USSOceanus (ARB-2) was planned as aUnited States NavyLST-1-classtank landing ship, but was redesignated as one of twelveAristaeus-class battle damage repair ships built for theUnited States Navy duringWorld War II. Named forOceanus (believed to be theworld-ocean inclassical antiquity), she was the only US Naval vessel to bear the name.

The ship was laid down asLST–328 on 12 November 1942, at thePhiladelphia Navy Yard; redesignated ARB-2 on 25 January 1943, she was then launched on 11 February 1943, and commissioned on 22 May 1943.^[2]

Followingshakedown inChesapeake Bay,Oceanus departedNorfolk, Virginia on 23 July 1943 for the Pacific, arriving atNouméa, New Caledonia 18 September. She remained there, convertingLCIs to shoal-draftgunboats and making emergency repairs to damaged vessels. On 28 October, she shifted toEspiritu Santo, thence, departing on 1 July 1944, toFlorida Island. On 9 September 1944, she departed theSolomon Islands in TG 31.4 and on 20 September, arrived atKossol Roads,Palaus. There she repaired, often while underway, craft and vessels damaged in the assaults against those islands and against thePhilippines. In February 1945, she steamed toGuam to join TG 51.5 for theIwo Jima invasion, arriving on 20 February, and remaining until 17 March.^[2]

TheOkinawa campaign next tookOceanus toKerama Retto, where work on ships damaged bykamikazes and bombs kept her on a round-the-clock schedule into mid-May. On 14 May, she shifted to theHagushi anchorage for emergency repairs to the battleshipNew Mexico. Completing the work and returning to Kerama Retto's "Scrap Iron Row" on 21 May, she remained until early June when she steamed to the Philippines.^[2]

Arriving atLeyte 15 June, she remained inSan Pedro Bay until after theend of the War.^[2]

Post-war duties took her to Okinawa, then toChina. AtShanghai from October into December, she serviced landing and patrol craft assigned to China Group. On 25 December, she headed back to the United States to prepare for inactivation. Decommissioned 15 January 1947, she was berthed atSan Diego, as a unit of thePacific Reserve Fleet until struck from theNaval Vessel Register 1 July 1961,^[2] and sold 3 May 1962 toZidell Exploration of Portland, Oregon for scrapping.
