Class Notes:
Built to Army Design 228 (tug, ocean going, diesel, steel, 123') under Army contracts dated 1 Oct 1942 (LT 60), 25 Sep 1942 (LT 132), and 28 May 1943 (LT 646). The specifications for Design 228 were dated September 1942 and a total of 31 tugs of this type (LT 57-64, 128-137, 352-358, and 643-648) were ordered between September 1942 and February 1944 and delivered between September 1943 and March 1945. LT 60, 132, and 646 (later T-ATA 241-243) were among Army vessels and service craft in Alaska that MSTS and the Army's Chief of Transportation mutually agreed would be transferred on 1 November 1950 and for which classification and hull numbers were approved on 31 October 1950.

When sufficient personnel became available the three tugs were placed in commission in mid-1951 and assigned to MSTS Kodiak for Bering Sea area resupply operations in Alaska. All three passed to MSTS on 26 October 1951 and were taken out of commission and put in service. Thereafter they were continuously employed. On 2 March 1953 Commander MSTS requested replacement of these tugs by three Navy ATA's then in the Columbia Reserve fleet. The ex-Army tugs had not proved satisfactory in endurance, largely because when they were placed in the ocean towing service it was found necessary to limit their load drafts to ensure a satisfactory freeboard (given in the registers as 4'6.5" except 3'8.5" for ATA 243), meaning each tug could carry only 72% of its designed tankage with a corresponding reduction in steaming endurance. They were also not self-sustaining in fresh water. To maintain the stability rquired for ocean towing they had to ballast fresh and potable water tanks, and the fresh water needed to to flush and refill these tanks was not available in the quantities needed in the Aleutian Chain area. Finally, spare parts for them were not readily available in the Navy supply system because they were not Navy in design and equipment. On 31 Mar 1953 CNO proposed to provide ATA 174, 175, and 205 under civilian operation as replacements. The replacements subsequently became ATA 174 and 194, which were placed in service on 13 Aug 1953 and 31 Aug 1953 respectively allowing the inactivation of the ex-Army tugs. ATA 244, ex LT 156 (Army design 293), was a wooden-hulled equivalent to these tugs with about the same length and horsepower.
