- Finding
- Contemporaneous official action report for this hull: at the time of the 7 December 1941 raid Conyngham was moored starboard side to the tender USS Whitney at berth X-8, with Reid, Tucker, Case, and Selfridge nested outboard, 'undergoing routine tender overhaul with all main engines, boilers and generators disabled. Power was being received from the tender.' General quarters at 0755; opened fire with 5-inch guns and machine guns at 0808; attacking planes shot down by combined nest fire at 0813, 0826, 0830, and 0908; damage limited to a .30-caliber bullet that glanced off the fire-control platform and minor rangefinder-cover rupture; no personnel casualties; ammunition expended 114 rounds 5"/38 and 2,500 rounds .50 caliber; work to recommission the engineering plant began 'immediately upon commencement of the raid' and the ship got underway at 1714.

Held general quarters, manned all guns, commenced breaking out powder. Commenced emergency repairs on main engines to get underway. Captain on the bridge.' Followed by the 8-12 watch firing record matching the action report. Confirms the hull's log survives in the National Archives deck-log series and corroborates the action-report sequence (emergency work on the disabled main engines to get underway).

Photo captions document the twin launching with USS Case (DD-370) at the Boston Navy Yard (caption misprints 'September 1934' - launch was 1935, see gaps) and the ship off the Mare Island Navy Yard 22 January (1942 overhaul period).

- Finding
- Era/yard inference: a Mahan-class destroyer built 1934-36 with a four-boiler high-pressure geared-turbine steam plant (4 Foster Wheeler boilers, 465 psi/645 deg F; GE geared turbines; 50,000 shp design; 2 shafts; 36.5 kt - 'a new generation of destroyer machinery' combining higher pressure/temperature with lightweight fast-running turbines) would have carried period-standard asbestos insulation - boiler and steam-line lagging, gaskets, packing, magnesia-type block insulation, and fireproofing, which were commonly asbestos-containing in treaty-era naval construction. Builder Boston Navy Yard is documented at yard level in the Atlas dataset (tier 3: litigation product ID for John Crane gaskets/sealing materials at the yard). Documented repair/overhaul yards on this hull's record (Mare Island early-1942 overhaul; Pearl Harbor November 1942 collision repair and 1940-41 base operations; Subic Bay 1945 - not in dataset) are Atlas-listed yards with era asbestos documentation (Mare Island tier 2 product list; Pearl Harbor tier 1 cohort SMR, PMID 4016758).

Destroyer History Foundation is a reputable secondary source citing the Mahan/Cummings BuC&R General Information Book; that GIB (NARA RG19) is the archival lead for hull-level material specifications and is unretrieved.

- Finding
- Ship-specific archival holdings exist for this hull at NARA, and NARA publishes a research guide naming the exact record series that could establish hull-level asbestos documentation: RG19 General Information Books (Entry P 9) and ship engineering drawings filed by hull number, which can include insulation-and-lagging ('S39'-type) sheets; BuShips correspondence files are indexed by hull designation ('DD371'). Located for this hull: (1) RG19 engineering-drawings file unit 'Plans for the Destroyer USS Conyngham (DD-371)' - the digitized portion is a General Arrangement set dated 2 August 1938 (cover, inboard profiles; one sheet revised/dated 22 January 1942, the Mare Island overhaul period), downloaded from NARA and re-hosted on archive.org. (2) WWII deck logs - the December 1941 Conyngham log is quoted in NARA's own Prologue article (ev-03). (3) The Mahan/Cummings BuC&R General Information Book cited by Destroyer History Foundation.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or docketed asbestos case naming USS Conyngham or DD-371 as an exposure site was found in the public sources searched (see search_ledger). The hull was scuttled in July 1948 - decades before the asbestos-litigation era - so no preserved-hull, museum-disclosure, or veteran-plaintiff litigation surface exists; the 1936-46 shipboard population is the entire exposure-relevant cohort. Completed CourtListener sweeps: 'USS Conyngham' opinions = 0; '"Conyngham" asbestos' opinions = 2, both name collisions (Commonwealth v. Muniz, Pa. 2017 - a William Joseph Conyngham appears as amicus attorney; Citizens Electric Corp. v. Giles Armature, S.D. Ill. 1995 - caption/attorney collision); 'DD-371' opinions = 1 (Northern Assur. Co. v. Gross, Tex. App. 1927 - serial/docket-text collision, predates the hull); 'USS Conyngham' RECAP dockets = 8, all non-qualifying - the string sits inside indexed attachments (reused 103-page CBS Corp. 'Master Exhibit List' documents in W.D. Wash. asbestos cases Yoder 2:14-cv-00006, Holck 3:13-cv-05905, McCrossin 3:14-cv-05382; exhibit-bearing memos in Laughlin 4:18-cv-00132 E.D.

Va. marine; plus non-asbestos dockets Skelton 3:10-cv-01958 veteran-benefits and Di Liscia 1:21-cv-01047 civil rights) - none is an exposure-site allegation, and asbestos-era 'USS Conyngham' references are more plausibly DDG-17 (1963-1990) than DD-371 (sunk 1948); 'DD-371' RECAP dockets = 16, all document/serial collisions in unrelated patent, bankruptcy, contract, and civil-rights dockets.

- Absence of a located public record does not prove absence of asbestos aboard - treaty-era steam-ship construction commonly used asbestos, but for this hull that remains era inference, not ship-proven. Does not establish or defeat any claim of exposure or legal eligibility. The eight RECAP 'USS Conyngham' hits were classified from docket metadata and snippet context without opening the underlying PDFs (fleet pacing budget); the vessel's role inside those attachments is unresolved and hull attribution (DD-371 vs. DDG-17) is unresolved - classified at the less-final stage accordingly. CourtListener coverage completed 2026-09-27 after fleet-pacing stand-downs.
