SeaRAM Close-In Ship Defense System

The SeaRAM Close-In Weapon System is a modern naval point defense weapon designed to protect warships from incoming anti-ship missiles, drones, helicopters, aircraft, and fast attack threats. Developed for the U.S. Navy and allied fleets, SeaRAM combines the proven sensor suite of the Phalanx Close-In Weapon System with the RIM-116 Rolling Airframe Missile launcher, creating a rapid-response defensive shield for naval vessels operating in contested maritime environments.

Manufactured by Raytheon Technologies in partnership with RTX and RAM-System GmbH, SeaRAM was introduced as a lightweight, autonomous solution for ships that require advanced close-in defense without the larger footprint of traditional missile systems.

The system uses an 11-cell launcher armed with RIM-116 missiles capable of intercepting high-speed threats at short range. SeaRAM integrates radar and electro-optical tracking systems from the Phalanx platform, allowing fully autonomous target detection, tracking, and engagement. The missile reaches speeds above Mach 2 and is optimized for defending naval vessels against sea-skimming cruise missiles and unmanned aerial systems.

SeaRAM is currently deployed aboard several U.S. Navy vessels, including Littoral Combat Ships, aircraft carriers, amphibious assault ships, and allied naval platforms worldwide. Its modular design allows rapid installation on existing ships with minimal structural modifications.

Estimated system cost varies depending on configuration and integration requirements, though reports place a single SeaRAM launcher package at approximately USD 25 million to USD 30 million, excluding missile reloads and ship integration costs.
