Raytheon wins contract modification for MK-31 RAM GMWS Improvement program

Raytheon Missile Systems is being awarded a contract modification to exercise options for design agent and engineering support services for the Rolling Airframe Missile (RAM) upgraded MK-31 Guided Missile Weapon System Improvement program.

The cost-plus-fixed-fee contract modification, worth around $22.5 million, was awarded by the U.S. Naval Sea Systems Command (NAVSEA) located in Washington, DC. Fiscal 2018 weapons procurement (U.S. Navy); German foreign military sales (FMS); Egyptian FMS; and Qatar FMS funding in the amount of around $4.6 million will be obligated at time of award and will not expire at the end of the current fiscal year.

The MK-31 Rolling Airframe Missile (RAM) Guided Missile Weapon System is a cooperative development and production program conducted jointly by the U.S. and the Federal Republic of Germany under memoranda of understanding.

The support procured under contract is required to maintain current weapon system capability as well as resolve issues through design, systems, software maintenance, reliability, maintainability, quality assurance and logistics engineering services.

Work will be performed in Tucson, Arizona (99 percent); and Louisville, Kentucky (1 percent), and is expected to be completed by September 2019.

RIM-116 Rolling Airframe Missile (RAM)

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 (ASCM). 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 certain Arleigh Burke-class destroyers.
