SAN DIEGO (AP) — The U.S. Navy charged a sailor Thursday with starting a fire last year that destroyed the USS Bonhomme Richard docked off San Diego, marking the maritime branch’s worst warship blaze outside of combat in recent memory.

The amphibious assault ship burned for more than four days. Left with extensive structural, electrical and mechanical damage, the ship was later scrapped. Estimates to replace it ran up to $4 billion.

The sailor was a member of the crew at the time, Cmdr. Sean Robertson, a U.S. 3rd Fleet spokesperson, said in a statement. The sailor was charged with aggravated arson and the willful hazarding of a vessel, Robertson said. No name was released.

No other details were provided, and it was unclear what evidence was found or what the motive was.

The amphibious assault ships are among the few in the U.S. fleet that can act as mini aircraft carriers.

The Bonhomme Richard had been nearing the end of a two-year upgrade estimated to cost $250 million when the fire broke out on July 12, 2020.

About 160 sailors and officers were on board when the flames sent up a huge plume of dark smoke from the 840-foot (256-meter) vessel, which had been docked at Naval Base San Diego while undergoing the upgrade.

The fire started in the ship’s lower storage area, where cardboard boxes, rags and other maintenance supplies were stored. But winds coming off the San Diego Bay whipped up the flames and the flames spread up the elevator shafts and exhaust stacks.

Then two explosions — one heard as far as 13 miles (21 kilometers) away — caused it to grow even bigger.

The fire sent acrid smoke billowing over San Diego, and officials had recommended people avoid exercising outdoors.

Firefighters attacked the flames inside the ship, while firefighting vessels with water cannons directed streams of seawater into the ship and helicopters made water drops.

More than 60 sailors and civilians were treated for minor injuries, heat exhaustion and smoke inhalation.
