The US Navy lost two sailors at sea that are now presumed dead after both fell overboard from their ships last week.

On June 6, Fire Controlman 2nd Class Christopher Clavin fell from the USS Normandy into the water about 80 miles off the coast of North Carolina during a training exercise. Two days later, another sailor who has not yet been identified fell from the USS Shiloh into waters roughly 180 miles east of Okinawa, Japan.

In both cases, the service immediately launched search-and-rescue efforts involving a number of ships, helicopters, fixed-wing aircraft, and Coast Guard vessels. After approximately three days, both searches were called off.

Personnel searching for Clavin covered an area spanning 6,300 square miles, while US and Japanese personnel searched 5,500 square miles for the missing Shiloh sailor.
