Returned to the United States Government after the war, on 10 December 1946, the ship resumed her former classification, AM-129, but not her former name. She was carried on the Naval Vessel Register as USS Strenuous (AM-129), and in the 1 January 1947 edition of the Naval Vessel Register merely as AM-129.
The vessel returned to its wartime designation, AM-129, upon being reacquired by the US Government on December 10, 1946.
