China militarizing deep-ocean as another domain of warfare by building deep sea Naval base in South China Sea and deep sea “space station.”

Like the British Royal Navy more than a century before it, the U.S. Navy has a command of the sea that affords the United States unrivaled international influence.  By its use of the sea, which covers nearly three-quarters of the earth, a navy can do things that land-based forces cannot. It can provide extraordinary access to points of interest around the globe, patrolling vital waterways and maneuvering to distant shores and population centers. The United States is a maritime superpower because its heavily armed warships can travel thousands of miles in a matter of days and linger around points of interest without imposing on another country’s sovereignty and, if desired, without provoking much attention. This makes the navy an incredibly powerful tool, especially for responding to international crises.
