Surface-to-Air Missiles

Chaparral Missile
ATK manufactures the rocket motor for the Chaparral surface-to-air missile system under a contract from Madison Research Corporation. The Chaparral missile system was originally developed for the U.S. Army National Guard as a short-range, low-altitude air defense system for point defense against direct air attack. It is a heat-seeking weapon used primarily to defeat rotary-wing aircraft and low-flying fixed wing jets by homing in on the aircraft's engine exhaust.

Evolved SeaSparrow
The Evolved SeaSparrow Missile (ESSM) uses a larger rocket motor and tail control system to provide the speed, range, and maneuverability required to intercept an anti-ship missile. The rocket motor incorporates a dual concentric hydroxy-terminated polyether (HTPE) propellant for improved insensitive munitions capability and is the first rocket motor to use a solid-state laser initiation system, designed and developed by ATK. The ESSM motor is co-manufactured by ATK and NAMMO Raufoss of Norway.

The ESSM is an international cooperative upgrade of the RIM-7 NATO SeaSparrow missile. It provides increased battlespace against high-speed, highly maneuverable anti-ship missiles and can be launched from vertical launch systems as well as deck-mounted launch canisters.

Rolling Airframe Missile
The Rolling Airframe Missile (RAM) uses a proven ATK rocket motor developed for the air-to-air AIM-9 missile system. The Mk112 Mod 1 motor used for the RAM is essentially a M 36 Sidewinder motor with minor external case modifications and an electro-mechanical arm fire device installed. The all-boost rocket motor uses a reduced smoke propellant to minimize launch detection.

The RAM Guided Missile Weapon System is one of the world's most modern ship self-defense weapons, designed to provide exceptional protection for ships of all sizes. RAM is a supersonic, lightweight, quick-reaction, fire-and-forget missile system designed to destroy anti-ship missiles as well as other threats. It offers high-firepower capability for engaging multiple threats simultaneously.
