For the collective good of all nations, American command of the earth’s oceans has also provided the bedrock for a globalized economy where 80 percent of the volume and 70 percent of the value of all trade transits safely on the sea.2 But the U.S. Navy has now lost its assured command of the seas — for the frst time in the postWorld War II era — to China in the Western Pacifc. In his confrmation hearings for commander, U.S. Indo-Pacifc Command in 2018, Adm. Philip Davidson stated, “China is now capable of controlling the South China Sea in all scenarios short of war with the United States.” While China may allow the U.S. Navy (or any other navy) to have peacetime access to the South China Sea, Adm. Davidson made clear he can no longer assure such access to protect U.S. interests if a battle were to erupt since “there is no guarantee that the United States would win a future confict with China.”
China’s development of ballistic missiles, such as the DF-21 and DF-26, to target airbases and surface ships (especially aircraft carriers) at ever-longer range means that although U.S. advanced aircraft are peerless in their mission once airborne, they would have no place to land were confict to break out. And China’s constant upgrades in the quieting of diesel and nuclear attack submarines have meant that early warning detection could no longer be done by long-range, passive sonar. It would have to be done by close-in, active sonar instead. The physics of active sonar mean that, in most cases, submarines can only be detected using active sonar after they are already within their weapon-fring range. These threats keep most U.S. forces at a great distance until enough warships (and airlift) have arrived to provide a defensive sanctuary to allow U.S. forces to move forward.
