(NSI News Source Info) TORONTO, Canada - September 19, 2012: The Chinese military has leaked first photos of a brand new lightweight fighter with external characteristics that allow the jet fifth-generation attribution. Some pictures suggest it could be used on future Chinese aircraft carriers.

Shenyang Aircraft Industry Group (SAC), one of the leading aircraft design and manufacturing corporations of China’s aviation industry, has rolled out a prototype that might eventually become Chinese analogue to America’s F-35.

The aircraft bears a certain resemblance to Lockheed Martin’s F-35 Lightning II, and even reportedly has the codename F-60. Though absolutely no characteristics of the prototype have been unveiled, one major difference is obvious: unlike its American relative, China’s F-60 has two engines.

The pictures of the Chinese technology demonstrator suggest that the engines the aircraft is currently equipped with do not have thrust vectoring nozzles which might suggest the prototype is at too early a stage of testing to get more sophisticated and powerful propulsion package.

Inclined twin vertical tail and wide-spaced ram air inlets are reminiscent of Lockheed Martin’s F-22 Raptor Joint Strike Fighter.

Now it has become obvious that in the race for possession of fifth generation aircraft the Chinese military placed its bets on two horses: Chengdu Aircraft Corporation, which is heavily testing its J-20 “Mighty Dragon” fifth generation heavy fighter-bomber, and Shenyang Aircraft Industry Group with its F-60 lightweight fighter.

The F-60 prototype jet bears the side number 31001, which may be a reference to Chengdu’s J-20 heavy fighter jet. The first two J-20 prototypes have “2001” and “2002” side numbers respectively.

Yet, the F-60 and J-20 are not likely to be regarded as competitors because it appears the aircraft will have different specializations.

China’s future sea-based fighter jet

China’s first aircraft carrier, dubbed Shi Lang, laid down by the Soviet Union in the late 1980s and almost finished now by Chinese engineers, is expected to be put into service by the end of 2012. Still, Beijing has informed the warship will be not ready for action till 2017.

The People’s Liberation Army Air Force (PLAAF) already has fighter jets to form the aircraft wing for Shi Lang. China produces J-15, a copycat of the Soviet-made Su-33. The J-15 copycat has been made by Shenyang Aircraft Industry Group. But the Su-33 was designed in the 1980s and cannot be regarded a proper sea-based aircraft in the 2010s. Probably since SAC already proved it can make a sea-based aircraft, Beijing commissioned a great challenge of creating a fifth generation fighter jet for naval use to this corporation.

Chinese Military Review website has published computer-generated images of the F-60 fifth generation fighter jet in action with a whole range of various air to air missiles. On at least two pictures the aircraft is depicted with an extended arrest hook that the sea-based aircraft use to stop after landing on the deck of an aircraft carrier.

The two-wheeled front rack chassis of the real F-60 prototype also suggests the aircraft is being engineered for naval use, like sea-based versions of Dassault’s Rafale in France, Lockheed Martin’s F/A-18 E/F Super Hornet and the Soviet-made Su-33. At the same time there are no signs the prototype is capable of short take off and vertical landing, which the F-35B STOVL version has.

A brief look at the computer-generated images also exposes another feature the F-60 has in common with Lockheed Martin’s F-35 Lightning II: an extremely limited space in the internal weapon bays. A stealth aircraft must have all of its weapons hidden inside the hull to decrease the aircraft’s visibility to enemy radars. The Chinese F-60, just like the American F-35, can only carry small-sized short range missiles in true stealth mode.

To get seriously armed the F-60 would have to carry long-range missiles externally, which would nullify its stealth capabilities. If so, the F-60 will have limited capabilities.

Probably the biggest problem of the modern Chinese aviation industry is the deadlock with military jet engines it currently finds itself in. For both Chengdu’s J-20 and Shenyang’s F-60 there are no reliable Chinese-made jet engines with technical characteristics appropriate for a fifth generation fighter. Still, Chinese engineers are known not only for copycat efforts, but for outstanding persistence in achieving their objectives.

