Maritime Cost Imposition: A New Approach to Great Power War

CIMSEC – The U.S. Navy remains intent on using its high-end platforms for sea denial. To its credit, it is developing the kinds of unmanned systems that are ideally suited for this mission, but only at too slow a pace. To optimize its force structure and accelerate the development of technology, the U.S. Navy should instead commit to a strategy of customized, low-end sea denial coupled with high-end global maritime punishment, and then tailor its doctrine, tactics, and weapons systems to each mission.

Lost in the Small Surface Combatant Wilderness

CIMSEC – The real challenge remains the development of the next-generation surface combatant—a ship with the size, power, and growth margin to accommodate future weapons and sensors. That search has eluded the Navy for decades. The Future Frigate is not that answer. Achieving it will require a clean-sheet design, sustained discipline, and a willingness to align ambition with technical reality. Until then, the frigate program represents not a destination, but a holding action.

A Four Ocean Navy: A Wrong Solution to the Right Problem

CIMSEC – Professor Reveron has identified a genuine strategic problem and proposed a historically grounded solution. His geographic differentiation is the correct starting point for the analysis the nation needs. The problem is that he skips that analysis and proceeds directly to organizational and industrial solutions — giving us the Four-Ocean Navy Act before the strategy that would justify it.

US Reveals New Details Of Their Ukrainian Magura USV

Covert Shores – The U.S. Department of Defence (DoD) has released photos on the official media site DVIDS showing a Ukrainian Magura USV (uncrewed surface vessel) at the Balikatan 2026 exercise in the Philippines in April. The exact model may be the Magura V6 or V7. The photos include the loading of a novel shaped charge warhead which was used in the MARSTRIKE-N live firing component of the exercise.

‘We Made A Mistake We Can’t Ever Fix’: The U.S. Navy’s Seawolf-Class Submarine Shortage Makes Russia And China Smile

1945 – In the early 2000s, I visited the USS Connecticut in dry dock while she was getting repairs, completely out of the water, and the image is locked in my head forever: it was amazing. As of this writing in April 2026, the United States Navy has exactly one Seawolf-class attack submarine ready to go to war. And that submarine — USS Jimmy Carter — was not built to fight the way the other two were. As one former engineer for Electric Boat out in Groton told me years ago: “We made a mistake we can’t ever fix. We should have built more Seawolf-class submarines. We are paying the price and there is no going back.”
