Yakovlev Yak-28

Possessing no more than a configurational similarity to preceding twin-engined Yakovlev combat aircraft, the Yak-129 multi-role aircraft was first flown on 5 March 1958 in tactical attack bomber form. Powered by two Tumansky R-11AF-300 turbojets each rated at 5750kg with afterburning and 3880kg maximum military power, the Yak-129 had a shoulder-mounted wing swept back 63ー inboard of the engine nacelles and 44ー outboard. Although of zero-track arrangement as on the Yak-25 and -27, the undercarriage of the Yak-129 consisted of long-base twin-wheel units sharing aircraft weight almost equally.

Yakovlev Yak-28

Assigned the service designation Yak-28, the first series version of the aircraft was the Yak-28B with an RBR-3 radar bombing system. This was followed by the Yak-28I and -28L tactical attack aircraft, differing in avionic equipment, which were joined under test during 1960 by the Yak-28P dedicated all-weather interceptor fighter. This featured tandem cockpits for the two crew members and was intended for low- and medium-altitude operation with an Orel-D radar and one beam-riding and one radar-homing R-30 (K-8M) AAM. The Yak-28P entered IA-PVO service during the winter of 1961-62.

Progressive upgrading resulted in R-11AF-2-300 engines uprated to 3950kg and 6120kg with afterburning, and enclosed by forward-lengthened nacelles, a longer, sharply-pointed radome housing an upgraded radar and affording lower supersonic drag and reduced erosion, and an additional stores station beneath each wing permitting two short-range dogfight IR missiles to be carried. With all these changes incorporated the designation was changed to Yak-28PM. With further upgrading, the fighter was evaluated as the Yak-28PD, but this suffered high-speed aileron reversal during trials, and by the time that this problem had been overcome production of the Yak-28P was phasing out, terminating in 1967 with limited production of the Yak-28PP electronic warfare version. Production of the fighter totalled 437 aircraft.
