The RIM-116 Rolling Airframe Missile (RAM) is a small, lightweight, infrared homing surface-to-air missile in use by the American, German, South Korean, Greek, Turkish, Saudi and Egyptian navies. It was intended originally and used primarily as a point-defense weapon against anti-ship cruise missiles. The missile is so-named because it rolls around its longitudinal axis to stabilize its flight path, much like a bullet fired from a rifled barrel. It is the only US Navy Missile to operate in this manner.
