The flight of the first prototype took place on February 22, 1975, after a series of tests and utility and engineering references, entering production in 1979.

In 1972, the project was reviewed, and the prototype was completed in 1974 under the name T8-1, with the first flight being made by test pilot Vladimir Ilyushin on February 22, 1975.Sukhoi continued testing with two examples until October 1976, observing the engineering and procedures relating to it.
