As an interceptor, typical armament includes four supersonic (M > 5) UR great range R-40T (R-40TD) air-to-air missiles with thermal homing head and R-40P (R-40RD) with semi-active radar guidance system (maximum launch range, on altitudinal goal on a collision course – 35–60 km). A fuel tank can be suspended under the fuselage. The aircraft could carry unguided gravity bombs in a rudimentary strike capability. As the bombs would weigh no more and incur no more drag than its regular load of R-40 missiles, its performance was not impaired, leading to some impressive bombing feats; when released at an altitude of 20,000 m (66,000 ft) and a speed above Mach 2, a 500 kg bomb would have a glide range of several tens of kilometres.
