worked in close conjunction with the anti-submarine warfare aircraft assigned aboard Carrier Air Wing 11. The Engineering Department underwent a significant change in its propulsion plant during the yard period. The Navy Standard Oil (black oil) fuel system was completely converted to Navy Distillate Fuel. The Air Department added several significant changes to the flight deck, including enlarging the jet blast deflectors (JBD) and installing more powerful catapults to handle the new Grumman F-14 Tomcat, which Kitty Hawk was due to receive for its next deployment. Enlarging JBD#1 meant the No. 1 Aircraft Elevator had to be redesigned, making Kitty Hawk the only carrier at the time having an aircraft elevator that tracked from the hangar deck to the flight deck angling out 6°. Kitty Hawk moved out of dry dock on 28 April 1973, and the next day, on her 12th birthday, she was named a Multi-Purpose Aircraft Carrier (CV). After much-needed upgrades and modifications to Kitty Hawks systems, she departed Hunters Point navy shipyards in San Francisco to begin "sea trial" exercises and then made a short three-day layover in Pearl Harbor for some crew R&R. She then departed for the South China Sea. However, while en route, during routine maintenance to the ship's fuel oil systems in the No. 1 machinery room on 11 December 1973, a flange gasket failed in one of the fuel transfer tubes of JP5 jet fuel that pass through Number 1 engine room. Jet fuel was sprayed, atomized, and ignited, and the ship went to General Quarters for nearly 38 hours. Due to the massive amounts of thick black smoke, the crew was ordered topside to the flight deck until the fire could be controlled and the smoke cleared. Because two and then three of the ship's four propulsion systems had to be shut down during the fire, Kitty Hawk began to list about 7 degrees portside. As a result, many of the aircraft were moved starboard to balance the ship until the fire was finally brought under control and two propulsion systems restored. Kitty Hawk then headed toward the Philippines, where she ported in Subic Bay until the ship's damage could be assessed, and repairs could be made, but there would be three days of waiting before reaching port. Six enlisted sailors died in the fire: FR Michael Deverich, FR Linn Schambers, FR Kevin Johnson, FA Alan Champine, Samuel Cardenas, and
