- NavSource is a curated volunteer archive, not a government publication; dates and specifications are carried as its transcription of official records. Displacement conflicts with a 320-ton figure in secondary listings (see gaps). Contains no asbestos information. Image caption error on this page documented in ev-uss-yms-169-yms169-04.

- Finding type
- historical_record
- Finding
- Special List 44 records US Navy deck logs for YMS-169 covering 1943-07-10 through 1944-08-26 (RG 24). The window opens ten days after the vessel's documented completion and closes the day she was transferred to France - log coverage dates, not commissioning/decommissioning dates. The logs themselves are the surviving day-by-day record of her US service and are not digitized.

[4]NHHC photograph 80-G-411696, catalog page: 'USS YMS-169. Off the U.S. east coast, circa 1943. Note: acoustic minesweeping "hammer" mounted on her bow.' [other_primary]

- Finding
- NHHC catalogs National Archives photo 80-G-411696 as USS YMS-169 off the U.S. east coast circa 1943, noting an acoustic minesweeping hammer mounted on the bow - contemporaneous official confirmation of the hull's identity and US-service configuration. The image itself shows 'YMS 169' painted on the bow (verified this session via the NavSource-hosted copy, 111916902.jpg).

[5]NavSource YMS-169 page image caption vs. NHHC 80-G-411696 catalog caption and the photograph itself [other_primary]

- Finding type
- historical_record
- Finding
- NavSource's caption text for National Archives photo 80-G-411696 reads 'USS YMS-122', but the same photo is cataloged by NHHC as USS YMS-169 and the print itself shows 'YMS 169' painted on the bow (verified visually this session). The NavSource caption is a labeling error; the photograph is YMS-169.

- Finding type
- historical_record
- Finding
- The 1945 Ships' Data tabulates the YMS type as wood construction (footnote 1), 136'0" length, 24'6" beam, 1,000 shaft horsepower, diesel reduction drive, and lists Dachel Carter S.B. Corp., Benton Harbor, Mich., as builder of sisters YMS-163 through YMS-166 and YMS-170. YMS-169 does not appear in the 1945 US inventory - consistent with her documented transfer to France in August 1944.

- Study period
- 1945 (publication); class data
- Limitations
- Class-level official data: YMS-169 is not named in this volume (she was French property by 1945), so this documents the type and builder, not this hull's individual fittings. The 1,000 shp figure and NavSource's two 880 bhp engine rating measure different quantities and are both carried without reconciliation. No asbestos content.

- Finding type
- asbestos_application
- Finding
- Era/design inference only: as a wood-hulled, diesel-driven auxiliary of WWII US Navy construction, this vessel carried no steam plant and therefore no boiler or steam-line lagging pathway; asbestos applications typical aboard small naval auxiliaries of the era were machinery and exhaust lagging, gaskets, valve packing, electrical insulation, and brake linings.
