SAN DIEGO (AP) — Twenty-one people suffered minor injuries in an explosion and fire Sunday on board a ship at Naval Base San Diego, military officials said.
The blaze was reported shortly before 9 a.m. on USS Bonhomme Richard, said Mike Raney, a spokesman for Naval Surface Force, U.S. Pacific Fleet.
Seventeen sailors and four civilians were hospitalized with “non-life threatening injuries,” Raney said in a brief statement. He didn’t provide additional details.
Previously, officials said at least one person was treated for smoke inhalation.
The cause of the fire was under investigation.
It wasn’t immediately known where on the 840-foot amphibious assault vessel the blast and the fire occurred. The flames sent up a huge plume of dark smoke visible around San Diego.
Rear Adm. Philip Sobeck, commander of Expeditionary Strike Group 3, told the San Diego Union-Tribune that the Navy thinks the fire began somewhere in a lower cargo hold where marine equipment and vehicles are stored.
The fire was not a fueled by fuel oil, hazardous materials or electrical causes, Sobeck told the newspaper. It was fueled by paper, cloth, rags or other materials in a standard fire. He said he is not concerned about the air quality or toxicity around the fire.
There was no ordnance on board, Sobeck said. There are a million gallons of fuel on board, he said, but that is “well below” any heat source.
The explosion was probably caused by a change in air pressure, he told the Union-Tribune.
San Diego is the Bonhomme Richard’s home port, and the ship was undergoing routine maintenance at the time of the fire. About 160 sailors and officers were on board, Raney said — far fewer than the thousand typically on the ship when it’s on active duty.
All crew members were accounted for, said Admiral Mike Gilday, Chief of Naval Operations.
