Yakovlev Yak-15

The Yakovlev Yak-15, with the NATO reporting name Feather, was a first-generation Soviet turbojet fighter developed by the Yakovlev design bureau immediately after the Second World War. Its fuselage was that of the piston-engined Yak-3 modified to carry a reverse-engineered German Junkers Jumo 004 turbojet, which the Soviets produced as the Klimov RD-10. Yakovlev adapted two existing prototypes to the RD-10 with little trouble, and one aircraft flew in the August 1946 Tushino flypast. Even before State acceptance trials were completed, the Council of Ministers ordered the type into production in December 1946, with 50 aircraft to be built by April 1947 and split between single-seat fighters and two-seat trainers. The Yak-15 had a tailwheel undercarriage, which led to the tricycle-gear Yak-17.
