MIG-27K
Just as the MiG-27 was developed from the MiG-23BM, the MiG-27K was developed from the MiG-23BK (32-26). Its new PrNK-23K nav – attack system could manage the aircraft’s flight path and fire the cannon and missiles simultaneously. Compared with the MiG-23M’s PrNK – 23S, it offered new control possibilities: PMS mode (sighting from a maneuvering aircraft for bomb release as well as cannon and rocket fire) and PKS mode (time-tagged and corrected target tracking and bombing in blind flight according to navigation coordinates).
The twin-barrel 23-mm was also replaced by one GSh-6-30 six-barrel underside cannon. The SUV fire control system had many capabilities: programmed firing, missile and rocket firing (with emergency control), display of weapon availability, bomb release (cluster or individual), and cannon firing. The SUV also warned the pilot of the weapon racks’ release. The aircraft was equipped with a flight management system (with automatic mode transfer), radar warning receiver, active radar jammer, and smoke-emitter. The MiG-27K could cany the same array of weapons as the MiG-23B plus laser-guided missiles. Production took place over several years.
Like the MiG-27, the МЮ-23К could carry four metric tons of external military load |
