Post-PFI Soviet/Russian aircraft projects
The Soviet post-PFI projects are several Soviet and Russian Air Force projects initiated to replace the PFI-era aircraft.
The result of the LPFI project was the Mikoyan MiG-29 Fulcrum.
The result of the TPFI project was the Sukhoi Su-27 Flanker.
The Su-47 was developed by Sukhoi to match the MiG 1.44.
Yakovlev proposed the Yak-133, a modified version of this Yak-130.
The Sukhoi Su-57 is a twin-engine stealth multirole fighter aircraft developed by Sukhoi. It is the product of the PAK FA programme, which was initiated in 1999 as a more modern and affordable alternative to the MFI. Sukhoi's internal designation for the aircraft is T-50. The Su-57 is the first aircraft in Russian military service designed with stealth technology and is intended to be the basis for a family of stealth combat aircraft.
