The uninvited guest: Chinese sub pops up in middle of U.S. Navy exercise, leaving military chiefs red-faced | the Daily Mail: "The lone Chinese vessel slipped past at least a dozen other American warships which were supposed to protect the carrier from hostile aircraft or submarines. And the rest of the costly defensive screen, which usually includes at least two U.S. submarines, was also apparently unable to detect it. According to the Nato source, the encounter has forced a serious re-think of American and Nato naval strategy as commanders reconsider the level of threat from potentially hostile Chinese submarines."
