The Ilyushin Il-26 was a late 1940s project for a strategic heavy bomber by the Ilyushin Design Bureau.[1][2] There were a variety of alternative engines proposed for the Il-26, including the 3,400 kW (4,500 hp) Shvetsov ASh-2TK piston engine and 4,500 kW (6,000 hp) Yakovlev M-501 diesel engine. The specifications varied according to the number and type of engines proposed.

Clandestine use in the Soviet Afghan war

During the Soviet–Afghan War, Soviet & Afghan warplanes would occasionally cross into Pakistan territory while pursuing Afghan Mujahideen forces. Though in early March 1980, Pakistan Air Force Shenyang F-6s of the No. 15 Squadron on Air Defence Alert reported to have intercepted an Il-26 bomber that had intruded into Pakistani airspace however they weren't given clearance to shoot it down and instead escorted it across the Durand Line back into Afghanistan.[3]

Twice its pilots intercepted the enemy aircraft: first a Russian IL-26 on 1st March 1980, and second two Mig-21s in February 1986. The Squadron was not authorised to shoot, much to the frustration of its pilots.".
