The Mikoyan-Gurevich MiG-9 was the first turbojet fighter developed by Mikoyan-Gurevich in the years immediately after World War II.
It used reverse-engineered German BMW 003 engines.
Categorized as a first-generation jet fighter, it was moderately successful, but suffered from persistent problems with engine flameouts when firing its guns at high altitudes due to gun gas ingestion.
