USS Rockford (PF-48), a Tacoma-class frigate in commission from 1944 to 1945, thus far has been the only ship of the United States Navy to be named for Rockford, Illinois. She later served in the Soviet Navy as EK-18 and in the Republic of Korea Navy as ROKS Apnokkang (62).

Originally classified as a patrol gunboat, PG-156, Rockford was reclassified as a patrol frigate, PF-48, on 15 April 1943. She was laid down on 28 August 1943, by Consolidated Steel Corporation in Los Angeles, California, launched on 27 September 1943, sponsored by Mrs. Harry L. Crotzer, and commissioned on 6 March 1944 with Commander D. H. Bartlett, USCG, in command.

Following shakedown off Los Angeles, Rockford, manned by a United States Coast Guard crew, reported to the United States Pacific Fleet and got underway on 25 June 1944 for the Southwest Pacific. On 2 July 1944 she attacked a Japanese submarine with depth charges, doing some damage. She made a second antisubmarine attack with Hedgehogs antisubmarine mortars on 7 July 1945. Continuing her voyage, she proceeded via Espiritu Santo to Australia, arriving at Cairns, Queensland, on 23 July 1944.
