User Countries USSR
  • Yak-41 ( product 48 ) - the project of the supersonic deck fighter GDP, work on which began in 1973.
  • Yak-41UT ( product 48U ) - training version Yak-41 with an extended fuselage and tandem seating pilots.
  • Yak-41M / Yak-141 ( product 48M ) is a project of multipurpose VTOL as a ship and land based on the basis of developments in VTOL Yak-41. Due to the backlog in terms of development, the aircraft in 1988 received a new designation Yak-141. It was built 4 copies of the Yak-141, including one pre-series. Serial production of Yak-141 did not take place due to the termination of financing in 1992.
  • Yak-43 ( product 201 ) - a shortened takeoff and landing aircraft (SUVP), a "land" version of the Yak-41 with an enlarged wing area and an NK-32 engine with a swivel nozzle.
  • Yak-201 is a 5th generation aircraft project based on the Yak-141 VTOL, designed by Yakovlev Design Bureau on its own initiative and at its own expense in the mid-1990s. It is executed with a canard scheme with use of technologies to decrease radar visibility. The power plant was to include a new PMD with a maximum thrust of 17,500 kgf and a mechanical drive to the lift fan. The aircraft was supposed to have a lifting mass of 21,500 kg (including 6,000 kg of fuel) and a combat load of up to 4200 kg. The combat radius of the new VTOL was to be 2,400 km with a combat load of 1 ton and 900 km with a combat load of 2 tonnes. It was planned to use new weapons systems and avionics. Participated in the competition on the LFI program (the creation of an easy front-line fighter for the Russian Air Force), but was not accepted by the customer.
