The Powhatan-class fleet ocean tug USNS Navajo lost its anchor on July 28 during the Rim of the Pacific multinational maritime exercise, according to the U.S. Navy.
It was found on the sandy ocean floor in about 150 feet of water near the Pearl Harbor entrance at an approved training area.
Navy divers from the Mobile Diving Salvage Unit, based at Joint Pearl Harbor-Hickam, assisted the Navajo in recovering the anchor on Aug. 9.
The Navy said one of the mooring lines holding the anchor parted when the 10-inch circumference polyester double braid line chafed in two. The anchor and 90-feet of 2-1/4 inch anchor chain weighed nearly 9,000 pounds.
No injuries were reported.
