SeaRAM Close-In Weapon System (CIWS) Anti-Ship Missile Defense System

SeaRAM is a Mark 15 CIWS variant which integrates two fleet proven weapon systems: The Block 1B Phalanx CIWS and the Rolling Airframe Missile (RAM) guided missile weapon system. SeaRAM combines the Phalanx CIWS Block 1B search-and-track radar and electro optic sensor, along with its inherent threat evaluation and weapon designation capability, with a RAM 11-round launcher guide 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 ASM and high speed aircraft threats in an extended self-defense battle space envelope around the ship. SeaRAM can also be integrated into ship combat control systems to provide additional sensor and fire-control support to other installed ship weapon systems.
