R-27R1 / R-27ER1

R-27R1, R-27ER1 Guided  Missiles 

 

 

The R-27R1 and R-27ER1 medium range air-to-air missiles with semi-active radar homing heads are designed to engage air targets by day and night, in fair and adverse weather conditions, in the front and rear hemispheres, also against diverse underlying surfaces with enemy's active evasive manoeuvring and intensive jamming.
The missiles pursue their targets in accordance with an update proportional navigation method both in the inertial/radio-corrected flight trajectory phase and in the semi-active homing phase after locking on target en route.
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 to arming MiG/Su-type combat aircraft.
The missiles are suspended under the aircraft on the AKU-470 ejection unit/APU-470 launch unit, designed for their carriage, launch and emergency jettison.
The missiles can be adapted for employment from foreign-made carriers in accordance with the technology, developed by the missile designer.
