18 People Injured in Fire Aboard Ship at Naval Base San Diego

Eighteen 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. (noon Eastern Time) on USS Bonhomme Richard, said Mike Raney, a spokesman for Naval Surface Force, US Pacific Fleet.

Eighteen people were hospitalized with “non-life threatening injuries,” Raney said in a brief statement. He didn’t have additional details.

Previously officials said at least one person was treated for smoke inhalation.

The cause of the fire was under investigation.

The flames sent up a huge plume of dark smoke visible around San Diego.

San Diego is the Bonhomme Richard’s home port and it 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.

The ship has the capacity to deploy and land helicopters, smaller boats and amphibious vehicles.
