For the duration of its evaluation phase at Wright-Patterson, the Yak-23 was given the Buzz No FU-599 and serial 0599.

A tractor gives scale to the diminutive Yak-23.

The clean lines of the Yak-23 are evident in this side view of the aircraft. The dark area at the base of the air intake is the gun muzzle fairing panel.

The Yak-23 was designed to meet a 1946 demand for a new-generation fighter, using existing airfields and facilities. An extraordinarily short design period was achieved by utilising major features from existing aircraft - the wing and undercarriage of the Yak-19, for example.
