Mikoyan LMFS

The Mikoyan LMFS (Микоян ЛМФС) is a proposed Russian stealth, single-engine fighter aircraft, loosely based on the canceled Mikoyan Project 1.44. Recent images reveal a fighter design with substantially larger internal weapons bays.

Design
Developed by the United Aircraft Corporation or UAC, this lightweight fighter is believed to incorporate an engine based on the RD-33 engine, and manufactured at the Klimov factory. The engine is supposed to be fifth generation, utilizing the latest advancements in turbine and combustion chamber technology, and only receiving minor changes to the fan blades.
