Class Notes:
On 11 October 1962 the director of the Navy's Ships Material Readiness Division wrote to MARAD that, following the selection of two Victory ships earlier in the year that became AGM 8 and AK 279, the Navy now had a requirement for two additional Victory ships for conversion to Technical Research Ships. Once again the Navy requested two ships be reserved on each coast, SIMMONS VICTORY and IRAN VICTORY on the West Coast and BINGHAMTON VICTORY and FURMAN VICTORY on the East Coast, the final choice to be based on the choice of contractor. The West Coast ships were ultimtely selected, although FURMAN VICTORY on the East Coast soon became AK 280. The characteristics for AGTR 2-3 (SCB No. 192A) generally applied to these ships and were used in early design work, although unlike in AGTR 2-3 the installation of passive roll-stabilization tanks was feasible of accomplishment during their conversion and this feature was included in the contract plans and specifications. Increased deck area for communications facilities and Research Operations was been included in the contract plans, made possible by the relatively large basic hull and available weight and stability margins. Approved characteristics for a Technical Research Ship (AGTR), SCB Project No. 192B (FY 1963), were promulgated on 5 July 1963 with a single change on 24 February 1964. On 8 June 1963 the classifications and names IRAN VICTORY (MCV 94) and SIMMONS VICTORY (MCV 182) were changed to BELMONT (AG 167) and LIBERTY (AG 168) for the two technical research ships then undergoing conversion. The dish antenna on the bows of both ships as completed was probably for the Technical Research Ship Special COMMunications (TRSSCOMM) system, which could relay messages directly to Washington by bouncing a microwave signal off the moon. This system consisted of a sixteen-foot, dish shaped antenna mounted on a movable platform and capable of bouncing a 10,000 watt microwave signal off a particular spot on the moon and down either to receiving stations at Cheltenham or Maryland or to other Navy SIGINT ships. It was also fitted in PVT JOSE F VALDEZ (AG 169, ex APC 119).

In May 1967 tensions were rising in the Middle East between Israel and her Arab neighbors; this resulted in the Six-Day War in June 1967. The National Security Agency (NSA) decided to deploy a SIGINT collection ship to the area to monitor the situation. Most of the technical research ships were too far away: OXFORD and JAMESTOWN were in Southeast Asia, GEORGETOWN and BELMONT were in South America, and USNS SGT JOSEPH E MULLER was off Cuba. Choice of a ship for the operation narrowed between USNS PVT JOSE F VALDEZ, then headed from the eastern Mediterranean to Gibraltar, and LIBERTY, in port at Abidjan, Ivory Coast. The NSA selected LIBERTY because she had superior cruising speed (18 knots vs. 8 knots for VALDEZ), because her VHF/UHF multichannel collection capability was better, and because she was, unlike VALDEZ, at the beginning of a deployment. On 23 May 1967 LIBERTY was diverted for duty in the eastern Mediterranean. She stopped at Rota on 1 June and departed the next day for the eastern Mediterranean.

See other sources for the ensuing attack by Israeli aircraft and MTBs on LIBERTY on 8 June 1967. After this incident and the seizure of PUEBLO in 1968, BELMONT was taken out of service at the beginning of 1970 with the other large and small intelligence collection ships.
