The La-250 was intended to be a high-altitude interceptor aircraft developed in the USSR in the 1950s. Problems and a series of crashes led to the improved 'A' version with a slightly drooped nose, delta wings, smaller fuselage but less powerful engines. Note also the separation of the engine intake from the fuselage to improve airflow at supersonic speeds. This La-250A is on display at the Central Air Force Museum.

Supersonic interceptor, missile armed. Approx 4 or 5 were completed. This is the sole survivor.
