The production of the YAK-28 frontline jet-powered supersonic
bomber and Us modifications took in total more than 12 years.
The Plant manufactured a wide range of modifications of the
YAK-28 with different types of equipment, the total number of
aircraft built in the bomber, reconnaissance, training and other
versions being about 700 pcs.
The YAK-28 was the first supersonic aircraft whose production
was mastered at the Irkutsk Aircraft Plant. More stringent
requirements for the outer contour precision, for the
construction strength and stiffness to successfully overcome the
sonic barrier — alt these demanded an updating of the aircraft
assembly methods, a change of the flight testing programme.
The YAK-28 aircraft was adopted by the Air Forces of our
country. Some versions of this aircraft are still in operation.
