In yard hands at Terminal Island, California, for post-shakedown availability until 10 October, Uvalde got underway and churned out of Los Angeles harbor, bound for San Francisco.

Uvalde spent Christmas at Manus before she got underway on her first "mission of war" as part of Task Group (TG) 77.9 on 2 January 1945, shaping course for the island of Luzon.

For six weeks, the attack cargo ship participated in the practice evolutions that ultimately led up to the final big assault landing of the war in the Pacific — the invasion of Okinawa in the Ryūkyūs.

At 0559 on 2 April, Uvalde's gunners drew their first blood, downing a suicide aircraft making a run on the nearby attack transport USS Latimer (APA-152).

Up until mid-1950, Uvalde transported troops and cargo to American outposts in Asia, supporting the United States presence in that area of the world Uvalde participated in the United Nations efforts to stem North Korean aggression after that nation invaded neighboring South Korea in June 1950, deploying to Korean waters with troops and cargo on numerous occasions.

The attack cargo ship subsequently made three round-trip voyages, touching at Sasebo and Yokosuka in the west and Oakland in the east over the remainder of 1951.

She visited Korean waters in the latter half of the month of March 1952, touching at Sokcho Ri and Paengyong Do before resuming her west coast-to-Japan shuttle voyages with her termini at Oakland, Sasebo, and Yokosuka.

Uvalde overhauled at Mare Island into mid-February, 1953, after which time she conducted the usual under way training evolutions before resuming west coast-to-Japan shuttle voyages.

February through July of the following year, 1954, was spent in shuttle service between the Naval Supply Center, Oakland, and the Far East, with a recreational visit to Nagasaki in April.

During July, the ship arrived at Yokosuka and, after a trip to Sasebo and return, loaded a cargo of rice and medical supplies, setting sail for French Indochina to assist in "Operation Passage to Freedom."

Uvalde reached Tourane Bay, French Indochina, on 28 August and remained there, supporting "Passage to Freedom" operations until 10 September, when she got underway to return to Oakland.

Over the next few years, Uvalde's routine would remain much the same, sailing back and forth across the Pacific on the supply line from the west coast of the United States to American military bases in the Far East.

Ordered to duty with the Atlantic Fleet, the attack cargo ship — with a new lease on life — got underway for Guantanamo Bay, Cuba, and five weeks of training in December.

After a voyage that had taken her via Mazatlán, Mexico; the Panama Canal; and Guantanamo (where she engaged in refresher training operations as scheduled), Uvalde reached her new assigned home port, Norfolk, Virginia, in February 1962.

Uvalde subsequently trained out of Little Creek, Virginia, for 10 days in July before resuming scheduled independent ship exercises and upkeep periods out of, and at, Norfolk.

During that cruise — lasting into mid-March 1966 — Uvalde operated with Task Force 61, visiting Marseilles and Toulon, France; Malta; Naples, Genoa, and Livorno, Italy; Barcelona and Mazarron, Spain; and Porto Scudo and Santa Manza, Corsica.

Reaching the end of the deployment, Uvalde left Palma, Majorca, in her wake on 17 March, bound for Rota, Spain, the turnover point, where she would be relieved of her duties with the 6th Fleet.

The attack cargo ship subsequently deployed to the Mediterranean two more times in her career, from April to August 1967 and again during the summer of 1968, returning to Morehead City, N.C., on 14 September and Norfolk the following day.

Transferred to the Maritime Administration on 26 June 1969 for disposal, Uvalde's hulk was simultaneously sold to Levin Metals Corp., of San Jose, California, and scrapped.
