Class Notes:
On 15 June 1951 Commander MSTS asked CNO to assign an LSM from the Pacific Reserve Fleet to MSTS for duty in MSTSWESTPAC. He explained that such an amphibious type vessel was required for the logistic support of certain Air Force activities located on outlying Japanese islands. Japanese commercial shipping to these islands was unsatisfactory for transporting passengers and the conventional type vessels then assigned to MSTSWESTPAC were unsuitable for beach landings. CNO approved this request on 21 June 1951, directing the activation of a vessel from the Columbia River Group. COMSTSNORPACAREA (which covered the Columbia River) reported on 25 June that LSM 335 had been selected and would depart Astoria about 27 June. On 27 June COMSTS directed COMSTSNORPACAREA, after conversion and when the ship was in all respects ready for sea, to place the her in active status, in service as USNS LSM 335 (T-LSM 335). The ship was then to report to COMSTSWESTPAC for duty. The data in the 1956 Ships Data Book reflect several changes in characteristics from the basic LSM: the waterline beam was omitted, the max nav draft was reduced from 10' to 7', full load displacement rose from 1,090 to 1,095 tons and light displacement fell from 570 to 520 tons, accommodations were updated for a civilian crew, horsepower rating rose from 2,880 to 3,600, and one of her two ship service AC generators was replaced with a smaller DC one. (Data for many other ships were similarly updated in this volume based on postwar service.) After many years of service as T-LSM 335 she was reclassified T-AG 335 on 1 January 1969 retaining her LSM number.
