Origin
USS Eldridge (DE-173), a Cannon-class destroyer escort, was a ship of the United States Navy named for Lieutenant Commander John Eldridge, Jr., a hero of the invasion of the Solomon Islands. Its keel was laid down by the Federal Shipbuilding and Dry Dock Company in Newark, New Jersey. Eldridge was launched on 25 July 1943, sponsored by Eldridge's widow Mrs. John Eldridge, Jr., and commissioned on 27 August 1943 with Lieutenant C. R. Hamilton, USNR, in command.

The Philadelphia Experiment was a naval military experiment alleged to have been carried out at the Philadelphia Naval Shipyard in Philadelphia, Pennsylvania, USA sometime around October 28, 1943. The U.S. Navy destroyer escort USS Eldridge was claimed to be rendered invisible (or "cloaked") to enemy devices.
