The Calmer Steamship Corp. operated Francis J. O'Gara for MARCOM from 30 June 1945 until 4 June 1946. Francis J. O'Gara's cruises during this period included one to the US West Coast of the United States and one to various European ports.^[4]

On 4 June 1946 Francis J. O'Gara was laid up in the Hudson River Reserve Fleet, Jones Point, New York, of MARCOM. From 28 January 1947 until 14 January 1948, Francis J. O'Gara was operated by the Waterman Steamship Company and then the South Atlantic Steamship Company. During this period she made cruises to Europe, the Near East, and the Orient. On 20 January 1948, Francis J. O'Gara was laid up in MARCOM's Mobile, Alabama, reserve fleet.^[4]

US Navy service

On 22 May 1956, the US Navy acquired Francis J. O'Gara to be converted into an Ocean Station Radar Ship.^[4]

Francis J. O'Gara was towed from Mobile, to the Philadelphia Naval Shipyard, Philadelphia, Pennsylvania, where conversion was begun to equip her with the electronic detection equipment and communication gear necessary for her role with the Continental Air Defense Command. She was assigned the Navy hull number YAGR–10 and commissioned Outpost, 6 February 1957.^[3][4]

After shakedown training out of Guantanamo Bay, Cuba, Outpost reported to her homeport, Davisville, Rhode Island, 3 June 1957. On 28 June, the ship steamed seaward on her first patrol and on 30 June, relieved Brister on picket station. The ship returned to Davisville, 19 July, but by 24 July, was underway for another patrol setting the pattern of patrols interrupted by short periods in port.^[4]

Outpost made a total of six patrols in 1957. These patrols continued into 1958. Outpost's designation was changed to AGR–10 28 September 1958.^[4]

During the first half of 1961, Outpost steamed on station. But in August she steamed south to Florida and the Bahamas. From October 1961 to January 1962, she underwent overhaul at Boston, Massachusetts.^[4]

Outpost continued her Atlantic patrols in 1962, buttoning up for wartime steaming during the Cuban Missile Crisis. The onset of 1963 found Outpost steaming on station as before. In late July the ship visited Halifax, Nova Scotia.^[4]

From August through the end of 1963, Outpost maintained a record of no misses in reporting air contacts. She visited Halifax, again in November before putting into her homeport for the holidays. Early in 1964, she resumed her patrols and continued this pattern of operation until decommissioning 1 July 1965.^[4]
