Oops is now a naval term

Greg Grant of Defensetech.org writes this:

The Navy lost four submersible unmanned drones over the weekend in the Chesapeake Bay, near Norfolk, Virginia, and is asking the public for help in finding the errant torpedo-shaped drones. Communication was lost with four of the thirteen undersea drones on Sunday as they were scanning the sea floor for mines as part of a training exercise.
The Navy said the search continues, and they are thinking of using dolphins and sealions trained to hunt for mines to aid in the search. The Navy said the undersea drones are not a danger to civilians or the environment, and asked boaters, if they happen to spot one floating on the water, to call the U.S. Second Fleet commander.
