Design and Development
It was first seen by the West at the Tushino air show in 1961. Western analysts initially believed it to be a fighter rather than an attack aircraft — and a continuation of the Yak-25M, at that — and it was designated "Flashlight". After its actual role was realized, the Yak-28 bomber series was redesignated "Brewer".
The Yak-28 had a large mid-mounted wing, swept at 45 degrees. The tailplane set halfway up the vertical fin (with cut-outs to allow rudder movement). Slats were fitted on the leading edges and slotted flaps are mounted on the trailing edges of the wings. The two Tumansky R-11 turbojet engines, initially with 57 kN (12,795 lbf) thrust each, were mounted in pods, similar to the previous Yak-25. The wing-mounted engines and bicycle-type main landing gear (supplemented by outrigger wheels in fairings near the wingtips) were widely spaced, allowing most of the fuselage to be used for fuel and equipment. It was primarily subsonic, although Mach 1 could be exceeded at high altitude.
Total production of all Yak-28s was 1,180.

Famous quotes containing the words design and/or development:
“You can make as good a design out of an American turkey as a Japanese out of his native stork.”
—For the State of Illinois, U.S. public relief program (1935-1943)
“The man, or the boy, in his development is psychologically deterred from incorporating serving characteristics by an easily observable fact: there are already people around who are clearly meant to serve and they are girls and women. To perform the activities these people are doing is to risk being, and being thought of, and thinking of oneself, as a woman. This has been made a terrifying prospect and has been made to constitute a major threat to masculine identity.”
—Jean Baker Miller (20th century)