It cannot be altogether excluded that by 2017, when the Shi Lang aircraft carrier will be commissioned and more warships of the kind be under construction, Chinese engineers will probably decrease or eliminate the dependence on Russian jet engines and spare parts and put the F-60 on a proper flight.

DTN News - RUSSIA DEFENSE NEWS: Russian AF To Get First T-50 Fighters In 2013

Asia News Report: DTN News - RUSSIA DEFENSE NEWS: Russian AF To Get First T-50 Fighters In 2013

(NSI News Source Info) TORONTO, Canada - May 18, 2012: The Russian Air Force will receive the first batch of prototypes of its fifth-generation T-50 fighter for performance testing in 2013, Col. Gen. Alexander Zelin said on Thursday.

The T-50, developed under the PAK FA program (Future Aviation System for Tactical Air Force) at the Sukhoi experimental design bureau, is Russia's first new major warplane designed since the fall of the Soviet Union.

“The work on the fifth-generation fighter is going according to schedule,” Zelin, a former Air Force commander, told a news conference in Voronezh (central Russia). “The third prototype has joined the testing program and the fourth is being built.”

The T-50 made its maiden flight in January 2010 and three prototypes have since been undergoing flight tests.

Zelin earlier said that the number of T-50 aircraft involved in testing would be increased to 14 by 2015.

The fighter was first shown to the public in August 2011, in Zhukovsky near Moscow, at the MAKS-2011 air show.

It has been decided to equip current fighter models with available thrust-vectoring engines. The first batch of upgraded fighters will be handed over to the Air Force by late 2020. It is also planned that all new T-50 fighters will have become operational by then.

“When a plane powered by a regular engine is taken to a wide angle of attack at low speeds, it loses control and stability and starts moving independently of the pilot’s commands, i.e. the plane moves randomly. The Su-35 has perfect controllability at any speed, even at negative speeds, for instance, when the plane drops tail-forward. The pilot can effectively put the plane in any angular position,” Sergei Bogdan, a Su-35 and T-50 test pilot, explained to Izvestiya.

The world’s first thrust-vectoring engine appeared in the export version of the Su-30 meant for India. The first contract for the delivery of such planes was signed more than 10 years ago. India currently operates 150 Su-30 aircrafts and plans to contract the delivery of another 100 machines. Furthermore, Russia supplies Su-30 models powered by these engines to Malaysia and Algeria.

The maiden flight of the T-50 / Project 701 / PAK FA, the first Russian fifth-generation fighter jet was completed successfully on Friday morning, 29 January 2010 at Komsomol'sk-na-Amur. This event is signfincant for several reasons.

The PAK FA is generally similar in appearance to the American F-22, though there are so many differences in detail that it is clearly an original design rather than a knock-off copy. A direct comparison with the F-22 is probably not meaningful on an unclassified basis, but Russian marketers will probably sell it as roughly equivalent in combat potential. While the F-35 is also a fifth generation stealth fighter, the low observable characteristics of this attack aircraft are said to be markedly inferior to the all-around stealth of the F-22 air supremacy fighter.

As of January 2010 a total production run of at least 150-200 aircraft for the Russian Air Force and 200 aircraft for the Indian Air Force was envisioned. If these production objectives are met, the United States might wind up with the world's third largest fleet of stealth fighters, after India and Russia.

In June 2001, India was offered 'joint development and production' of this new 5th generation fighter by Russia. Russia had been trying to sell this concept both to China and India for some time. It seems probable that China declined to participate in this project given a belief that Russia stood to gain more from Chinese participation than did China. That is, it would seem that China had determined that it could produce a superior product without Russian help. With the first flight of the Russian stealth fighter in 2010, an arguably superior Chinese steath fighter might be expected to take to the skies not too long thereafter.

The prospect that a country like Iran might buy even a few dozen PAK FA aircraft from Russia may well awaken interest in the F-22 in Israel, if not Saudi Arabia. The emergence of a Chinese counterpart stealth fighter may also re-awaken Japanese interest in the F-22. Production of large numbers of PAK FA by India would place Pakistan in a rather difficult position, unless it purchased similar numbers of stealth fighters from China.
