Class Notes:
FY 1942 (YDG-6), 1943 (YDG-7). On 8 Jul 43 BuShips selected YMS-344 for conversion to a degaussing vessel. On 20 Dec 43 CNO authorized conversion of YMS-480 (which had been PCS-1462 until 27 Sep 43) to a mobile degaussing vessel in place of PCS-1461. The YMS and PCS types were built to the same basic design, the PCS being a patrol variant of the YMS, except that the PCS (including those redesignated YMS) lacked the smokestack of the YMS type. The conversion of YDG-6 and probably YDG-7 included an elongation of the forecastle deck house, a rearrangement of the spaces therein, and removal of the 3"/50 gun foundation. Degaussing equipment included material for two complete independent coil ranges, portable magnetometers for calibration, cable and other equipment for deperming destroyers and smaller ships with the assistance of a minesweeper fitted with a diesel generator (although cables for deperming Liberty ships were omitted), and additional cable, floater hose, and accessories for the flash-D treatment of submarines. The relatively large boat stowed aft was for use in deploying degaussing gear.
