Raytheon has secured a contract from Mitsubishi Heavy Industries to provide SeaRAM naval self-defense systems for Australia’s upgraded Mogami-class frigates being acquired through the Sea3000 General Purpose Frigate program.
The deal includes the supply of SeaRAM launch systems, blast test vehicles, and engineering support for installation and testing activities on the first three ships. Initial deliveries are scheduled for late 2028.
Australia’s Sea3000 program is designed to replace the ageing Anzac-class frigates that have served with the Royal Australian Navy since the mid-1990s.
Japan has already integrated SeaRAM systems on its operational Mogami-class frigates, while additional 06FFM-class vessels under construction also feature the technology. These Japanese designs form the baseline for Australia’s future frigate fleet.
About SeaRAM
SeaRAM integrates the Phalanx close-in weapon system with the Rolling Airframe Missile platform to deliver automated point-defense protection against airborne threats such as cruise missiles, drones, and helicopters.
Instead of the traditional 20mm Gatling cannon used by the Phalanx system, SeaRAM employs a missile launcher capable of carrying and firing up to 11 RAM missiles. The system combines the missile’s agility and engagement range with the Phalanx Block 1B’s high-precision tracking sensors and fast reaction capability.
Because SeaRAM is designed as a deck-mounted plug-in upgrade, it preserves the same footprint and power requirements as the Phalanx system, enabling straightforward installation with minimal modifications while enhancing naval self-defense effectiveness.
