Development
In 1939, Sukhoi was tasked with designing a high-altitude fighter, the resulting Su-1 was a conventional monoplane
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple wings.
A monoplane has inherently the highest efficiency and lowest drag of any wing con ...

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).
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
