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:
“For I choose that my remembrances of him should be pleasing, affecting, religious. I will love him as a glorified friend, after the free way of friendship, and not pay him a stiff sign of respect, as men do to those whom they fear. A passage read from his discourses, a moving provocation to works like his, any act or meeting which tends to awaken a pure thought, a flow of love, an original design of virtue, I call a worthy, a true commemoration.”
—Ralph Waldo Emerson (1803–1882)
“This was the Eastham famous of late years for its camp- meetings, held in a grove near by, to which thousands flock from all parts of the Bay. We conjectured that the reason for the perhaps unusual, if not unhealthful development of the religious sentiment here, was the fact that a large portion of the population are women whose husbands and sons are either abroad on the sea, or else drowned, and there is nobody but they and the ministers left behind.”
—Henry David Thoreau (1817–1862)
