Ensuring Naval Readiness in the 21st Century: A Call to Action
From Americans for a Stronger Navy

In today’s rapidly changing world, America’s naval forces face unprecedented challenges. Global powers are racing to modernize their fleets and develop advanced weapons systems, while the U.S. Navy must continue to uphold its long-standing mission: to defend freedom of the seas and protect American interests around the globe.

As supporters of a strong and capable Navy, we at Americans for a Stronger Navy understand that maintaining naval superiority requires not only cutting-edge technology but also the operational readiness of our fleet. One critical area that has seen major advancements is how our warships sustain themselves in combat.

The Importance of Staying in the Fight

For decades, the need to leave the battle zone to resupply or rearm has created a tactical challenge for the U.S. Navy. Every moment a ship spends away from the fight is a moment when our forces are vulnerable, and our operational effectiveness is compromised. As the former Chief of Naval Operations, Adm. Arleigh Burke, once said, “All time spent in replenishing was time lost in combat.”

That sentiment rings true today. The pace of modern warfare has only accelerated, and our Navy must keep pace. In the event of a conflict, especially with global adversaries like China, there may be little time to spare. That’s why rearming and resupplying at sea is no longer just an operational convenience—it’s a strategic necessity.

A Breakthrough in Naval Replenishment: TRAM

Enter the Transferrable Rearming Mechanism (TRAM)—a revolutionary new technology that allows ships to reload their vertical launch systems (VLS) at sea. This innovation, which was recently tested aboard the USS Chosin (CG 65), could dramatically enhance the Navy’s ability to sustain long-range combat operations.

“This is a long-sought breakthrough by our Navy that will be an enormous boost to our ability to endure and conduct successive strikes on the battlefield.” – Captain Dave Lennon, USNR (Ret).

Developed by the engineers at Naval Surface Warfare Center in Port Hueneme, California, TRAM enables cruisers, destroyers, and eventually frigates to resupply their missile systems without leaving the theater of operations. This capability allows our warfighters to stay in the fight longer, delivering sustained firepower where and when it’s needed most.

Why This Matters for America’s Future

In a potential conflict, the ability to rapidly resupply and rearm could be a game-changer. Studies have shown that in a high-intensity conflict with a near-peer adversary, the Navy could expend thousands of missiles in a matter of weeks. Traditionally, U.S. warships would need to sail back to a friendly port—potentially hundreds of miles away—to reload, costing valuable time.

TRAM changes that. By allowing the U.S. Navy to resupply its warships while still at sea, we not only save time but also maintain the operational tempo necessary to overwhelm our adversaries. This kind of forward-thinking innovation is precisely what will ensure that our Navy remains the world’s dominant maritime force.

Our Commitment to a Stronger Navy

At Americans for a Stronger Navy, we believe that our country’s naval strength is foundational to our security. Innovations like TRAM represent the future of naval warfare, but they are just one piece of the larger puzzle. Continued investment in technology, training, and shipbuilding is essential to maintaining our edge in an increasingly competitive global arena.

We encourage all Americans to stay informed about the challenges facing our Navy and the solutions that are being developed to meet those challenges. It is through understanding and advocacy that we can ensure our Navy remains ready to protect and defend—both today and in the years to come.

Stay tuned for our next post, where we’ll dive deeper into the technical aspects of TRAM and how it promises to revolutionize naval operations.

Revolutionizing Naval Operations: The Successful Test of the U.S. Navy’s Transferrable Rearming Mechanism (TRAM)

Introduction

In a significant advancement for naval warfare and logistics, the U.S. Navy has successfully completed the first ground-based test of its Transferrable Rearming Mechanism, (TRAM) which will enable U.S. Navy surface combatants to reload missile canisters into their Vertical Launch Systems (VLS) at sea using time-proven underway replenishment (UNREP). Conducted at the Naval Surface Warfare Center Port Hueneme Division, this test marks a pivotal moment in the Navy’s ongoing efforts to enhance its operational flexibility and readiness.

A Long-Awaited Breakthrough

The concept of reloading Vertical Launching System (VLS) cells while underway has been a priority for the Navy for over two decades. In 2023, Secretary of the Navy Carlos Del Toro highlighted the importance of this capability during his speech at the American Society of Naval Engineers Combat Systems Symposium. He emphasized that TRAM is the most viable solution to achieve this critical functionality.

Historically, the Navy relied on strike-down cranes installed on Ticonderoga-class cruisers and early Arleigh Burke-class destroyers. However, these cranes proved impractical and hazardous due to the challenges posed by relative motion at sea. TRAM addresses these issues, promising to revolutionize how the Navy replenishes its missile stocks while on deployment.

Enhancing Operational Flexibility

Rich Hadley, Director of the NSWC Port Hueneme Underway Replenishment Division, praised TRAM’s potential: “By solving key relative motion challenges, TRAM is a capability enabling reloading operations while underway in significant sea states. TRAM will greatly expand the fleet’s logistical flexibility, resilience, as well as volume and tempo of long-range fires.”

Traditionally, VLS reloading required warships to return to port, a process that could sideline vessels for extended periods. Given the evolving strategic landscape and the increasing importance of maintaining a constant naval presence, the ability to reload missiles at sea is more crucial than ever. This capability is especially significant in the context of great power competition in regions like the Indo-Pacific.

A Step Forward in Surface Warfare

The test, conducted with sailors from the Naval Expeditionary Logistics Support Group and USS Chosin (CG 65), demonstrated the practical application of TRAM. The system involves transferring missile canisters from a supply vessel to a warship using a crane, allowing ships to reload in a manner similar to refueling at sea. This method ensures the missile canisters are securely handled during the process, addressing safety concerns associated with the old strike-down cranes.

Steve Brock, Senior Advisor to the Secretary of the Navy, underscored the importance of this advancement: “This demonstration that you superbly delivered on the Secretary’s aggressive timeline sends a powerful message. This revolution in surface warfare will make our existing fleet even more formidable, both in sustained forward presence and lethality—and will create a powerful new near-term deterrent that will disrupt the strategic calculus of our adversaries.”

Looking Ahead

While the specifics of TRAM’s design remain under wraps, the success of the ground-based test at NSWC Port Hueneme sets the stage for its upcoming at-sea trial, scheduled for this fall. The data collected from this initial test will be instrumental in refining the system for operational use.

As the Navy continues to innovate and adapt to the demands of modern naval warfare, TRAM represents a significant leap forward in maintaining a ready and resilient fleet. By enabling ships to reload missiles while underway, the Navy not only enhances its operational capabilities but also sends a clear message of its commitment to maintaining maritime superiority in an increasingly complex global environment.

Stay tuned for further updates as the U.S. Navy prepares for the next phase of TRAM testing and moves closer to integrating this groundbreaking capability into its fleet operations.
