The SAM-13 was designed at OKB 31 by a team under Aleksandr Sergeevich Moskalyev. The project begain in 1938, probably after Moskalyev saw the Fokker D.XXIII mockup presented at the International Air Show at Paris-Le Bourget in 1938.
The aircraft was entirely made of wood and had an unusual appearance, with twin tail booms, a feature shared by the D.XXIII and Lockheed P-38. The cockpit was located at the wing leading edge, providing excellent visibility.
Empty weight was only Template:Convert. It made just two test flights, piloted by Nikolay Fikson, at the end of 1940, achieving a maximum speed (at sea level) of Template:Convert and Template:Convert at Template:Convert.
Problems were encountered during the tests, prop wash issues arising due to the rear propeller being too close to the elevators. Cooling of the rear engine was troublesome, and during take-off and landing, debris from the landing gear wheels was thrown up, damaging the cooling system.
Development was interrupted by the German invasion and, despite its promising performance, was never resumed.
