Sukhoi Su-11

The Sukhoi Su -11 (Russian Сухой Су -11, NATO reporting name: Fishpot -C) was a Soviet interceptor from the 1960s.

Development

The Su -11 is a modernized version of the Sukhoi Su -9 ( Fishpot ) with improved engine, the new Oryol radar and modified armament. After extensive experiments with new variants of the T-3, as PT -7, PT -8 and designated T-47, the first flight of the designated as T 47-8 Prototypes In 1961 was.

In the development of the Su- 11, the delta wing, the tail and the cigar-shaped hull were adopted by the Su -9. A key distinguishing feature of the previous model is the extended nose of the aircraft, it served to accommodate the more powerful Oriol radar ( NATO reporting name: Skip spinning ) and only two external load carriers. It has further increased the Ljulka incorporated AL -1 -7F jet engine 98 kN and improved afterburner. The new engine brought despite the higher weight of the aircraft better climb rate and improved performance at high altitude compared to the Su- ninth

The armament of the Su -11 consisted of a pair of air - to-air missiles of the type R -98 ( AA -3 Anab ), who bore the complex designation K- 8, which is mostly of a radar-guided R- 98MR and an infrared- guided R- 98MT composed. How many interceptors that time also had the Su- 11 had no cannon.

The production of the Su -11 began in 1962 under the code name " product 36 ", the delivered series machines were designated Su -11 -8M (because of the armament with K -8M missiles ). The first production aircraft were delivered in June 1962 and completed the work on testing in August. The crash of a machine during the troop testing prompted the Soviet Air Force leadership, which faced the pattern of refusing to stop the entire program for the Yak- 28P. Agreement was finally reached a compromise on a limited production of the Su -11 after appropriate modifications. 1963/64, carried out extensive testing and again in May 1964, the first Su -11 officially put into service. Early 1965, the last of a total of 108 aircraft built was delivered, a significantly smaller number than the previous model Su- ninth In the design office, even the Su -11 was also evaluated in time as a dead end development and T-5 and T -58 worked from 1960 on new designs T -49, which eventually led to the Su -15. The Su- 11 were soon supplemented or replaced by Su -15, but remained partly by the end of the seventies, in the service of air defense regiments.
