The Navy has a big problem on its hands. Four unmanned vehicles have gone missing somewhere underwater in Virginia.
The unmanned vehicles were being used for explosive ordnance disposal training Sunday at the southern end of the Chesapeake Bay. At some point, the Navy lost communication with four of the 13 vehicles.
The Coast Guard and local officials have joined the Navy search in an area between the Hampton Roads Bridge Channel and the Chesapeake Bay Bridge-Tunnel.
The Navy says the missing vehicles do not pose a hazard.
