Sukhoi/HAL FGFA Sukhoi/HAL FGFA The Sukhoi/HAL Fifth Generation Fighter Aircraft (FGFA) or Perspective Multi-role Fighter (PMF) was a fifth-generation fighter aircraft planned for India and Russia. It was a derivative project of the Russian Sukhoi Su-57 for the Russian Air Force. The FGFA was the earlier designation for the Indian version, while the combined project is called the Perspective Multi-Role Fighter (PMF). The completed FGFA was to include a total of 43 improvements over the Su-57, including stealth, supercruise, advanced sensors, networking and combat avionics. The Indian version would have been a two-seater with pilot and co-pilot or weapon systems operator (WSO).
Sukhoi Su-15 the Su-15 was abruptly retired from the new Russian Air Force in 1993 to comply with the Treaty on Conventional Armed Forces in Europe. Most were hastily scrapped in favour of more advanced interceptors, including the Su-27 and MiG-31, but some are in reserve storage for emergency use. In Ukraine, the last Su-15s (at Kramatorsk and Belbek) were withdrawn from use in 1996. Some Western reports indicate that the Su-15TM was also designated Su-21 and the Su-15UM Su-21U. These reports are apparently incorrect. Designation Su-21 was reserved for Su-17M4 but never used. Sukhoi Su-15 The Sukhoi Su-15 (NATO reporting name:
