The Mikoyan MiG-LMFS (Lyogki Mnogofunkzionalny Frontovoi Samolyot = Lightweight Multirole Frontline Aircraft ), is an in-development Russian Multirole Aircraft, based on the MiG 1.44, after the failure of "Project R-33", the MiG-LMFS is the second try of Mikoyan-Gurevich ( newly RAC MiG ) to develop a replacement for the aging Mikoyan MiG-21 and Mikoyan MiG-23.
After the failure of the MiG 1.44 RAC MiG searched ways to use the new knowledge and technology otherwise. As Sukhoi was chosen to develop the heavy Air-Superiority Fighter PAK-FA, Mikoyan started to develop a new leightweight Multirole combat aircraft, the MiG-LMFS, which is also called "Project 1.27". Actually the MiG-LMFS is only a single engine stealth variant of the Mikoyan-Gurevich MiG 1.44. While the PAK-FA challenges the Lockheed Martin F-22 Raptor, the Mikoyan-LMFS is a direct competitor to the American F-35 Lightning II. Like on the MiG-1.44, Canards and tailless delta-wings will be used.
But at the beginning of 2011 RAC MiG published new concept designs of the LMFS, but this time, unlike on earlier designs, Diverterless Supersonic Inlets were included like they are on the F-35 Lightning II and the Chinese Chengdu J-20, and instead of Canards, conventional control surfaces are used.
RAC MiG is excepted to design the MiG-LMFS as a smaller and cheaper alternative to the heavy and expensive Sukhoi Fighters. Beacause of the MiG-23, MiG-21 and MiG-27, which are used in many countries and they must be replaced, the MiG-LMFS could be very successful on global market. The problem is that it is unknown if the Russian Air Force will want the LMFS, while it is impossible for Mikoyan to finance itself only with the MiG-29 and the MiG-35. But because the Sukhoi PAK-FA will have technical problems and will get more expensive, like the American F-22 Raptor, the LMFS, like the F-35 in the United States, could be very interesting for the Russian Air Force.
The performance of the LMFS is still unknown, but when looking on it´s design, it can be estimated against which aircraft it will compete and against which it will not:
