The USS Helios (ARB-12) was an Aristaeus-class battle damage repair ship constructed for the United States Navy during the final months of World War II. Originally laid down as LST-1127 by the Chicago Bridge & Iron Company of Seneca, Illinois, she was launched on 14 February 1945 and sponsored by Mrs. Emery Adams. Upon her commissioning on 26 February 1945, the vessel initially sailed down the Mississippi River to Baltimore, where she was decommissioned on 16 March 1945. Following her decommissioning, the ship underwent conversion into a battle damage repair ship at the Maryland Drydock Company of Baltimore. During this process, she was renamed Helios, inspired by the Greek sun-god, and recommissioned as USS Helios (ARB-12) on 23 July 1945. After her shakedown in Chesapeake Bay, she was ordered to the Pacific theater, departing Norfolk, Virginia on 27 August. However, by the time she arrived at Pearl Harbor on 29 September, World War II had concluded, and her services were no longer required in active combat zones. Subsequently, Helios traveled to Charleston and then to the Inactive Fleet Berthing Area at Green Cove Springs, Florida, where she decommissioned on 3 December 1946. She remained in reserve until 19 January 1962, when she was leased to the Brazilian government and renamed Belmonte (G-24). The vessel was sold outright to Brazil on 1 December 1977 and struck from the U.S. Naval Vessel Register shortly thereafter. She served in the Brazilian Navy until her decommissioning on 7 June 1997. Belmonte was ultimately sunk as a target on 19 March 2002. The USS Helios holds maritime significance as a WWII-era repair ship, representing the U.S. Navy’s logistical and repair capabilities during the war's final phase, and later served in the Brazilian Navy, extending her operational life into the late 20th century.
