Mikoyan LMFS
The Mikoyan LMFS (Russian: Микоян ЛМФС) Liogkiy Mnogofunktsionalniy Frontovoi Samolyet (LMFS)—or Light Multi-Function Frontline Aircraft, also known as the MiG-XX, was a proposed light Russian single-seat all-weather stealth multirole combat aircraft. The design is derived from the company's PAK FA proposal, which was rejected in favor of Sukhoi's, along with lessons learned from the cancelled Mikoyan MiG-1.42/1.44.
