(CNN) -- One person was missing after a Navy helicopter carrying a crew of five made an emergency water landing off Virginia Beach during a routine training operation, the Navy said Wednesday.
The four rescued crew members of the MH-53E Sea Dragon were taken to a hospital; their injuries were not immediately known, the Navy said in a statement.
None of the crew has been identified.
The Coast Guard cutter Shearwater and two MH-60S helicopters were conducting a search-and-rescue effort near Fort Story for the missing person.
The air temperature was 28 degrees and the water temperature was 41 degrees, with one- to two-foot seas, said U.S. Coast Guard spokesman Nyx Cangemi.
The helicopter was assigned to Helicopter Mine Countermeasures Squadron Fourteen (HM-14), which is based at Naval Station Norfolk Chambers Field.
The MH-53E Sea Dragon carries no weapons. It has two pilots and a crew of one to six airmen, depending on its mission, according to the Navy. There are 31 of the aircraft in operation, it said.
