Joining the Navy he received an appointment as assistant surgeon, with the rank of Lieutenant (junior grade) on 22 July 1942, completed his internship in Montreal on 1 August 1942, and executed his oath of office on 4 September 1942.

Begor was laid down by the Defoe Shipbuilding Company in Bay City, Michigan, as a Rudderow-class destroyer escort with the hull number DE-711.

Departing 20 August with Underwater Demolition Team 21 embarked, she joined 3rd Fleet units en route to occupy Japan.

Proceeding to Yokosuka Naval Dockyard, she assisted in the de-militarization of the vessels there, and made dock surveys until departing for the United States on 25 September.

Begor returned in October, and during the next four years, carried out normal peacetime operations along the west coast, and made two cruises to the Far East from July 1947 through February 1948, and August through December 1949.

These highly successful and destructive raids slowed the enemy's resupply efforts, forcing the Communists to attempt to repair or rebuild the rail facilities by night while hiding the work crews and locomotives in tunnels by day.

Begor was struck from the Naval Vessel Register on 15 May 1975, and on 6 December 1976 sold for scrapping for $60,000 to National Metal and Steel Corporation, Terminal Island, California.
