History JSC A.S. Yakovlev Design Bureau
Yakovlev Yak-15
( NATO reporting name: Feather),USAF/DOD designation Type 2
The Yakovlev Yak-15 (Russian: Яковлев Як-15; NATO reporting name: Feather, USAF/DOD designation Type 2) was a first-generation Soviet turbojet fighter developed by the Yakovlev design bureau (OKB) immediately after World War II. The main fuselage was that of Yakovlev Yak-3 piston-engine fighter modified to mount a reverse-engineered German Junkers Jumo 004 engine. The Yak-15 and the Swedish Saab 21R were the only two jets to be successfully converted from piston-power to enter production. 280 aircraft were built in 1947. Although nominally a fighter, it was mainly used to qualify piston-engine-experienced pilots to fly jets.
Design and development
Survivors
Only one Yak-15 survives, 'Yellow 37' at the Vadim Zadorozhny Technical Museum outside Moscow. It was purchased by the technical museum when the Yakovlev OKB's museum was liquidated in 2006.
Variants
Data from: OKB Yakovlev
- Yak-Jumo (Yak-3-Jumo): The first prototypes of the Yak-15 series, powered by captured Jumo 004 engines.
- Yak-15-RD10: (also referred to as Yak-RD) Initial designation of prototypes and early production aircraft powered by Soviet-built RD-10 engines (copies of the Jumo 004), with no or reduced armament.
- Yak-15: Production aircraft with full armament
- Yak-21: Two-seat training version of Yak-15. One built, but not proceeded with because of the success of the trainer version of the Yak-17.

On 29 April 1946, five days after the Mikoyan-Gurevich I-300 (MiG-9 Prototype) and the Yak-Jumo made their first flights, the Council of Ministers ordered that the Yakovlev OKB begin design of a new aircraft similar to the Yak-Jumo, using the RD-10 engine with improved aerodynamics. This generally resembled the original aircraft, but the wings were entirely redesigned with laminar flow airfoils, the tail structure was enlarged and an ejection seat was fitted.

On 9 April 1945, the Council of People's Commissars ordered the Yakovlev OKB to develop a single-seat jet fighter to be equipped with a single German Jumo 004 engine.
