USS Mount Katmai (AE-16) was a Mount Hood-class ammunition ship of the United States Navy, that saw service in the Korean War and the Vietnam War. The ship was laid down on 11 November 1944 by North Carolina Shipbuilding Co., Wilmington, N.C.; launched on 6 January 1945, sponsored by Mrs. A. E. DeMaray; and commissioned on 21 July 1945 at Jacksonville, Florida. Service history Pacific, 1945–1950 After shakedown and fitting out, Mount Katmai reported to Commander Service Force Atlantic Fleet on 8 September 1945. She was then ordered to proceed to Hawaii via the Panama Canal. The ammunition ship was assigned to the western Pacific from there, arriving Leyte in mid-October 1945. Korean War, 1950–1953 Mount Katmai was involved in normal support operation off the Pacific coast when the Korean War began. On 22 July 1950 she deployed from San Francisco to WestPac, arriving in the combat zone on 18 August. She rearmed and replenished combatant ships of TFs 77 and 95 in the Yellow Sea and the Sea of Japan. Returning home in November 1951, she departed again for the Korean war theater in April 1952, again supporting units of TFs 77 and 95. Back in the United States in February 1953, she sailed again for the Far East in May 1953. During this deployment, she rearmed approximately 50 ships before the war ended. WestPac deployments, 1954–1964 Following the armistice, Mount Katmai returned to CONUS for overhaul at Mare Island Naval Shipyard. She got underway for the Far East in May 1954 for a six-month tour, the first of nine WestPac deployments in the following decade, in which she alternated service on the west coast with operations in the Far East. In December 1964 Mount Katmai commenced an extensive overhaul period, including installation of increased communications capabilities and a helicopter deck for vertical replenishment. Vietnam, 1965–1973 On 26 February 1965, the ship departed San Francisco, underway to a new war zone to replenish 7th Fleet ships. She arrived Subic Bay on 15 May via Pearl Harbor. Within a few days, she was underway for rearming operations in the South China Sea, servicing the carrier strike groups and combatant ships off Vietnam. Operating out of Subic, Mount Katmai provided logistical support to the operating forces until late November. She departed Hong Kong on 1 December 1965, arriving San Francisco on 16 December.
