The U.S. Navy destroyer Rinehart (DE-196), built by the Federal Shipbuilding and Dry Dock Company of Newark, New Jersey, was laid down on 21 October 1943 and commissioned on 12 February 1944. Lieutenant Partee W. Crouch was the ship's first commanding officer.
The Rinehart began convoy escort duties on 8 May 1944, when she sailed for New York to begin the first of many escort cruises. She escorted valuable cargo to and from the U.S. East Coast to ports in Europe and North Africa until the end of May 1945.
Following the cessation of hostilities with Germany, the Rinehart was ordered to the Pacific, arriving in Pearl Harbor on 21 July 1945, via the Panama Canal and San Diego.
After training in Hawaiian waters, the Rinehart left Pearl Harbor on 8 August acting as an escort for an Eniwetok-bound convoy. After delivering her charges safely on 16 August, the Rinehart was assigned as ready duty ship and also was assigned to patrolling on the barrier line between convoy lanes. On 12 September the Rinehart's crew recovered LCVP-3832 which had been adrift off the island of Eniwetok.
