USS Lassen (AE-3)

In the months previous to the outbreak of World War II for the United States, the Lassen made ammunition deliveries along both the Atlantic and Pacific Coasts of the U.S., and in July 1941, she steamed to Pearl Harbor, Territory of Hawaii, and then returned to the Atlantic Coast. On 22 November 1941, she departed from Norfolk, Virginia, en route to San Francisco, her homeport, and war broke out during this voyage.[2]

After round-trip delivery voyages to the Samoa Islands, the Fiji Islands, and Pearl Harbor, the Lassen began duty as an advanced base supply ship. Departing from San Francisco on 26 August 1942, the Lassen replenished naval ships in New Caledonia from 19 September to 17 January 1943. The ship arrived back at San Francisco on 23 January 1943 for repairs, the installation of radar equipment, and an upgrade in her air-defense armament.[2]

On 18 May 1943, the Lassen arrived at Espiritu Santo, in the New Hebrides, to resume dispensing war ammunition to the Navy fleet in the South Pacific. She also resupplied warships from the port of Efate, New Hebrides, and Noumea, New Caledonia, before returning to San Francisco on 24 November. An overhaul period in a drydock was a prelude to a more extensive stay in the war zone supplying the American warships that were battling the Imperial Japanese Navy.[2]

As a part of Vice-Admiral W. L. Calhoun's 7th Force, Pacific Fleet, the ammunition ship arrived at Majuro Atoll in the Marshall Islands on 2 February 1944. She replenished ships both in the Marshall Islands and at Manus Island in the Admiralty Islands. As part of the supply train of the fleet at Kossol Passage, Palau Islands, from 25 September to 2 October and at Ulithi Atoll from 4 October to 18 November 1944, she earned her first battle star. During the latter period, the Lassen rode out a severe typhoon, and she also underwent her first enemy air attack.[2]

Upon returning to the western Caroline Islands on 23 February 1945, the Lassen, along with her sister ammunition ships, worked out techniques for transferring large quantities of ammunition to warships while underway at sea. The Lassen exhibited this new ability and mobility by accompanying aircraft carrier Task Group 50.8 in raids from 13 March to 14 June 1945, while supporting the conquest of Okinawa campaign. The Lassen's third battle star was earned while accompanying carrier Task Group 30.8 from 8 July to 6 August off the coasts of Japan itself.[2]

The end of the war at V-J Day found the Lassen operating out of San Pedro Bay, Leyte. On 25 October, she departed the former war zone for the United States, via Eniwetok Atoll, where she embarked 112 passengers for their transportation to the West Coast.[2]

There was little need for ammunition ships like the Lassen during the period of huge peacetime demobilization of the Navy that followed. The vessel was noted for carrying out her dangerous ammunition delivery and handling duties without any serious incidents during the War in the Pacific. She was held in port first at Port Discovery, Washington, from 20 November 1945 to 2 March 1946, and then she proceeded down the West Coast in stages, arriving at San Diego on 27 March 1946. The ship was decommissioned on 15 January 1947 and entered the Pacific Reserve Fleet. She remained a part of this reserve fleet until she was struck from the Navy list on 1 July 1961 for disposal.[2]
