The RAM Block 2 is an upgraded version of the RAM missile aimed at more effectively countering more maneuverable antiship missiles through a four-axis independent control actuator system, increased rocket motor capability, an improved passive radio frequency seeker and upgraded components of the infrared seeker, and advanced kinematics. The Block 0's radar homing capabilities have been retained. The Block 1 (RIM-116B) is an improved version of the RAM missile that adds an overall infrared-only guidance system that enables it to intercept missiles that are not emitting any radar signals. In test firings, the Block 0 missiles achieved hit rates of over 95%. Block 0 missiles were designed to initially home in on radiation emitted from a target (such as the active radar of an incoming antiship missile), switching to an infrared seeker derived from that of the FIM-92 Stinger missile for terminal guidance. The original version of the missile, called Block 0, was based on the AIM-9 Sidewinder air-to-air missile, whose rocket motor, fuze, and warhead were used. The aircraft carrier USS Theodore Roosevelt launches a Rolling Airframe Missile (RAM) Block 0 Ford-class aircraft carriers, Nimitz-class aircraft carriers, Wasp-class amphibious assault ships, America-class amphibious assault ships, San Antonio-class amphibious transport dock ships, Whidbey Island-class dock landing ship, Harpers Ferry-class dock landing ships, and littoral combat ships (LCS). The missile is currently active aboard Gerald R. Navy plans to purchase a total of about 1,600 RAMs and 115 launchers to equip 74 ships.
South Korea has signed license-production contracts for their navy's KDX-II, KDX-III, and Dokdo-class amphibious assault ship. The Greek Navy has equipped the new Super Vita–class fast attack craft with the RAM. All new German Navy warships will be equipped with the RAM, such as the new Braunschweig-class corvettes, which will mount two RAM launchers per ship. The RIM-116 is in service on several American and 30 German warships. The first 30 missiles were built in FY85 and they became operational on 14 November 1992, on board USS Peleliu. The Mk 49 launcher was evaluated on board the destroyer USS David R. Denmark dropped out of the program, but the US Navy joined in as the major partner. The RIM-116 was developed by General Dynamics Pomona and Valley Systems divisions under a July 1976 agreement with Denmark and West Germany (the General Dynamics missile business was later acquired by Hughes Aircraft and is today part of Raytheon). SeaRAM, a launcher variant equipped with independent sensors derived from the Vulcan Phalanx CIWS, is being installed on Littoral Combat Ships and certain Arleigh Burke-class destroyers. 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. 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. The Mk-144 Guided Missile Launcher (GML) unit weighs 5,777 kilograms (12,736 lb) and stores 21 missiles. 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). In addition, because the missile rolls, only one pair of steering canards is required. The rolling interferometer permits the antennas to look at all planes of incoming energy. The missile must roll during flight because the RF tracking system uses a two-antenna interferometer that can measure phase interference of the electromagnetic wave in one plane only. As its name indicates, RAM rolls as it flies. It was intended originally and used primarily as a point-defense weapon against anti-ship missiles. The RIM-116 Rolling Airframe Missile ( RAM) is a small, lightweight, infrared homing surface-to-air missile in use by the German, Japanese, Greek, Turkish, South Korean, Saudi Arabian, Egyptian, Mexican and US Navies.
