The SeaRAM is an anti-ship missile defence system against supersonic and subsonic threats including cruise missiles, drones and helicopters. designed and manufactured by Raytheon. The weapon system allows naval vessels to effectively engage high-performance, supersonic and subsonic threats including sea-skimming, anti-ship missiles, high-speed incoming vessels, rotary and fixed-wing aircraft, helicopters and other surface targets. Raytheon delivered an engineering model of the SeaRAM anti-ship missile defence system to the UK’s Royal Navy for suitability testing in 2001. Raytheon and the US Navy conducted test-firing of four blast test vehicles for measuring launch forces of the weapon system in late 2001.
The innovative SeaRAM system is an evolution of the MK15 Phalanx close-in weapon system (CIWS) and and the RAM™ guided weapon system, which entered service in 1980. The SeaRAM system combines the superior accuracy, extended range and high maneuverability of the RAM missile with the high resolution search-and-track sensor and reliable, quick-response capability of the Phalanx Block 1B system. An 11-missile RAM system launcher assembly replaces the Phalanx system’s 20 mm gun. An affordable capability upgrade, the SeaRAM above-deck system fits the exact footprint of the Phalanx system, uses the same power and requires minimal shipboard modification.
The low-risk SeaRAM anti-ship weapon system can be fitted to any class of ship and is designed to offer superior protection for marines and ships. The system is fitted with the same above-deck system and mechanical hardware as Phalanx CIWS and requires minimal shipboard changes. The above-deck system weighs 16,901lb. The SeaRAM close-range protection weapon system is equipped with a latest rolling airframe missile (RAM) guided-missile weapon system. RAM provides superior accuracy, extended range and high manoeuvrability. The SeaRAM self-contained system also employs Phalanx Block 1B CIWS’ high-resolution search and track radar and electro-optical sensor suite, which provides the RAM missile with reliable radio frequency, infrared (IR) detection and tracking capabilities to defeat both air and surface threats.
