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.
