The SeaRAM Anti-Ship Missile Defense System is a sea-based self-defense weapon that protects naval ships from supersonic and subsonic threats.[i] These threats include cruise missiles, drones, and enemy aircraft, as well as small boats. The range of the SeaRAM is currently classified but is estimated to be similar to that of the MK-31 Rolling Airframe Missile (RAM) launching system at 9km.
The SeaRAM is an improved system combining the MK-15 Close-In Weapons System (CIWS) Phalanx and the MK-31 RAM launching system.[ii] The SeaRAM is an 11-launcher system that has the MK-15 CIWS track and search radar and optic sensors.[iii] The defensive platform acts as complete 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.”[iv] This allows the system to engage multiple threats simultaneously without using other weapon systems on the ship.
The United States currently has the SeaRAM installed on multiple Littoral Combat Ships and the USS Porter Arleigh Burke-class destroyer.[v] The U.S. is also in the process of installing SeaRAM on three other Arleigh Burke-class destroyers in Rota, Spain including the USS Donald Cook, the USS Ross and the USS Carney.[vi]
The US Navy needed a way to better protect its four Ballistic Missile Defense (BMD) destroyers stationed in the Mediterranean Sea. Since the ships are so focused upward on searching for missile threats, they become vulnerable themselves to cruise missiles and other incoming munitions. Rather than station another ship nearby to protect the BMD destroyer, Navy engineers realized they could install the SeaRAM anti-ship missile defense system on to the ships to add a layer of protection.[vii]
Also, as drone technology becomes increasing available and deployed, SeaRAM has proven its capability to shoot down incoming drones offering protection that is deployed around the globe and has mobility.
