R-27T1 / R-27ET1

R-27T1, R-27ET1 Guided Missiles

 

 

The R-27T1 and R-27ET1 medium-range air-to-air missiles with IR homing heads are designed to engage various air targets, such as highly manoeuvrable aircraft, helicopters and the like, in the front and rear hemispheres, by day and night, in spite of natural and organazed jamming, in compliance with the "fire-and-forget" principle.
The missile guidance system employs an updated proportional navigation method with the target lock-on accomplished on the suspension under the carrier.
The missiles' fusing systems are based on radar proximity and impact target sensors.
The missile layouts are characterized by modular design.
Both missiles are intended for aiming MiG/Su-type combat aircraft.
Developed by the Vympel State Machine-building Design Bureau named after I.I. Toropov, JSC.
The missiles are suspended under the aircraft on the APU-470 launch unit, designed for their power supply, combat launch and emergency jettison.
The missiles can also be adapted for employment from foreign-made carriers in accordance with the technology developed by the missile designer.
