SeaRAM is an Mk-15 CIWS variant consisting of the combination of two fleet proven weapon systems: the Block 1B Phalanx and the RIM-116 Rolling Airframe Missile (RAM) Guided Missile Weapon System. SeaRAM combines the Phalanx Block 1B search-and-track radar and Electro-Optic sensors, along with its inherent threat evaluation and weapon designation capability, with an 11-round Rolling Airframe Missile launcher assembly on a single mount. The SeaRAM CIWS is a complete combat weapon system that automatically detects, evaluates, tracks, engages, and performs kill assessment against Anti-ship missiles and high speed aircraft threats in an extended self defense battle space envelope around the ship.
