[2]Fletcher-class machinery data (4 B&W boilers, 2-shaft GE turbines; NPS NHL nomination for class member USS Kidd DD-661, NRHP 83000502) + Atlas shipyard dataset, Federal Shipbuilding-Kearny record (incl. Owens-Illinois industrial-health survey of the yard, Aug. 30 - Sep. 2, 1944) [other_primary]

- Finding type
- asbestos_application
- Finding
- Era/yard inference: a WWII Fletcher-class destroyer with a four-boiler/60,000-shp steam plant would have carried period-standard asbestos insulation, lagging, gaskets, packing, and fireproofing; the builder yard (Federal Shipbuilding & Drydock, Kearny, NJ) is documented at yard level in the Atlas dataset - including a 1944 Owens-Illinois industrial-health survey recording Johns-Manville Superex pipe covering and boiler-insulation work in confined spaces at the yard.

- Limitations
- Class/era and builder-yard inference only - NOT a hull-specific finding. The 1944 yard survey (Aug. 30-Sep. 2, 1944) postdates this hull's December 1942 launch and January 1943 commissioning and documents yard practice, not materials aboard DD-502. Does not quantify material or establish any individual's exposure.

- Finding type
- gov_survey
- Finding
- GAO documented that the Navy used asbestos insulation extensively aboard ships and did not begin substituting alternative insulation materials until the early 1970s - placing this hull's construction (1942-43) and entire commissioned service (1943-1947) inside the documented asbestos-use era.

- Secondary compilation for this hull: records the 31 July 1975 sale to 'Consolidated Steel, Brownsville, TX and broken up for scrap'; '23 of her crew were lost' (the 14 April 1945 kamikaze toll not stated in DANFS); photo captions document the November-December 1944 overhaul as Bethlehem Steel, San Francisco (Pier 54 berth with Ringgold and Shea, NARA photo 19N80477) and place the decommissioned hull at the Philadelphia inactive ship facility in 1970, 'one of the very last WWII configurations left in the yard in 1974.'

- Limitations
- NavSource is a volunteer-compiled secondary source - used for the disposal buyer, casualty figure, and yard-period detail because DANFS does not state them; consistent with DANFS on all overlapping dates except laid-down (NavSource reads 22 June 1942 vs. DANFS 22 July 1942 - carried in gaps). No asbestos content documented. Accessed via Wayback capture 2025-05-29; live site unreachable from this session.

[5]CourtListener API v4 exact-name and scoped searches: '"USS Sigsbee"' (opinions: 0; RECAP dockets: 0); 'Sigsbee' (opinions: 287 results - sampled top hits all surname/entity collisions: People v. Sigsbee, Sigsbee Holding Corp. v. Leventhal, Sigsbee v. State, etc.); 'Sigsbee asbestos' (opinions: 1 result - Amcast Industrial Corp. v. Detrex Corp., N.D. Ind. 1991, environmental-coverage litigation, no vessel connection apparent from indexed text); '"DD-502"' (opinions: 0) [court_record]

- Finding type
- litigation_documented
- Finding
- No qualifying asbestos litigation naming USS Sigsbee (DD-502) located in CourtListener. Exact-name searches return zero at both opinion and RECAP docket level; the hull-number opinion query returns zero. The bare-surname sweep returns person-name collisions only (Sigsbee is a recurring surname in NY/IL/AL case reports since the 1870s); the single asbestos-scoped hit (Amcast v. Detrex, N.D. Ind. 1991) is an environmental insurance-coverage case with no identified ship connection.

- Limitations
- A loose '"DD-502"'-in-docket variant remained pending at record close (fleet-paced API budget); given zero exact-name docket hits, residual risk is low but not zero - an unindexed pleading or docket reference naming the hull cannot be excluded. Absence of a located case is not proof that no claim was ever filed.

- No qualifying ship-specific asbestos record located for DD-502: no hull ACM survey, no abatement or hazmat record, no materials inventory, no museum disclosure (hull scrapped 1975-76), and no qualifying asbestos litigation naming this hull in the opinion sweep. BuShips War Damage Report No. 51 (destroyer gunfire/bomb/kamikaze damage, 1947) was checked and contains no dedicated Sigsbee case section.

- Absence of a located public record does not prove absence of asbestos aboard - era-standard applications are documented at class/era level (ev-02). NARA RG 19 per-vessel material specifications (General Information Books) remain an unretrieved archival lead. Does not establish or defeat any claim of exposure or legal eligibility.
