Identify a core capability of the US Navy (USN) among the following options?

Power projection is a core capability of the U.S. Navy, emphasizing its role in deploying military forces and resources to achieve strategic objectives across the globe. This capability allows the Navy to extend its influence, deter adversaries, and provide support in various operations, often without needing to establish a military base in the vicinity. It encompasses not just the ability to project naval power but also integrates air and ground components through amphibious operations, making it vital for modern warfare.

In contrast, ground warfare and joint infantry operations are primarily associated with the U.S. Army and marines, focusing on land-based military engagements. Air superiority, while also important, is more specifically related to the Air Force and involves gaining and maintaining control of the airspace necessary for successful ground and naval operations. Power projection bridges naval capabilities with broader strategic military objectives, making it essential to the overall mission of the U.S. Navy.
