R-27P1 / R-27EP1

    The R-27P1 and R-27EP1 unified medium-range air-to-air missiles with passive radar homing heads are intended for round-the-clock engagement of radio-emitting air targets in fair and adverse weather conditions, in the front hemisphere, against diverse underlying backgrounds and in cases when the enemy targets protect their aircraft with anti-radar active jamming.
    Both missiles are intended for arming MiG/Su-type combat aircraft. They feature “fire-and-forget” covert attack capability.
    The R-27P1 missile is powered with a fixed-thrust solid-fuel engine, the R-27EP1 – with a dual-thrust solid-fuel engine. The fusing system includes a radar fuse and an impact target sensor. The warhead is of a load-carrying rod type. The missile layouts are characterized by modular design.
