The R-27 medium-range missile is a component of the MiG-29 armament. In its overall characteristics the R-27R is generally comparable to the the American AIM-7M Sparrow missile, which it is said to surpasse it in certain combat capabilities. The R-27 is designed according to a modular principle and is the base for a family of missiles equipped with various types of homing heads and propulsion systems. Several versions of this missile have been produced in Russia with infrared, semi-active and active radar guidance. The AA-10 Alamo-C has a range of 130 km, while other variants have a maximum range of between 70 to 170 kilometers.
The R-27 standardized medium-range guided missile became operational in 1985, intended for MiG-29 and Su-27 frontal aviation fighters. The R-27 is capable of engaging manned and unmanned targets in long-range and close maneuverable air-to-air combat. It can be employed both in individual as well as group operations of platform aircraft. It supports the intercept of targets moving from different directions against the background of the earth's and water's surface in any weather conditions.

The R-27R is equipped with a semiactive radar homing head. The R-27R is equipped with an active radar proximity fuze and impact fuze and a continuous-rod warhead. It is guided to the target by a combination method according to the proportional navigation method: inertially with radiocorrection of trajectory in the initial flight phase, and homing in the terminal phase. This provides for reliable target lock-on at long ranges from the launching aircraft. The missile can be guided along special trajectories to create favorable conditions for homing head and proximity fuze operation. It is capable of going around a plume of passive jamming, of being moved out of the main lobe of the platform's radar, and of approaching a low-flying target from above at a given angle.

The missile has a canard aerodynamic configuration with an axially symmetric cruciform arrangement of aerodynamic surfaces. Control surfaces of original (so-called "butterfly") configuration permit using the same surfaces both for missile yaw and pitch control as well as for its roll stabilization. Each of the four control surfaces has an independent hydraulic drive with a pump-accumulator system for supplying pressure fluid. Canard surfaces are mounted ahead of them. Changing their size ensures identical balance characteristics of the missile when the homing head is replaced.

The R-27T1 and R-27ET1 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 updated 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 for arming MiG/Su-type combat aircraft.
