The future of America’s long-running dominance of the seas is under threat. The Department of Defense reported recently that the Chinese navy is continuing to modernize at a rapid clip. It is adding guided missile destroyers and nuclear and diesel-electric attack submarines to its fleet, and is developing over-the-horizon radars and next-generation anti-ship cruise missiles, and possibly even the first ever anti-ship ballistic missile. Not only have Chinese ships recently harassed unarmed U.S. naval vessels in the South China Sea, but according to reports emanating from Japan, China will likely complete construction on two conventional aircraft carriers by 2015, and will begin construction on two more nuclear carriers in 2020.
