Su-9/11 FISHPOT
The Su-9 was the Su-7's interceptor counterpart, serving exclusively with the Soviet PVO (air defence force). The tailed delta Su-9 was generally similar in configuration to the MiG-21, though larger and heavier. This aircraft was never exported outside the Soviet Union, and saw active duty for only a brief period before other aircraft developments moved the Su-9 into second line service. The Su-11 all-weather interceptor was a refinement of the Su-9 with a new engine, new radar and improved armament. The Sukhoi FISHPOT was withdrawn from Soviet service around 1980.
The Su-9 FISHPOT should not be confused with the the SU-9(K), which was a Sukhoi re-design the German Me 262, superficially resembling the Me-262 though constituting a practically new design,
