Sukhoi Su-9 (K)

Displaying a close conceptual similarity to the Messerschmitt Me 262, the Su-9 single-seat fighter, also known as Samolet (Aircraft) K, entered flight test in the autumn of 1946. Of all-metal construction with a semi-monocoque, oval-section fuselage and single-spar wings, the Su-9 had an armament of one 37mm and two 23mm cannon, and was powered by two 900kg Junkers Jumo 004B turbojets (which had been copied for manufacture in the Soviet Union as the RD-10). The Su-9 embodied a number of innovatory features insofar as Soviet technology was concerned, these including hydraulically-boosted control surfaces, a cordite-fired ejection seat, a variable-incidence tailplane, provision for assisted take-off rockets and a braking parachute. Racks under the centre fuselage permitted carriage of one 500kg or two 250kg bombs. The Su-9 was shown publicly over Tushino on 3 August 1947, and with completion of State testing in the following December, series production was recommended. However, although possessing no more than a superficial resemblance to the Me 262, its configurational similarity to the German fighter was a stigma which led Yosif Stalin to reject the Su-9 out of hand.
