Vanderbilt three days later. Convoy to Guadalcanal 26 July - 16 August 1943; swept mines off Kolombangara Island 23 October - 6 November 1943; escort/patrol in Solomons, New Hebrides, New Caledonia (Auckland voyage escorting Delphinius (AF-24) 16 January - 1 February 1944) until end of war.

- Compiled record for this hull: laid down 6 April 1942 by Commercial Iron Works, Portland, OR (yard hull no. 40 per shipbuilding tabulations); Adroit-class steel minesweeper, 295 t, 173'8" length, 23' beam; armament one 3"/50 dual-purpose mount, one 40mm, five 20mm, two depth-charge tracks, two depth-charge projectors; propulsion two Cooper Bessemer GNB8 diesel engines (900 hp each per NavSource), Farrel-Birmingham single-reduction gear, two shafts; complement 65 (minesweeper) / 105 (as PC-1592, HyperWar). Reclassified PC-1592 1 June 1944 along with the entire Adroit class (AM-82 through AM-99 -> PC-1586 through PC-1603). Seven USNR commanding officers listed, October 1942 - May 1946.

[3]DANFS construction record for this hull (1942 Navy build) + documented propulsion plant (diesel, twin screws) - basis for era-level asbestos-materials inference [nhhc_danfs]

- Finding type
- asbestos_application
- Finding
- As built in 1942 under wartime Navy specifications, a steel-hulled diesel minesweeper of this type carried era-standard asbestos applications: thermal lagging on diesel exhaust manifolds and mufflers; gaskets and packing throughout the engineering plant; asbestos-containing electrical insulation and switchboard arc protection; thermal/acoustic insulation in machinery spaces and accommodation areas; deck coverings and cements; and asbestos brake linings on winch, windlass, and minesweeping-gear machinery.

- Limitations
- Era inference, not a hull record: no insulation survey, specification schedule, or materials list for this hull was located. Because the plant is diesel (no boilers, no steam system), boiler and steam-line insulation claims made for steam vessels do NOT apply here and are excluded. Does not establish quantity, specific products, present-day presence, or any individual exposure.

- NARA holds deck logs and small-format patrol logs for WWII-era vessels in the 1941-1959 series. The NAC digitized listing for 'Dash' covers only Dash (AM/MSO-428), 1956-1973 - the second, later vessel of the name. Deck logs/patrol logs for AM-88/PC-1592 (1942-1946) should exist in the 1941-1959 series but digitization for this hull is not confirmed; WWII war diaries (RG 38) are a parallel lead.

- Disambiguation: a second USS Dash (AM-428/MSO-428), an Agile-class ocean minesweeper built at Astoria, Oregon, served 1953-1982 and was scrapped in 1984. Any 'USS Dash' record dated 1953 or later, any MSO-428 reference, and the digitized NARA deck logs under 'Dash' (1956-1973) belong to that later hull - not to AM-88/PC-1592.

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or docketed case naming USS Dash (AM-88) or PC-1592 was found in the sources searched. CourtListener API returned HTTP 429 (shared daily quota exhausted); name/hull searches completed via the public web index returned only unrelated 'Dash' name collisions (e.g., Damon Dash entertainment litigation). No result does not equal no exposure - it means no public record was located.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - the hull's 1942 wartime construction is itself consistent with era-typical materials. Does not establish that asbestos is or is not present, does not establish or defeat any claim of exposure or legal eligibility, and the API-throttled CourtListener check should be re-run when quota resets.
