Raytheon, an RTX business, has received a contract from Mitsubishi Heavy Industries to supply SeaRAM ship self-defense systems for Australia’s Sea3000 General Purpose Frigate program. The deal covers the first three of 11 upgraded Mogami-class frigates, which will replace the Royal Australian Navy’s retiring Anzac-class vessels.
Under the agreement, Raytheon will deliver SeaRAM launchers, Blast Test Vehicles, and technical services to aid installation and testing on the ships under construction in Japan by Mitsubishi Heavy Industries. SeaRAM integrates the Phalanx Close-In Weapon System with Rolling Airframe Missiles to offer autonomous terminal defense against cruise missiles, drones, helicopters, and other airborne threats, extending protection beyond traditional close-in ranges.
This procurement introduces SeaRAM to the Australian fleet for the first time. Work will occur in Louisville, Kentucky, with deliveries scheduled to start in late 2028. The first frigate is expected by December 2029. The frigates will also feature a 32-cell vertical launch system, a 127mm main gun, and potential Naval Strike Missile capability.
SeaRAM is already in use on Japan’s 12 Mogami-class frigates and similar 06FFM-class vessels, on which the Australian ships are based.
