The Su-7BKL was a development of the Su-7B, which required less runway for takeoff and landings. It featured rocket boosters to decrease takeoff time and distance, reducing the distance to 800m. It also had an improved landing chute and a stronger main landing gear. The Su-7BKL was produced in large numbers, making it the most produced variant of the Su-7. Bort 15 red was added to the collection at Monino in December 1975.

This is the rough-field variant of the main production version Su-7B (S-22) and this example is on display at the Central Museum of the Air Forces at Monino.
