The MK54 is the primary Anti-Submarine Warfare weapon used by U.S. Navy surface ships, fixed-wing aircraft, and helicopters. Compatible with over 20 launch platforms, it’s capable of tracking, classifying, and attacking underwater targets.

Portsmouth — accelerating advanced undersea systems

Workers examining document - factory floor

Custom‑built labs replicate undersea conditions – crushing pressures, extreme temperatures and complex acoustic environments – in one controlled setting. Teams can rapidly test, tune and validate systems with greater precision reducing the need for at-sea or off-site testing.

Rigorous testing

The MK54 provides a high-level sonar source, narrow beams to improve performance in contested environments and reliability as proven during in-water exercises. It has undergone over 25,000 high-fidelity simulation runs at the Naval Undersea Warfare Center in Newport, Rhode Island.

Increased performance and effectiveness

Under the current MK54 Mod 2 program, Raytheon is developing new propulsion and warhead technology. These enhancements will increase weapon effectiveness against a wide range of targets and provide the U.S. Navy with an incremental jump in weapon performance.
