Sukhoi Su-9

https://en.wikipedia.org/wiki/Sukhoi_Su-9

The Sukhoi Su-9 (NATO reporting name: Fishpot) was a single-engine, all-weather,
missile-armed interceptor aircraft developed by the Soviet Union.

The Su-9 emerged from aerodynamic studies by TsAGI, the Soviet aerodynamic
center, during the Korean War, which devised several optimum aerodynamic
configurations for jet fighters. The design first flew in 1956 as the T-405
prototype. The Su-9 was developed at the same time as the Su-7 'Fitter', and
both were first seen by the West at the Tushino Aviation Day on 24 June 1956,
where the Su-9 was dubbed Fitter-B. It entered service in 1959.

Total production of the Su-9 was about 1,100 aircraft. It is believed that at
least some Su-9s were upgraded to Su-11 'Fishpot-C' form. None were exported to
any of the USSR's client states nor to the Warsaw Pact nations. Remaining Su-9s
and later Su-11s were retired during the 1970s. Some were retained as test
vehicles or converted to remote-piloted vehicles for use as unmanned aerial
vehicles. It was replaced by the upgraded Su-11 and the much-superior Su-15
'Flagon' and MiG-25 'Foxbat'.

The combat record of the 'Fishpot,' if any, is unknown. It is possible that it
was involved in the interception (or even shoot-down) of reconnaissance missions
whose details remain classified, but nothing is publicly admitted.

Role Interceptor and heavy fighter
Manufacturer Sukhoi
First flight 24 June 1956
Introduction 1959
Retired 1970s

The Su-9's fuselage and tail surfaces resembled those of the Su-7, but unlike
the swept wing of that aircraft, the 'Fishpot' used a 53° delta wing with
conventional slab tailplanes. It shared Sukhoi features like the rear-fuselage
air brakes as well as the Su-7's Lyulka AL-7 turbojet engine and nose intake.
