[2]Naval War College Archives, NWC collection of photographs, MSC-385, Series I, Sub-Series D, Item 100.9770, USS YMS-449, 1943 Sep 27 [other_primary]

- Finding type
- historical_record
- Finding
- The Naval War College Archives catalogs a photograph titled USS YMS-449 and dates it 27 September 1943, supporting that the designation YMS-449 was in use by that date. This is consistent with the supplied scope correction that the vessel was redesignated before commissioning and did not serve as PCS-1398.

[4]Research log: CourtListener authenticated v4 search via fleet helper, hull-number opinion query YMS-449, limit 20 [other_primary]
- Locator
- CourtListener query YMS-449; type opinion; page 1 of 4 (65 total); request completed 2026-10-04
- Finding type
- historical_record
- Finding
- The authenticated hull-number opinion search for YMS-449 returned 65 mixed results, 20 on the first page. The result set was not fully classified and no qualifying asbestos case has been confirmed. The remaining three required base searches are pending because the fleet-wide helper pacing budget was momentarily spent.

- Limitations
- This is an incomplete litigation sweep and is not a finding that no litigation exists. The 20-result first page was not fully classified in this session; no search variants were run. Complete remaining exact-name opinion, exact-name docket, and hull-number docket searches and classify the full result set when the helper permits.
