Yakovlev Yak 5

In 1944, the Yakovlev OKB of the Soviet Union successfully conducted the maiden flight of the Yakovlev Yak-5, an innovative trainer aircraft that was developed for experimental purposes.

In 1944, the Soviet Air Forces utilized the Yakovlev UT-2 as their standard primary trainer.

However, due to its simplistic design, pilots encountered difficulties when transitioning to more advanced aircraft.

To address this issue, the Yakovlev design bureau developed the UT-2L, a more sophisticated derivative featuring an enclosed tandem cockpit, flaps, and blind flying instruments.


Concurrently, the Yakovlev team also designed the Yak-5, a single-seat aircraft intended as a fighter-trainer.

The Yak-5 was a low-wing monoplane constructed of wood and featured an enclosed sliding canopy over the rear cockpit, with the front cockpit removed.

The UT-2’s fixed landing gear was replaced with a retractable tailwheel undercarriage.

The aircraft was powered by a Shvetsov M-11D five-cylinder radial engine producing 115 hp (86 kW) and a two-bladed variable-pitch propeller.

It could be equipped with a single synchronized ShKAS machine gun aimed by a reflector sight, and a radio was also installed.

The inaugural flight of the Yak-5 prototype took place on 7 September 1944.

The test pilots expressed great satisfaction with the manoeuvrability of this novel fighter-trainer, and it successfully underwent official assessment.

Ultimately, the UT-2L and Yak-5 models did not proceed to mass production due to the perception within the Soviet Air Force command that wooden aircraft were becoming outdated.


Consequently, the Yakovlev Yak-18 trainer, constructed entirely from metal, was chosen for production in late 1945.

Tragically, the sole Yak-5 met its demise when a catastrophic failure of its wooden wing occurred during a snap roll, leading to a fatal crash.
