Rolled out at Novosibirsk on 25 October 1948 and first flown in January 1949, the Su-15, or Samolet P, was a single-seat all-weather interceptor. It was powered by two 2270kg RD-45F turbojets mounted in tandem, the forward engine exhausting beneath the centre fuselage and the aft engine exhausting via an orifice in the extreme tail. The pilot's pressurised cockpit was offset to port, a tunnel feeding air to the rearmost turbojet passing to starboard. The air intake was surmounted by a radome intended to accommodate Izumrud (Emerald) AI radar, the single-spar wings were sweptback 35° at quarter chord and armament comprised two 37mm cannon. During its 39th flight, on 3 June 1949, the Su-15 developed uncontrollable flutter, its pilot ejecting. At that time a second prototype was still incomplete and the development programme was abandoned.
