HONOLULU (AP) - The Navy says more than 40 ships will be gathering in the Hawaiian Islands this summer for the world's largest naval exercises.
The Rim of the Pacific drills will begin on June 29 and last through Aug. 3.
The Navy hosts the exercises in Hawaii every other year. This is the 23rd time they've been held since 1971.
The U.S. Third Fleet said in a news release Tuesday that six submarines, 42 ships and more than 200 aircraft will play a part.
Some ships and aircraft will run partially on biofuels in a first-of-its-kind demonstration of the Navy's development of alternative energy.
Twenty-five thousand people from 22 nations will participate in the exercises, either directly or as observers.
