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 the Phalanx Close-In Weapon System and the Rolling Airframe Missile (RAM) Guided Weapon System.

SeaRAM is designed to extend the inner layer battlespace 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.

The U.S. Navy has used SeaRAM to successfully test-fire the latest variant of the RAM missile, Block 2, and has also completed test firings from an Arleigh Burke-class guided missile destroyer.
