Allentown departed New Orleans on 3 April 1944 bound for shakedown training at Bermuda. After about a month of training, she set a course for New York City escorting the Norwegianmerchant ship SS Norden. She arrived in New York on 13 May 1944 and underwent post-shakedown repairs and alterations. Near the end of June 1944, she stood out of New York in the screen of a convoy. She arrived at Norfolk, Virginia, on 28 June 1944 and entered the Norfolk Navy Yard at Portsmouth, Virginia, for additional repairs. She completed repairs in mid-August 1944 and returned to New York, where she arrived on 16 August 1944. Soon thereafter, she returned to sea as a unit of Escort Division 33 in the screen of a convoy bound for the Pacific.
Steaming via the Panama Canal and Bora Bora in the Society Islands, Allentown reached the northern coast of New Guinea at the end of September 1944. She then began patrol and escort duty in the New Guinea area. At the end of October 1944, she participated briefly in the occupation of the island of Morotai in the Molucca Islands. In mid-November 1944, she began escorting convoys between Hollandia, New Guinea, and Leyte in the Philippines in support of the U.S. invasion there. Those duties and convoy-escort missions between the various islands of the Philippine archipelago occupied her time until early March 1945. On 9 March, Allentown joined the escort of a Ulithi-bound convoy on the first leg of her voyage back to the United States. She arrived at the Puget Sound Navy Yard in Bremerton, Washington, on 7 April 1945.
Allentown was decommissioned on 12 July 1945 at Cold Bay and transferred to the Soviet Union under Lend-Lease immediately[1] along with nine of her sister ships, the first group of patrol frigates transferred to the Soviet Navy. Commissioned into the Soviet Navy immediately,[3]Allentown was designated as a storozhevoi korabl ("escort ship") and renamed EK-9[2] in Soviet service. On 15 July 1945, EK-9 departed Cold Bay in company with nine of her sister ships – EK-1 (ex-Charlottesville), EK-2 (ex-Long Beach), EK-3 (ex-Belfast), EK-4 (ex-Machias), EK-5 (ex-San Pedro), EK-6 (ex-Glendale), EK-7 (ex-Sandusky), EK-8 (ex-Coronado), and EK-10 (ex-USS Ogden (PF-39)) – bound for Petropavlovsk-Kamchatsky in the Soviet Union. EK-9 served as a patrol vessel in the Soviet Far East.[5]
In February 1946, the United States began negotiations for the return of ships loaned to the Soviet Union for use during World War II. On 8 May 1947, United States Secretary of the NavyJames V. Forrestal informed the United States Department of State that the United States Department of the Navy wanted 480 of the 585 combatant ships it had transferred to the Soviet Union for World War II use returned, EK-9 among them. Negotiations for the return of the ships were protracted, but on 15 October 1949 the Soviet Union finally returned EK-9 to the U.S. Navy at Yokosuka, Japan.[6]
Reverting to her former name, Allentown remained at Yokosuka, laid up in the Pacific Reserve Fleet, until 2 April 1953 when she was loaned to Japan. She served the Japan Maritime Self-Defense Force as JDS Ume (PF-9) (うめ (PF-9), "Japanese apricot").[7]Ume was redesignated PF-289 on 1 September 1957.[7] The United States struck her name from the Navy list on 1 December 1961 and transferred her to Japan on a permanent basis on 28 August 1962.
Ume was reclassified as an "auxiliary stock craft" and renamed YAC-14 on 31 March 1965.[7] Decommissioned on 31 March 1970, she was returned to U.S. custody on 12 July 1971 and broken up in Taiwan later that year.[8]
