USNS Private Jose F. Valdez (T-AG-169)

USNS Private Jose F. Valdez (T-AG-169), named after World War II Medal of Honor recipient PFC Jose F. Valdez, was a technical research ship in operation during the 1960s. The "Galloping Ghost of the Ivory Coast" or "Grey Ghost of the African Coast", as she was affectionately called by her crew, was deployed around Africa from 1961 until 1969.

Army service, 1945–1949
The Private Jose F. Valdez, was launched as Round Splice on 27 October 1944, sponsored by Mrs. Guy R. Porter, and transferred to the American Ship Building Company, Chicago, Illinois, for completion on 15 December 1944. The ship was delivered to the U.S. Army for operation on 16 February 1945. Round Splice, owned by the Maritime Commission and operated by the Army Transportation Service during and after World War II, and was renamed Private Jose F. Valdez in 1947.

Transfer to the Navy, 1950–1959
On 2 September 1950 she was acquired by the United States Navy, designated T-APC-119, and assigned to Military Sea Transportation Service. Manned by a civil service crew she operated in the Gulf of Mexico and Caribbean areas until August 1951. Between then and December she cruised the Mediterranean Sea and in January 1952 began runs to Newfoundland and Greenland which continued until she was ordered inactivated in late 1959. On 22 December she arrived in the James River National Defense Reserve Fleet berthing area and was transferred to the custody of the Maritime Administration.

Technical Research Ship, 1961–1969
Private Jose F. Valdez was reacquired by the Navy in August 1961. Converted to a Technical Research Ship and reassigned to MSTS, she departed Brooklyn, her homeport, in November 1961 on the first of her extended cruises to the South Atlantic and Indian Oceans.

The USNS designation indicates that the ship was manned by civilians. A crew of approximately 55 civilians operated the ship while a detachment of approximately 100 Navy personnel carried out the research operations. The Navy detachment typically included three officers; almost all enlisted men were Communications Technicians (a rating that has been renamed Cryptologic Technician). An advantage of the USNS designation is that the ship was not required to return to an American port on a regular basis. Thus the first deployment of the Valdez started in 1961 and she did not return to the USA until 1967.

Operation in African waters
Since the "Happy Jose" did not regularly return to the USA, the crew was rotated by flying them to a major port city in Africa, such as Cape Town. This occurred on an annual basis. The old crew would be flown back to the USA.

The Valdez was typically at sea for about 30 days and then spent four or five days in port. Some of the sub-Saharan ports of call, from West to East, were Dakar, Senegal; Freetown, Sierra Leone; Monrovia, Liberia; Abidjan, Ivory Coast; Lagos, Nigeria; Brazzaville, Republic of Congo; Luanda, Angola; Walvis Bay, Southwest Africa (now Namibia); Cape Town, South Africa; Port Elizabeth, South Africa; Durban, South Africa; Lourenço Marques (now Maputo), Mozambique; and Mombasa, Kenya.

A brush with fate
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: the USS Oxford (AGTR-1) and USS Jamestown (AGTR-3) were in Southeast Asia, the USS Georgetown (AG-165) and USS Belmont (AGTR-4) were in South America, and the USNS Sgt. Joseph E. Muller (T-AG-171) was off Cuba.

Choice of a ship for the operation narrowed between the Valdez, then headed from the eastern Mediterranean to Gibraltar, and the USS Liberty (AGTR-5) in port at Abidjan, Ivory Coast. The NSA selected the 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 the Valdez, at the beginning of a deployment. On 23 May 1967 the Liberty was diverted for duty in the eastern Mediterranean. The Liberty stopped at Rota on 1 June and departed the next day for the eastern Mediterranean. Eastbound Liberty passed westbound Valdez night of June 5/6. June 7 Contact X (Valdez was Contact A ) removed from Liberty's  navigation chart. Seven days after arriving Rota, the Liberty was attacked by Israeli forces and suffered heavy damages, with 34 crew members killed and 171 injured (see the USS Liberty incident).Valdez arrived in Bayonne, New Jersey in June 1967.

Final deployments
After repair and overhaul, the Valdez departed for her second extended tour in the African region on 18 September 1967. She returned to the USA unexpectedly early in September 1968 for installation of TRSSCOMM (Technical Research Ship Special COMMunications), a system that could relay messages directly to Washington by bouncing a microwave signal off the moon. This was not a new system; it had already been used on the USS Liberty (AGTR-5) and the USS Oxford (AGTR-1). 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 the receiving station at Cheltenham, Maryland, or to one of the other Navy SIGINT ships. The TRSSCOMM had the advantage of being able to transmit large quantities of intelligence information very rapidly without giving away the ship's location to hostile direction finding equipment or interfering with incoming signals. But its major disadvantage is that it could only work if the moon was visible and the stabilization system worked properly.

The third extended deployment commenced on 22 January 1969 when the Valdez transited to Africa via Recife, Brazil. The Valdez was ordered home later that year to prematurely end her final deployment. All the vessels in the Technical Research Fleet were inactive by 1970.

Final fate
The Maritime Administration assumed custody of the Valdez on 7 November 1969. She was struck from the Naval Vessel Register, 15 August 1976 and transferred for disposal. She sold on 27 July 1977 and scrapped by Consolidated-Andy Inc., Brownsville, Texas later that year.
