makes the J-11, the illegal Chinese copy of the Russian Su-27). The J-31 has some characteristics of the F-35 as well but appears more an attempt to match the F-22. It’s possible that the F-31 was a competing (with the J-20) design that lost out. That’s because the J-31 has not flown yet. Whatever the case, the J-31 is further evidence that China is determined to develop its own high tech military gear. 

While China is eager to develop advanced military technology locally, it recognizes that this takes time and more effort than nations new to this expect. Thus China is trying to avoid the mistakes Russia made in this area, and having competing designs and developing necessary supporting industries is part of that. All this takes a lot of time and involves lots of little (and some major) failures. The Chinese are doing it right and are willing to wait until they get military tech that is truly world class.

The other stealth fighter, the J-20, was made by CAC (Chengdu Aircraft Company), which also produced the JF-17 and J-10. The J-20 made its first flight over a year ago and several more since then. A second J-20 prototype has also been seen and first flew last May. While the J-20 looks like the American F-22 when viewed head on, it's overall shape, weight, and engine power is closer to the American F-15C. In other words, it's about 20 meters (62 feet) long, with a wing span of 13.3 meters (42 feet). J-20 has about the same wing area as the F-15C, which is about 25 percent less than the F-22 (which is a few percent larger than the F-15 in terms of length and wingspan). Worse, for the J-20, is the fact that its engine power is about the same as the F-15C, while the F-22 has 65 percent more power. With the afterburner turned on, the J-20 has more power than the F-15C and nearly as much as the F-22. But because the afterburner consumes so much fuel, you can't use more than a few minutes at a time. The F-22 is still one of only three aircraft (in service) that can supercruise (go faster than the speed of sound without using the afterburner). In addition to the F-22, the Eurofighter and the Gripen can also supercruise.

The J-20 has some stealthiness when it's coming at you head on. But from any other aspect, the J-20 will light up the radar screen. For this reason the J-20 is seen as a developmental aircraft, not the prototype of a new model headed for mass production. As such, it is only the fifth stealth fighter to fly, the others being the U.S. F-22 and F-35, plus the Russian T-50 and I.42. The older U.S. F-117 was actually a light bomber and the B-2 was obviously a heavy bomber. Based on recent Chinese warplane development projects (J-11 in particular), the J-20 has a long development road ahead of it and will likely change size and shape before it reaches the production design. The J-31 may be an insurance policy, in case the J-20 effort goes off the rails in a big way.

While the shape of the J-20 confers a degree of stealthiness (invisibility to radar), even more electronic invisibility comes from special materials covering the aircraft. It's not known how far along the Chinese are in creating, or stealing, these materials, or the needed engines. The current J-20 engines are sufficient for early flight tests but not capable of providing the supercruise, something that would be essential for the J-20. That's because China would most likely use the aircraft singly, or in small groups, to seek out and attack American carriers. As for F-22 class engines, that is being worked on. Two years ago China announced it was developing the WS-15 engine (since the 1990s), a more powerful beast well suited for the J-20. No date was given as to when the WS-15 would be available for use or whether it would have the same vectoring (ability to move the hot jet exhaust in different directions in order to make the fighter more maneuverable) the F-22 uses.

For the J-20 to be a superior fighter, it would need electronics (including radars and defense systems) on a par with the F-35 and F-22. So far, the Chinese have not caught up with stuff used by current American fighters. But the gap is being closed, faster than it was during the Cold War when the Russians were creating, or stealing, their way to military tech equivalence with the West. The Russians never made it but the Chinese believe they can succeed.

Work on the J-20 began in the late 1990s, and the Chinese knew that it could be 25 years or more before they had a competitive stealth fighter-bomber. The J-20 is being tested in central China. The twin engine J-20 appears to be about the same weight as the 30 ton F-15C. The F-35A is a 31 ton, single engine fighter, while the twin-engine F-22 is slightly larger at 38 tons. The Russian I.42 was a 42 ton aircraft and their T-50 weighed in at 37 tons.

China is also developing other support technologies, like the AESA radar, highly efficient cockpit, stealth, and software to tie everything together. Developing, or even copying, this tech is not easy. But the Chinese already know that, having decades of experience adapting stolen technology to their needs. Thus it appears that China is planning on having the J-20, in some form, ready for service by the end of the decade. The key factor is their ability to develop or steal the needed technology by then. The J-20 appears to be a fighter-bomber, as this kind of aircraft would be most useful dealing with the U.S. Navy and key targets in Taiwan or Japan. In any event, the J-20 is an attempt to develop some kind of 5th generation aircraft, complete with stealth.

The only other competitor in this area is Russia, where fifth generation fighter developments were halted when the Soviet Union disintegrated in 1991. Actually, all development work on new fighters, by everyone, slowed down in the 1990s. But work on the F-22, F-35, Eurofighter, and Rafale continued, and those aircraft became, in roughly that order, the most advanced fighter aircraft available today. MiG resumed work on the I.42 in the 1990s, but had to stop after a few years because of a lack of money. Sukhoi has never stopped working on its T-50, funded by much higher sales of its Su-27/30 fighters. This fifth generation may come to be called the "last generation," after they are replaced by the second generation of pilotless combat aircraft (counting armed Predators and the like as the first).

DTN News - MAURITANIA DEFENSE NEWS: Mauritania Receives Brazilian-Made Super Tucano Jet Fighter

DTN News - MAURITANIA DEFENSE NEWS: Mauritania Receives Brazilian-Made Super Tucano Jet Fighter

(NSI News Source Info) TORONTO, Canada - October 25, 2012: Mauritanian Air Force has received its first Brazilian-made Super Tucano jet fighter under a military deal passed last march with the aircraft manufacturer Embraer, without saying how many planes will be delivered to the African nation.

However, some foreign diplomatic and intelligence sources say that Mauritania will be supplied at least three EMB-314 Super Tucano light military planes which can be used for pilot training, reconnaissance, internal security, border patrol and counter-terrorism and anti-narcotics trafficking missions.

Equipped with an advanced laser inertial navigation and attack system, a GPS and a traffic alerting and collision avoidance system (TCAS), the Super Tucano has an integrated advanced weapon system. This includes  a centerline hard-point for air-to-surface weapons beneath the fuselage, besides wing-embedded cannons.

The aircraft also includes the Safire thermal imaging system from FLIR, which allows the aircraft to carry out night surveillance and attack missions. Powered by a PT6A-68A turboprop engine developing 969kW, the aircraft can fly at a maximum speed of 560km/h. It is also capable of operating from remote bases and unpaved runways.

Designed to operate in high temperature and humidity conditions in extremely rugged terrain, the Super Tucano is highly maneuverable, has a low heat signature, and incorporates 4th generation avionics and weapons systems. It is currently used by the air forces of Brazil, Dominican Republic, Colombia, Ecuador, Chile, Burkina Faso, Indonesia, and has been ordered by the armies of Guatemala and Angola.

Mauritania, which has a population of 3.5 million, is facing growing terrorist threats in the Sahel region which has become a safe haven for organized crime and terrorist networks.

After the Islamist extremists took control of Northern Mali, thousands of refugees fled into Mauritania, placing additional strain on resources as the country is itself rocked by internal turmoil and struggling with a food crisis engulfing the whole Sahel region.
