USS Ampere (PCE-919/AM-359/YDG-11/ADG-11) was originally planned as a PCE-905-class patrol craft for the United States Navy, PCE-919, and laid down as an Admirable-class minesweeper, named Drake, for the male duck. Before she was commissioned, her name was cancelled and she was reclassified as a District Degaussing Vessel. She was later renamed Ampere, after the ampere, a unit of electric current, which takes its name from the French physicist André-Marie Ampère.
