Raytheon, an RTX (NYSE: RTX) business, received a contract from Mitsubishi Heavy Industries to provide SeaRAM ship self-defense systems for Australia's Sea3000 General Purpose Frigate program, according to a company announcement.

The contract supports Australia's plan to replace its decommissioning Anzac-class frigates with 11 Upgraded Mogami-class frigates. This marks Australia's first procurement of the SeaRAM terminal ship defense system.

Under the agreement, Raytheon will supply SeaRAM launchers, Blast Test Vehicles, and technical services for the first three ships being built in Japan by MHI. Work will be performed in Louisville, Kentucky, with deliveries expected to begin in late 2028.

SeaRAM combines the Phalanx Close In Weapon System with the Rolling Airframe Missile to provide autonomous terminal defense against cruise missiles and airborne threats. The system extends defensive reach beyond traditional close-in weapon system ranges.

"By integrating SeaRAM on the Royal Australian Navy's new surface combatants, Australia gains a proven, highly effective terminal air and missile defense layer for its future fleet," said Barbara Borganovi, president of Naval Power at Raytheon.

The selection positions Australia as a new member of the global RAM user community. RTX reported 2025 sales of more than $88 billion and employs over 180,000 people globally.
