was detached to assist LST's as they landed marines and equipment on Saipan. On 7 July, she got underway for Eniwetok. Tawasa operated with ServRon 10 from 31 July to 24 August 1944 when she joined ServRon, South Pacific. The ship operated in the South Pacific until 9 May 1946 when she departed Nouméa for the United States. Post-war activity From San Pedro, her home port, she operated along the California coast until returning to Pearl Harbor on 27 December 1946. On 23 February 1947, Tawasa headed for Japan and an eight-month tour at Yokosuka before returning home on 30 October 1947. The tug headed for Alaska on 15 June 1948 and operated out of Adak until October when she steamed to Guam for four months. She then remained on the west coast until 10 August 1950 when she got underway for a five-month tour in Alaska. During the next decade, her operations on the west coast were broken by seven deployments to the Far East for operations with the 7th Fleet. Korean War operations On the first of these deployments, from 4 June 1952 to 1 March 1953, Tawasa operated with task force TF 92, the Logistics Support Force which supplied United Nations forces in Korea. She also performed services at the Korean ports of Cho Do, Sokcho, and Chinhae. Operation Wigwam Tawasa towed a nuclear bomb used as a depth charge as it was detonated in Operation Wigwam in 1955. Wigwam involved a single test of the Mark 90 Betty nuclear bomb, a cold war nuclear depth charge, developed by the United States in 1952. The test was conducted on May 14, 1955, about southwest of San Diego, California, with 6,800 personnel aboard 30 ships involved. The purpose of Wigwam was to determine the vulnerability of submarines to deeply detonated nuclear weapons, and to evaluate the feasibility of using such weapons. The test device was suspended to a depth of by a cable attached to a barge. A tow line connected the 205 ft. Tawasa fleet tug with the shot barge itself. Suspended from the tow lines of other tugs were three miniature unmanned submarines named "Squaws", each packed with cameras and telemetry instruments. The time of detonation was 1300 hrs Pacific Time. The test was carried out without incident, and the device yielded 30 kilotons. Three personnel received doses of over 0.5 rem (5 mSv). Other sailors
