- shipscribe's construction row for this hull: YDG-6 reclassified 12 Aug 43, builder Bellingham Marine, keel 8 Mar 43, launch 4 Jun 43, commissioned 14 Jan 44. Disposition row: decommissioned 9 Jul 46, stricken 19 Jul 46, disposal 7 Nov 47, fate 'MC/D', MA sale '7 Nov 47?'. Class notes: 'On 8 Jul 43 BuShips selected YMS-344 for conversion to a degaussing vessel' - i.e., the conversion decision predates commissioning; YDG-6 and probably YDG-7 conversions included elongation of the forecastle deck house, 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, cable and other equipment for deperming destroyers and smaller ships (with a generator-equipped minesweeper assisting), and cable, floater hose, and accessories for flash-D treatment of submarines. Ship note: 'Ex YMS-344 12 Aug 43. Unsigned receipt from buyer, Alaska Pipe & Salvage Co., is dated 5 Nov 47. Merc. JOE M. (U.S.) ca. 1947.' Class table specs: 196 light / 277 full tons; 136.0' oa (130.0' pp) x 24.5' x 8.5'; 2-20mm (1944); complement 28 (1944); 14 kts; 1,000 HP diesel machinery, 2 screws.

- shipscribe is a private scholarly compilation built from Navy records (the standard auxiliary-vessel reference), not the issuing agency's site - but it names the underlying BuShips/CNO authorization events and prints per-hull construction and disposition rows. Establishes identity, milestones, conversion scope, and disposal channel; contains no asbestos or materials content. The 'MC/D' fate code and the question-marked '7 Nov 47?' MA-sale column reflect the source's own uncertainty; the Alaska Pipe & Salvage receipt is described as unsigned.

At the San Pedro Bay (Leyte Gulf) anchorage, one of this class, the YDG-6, was available for magnetic-compass adjustment and also for compensation of degaussing-compass corrector coils. The YDG-6 was also equipped to inspect and make minor repairs on the degaussing systems of all ships and to calibrate the degaussing coils of vessels of YM's and comparable sizes.' The same history documents Service Squadron Ten's Leyte (San Pedro Bay) advanced-anchorage operations from October 1944 and its forward movement toward Okinawa in 1945.

Directly relevant to the open fate conflict: it contradicts 'lost in typhoon 1945' phrasing while corroborating NavSource's 'seriously damaged' line - the conflict is carried unresolved in ev-09 and gaps per the batch QA note.

No entry exists under 'YMS-344' - her logs are indexed under the service designation. Logs for the typhoon and decommissioning period (July 1945 - July 1946) are not indexed in SL44; whether they exist in an unindexed accession or were filed under a parent command is unresolved.

- The yard's build table lists this hull: official number 254445, customer US Navy, type 'minesweeper', YMS-344, 278 tons, 136 ft, delivered 26 November 1943, notes 'later YDG-6, sold 1946 as Joe M'. The yard history records: Bellingham Marine Railway Co. became Bellingham Marine Railway and Boatbuilding Co. in 1921 (new facility on the west side of Whatcom Creek waterway at Squalicum Creek, owned by O. I. Thorsen and J. G. Brown, joined 1928 by A. S. Nilsen), merged into Bellingham Shipyards with Bellingham Iron Works in 1941, renamed Bellingham Marine postwar, closed 1963.

The 'minesweeper' type label reflects the build contract designation - the hull was reclassified YDG-6 before commissioning and never operated as a minesweeper (see ev-08). O/N 254445 is the hull's later U.S. merchant documentation number consistent with the Joe M registry. No asbestos content.

- CONSOLIDATION/CORRECTION: YMS-344 and YDG-6 are one hull, not two vessels, and the hull was never an operating minesweeper. The sourced sequence: laid down 8 March 1943 under the YMS-344 contract designation at Bellingham; launched 4 June 1943; selected by BuShips for degaussing conversion 8 July 1943; reclassified District Degaussing Vessel YDG-6 on 12 August 1943 - more than five months before commissioning; commissioned USS YDG-6 on 14 January 1944. The minesweeper label survives only as the design basis (Navy YMS design, wooden hull) and the construction alias. Per the batch QA instruction the record consolidates the YMS-344 construction alias into the single YDG-6 hull and corrects the vessel-type metadata from minesweeper to degaussing vessel.

- FATE CONFLICT - OPEN, not resolved per batch QA instruction (Trill signs 1050-1055): one secondary compilation, the Naval Marine Archive special-purpose-craft table, lists 'YDG 6 | Bellingham MR | Bellingham WA | 136 | 270 | 1943 | Ex-YMS 344, lost in typhoon 1945' - a total-loss phrasing. The convergent record points the other way: the official CINCPAC typhoon appendix lists YDG 6 'damaged seriously afloat' (not sunk, not grounded); shipscribe documents a 7 November 1947 Maritime Commission disposal with an unsigned Alaska Pipe & Salvage Co. receipt dated 5 Nov 47 and merchant identity 'JOE M. (U.S.) ca. 1947'; NavSource and shipbuildinghistory document the 1949/1950 Los Angeles fishing-boat registrations as Joe M. The typhoon damage itself is not in dispute - what is open is whether the NMA 'lost' phrasing is an error or reflects a post-sale casualty not otherwise documented; 'fate unknown' (NavSource) is the carried end-state.

The weight of evidence (official 'damaged seriously afloat' + documented 1947 sale + 1949/1950 merchant registry) argues the 'lost in typhoon' phrasing is a compilation error conflating damage with loss, but no primary document affirmatively traces the hull past the 1950 registration - so the conflict is presented with both sides sourced rather than adjudicated.

- archives.gov/research/military/logbooks/naval-deck-logs, 'in commission' vs 'in service' retention paragraph and College Park holdings note
- Finding type
- historical_record
- Finding
- NARA's deck-log guidance states the retention rule that frames this hull's truncated log coverage: 'only deck logs of commissioned Navy ships are retained permanently'; most service vessels 'are classified as "in service" instead of "in commission" and do not possess their own administrative identity. Instead, they report through a higher-echelon parent command. While "in service" vessels may produce logs that are submitted to their parent command, those logs are not retained as permanent records.' Deck logs of commissioned ships dated 1941 and later are generally held at NARA College Park. For YDG-6 the indexed coverage (commissioning through 30 June 1945, ev-06) shows she was kept as a commissioned log-keeper; the absence of indexed logs for her final thirteen months is unexplained by the index itself - district-craft records are structurally thin and any later logs may sit under a parent command or never have been retained.
