USS Belmont (AGTR-4)

On 26 April, Belmont passed between the Virginia Capes into the Atlantic Ocean and laid in a course for the West Indies. Two days at sea, the ship received orders to proceed to the vicinity of the Dominican Republic where, four days earlier, a revolt of left-wing factions had broken out. Belmont remained on station observing conditions until the middle of July. On 13 May, she headed back to Norfolk where she arrived four days later. After almost two months in port, the ship once more got underway on 14 September and spent about a month cruising in the West Indies before transiting the Panama Canal in mid-October. For the remainder of the year, she conducted operations along the western coast of South America, including visits to Valparaíso, Chile, and Callao, Peru.

New Year's Day 1966 found her at anchor in Callao. Two days later she weighed anchor to return to the Panama Canal Zone. Belmont retransited the canal on 21 January 1966 and moored in Norfolk on the 28th, where she remained for almost seven weeks for upkeep and shipyard availability. On 16 March 1966, the ship embarked upon another deployment to the western coast of South America. She transited the Panama Canal on 28 and 29 March 1966 and, for the next eight weeks, cruised along the coasts of Peru and Chile. Belmont returned to the Panama Canal Zone for a five-day visit between 23 and 28 May 1966. On the latter day, she departed Panama and embarked upon five weeks of operations in order to spy on French atomic tests in French Polynesia (12 June 1966). The ship arrived back in the Panama Canal Zone on 13 July 1966, transited the canal the next day, and reentered Norfolk on 20 July.

After seven weeks of upkeep in her homeport, Belmont stood out to sea on 7 September 1966, bound for her third assignment in the Pacific coastal waters of South America. She transited the Panama Canal again on 19 September 1966, and two days later shaped a course for her zone of operations. At the conclusion of that assignment, the ship returned to the Canal Zone on 4 November 1966. She proceeded through the canal on 8 November 1966 and then set course for Norfolk. Belmont reentered her homeport on 14 November 1966, and spent the remainder of the year in the Norfolk Naval Shipyard installing communication gear.

The spy ship spent the first month of 1967 completing the installation of her new communications equipment and testing it. On 1 February 1967, Belmont loosed her mooring lines to begin an extended cruise to the Southern Hemisphere, one that included a circumnavigation of the South American continent. Hydrographic and communications research highlighted the five-month voyage as did visits to sundry South American ports. Belmont completed her circuit of the South American continent on 3 June 1967 when she transited the Panama Canal and laid in a course for Norfolk. The technical research ship pulled into her homeport on 9 June 1967 and commenced a repair period. Her hull and various items of equipment received repairs over the next two months.

On 14 August 1967, she stood out of the Chesapeake Bay bound for the Indian Ocean. The ship rounded the Cape of Good Hope on 5 October 1967, and spent the following six weeks engaged in special operations along the eastern coast of Africa. On 22 November 1967, she redoubled the cape and, after an overnight stop at Monrovia, Liberia on 2 and 3 December 1967, pointed her bow west for the homeward voyage. Belmont arrived back at Norfolk on 12 December 1967, and spent the remainder of the year engaged in holiday leave and upkeep.

January 1968 found Belmont still at Norfolk. On 26 January, she began regular overhaul at the Norfolk Naval Shipyard. She emerged revitalized on 14 May 1968 and put to sea to conduct refresher training in the Guantanamo Bay, Cuba, operating area. The ship completed post-overhaul training on 14 June 1968 and, after a visit to San Juan, Puerto Rico, embarked upon her second deployment to the coasts of Africa. On 2 July 1968, she arrived off Cape Palmas and commenced operations along Africa's western coast. That phase of the assignment lasted until 25 September 1968, at which time she passed the Cape of Good Hope and entered the Indian Ocean. That portion of her mission proved relatively brief, occupying her time during the last week in September 1968 and the month of October 1968. On 1 November 1968, Belmont retraced her course around the Cape of Good Hope and steamed back into the Atlantic Ocean. The ship stopped over at Recife, Brazil, from 13 to 16 November 1968, and then headed for the northeastern coast of South America and a series of operations in that vicinity. Belmont completed the last mission of the cruise on 24 November 1968 and headed home. She moored at Norfolk on 28 November 1968 and remained there for the rest of 1968.

During the first half of 1969, Belmont stayed in or, infrequently, operated near Norfolk. A restricted availability followed by sea trials occupied the first three months of the year. Early in April 1969, she began installation of additional equipment. May 1969 brought tests and type training in the Virginia Capes operating area. In June 1969, she began preparations for overseas movement. On 17 June 1969, Belmont left her berth at the Norfolk Naval Station bound for her first and only tour of duty with the U.S. 6th Fleet in the Mediterranean. She passed through the Strait of Gibraltar on 28 June 1969 and joined the 6th Fleet, two years after the Israeli attack on her sister ship, USS Liberty. Over the next four months, Belmont ranged the length and breadth of the Mediterranean conducting a series of special operations and making stops at ports along the Mediterranean littoral. However, this technical research (spy) ship spent the majority of her time in the eastern portion of the sea near Kythira, Greece, and the island of Crete. Belmont concluded this last deployment of her career at Rota, Spain (never made it to Rota) on 21 October 1969, and steered a course back to the United States that same day.

Belmont arrived back in Norfolk on 3 November 1969. Three weeks later, the ship received the close scrutiny of a board of inspection and survey. As a result, she was found to be of limited naval value. Accordingly, Belmont was decommissioned at Norfolk on 16 January 1970, and her name was struck from the Naval Vessel Register that same day. On 24 June 1970, over 26 years after her construction during World War II, she was sold to the Boston Metals Co. in Baltimore, Maryland, for scrapping.
