Sukhoi Su-9 / Su-11 Fishpot

Summary

Description

The Su-9 Fishpot was a delta-wing aircraft similar in configuration to the MiG-21, but larger and heavier. Developed from the S-1 prototype of the Su-7, the Su-9 was specialized in all-weather interception and armed with four large air-to-air missiles. It was built on a large scale, likely exceeding 1000 units, and a two-seat training version also existed.

The Su-11 (NATO designation: Fishpot-C) was a development of the Su-9, featuring a new AL-7F-2 engine, a new Skip Spin radar, and modified armament. Generally, it carried a pair of air-to-air missiles, the AA-3 Anab, one radar-guided and the other infrared-guided, following Soviet practice, instead of the original four AA-1 Alkali missiles. It can be distinguished from the Su-9 by its longer nose, wider air intake, and larger radome to accommodate the radar. It was built on a temporary basis while waiting for the Su-15 to enter service. The Fishpot was exclusively used by the Russian Air Force and retired from service around 1980. Western sources estimated that by the late 1970s, it accounted for a quarter of the interceptor aircraft operated by the IA-PVO.

Compared to the MiG-21, the Su-9/11 appeared larger and more powerful but less capable in performance. Nevertheless, they served as the basis for the development of new aircraft from the Sukhoi design bureau, notably the Su-15 Flagon.
