T-3, P.O.Sukhoj

b/w photo from Contest tour VI, Russian Airforce - people and aircraft

Prototype of fighter-interceptor with delta-wing. Project started in 1953, when P.O.Sukhoj OKB was restored after 3 years break. T-3 was developed in parallel with swept-wing S-1 front-line fighter in a record short time, thanks for sharing of technologies and parts between the projects.

T-3 took off on 26 May 1956, with test-pilot V.N.Mahalin at controls. The T-3 had a circular fixed supersonic nose intake with a pointed radome above it for the search radar, and a second spherical radome for the tracking radar in the inlet ('Almaz' system). Swept tailplane was installed on fuselage empennage in the mid position.

Suggested armament consisted of two guided air-to-air missiles K-6 or K-7 (then under development). Flight trials and wind tunnel studies proved that radar housing induces too much drag. Problems and delays with K-6 and K-7 resulted in cancellation of projects, and armament of two early K-5M missiles (the only type in production) was found insufficient. Serious problems were caused by the engine: it was replaced four times during only 38 flight hours!

One prototype assembled, after trials (total 80 hours) re-built into T-43-1 with new radar in redesigned nose section and doubled armament.
