Naval Surface Warfare Center, Port Hueneme Division (NSWC PHD) successfully conducted the first land-based demonstration of the Transferrable Rearming Mechanism (TRAM), which will enable U.S. Navy surface combatants to reload missile canisters into their MK 41 Vertical Launching Systems (VLS) at sea.

Secretary of the Navy Carlos Del Toro has made TRAM one of his top priorities. In a speech at Columbia University in New York City in December 2022, the secretary set out the goal that, “during my tenure, we will set the Navy on track to deliver the game-changing capability to rearm our warships at sea. Being able to quickly rearm our warships’ vertical launch tubes at sea will significantly increase forward, persistent combat power with the current force. No longer will our combatants need to withdraw from combat for extended periods to return for vulnerable in-port reloading of weapon systems…. My intention is to perfect this capability and field it for sustained, persistent forward-strike capacity during wartime.”

The Naval Sea Systems Command (NAVSEA) and NSWC PHD team delivered on the secretary’s call for speed at the Sea-Air-Space Exposition in National Harbor, Maryland, in April, where Del Toro said, “The at-sea demonstration will take place later this year — an unheard-of pace for a capability with such revolutionary strategic potential. If we had waited to Program Objective Memorandum, or POM, for it, we wouldn’t see it demonstrated for at least another two or three years. Instead, we’re on track to begin fielding it in two or three years.”
