The RIM-116 Rolling Airframe Missile (RAM) is a small, lightweight, infrared homing surface-to-air missile in use by the American, German, Japanese, Greek, Turkish, South Korean, Saudi Arabian, 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 as of 2005 the only U.S. Navy missile to operate in this manner.

The Rolling Airframe Missiles, together with the Mk 49 Guided Missile Launching System (GMLS) and support equipment, make up the RAM Mk 31 Guided Missile Weapon System (GMWS). The Mk-144 Guided Missile Launcher (GML) unit weighs 5,777 kilograms (12,736 lb) and stores 21 missiles. The original weapon cannot employ its own sensors prior to firing so it must be integrated with a ship's combat system, which directs the launcher at targets. On American ships it is integrated with the AN/SWY-2 Ship Defense Surface Missile System (SDSMS) and Ship Self Defense System (SSDS) Mk 1 or Mk 2 based combat systems. SeaRAM, a RAM launcher variant equipped with independent sensors derived from the Vulcan Phalanx CIWS, is being installed on Littoral Combat Ships and Arleigh Burke-class destroyers.
