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 dead-stick 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).Yakovlev Yak-1

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.[
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 Novosibirsk, while the Su-3 was destroyed within the city of Novosibirsk during the ]Great Patriotic War
