Rolling Airframe Missile Propulsion System (RAM)

​The RAM-116A Rolling Airframe Missile was cooperatively developed by the United States and Germany as a fire-and-forget counter to incoming anti-ship missiles. The supersonic, lightweight, quick-reaction RAM system is one of the world's most modern ship self-defense weapons, designed to provide exceptional protection for ships of all sizes.

The RAM offers high-firepower capability for engaging multiple threats simultaneously. It is guided initially by the radiation emitted by the seeker of the incoming missile, and in the terminal phase switches over to infrared homing. The RAM first flew in 1978 and was upgraded in 1999 to incorporate a new linear-array infrared seeker.

The Mk112 Mod 1 motor used for RAM is essentially an Mk 36 Sidewinder motor that has minor external case modifications and a electromechanical arm/fire device.

Orbital ATK’s McGregor, Texas, facility developed the RAM motor from 1989 to 1990 and produced the motor until 1993. Production of the RAM rocket motor was transferred to Orbital ATK's Rocket Center, W.Va., facility where production was resumed in 1996. In total, Orbital ATK has manufactured and delivered more than 1,400 reduced-smoke propulsion units to the U.S. Navy.

The features of our propulsion system include radial burn, finocyl propellant grain, an all-boost thrust profile, an electromechanical arm/fire device and a submerged nozzle design. It is the same basic configuration as the Mk 36 propulsion unit for the Sidewinder air-to-air missile.
