RIM-116 Rolling Airframe Missile
From Biocrawler, the free encyclopedia.
The RIM-116 Rolling Airframe Missile (RAM) is a small, lightweight, infrared homing surface-to-air missile in use by the United States and German Navy. It is intended primarily as a point-defense weapons against anti-ship cruise missiles. There are two variants of RAM (RIM-116A and RIM-116B)which are commonly refered to as RAM BLK 0 and RAM BLK 1 respectively. Both variants use the same fuses, warhead and rocket motor of the AIM-9 Sidewinder. RAM BLK 0 uses the same seeker head as the FIM-92 Stinger. It rolls inflight to provide stability.
The RAM homes in on active radiation emitted from a target, until it picks up an infrared target signature. The onboard Mk 49 launcher installation weighs 5,777 kilograms and stores 21 missiles. This weapon is integrated with the AN/SWY-2 and Ship Self Defense System combat systems.
The RIM-116 was developed by General Dynamics under a July 1976 agreement with Denmark and West Germany. The first 30 were built under FY 85 and became operation on November 14 1992 aboard USS Peleliu (LHA-5). The Navy hopes to purchase 1,600 RAMs and 115 launchers to equip 74 ships. The RIM-116 is currently used on 60 American and German warships. Greece and South Korea have also signed procurement contracts.
