USS Allentown (PF-52)

USS Allentown (PF-52), a United States Navy Tacoma-class frigate in commission from 1944 to 1945, has thus far been the only U.S. Navy ship to be named for Allentown, Pennsylvania. She later served in the Soviet Navy as EK-9 and in the Japan Maritime Self-Defense Force as JDS Ume (PF-289) and as YAC-14.

Construction and commissioning
Allentown was laid down on 23 March 1943 at the Froemming Brothers, Inc., shipyard in Milwaukee, Wisconsin, under a Maritime Commission contract (MC hull 1477). Launched on 3 July 1943, sponsored by Miss Joyce E. Beary, she was moved to New Orleans, Louisiana, where she fitted out and was commissioned on 24 March 1944 with Commander Garland W. Collins, USCG, in command.

U.S. Navy, World War II, 1944-1945
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 Norwegian merchant 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 Philippine Islands 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.

After completing an overhaul, Allentown departed Puget Sound on 7 June 1945, bound for Kodiak in the Territory of Alaska. Earmarked for transfer to the Soviet Navy in Project Hula, a secret program for the transfer of U.S. Navy ships to the Soviet Navy in anticipation of the Soviet Union joining the war against Japan, Allentown joined her sister ships USS Charlottesville (PF-25), USS Long Beach (PF-34), USS Belfast (PF-35), USS Glendale (PF-36), USS San Pedro (PF-37), USS Coronado (PF-38), USS Machias (PF-53), and USS Sandusky (PF-54) in getting underway from Kodiak on 13 June 1945 bound for Cold Bay, Alaska, where they arrived on 14 June 1945 to enter Project Hula. Training of Allentown's new Soviet Navy crew soon began at Cold Bay.

Soviet Navy, 1945–1949
Allentown was decommissioned on 12 July 1945 at Cold Bay and transferred to the Soviet Union under Lend-Lease immediately along with nine of her sister ships, the first group of patrol frigates transferred to the Soviet Navy. Commissioned into the Soviet Navy immediately, Allentown was designated as a storozhevoi korabl ("escort ship") and renamed EK-9 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.

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 Navy James 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.

Japan Maritime Self-Defense Force, 1953–1971
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-289). 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. Decommissioned on 31 March 1970, she was returned to U.S. custody on 12 July 1971. Her final disposition is unknown.

Awards
The U.S. Navy awarded Allentown two battle stars for her World War II service.
