TOKYO -- Off the coast of Japan's glittering capital, the U.S. Navy recently dropped a hint about its shifting strategy in Asia.
In March, the Navy and the Japan Maritime Self-Defense Force conducted a torpedo drill in Tokyo Bay for the first time. From the air, an MH-60R helicopter launched an inert training torpedo into Japanese waters, simulating an attack on a submarine. Previously, all similar torpedo exercises had been conducted off the shores of San Diego.
