The Su-7BKL was an upgrade over the Su-7B variant. It required less runway for takeoff and landings in both paved and dirt. The aircraft featured rocket boosters to decrease the amount of time required to takeoff, reducing the distance to 800 m, which was considerably less than the 1,250 m of the Su-7B. It also had an improved landing chute and a stronger rear landing gear. The Su-7BKL was produced in large numbers, with a total of 700 units built, making it the most produced variant of the Su-7 design. It was produced up to 1971 when it was replaced by the Su-17. It also received an export variant, the Su-7BMK, produced until 1965 for countries outside the Warsaw pact.

Introduced in Update "Raining Fire", the Su-7BKL is an excellent fighter bomber thanks to its amazing speed and variety of ground ordnance. With very good acceleration at low speeds, a powerful engine, and good top speed, it is often one of the first to reach the battlefield. It has enough ordnance to destroy a full base without affecting its flight performance too much, using 4 x ZB-360 bombs. It also has a ballistic computer for rockets, so in ground Realistic battles it can use the S-24 rockets to destroy any ground target with a single precise shot. However, the Su-7BKL, while very good, suffers from lack of air-to-air missiles or countermeasures, so it has no way to avoid common missiles like the AIM-9G, AIM-9L, or R-60, except for executing very precise evasive manoeuvres. Thus, staying fast and out of the range of planes carrying those weapons is something very important to keep in mind.
