The Lavochkin La-9 was a Soviet fighter aircraft produced shortly after World War II. It was one of the last piston engined fighters to be produced before the widespread adoption of the jet engine.

The Lavochkin La-7 was a piston-engined single-seat Soviet fighter aircraft developed during World War II by the Lavochkin Design Bureau. It was a development and refinement of the Lavochkin La-5, and the last in a family of aircraft that had begun with the LaGG-1 in 1938. Its first flight was in early 1944 and it entered service with the Soviet Air Forces later in the year. A small batch of La-7s was given to the Czechoslovak Air Force the following year, but it was otherwise not exported. Armed with two or three 20 mm (0.8 in) cannon, it had a top speed of 661 kilometers per hour (411 mph). The La-7 was felt by its pilots to be at least the equal of any German piston-engined fighter. It was phased out in 1947 by the Soviet Air Force, but served until 1950 with the Czechoslovak Air Force.
