MiG-21SIVI / 7//УІ5
The MiG-2 ISM, the continuation of the "Meccano” game started with the Ye-6, evolved from a M1G-21S airframe on which two significant modifications were made. First, the new aircraft was powered by a more powerful turbojet developed by S. Gavrilov: the R-l 3-300, rated at 3,990 daN (4,070 kg st) dry and 6,360 daN (6,490 kg st) with afterburner Second, it was armed with aburlt-in twin-barrel GSh-23L cannon with 200 rounds (the same weapon in a gun pod caused too much drag) The lessons of air battles in the Middle East finally registered, and the concept of a fighter armed only with missiles was flatly abandoned. The new ASP-PFD gunsight was designed specifically for combat situations requiring tight, high-g maneuvers The aircraft was equipped with the RP-22 Sapfir-21 and the SPO-10 radar warning receiver
In addition to the built-in cannon, armament included two K-13T (R-3S) or two K-13R (R-3R) air-to-air missiles, and/or UB-16 and UB-32 rocket pods, S-24 large-caliber rockets, four 100-kg (220-pound) bombs, and napalm containers The total fuel capacity of this variant was reduced to 2,650 1 (700 US gallons) The MiG-21SM was mass-produced for the WS in the Gorki factory between 1968 and 1974.
