The Sukhoi Su-1 or I-330 (Russian: Сухой Су-1) was a prototype Soviet high-altitude fighter aircraft built at the beginning of World War II. An improved version, designated Su-3 (I-360), was also built and tested the following year. Neither version was mass-produced.[1]

Development

In 1939, Sukhoi was tasked with designing a high-altitude fighter, the resulting Su-1 was a conventional

Kharkov in May 1940, flying for the first time, on 15 June 1940, with A.P. Chernyavsky at the controls. Testing continued until 3 August, when Chernavskii mistakenly landed with the landing gear retracted. After the completion of repairs in mid-September, testing resumed, but an in-flight engine failure on 2 October resulted in a deadstick landing. Limited flight testing continued until April 1941, with the Su-1 reaching a top speed of 641 km/h (345 kn, 400 mph) at 10,000 m (32,810 ft).[2] However, the turbochargers proved unreliable and without them the aircraft was inferior in performance to the Yakovlev Yak-1.[3]

Su-3

The second Su-1 prototype, built as the Su-3, differed in having a revised wing section with wing area reduced to 17 m² (183 ft²). Completed in 1941, the Su-3 demonstrated better performance than the Su-1, but suffered from continuing problems with the TK-2 turbochargers.[2] Further development was cancelled on 16 April 1941, when production of reliable TK-2 turbo-chargers was delayed.[1]

The fate of the two prototype aircraft is uncertain. According to some reports, the Su-1 was destroyed during the bombing of a train near
