U.S. military searching for Marine missing off San Diego coast

Authorities are searching for a U.S. Marine who went missing during a training exercise off the coast of Southern California.

Search and rescue efforts began around 1:20 a.m. Thursday, and after nearly two full days, the Navy transitioned to recovery operations.

The search spanned roughly 2,400 square miles and involved officials from the Navy, Marine Corps, Coast Guard and Air Force who used three surface ships and 12 aircraft.

The Marine was serving on the transport dock ship USS Anchorage and went missing during a training operation involving the 13th Marine Expeditionary Unit and Makin Island Amphibious Ready Group.

The search marks the second time in recent weeks that the U.S. military has searched for missing service members. The Associated Press reported that the remains of two Army soldiers who went missing while off duty from military exercises in Morocco were recovered in May.

Officials did not identify the Marine who went missing Thursday or disclose the circumstances surrounding his disappearance, saying that the name will be withheld until after the family is notified.

“Our thoughts and prayers are with the family and all who are affected during this difficult time,” the Navy said in a news release.
