- NavSource timeline and specifications for this hull: laid down 28 January 1943 by Henry C. Grebe and Co., Inc., Chicago, IL; launched 6 September 1943; 'Completed 20 November 1943 and commissioned USS YMS-406'; transferred to Norway 18 May 1945 and 'reclassified and commissioned HNoMS NYMS-406'; 'Named and reclassified HNoMS Rana (M 330) in 1948'; 'Returned to U.S. custody 7 June 1948 (on paper only); transferred to the State Department, Foreign Liquidation Commission and sold to Norway the same day'; struck from the Naval Register 12 August 1948; 'Struck from the Norwegian Naval Register in August 1962. Fate unknown.' Call sign Nan-Peter-Item-Jig. Specs: displacement 270 t; length 136'; beam 24'6"; draft 8'; speed 15 kts; complement 32; armament one 3"/50 dual-purpose mount, two 20mm mounts, two depth-charge projectors; propulsion two 880 bhp General Motors 8-268A diesel engines, Snow and Knobstedt single reduction gear, two shafts. Page states explicitly: 'There is no DANFS History currently available for YMS-406.' Photo captions document a builder's photo dated 19 November 1943 (NHHC NH 43511) and 'YMS-305, YMS-406 and YMS-380 in a French port sometime after D-Day.'

- The ship's own digitized action report (YMS-406/A16, Serial 001, 4 Aug 1944, Lt. H.J. White, USNR, commanding): YMS-406 was SENIOR SHIP of 'Y' Squadron 1 (Y-1) with the squadron commander (Commander G. W. Allen, USN) and his aide (Lt.(jg) Batten, USNR) embarked; squadron comprised sweepers YMS-406/378/305/377/379/380, spare sweepers YMS-375/356, dan layers YMS-382/381, salvage-rescue YMS-358. Departed Plymouth 3 June 1944; after the one-day postponement swept the mile-wide boat channel and Fire Support Channel No. 3 off Utah Beach on D-Day (6 June), danning both sides, no mines exploded by the squadron that day; caught in crossfire between a shore battery and a British cruiser in the fire-support channel at 0550 - near misses, no hits; the 'QH' gear had failed 5 June and was retuned 13 June by a USS Bayfield technician; 7 June MA sweep over Banc du Cardonnet exploded 25 mines astern (406 as guide did not stream gear); on 9 June the squadron split and YMS-406 became senior ship of division Y-1A (YMSs 406, 305, 356, 358, 375, 377, 379); magnetic-acoustic sweeps continued through 17 June (8 mines exploded that day, six acoustic); 18 June the Y-1A vessels returned to Plymouth for repairs and supplies. Part III: only ordnance expended were smoke pots. Part IV: 'No battle damage was sustained by this vessel.' Part VI: 'No personnel casualties resulted.' First endorsement (Commander 'Y' Squadrons, aboard USS Chimo ACM-1, 5 Aug 1944): 'The performance of YMS 406 has been more than satisfactory during the assault phase and in all subsequent operations.' Endorsed up the chain to CominCh (received 18 Aug 1944).

Western Task Area totals: 78 moored and 117 ground mines swept, 15 ship casualties/spontaneous explosions; Y Squadrons swept 67 ground mines plus 2 moored mines sunk by gunfire.

- Class/type documentation: 'The wood-hulled YMS proved to be one of the U.S. Navy's more durable and versatile types through a quarter-century of service, filling a variety of roles for a number of navies. All 481 ships of this type had the same general characteristics. The only significant variation within the type was one of appearance; YM-1 through 134 had two stacks, YMS-135 through 445, 480, and 481 had one, while YMS-446 through 479 had none. Originally rated as service craft, they were used during World War II for inshore sweeping to prepare the way for amphibious assaults.' YMS-406 falls in the one-stack subclass (YMS-135 through -445). Class spec block: displacement 320 tons (full); length 136'; beam 24'6"; draft 6'1"; speed 13 knots; armament 1 3"/50, 2 20mm, 2 depth charge tracks + 2 extensions, 2 depth charge projectors; complement 4 officers + 29 crew; diesel engines, twin screws, 500 h.p.

- Finding
- A wood-hulled, diesel-driven auxiliary motor minesweeper built in 1943 sits inside the Navy's documented asbestos-use era. Era-standard applications aboard a small diesel minesweeper of this period were engine and diesel-exhaust lagging, gaskets, valve packing, and electrical insulation in the confined machinery spaces. As a diesel-driven wooden vessel she carried no steam plant and no boiler lagging - the boiler/turbine insulation pathway of steam vessels does not apply, and her wood-hulled construction reduced (but did not eliminate) insulation scope relative to steel steam vessels of the era.
