USS Limestone
USS Limestone , a designated an unclassified miscellaneous vessel, was the only ship of the United States Navy to be named for limestone, a rock consisting chiefly of calcium carbonate, which yields lime when burned.
The ship was laid down 5 January 1944 by Barrett & Hilp, Belair Shipyard, in San Francisco, under a Maritime Commission contract, and named on 7 February 1944. Launched on 25 March 1944, sponsored by Mrs. Leo Heagerty, she was renamed and redesignated Limestone on 23 May 1944, acquired by the Navy on 14 October 1944, and placed in service the same day under command of Lt. W. T. Bresnahan USNR.
