Arson suspected cause of huge fire on Navy ship in San Diego, sailor being questioned

SAN DIEGO, California — Arson is suspected as the cause of a July 12 fire that left extensive damage to the USS Bonhomme Richard and a U.S. Navy sailor is being questioned as a potential suspect, a senior defense official said Wednesday.

The official, with knowledge of the investigation, spoke to The Associated Press on condition of anonymity to provide details not yet made public.

The amphibious assault ship, which was docked in San Diego, burned for more than four days last month and was the Navy’s worst U.S. warship fire outside of combat in recent memory.

The future of the ship remains uncertain.

The amphibious assault ships are among the few in the U.S. fleet that can act as a mini aircraft carrier. If the Bonhomme Richard is not repaired, it could cost the Navy up to $4 billion to replace it, according to defense analysts.
