Indian aircraft maker Hindustan Aeronautics published on its website some of the technical characteristics of the future fighter FGFA (Fifth Generation Fighter Aircraft), created in cooperation with Russia on the basis of combat aircraft T-50 (PAK FA). According to the description, the Indian version of the aircraft will be network-centric and will be able to act in a group with other FGFA even in areas with "poor communication."
Length of FGFA will be 22.6 meters, height — 5.9 meters and a maximum take-off weight — 34 tons. The aircraft can fly at a distance of 3.88 kilometers and thousands of speeds up to Mach numbers of two (2,3 thousand kilometers per hour). FGFA will be installed on engines with all-aspect thrust vector control nozzle and a maximum deviation of 15 degrees.
Each of the two engines of the fighter will be able to develop a draft of 1400 pounds-force (13.7 kN). Probably, this parameter is incorrect. For comparison, the turbojet engine AL-41F1S (installed on the Su-35S) is able to develop a draft of 8.8 thousand kilograms-force and 15,000 pounds-force in the afterburner mode.
At the end of September 2011, it became known that the command of the Indian Air Force has chosen engines for future fighter, but did not specify what kind. Reported only that the power plants for FGFA will be more powerful than the AL-41F1 ("Article 117"), intended for future fighter T-50.
FGFA will be able to fly at supersonic speed cruising and maneuvering at supersonic speed. In the inner compartment of the fighter can be placed armament of up to 2.25 tonnes and on external pylons — of up to 5.75 tons. The fuselage of the Indian fighter will be carried out with the use of stealth technology. It should be noted that the development of FGFA in the design stage, so many parameters specified HAL, can change in one direction or another. Specifications PAK FA until classified.
The contract for the joint development of FGFA was signed by Russia and India at the end of 2010. The Indian version of the aircraft will be established on the basis of the PAK FA, but will be different from the last version with a single and a double cockpit, engines and avionics. Earlier it was reported that the first flight of FGFA is scheduled for 2015. Air India intend to adopt a 250 fighter FGFA.
