At 8:30 a.m. local time, officials said there was an explosion that quickly escalated to a three-alarm fire. The San Diego Fire-Rescue Department responded to the fire and assisted base and shipboard firefighting teams.

Navy officials have yet to disclose the cause of the explosion. 

The USS Fitzgerald and USS Russell were also moved away at the height of the fire.
