Two crew members of the USS New Orleans, an amphibious warship anchored near White Beach Naval Facility, were slightly injured in the fire.
The fire broke out at approximately 4 p.m. on Wednesday and was declared extinguished at 4 a.m. Thursday, the 7th Fleet said. The cause of the fire is currently under investigation, it said.
Okinawa Governor Denny Tamaki urged the US military to take measures to prevent a recurrence.
"The fire is extremely regrettable because it caused great fear to the Okinawa people and threatened to become a disaster that could have harmed residents," Tamaki said at a press conference.
