The window begins on her documented completion/in-service date and ends 22 December 1945 - after her 9 October 1945 typhoon loss, covering the post-loss salvage/strip period, and before her striking (8 January 1946) and destruction (12 January 1946). Logbooks of this era are RG 24 (Records of the Bureau of Naval Personnel), Entry 118 (NAID 581208), held at the National Archives at College Park.

- The CinCPac report names this hull in its typhoon-damage appendix: 'YMS 384 | Sunk'. The report documents Typhoon Louise, 9 October 1945 at Buckner Bay (Nakagusuku Wan), Okinawa: winds of 80 knots with gusts far higher, 30-35 foot seas; 12 ships and craft sunk, 222 grounded, 32 damaged beyond shipboard repair; personnel casualties 36 killed, 47 missing, approximately 100 seriously injured. ComServDiv 104 (Commodore T. J. Keliher) conducted salvage; by 19 November, 79 ships refloated and 132 under repair, with 53 badly damaged vessels being decommissioned, stripped, and abandoned. Sister hulls in the same appendix: 'YMS 383 | Grounded - Sunk, strike from register'; YMS-90, -146, -148, -151, -193, -275, -292, -308, -348, -381, -424, -442, -454, -590 and others in grounded/refloated/damaged categories.

- Finding
- NEGATIVE LISTING: the official U.S. Pacific Fleet organization for 1 May 1945 does not list YMS-384. The minecraft roster is comprehensive for the type - 170 YMS hulls appear with Mine Squadron/Division assignments and named commanding officers, including Colberg sisters YMS-383 (Mine Division 96, Lt. H. C. May USNR), YMS-387 (Mine Division 14, Lt. J. M. Houston USNR), and YMS-388 (Lt. R. E. Crowley USNR), plus adjacent-numbered hulls YMS-389 (Mine Division 94) and YMS-390 (Mine Division 94). YMS-384's absence indicates she was not carried on the Pacific Fleet roster as of that date, though she was at Buckner Bay, Okinawa, by 9 October 1945 - a mid-1945 Pacific arrival consistent with post-V-E-Day redeployment, but her earlier assignment is not documented in located sources.

Adjacent-numbered class sisters YMS-380, -381, and -382 (not Colberg-built) carry European-African-Middle Eastern credits (E5 Normandy, E219 Convoy UGS-38). The absence means no credited campaign participation was recorded for this hull in the awards manual - consistent with her absence from the 1 May 1945 Pacific Fleet roster, though it does not establish where she served.

- Finding
- Class documentation: 'The wood-hulled YMS proved to be one of the U.S. Navy's more durable and versatile types.' 481 of the 136-foot wooden-hull type were built 1942-45 across ~35 yacht yards (19 on the West Coast, including this hull's builder); designed for inshore sweeping ahead of amphibious assaults because wooden construction avoided triggering magnetically activated mines. YMS-135 through YMS-445 (plus 480-481) form the single-stack block to which this hull belongs. Class specification: displacement 320 tons; length 136'; beam 24'6"; max draft 6'1"; complement 33; one 3"/50 dual-purpose mount and two 20mm mounts; two General Motors 8-268A diesel engines, two shafts, 880 designed shp; designed speed 12 knots. The class index notes 'one of their greatest losses being on 9 October 1945, when seven U.S. YMS' were sunk in a typhoon off Okinawa' - the event that destroyed this hull.

The 'seven U.S. YMS sunk' phrasing is class-page summary language; the CinCPac appendix lists only YMS-383 and YMS-384 as 'Sunk' among YMS hulls (others grounded or damaged). No asbestos content.

[10]Era inference built on: NavSource specifications for this hull (2 x General Motors diesels, 2 shafts) and the wooden-hulled YMS-1-class documentation (NavSource class index); GAO HRD-80-2 era documentation (see ev-10) [other_primary]

- Finding type
- asbestos_application
- Finding
- A diesel-powered wooden-hulled minesweeper completed in April 1943 sits inside the Navy's documented asbestos-use era; era-standard applications aboard a small diesel craft of this type were engine and diesel-exhaust lagging, machinery insulation, gaskets, valve packing, electrical insulation, and compartment finishes in the confined hull volume. As a wooden-hulled diesel craft she carried no steam plant and no boiler/turbine lagging - the thermal-insulation application that GAO identifies as the Navy's major asbestos use aboard ships was present at materially smaller scale here than aboard steam vessels, though GAO notes all ships contained asbestos in components such as clutches and electric cables.

- GAO HRD-80-2 product page highlights and 'Navy's policy on use of asbestos' report section
- Finding type
- gov_survey
- Finding
- GAO documented the Navy's shipboard asbestos era: thermal insulation 'was the Navy's major use of asbestos aboard ships'; insulation specifications were changed in 1973 to specify asbestos-free materials, yet 'ships were being delivered with asbestos insulation as late as May 1978'; 'all ships contain some asbestos in such components as clutches and electric cables'; a one-time removal program was rejected on an estimated $2 billion cost. This hull's entire construction (1942-43) and service life (1943-45) falls inside the pre-1973 asbestos-specification era.
