The helicopter was operating from the aircraft carrier USS Abraham Lincoln when its rotor hit the flight deck and the aircraft fell into the ocean. One crew member was rescued immediately after the crash.
A search for any other survivors went on for nearly a week before the Navy declared the missing sailors dead.
They were Lt. Bradley A. Foster, 29, a pilot from Oakhurst, California; Lt. Paul R. Fridley, 28, a pilot from Annandale, Virginia; Naval Air Crewman (Helicopter) 2nd Class James P. Buriak, 31, from Salem, Virginia; Hospital Corpsman 2nd Class Sarah F. Burns, 31, from Severna Park, Maryland; and Hospital Corpsman 3rd Class Bailey J. Tucker, 21, from St. Louis, Missouri.
The Navy said the investigation of the crash is continuing.
