India and Russia have signed an agreement on delivering R-27 missiles for the Indian Air Force, ANI news agency reported. The R-27 Missile is a guided medium-range, air-to-air missile which can be integrated with Russian fourth-generation fighters.
“A contract was signed with Russia on delivery of R-27 missiles for Su-30MKI fighter jets in the Indian Air Force,” the news agency quoted a source as saying. The contract is reported to be worth over $200 million. No other details of the deal were reported. Moscow is officially yet to confirm the development.
R-27 Air-To-Air Missiles
The R-27 Missile is a guided medium-range, air-to-air missile which can be integrated on Russian fourth-generation fighters such as the MiG-29, MiG-31, Su-27, Su-30, Su-33, Su-34, Su-35, Su-37 and Yak-141.
The R-27 missile is designed to strike all types of aircraft, rotorcraft, cruise missiles and unmanned aircraft systems. It can engage airborne targets in any weather conditions during day and night.
The R-27 missile is designed to destroy air targets in adverse weather conditions at any time of day. The missile has a length of 4m, a body diameter of 0.23m and wingspan of 0.77m. The weight of the missile is 253kg. The R-27 can be launched from an altitude of 25km, up to a range of 60km. The guidance system of the missile includes semi-active radar seeker with command updates.
The R-27 missile structure includes a cylindrical body and axisymmetric, crosswise arranged surfaces in duck configuration. The modular structure allows the integration of various guidance systems and motors (two options).
All versions of the R-27 missile are equipped with the same 39kg Rod warhead initiated by radar-proximity and impact fuses. The air-to-air missile is designed with a canard aerodynamic configuration. The surfaces control pitch and yaw of the missile while ensuring the roll stabilisation. The maximum operational g-loading of the missile is 8g.
The guidance method of the missile can be converted from semi-active radar homing to infrared by substituting the seeker module. The propulsion system includes a solid-propellant rocket motor.
