for future action. Kitty Hawk was awarded the Presidential Unit Citation for exceptionally meritorious and heroic service from 23 December 1967 to 1 June 1968, which included the Tet Offensive, while participating in combat operations in Southeast Asia, and the Navy Unit Meritorious Commendation for exceptionally meritorious service from 15 January 1969 to 27 August 1969 while participating in combat operations in Southeast Asia and contingency operations in Northeast Asia. Both awards noted that the officers and men of the Kitty Hawk displayed undaunted spirit, courage, professionalism, and dedication to maintain their ship as a fighting unit under the most arduous operating conditions to enable her pilots to destroy vital military targets in North Vietnam despite intense opposition and extremely adverse weather conditions. While on deployment from November 1967 to June 1968, Kitty Hawk experienced a fire in while in port at Subic Bay and went to general quarters for 51 hours. On 16 January 1968 year, a C-1A Trader swerved off the wet deck. Four personnel aboard were lost along with the aircraft and could not be recovered. After a deployment from November 1968 to June 1969, Kitty Hawk returned to San Diego for a month and then went to Puget Sound shipyard in September 1969 for dry dock. On 12 October 1972 during the Vietnam War, Kitty Hawk was en route to her station in the Gulf of Tonkin when a race riot involving more than 200 sailors broke out. Nearly 50 sailors were injured in this widely publicized incident. This incident resulted in a Congressional inquiry into discipline in the Navy. 1973 to 1977 From January through July 1973, Kitty Hawk changed home ports from San Diego to San Francisco. Kitty Hawk moved into dry dock on 14 January 1973. Work began to convert the ship from an attack (CVA) to a multi-mission carrier (CV). The "CV" designation indicated that Kitty Hawk was no longer strictly an attack carrier, in that anti-submarine warfare would also become a major role. Kitty Hawk became the first Pacific Fleet carrier to carry the multi-purpose "CV" designation. The conversion consisted of adding ten new helicopter calibrating stations, installing sonar/sonobuoy readout and analysis center and associated equipment, and changing a large portion of the ship's operating procedures. One of the significant equipment/space changes in the conversion was the addition of the Anti-Submarine Classification and Analysis Center (ASCAC) in the CIC area. ASCAC
