SUKHOI SU 9 SERIES

The quickest way of getting a supersonic interceptor into service was to mate a developed T-3 airframe with the R1L Spin Scan radar and the AA-1 Alkali (K-5M) missile. The Su-9 was developed from the mid-1950s T-3 tailed-delta prototype, a design evaluated against the swept-wing S-1 later adopted for service as the Su-7. Many of the Su-9 single-seaters have been converted into drones and extended in missile firings, but the Su-9U two-seat trainer was retained in service for conversion training of pilots assigned to the dwindling number of Su-11 units.Д«elow: The Su-9В’s ruggedness fits it for harsh operating conditions.ДЄbove: Ten tones of thrust help an Su-11 get airborne. As a front-line fighter it has largely been replaced by the newer Su-15, which retains the several common parts.
