MIG-27 is a variation of the MIG-23C optimized for the ground attack role. With a new nose, simpler engine intakes and nozzle. These limit supersonic performance, but reduce cost, weight and fuel consumption.
MIG-27 use a 11500kg thrust Tumanski R-29-300. The fire-control radar of MIG-23`s is replaced by IRST and optical equipment In the smaller nose of MIG-27. The pilot is protected well by added armor in the cockpit and the armor windscreen. One Soyuz/Khachaturov R-29B-300 turbojet, rated at 78.40 kN (17625 lb st) dry and 112.7 kN (25335 lb st) with max afterburning; fixed air intakes and two-position (on/off) afterburner nozzle consistent with primary requirement of transonic speed at low altitude; internal fuel capacity 5400 litres (1426 US gallons; 1188 Imp gallons); provision for up to three 790 litre (209 US gallon; 174 Imp gallon) external tanks.
Armament of MIG-27 contains one 23mm or 1*g30mm GSh-30-6(9A621) gun and 4000kg carried pay load. With these changes, MIG-27 fits the ground attack mission quite well.
