Sukhoi Su-11 (Fishpot-C) Interceptor (1964)

Authored By Staff Writer | Last Updated: 4/5/2012

Improvements brought about to the Su-9 Fishpot series of Soviet interceptors gave rise to the Sukhoi Su-11 series.

The Su-11, by any regard, is considered a potent fighter. Based on a further development of the inferior and limited Su-9, the Su-11 featured an improved and more powerful turbojet engine capable of 22,046lbs of thrust with afterburn. Other features deemed as improvements over the base Su-9 were a new radar system, improved weaponry and an elongated nose section for the improved Uragan 5B radar.

The Su-11 had provisions for the newly designed Anab air-to-air missiles. As standard armament fare, the Su-11 would be fitted with just two of this missile type, one was of the infra-red heat-seeking variety and the other of the radar-guided type. Drop tanks became standard when it was realized that the base range of the system was questionable for an interceptor / patrol aircraft of this type.

None of the Su-11 examples saw service outside of the Soviet Union, though the brand continued to serve up until the 1980s. After newer aircraft replaced the Su-11 on the mantle, the system was relegated to becoming a target drone for air defense crew training.

In the end, the full-delta design coupled with a series of advanced air-to-air missile weaponry proved the Su-11 to be quite capable, if unspectacular.
