RIM-116 Rolling Airframe Missile (RAM)

 
Description
The RIM-116 RAM is a lightweight, quick-reaction, fire-and-forget missile designed to destroy anti-ship cruise missiles and asymmetric air and surface threats. The RIM-116 RAM was developed as a cooperative program between the U.S. and German governments, and continues to be cooperatively produced and supported. Currently there are three RIM-116 configurations: Block 0 (RIM-116), Block 1A (RIM-116B) and Block 2 (RIM-116C). Block 0 and Block 1A have completed production. The RAM Block 2 configuration is currently in low rate initial production.
 
Features
The RIM-116 RAM is designed as a high-firepower, low-cost, self-defense system against anti-ship cruise missiles and other asymmetric threats. For all versions of the missile, there is no shipboard support required (i.e., no illuminators) after missile launch. The original Block 0 design was based upon 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. The Block 1A incorporates the added capability of autonomous IR-all-the-way guidance, thus countering advanced anti-ship cruise missiles that do not employ onboard radar seekers.

The Block 2 missile provides kinematic and guidance improvements for countering maneuvering threats and regaining battlespace. It features a control section upgrade (four canards vs. two for Block 1A), a propulsion section upgrade (a larger, composite case rocket motor) and an evolved radio frequency (ERF) receiver. RAM Block 2 initial operating capability (IOC) was achieved in May 2015.
 
Background
The RIM-116 RAM is a cooperative program between the U.S. and German governments. The RIM-116 RAM is fully operational in the U.S., German and allied Navies (including South Korea, Greece, Egypt, UAE, Turkey and Japan) with over 4500 missiles having been produced throughout the life of the program. RAM is deployed worldwide via the Mark 49 RAM guided missile launching system (GMLS) on more than 100 ships ranging from fast patrol boats to aircraft carriers and is being installed on a majority of new USN ship classes (LHA 6, CVN 78 and LCS). The RIM-116 RAM is also deployed on the LCS ship class utilizing Mark 15 Mod 31 SeaRAM close in weapon system (CIWS) and DDG (64/71/75/78) utilizing Mark 15 Mod 33 SeaRAM CIWS.
