USS Ampere (PCE-919/AM-359/YDG-11/ADG-11) was originally planned as a

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

.

Design

Ampere was 184 ft 6 in (56.24 m) long, 33 ft (10 m) wide, had a draft of 9 ft 9 in (2.97 m), and displaced 625

Farrel-Birmingham single reduction gear alongside two propellers.^[1]

Construction

Drake was laid down on 24 November 1943, at Portland, Oregon by the Willamette Iron and Steel Works, and launched on 12 August 1944. On 20 April 1945, her name was canceled, and she was re-designated as a degaussing vessel, YDG-11. The ship was placed in service on 15 August 1945, the day after the Japanese surrender.^[2]

Service history

Due to the cessation of hostilities, YDG-11 saw little or no active service before being berthed with the

Naval Register on 1 July 1961, and she was sold on 21 June 1962, to the Philippine President Lines of Manila.^[2] Her final disposition is unknown.^[1]
