M-116 Rolling Airframe Missile (RAM)
Description: The RIM-116 Rolling Airframe Missile (RAM) is a
lightweight quick-reaction, fire-and-forget missile designed to destroy
anti-ship missiles and asymmetric air and surface threats. The RIM-116 RAM
was developed as a joint program between the U.S. and German governments,
and continues to be cooperatively produced and supported. Currently there
are two RIM-116 configurations: Block 0 (RIM-116A) and Block 1 (RIM-116B).
Block 1 is the current production configuration.
Features: The RIM-116 RAM is designed as an all-weather,
high-firepower, low-cost, self-defense system against anti-ship cruise
missiles and other asymmetric threats. Its original Block 0 design was
based on the infrared seeker of the Stinger missile, and the
warhead, rocket motor, and fuse from the Sidewinder
missile. The Block 0 configuration uses Radio Frequency (RF) for midcourse
guidance and transitions to Infrared (IR) guidance for terminal
engagement. There is no shipboard support required (i.e. no illuminators)
after missile launch. While retaining Block 0 guidance modes, Block 1
incorporates the added capability of autonomous IR-all-the-way guidance,
thus countering advanced anti-ship missiles that do not employ onboard
radar seekers. RIM-116 has been installed or is planned on the following
ship classes: CV/CVN, DD-963, FFG, LHA, LHD, LSD, and LPD-17. The Navy
expects to procure approximately 2,000 Block 1 missiles.
Background: The RIM-116 RAM is a joint venture between the U.S.
and German governments. It is currently installed, or planned for
installation, on 78 U.S. Navy and 30 German Navy ships.
