SeaRAM Anti-Ship Missile Defense System
The SeaRAM Anti-Ship Missile Defense System provides the highest level of ship self-defense with extended keep-out range capability.
The SeaRAM Anti-Ship Missile Defense System is a spiral development of key attributes of both Phalanx CIWS and the Rolling Airframe Missile (RAM) Guided Weapon System. SeaRAM is designed to extend the inner layer battle space and enable the ship to effectively engage multiple high-performance, supersonic, and subsonic threats.
An 11-missile RAM launcher assembly replaces Phalanx's 20 mm gun. SeaRAM combines RAM's superior accuracy, extended range, and high maneuverability with the Phalanx Block 1B's high resolution search-and-track sensor systems and reliable quick-response capability.
SeaRAM is an affordable capability upgrade -- the above-deck system fits the exact footprint of the Phalanx, uses the same power, and requires minimal shipboard modification.
