Su-11
The Sukhoi Su-11 (NATO reporting name: "Fishpot-C") was an upgraded version of the delta-wing Sukhoi Su-9 ("Fishpot") interceptor, which took its roots from the company's swept wing Su-7 fighter bomber. The Su-11 entered service with the Soviet Air Force/Air Defense Troops (VVS/PVOS) in mid 1960s and remained in operational status until early 1980s.
The Su-11, as with Su-9 which it descended from, had the same basic configuration with the definitive MiG-21 "Fishbed" air superiority fighter, by having a cigar shaped fuselage, a circular intake around a sharp spike which housed the avionics suite and delta wings with a conventional swept back tail assembly, featuring all-moving horizontal stabilizers. However, the "Fishpot" was substantially heavier and featured no cannon armament, as with most other interceptors of that particular timeframe.
The Su-11 was powered by a Lyulka AL-7F-1 afterburning turbojet, an improved version of the AL-7 used in the Su-9. The new turbojet gave the "Fishpot-C" 2210 lbf (9,830 N) more thrust in afterburner, which greatly improved the aircraft's climb rate and top speed. The aircraft also adopted an improved version of the Su-9 fire control system and radar and was equipped with refined variants of the AA-3 "Anab" Air-to-Air Missiles (AAMs).
A conversion trainer version, the Su-11U "Maiden" has also been developed, though details are unclear.
