General William Westmoreland, commanding Military Assistance Command, Vietnam, visited "Ranger" on 9 March 1965 to confer with Rear Admiral Miller. "Ranger" continued air strikes on enemy targets inland until 13 April when a fuel line broke, ignited and engulfed her No. 1 main machinery room in flames. The fire was extinguished in little over an hour. There was one fatality. She put into Subic Bay 15 April and sailed on the 20th for Alameda, arriving home on 6 May. She entered the San Francisco Naval Shipyard 13 May and remained there under overhaul until 30 September 1965.
