United States Navy
The United States Navy is undergoing its largest fleet expansion since the Cold War, driven by a strategic pivot to the Indo-Pacific and the imperative to counter China's growing maritime power. This involves significant investments in shipbuilding, particularly submarines and unmanned systems, alongside a focus on advanced technologies like directed energy weapons. Despite these modernization efforts, the Navy faces challenges including shipbuilding delays, workforce attrition, and maintaining readiness amidst global deployments and increased operational tempo.
