Raytheon to Provide SeaRAM for Australia’s New Mogami-Class Frigates

Why It Matters

The deal bolsters Australia’s maritime security while expanding Raytheon’s export footprint, reinforcing the US‑Japan‑Australia defense triangle and signaling growing demand for advanced naval missile‑defense solutions.

Key Takeaways

• Raytheon wins SeaRAM contract for Australia's first three frigates
• SeaRAM integrates Phalanx CIWS with RAM missiles for terminal defense
• Deliveries start late 2028; work based in Louisville, Kentucky
• Contract supports Japan's MHI-built Mogadi-class under Sea3000 program
• Australia joins global RAM user community, boosting air‑missile protection

Pulse Analysis

Australia’s Sea3000 program represents a pivotal shift in its naval posture, moving from the legacy Anzac‑class to a modern fleet of 11 Mogami‑class frigates built by Mitsubishi Heavy Industries. By integrating a proven U.S. missile‑defense system, the Royal Australian Navy aims to close the gap in short‑range air and missile protection, a capability increasingly critical as regional threats evolve. The partnership also deepens Australia’s industrial ties with Japan, reflecting a broader trend of allied shipbuilding collaborations in the Indo‑Pacific.

Raytheon’s SeaRAM combines the venerable Phalanx close‑in weapon system with the Rolling Airframe Missile, delivering a compact, autonomous solution that can engage cruise missiles, UAVs and other fast‑moving threats. The system’s track record on U.S. and allied vessels underpins its appeal, and the Louisville‑based contract adds a new export milestone for RTX’s defense portfolio. Revenue from the Sea3000 integration will complement Raytheon’s existing naval contracts, while the late‑2028 delivery timeline aligns with the Australian Navy’s commissioning schedule, ensuring a seamless capability upgrade.

Strategically, the agreement reinforces the trilateral security architecture linking the United States, Japan and Australia. By joining the global RAM user community, Australia not only gains a proven defensive layer but also positions itself for future interoperability and joint training exercises. The deal signals robust demand for next‑generation naval self‑defense kits, prompting other shipbuilders and allied navies to consider similar upgrades as they modernize fleets amid rising maritime competition.
