The AA-13 ARROW (R-37M)  is a very long range, air-to-air, active radar-guided missile.  It is a high supersonic solid fuel rocket. The AA-13 is designed to attack large ISR and IW/EW platforms such as the E-3, E-8 JSTARS, RC-135V/W Rivet Joint, EC-130 Compass Call and EC-130 Commando Solo at long ranges. It uses inertial guidance with mid-course updates, and semi-active and active radar homing for the terminal phase. The AA-13 uses large midbody strakes for enhanced lift. In 1994 a trial round killed a target at 162 NMI, a record for a BVR missile.
