Defense News – China’s recent announcements of new submarine-hunting technologies are probably more hype than hardware, but they highlight Beijing’s goal of countering the threat posed by U.S. attack boats, which remain essential to U.S. war plans. The U.S. submarine force will not be able to rest on its laurels as the world’s finest for much longer. Soon it will need new approaches and capabilities to operate and potentially fight in the bastions that China and Russia consider their home waters.
