OSLO, Norway – The U.S. Navy has called off the search for a miniature unmanned submarine that vanished during tests off Norway a week ago, the Norwegian military said Friday.
The 11-foot-long mini-sub, known as a Battlespace Preparation Autonomous Underwater Vehicle, is programmed before being launched to search for mines and, if necessary, destroy them.
It did not surface as expected while being tested during a military exercise last week off Norway, leading its mother ship, the USS Swift, to break off from maneuvers and launch an extensive search.
“The intensive search is over,” Cmdr. Thom Knustad, a Norwegian military spokesman, said by telephone. He said the Swift was heading into a southern Norway port to join other warships in a weekend visit.
There no immediate comment from the U.S. military.
Since the torpedo-shaped submarine could surface anywhere along the shore, warships, boaters and coastal residents have been asked to keep an eye out for it.
