- The NHHC page is indexed with this text but returned HTTP 404 on direct retrieval during this review; the indexed text was checked against NARA's independent service-date index. It gives no asbestos, crew-complement, machinery, or disposal evidence.

- Catalog description, NH 44542

- vessel_history
- Finding
- An NHHC cataloged photograph identifies Henshaw (DD-278) with Moody (DD-277) and Meyer (DD-279) in Dry Dock Number Two at Puget Sound Navy Yard, Bremerton, in September 1922, receiving modified after deckhouses to move the after 4-inch guns farther from the waterline.

- Limitations
- The official NHHC catalog description was available in the search index, but its direct URL failed during review. It documents a yard period and alteration, but does not identify insulation, asbestos, or who performed the work. It occurred after the first decommissioning and before recommissioning.

- Finding type
- historical_record
- Finding
- NARA's shipboard asbestos research guide identifies RG 19 ship engineering drawings, especially S39 insulation and lagging and S48 piping, general information books, and historical ship specifications as records to inspect for a hull-specific materials answer. It states that deck logs and muster rolls do not themselves establish asbestos presence.

- Finding
- GAO's 1979 Navy asbestos report describes asbestos in Navy ship thermal insulation and its 1970s replacement policy. This is later Navy-wide context only; the report's fieldwork concerned Long Beach and Norfolk naval shipyards, decades after Henshaw's final decommissioning.

[8]CourtListener authenticated API v4 search, type=o and type=r, queries "USS Henshaw" and "DD-278" (2026-09-27) [court_record]
- Locator
- Four authenticated search responses; search_ledger sl-uss-henshaw-dd278-06 through -09; seven docket IDs classified in BATCH-3274-REPORT.md
- Finding type
- litigation_documented
- Finding
- Authenticated CourtListener v4 exact-name opinion and docket searches for "USS Henshaw" each returned zero results. The hull-number opinion search for "DD-278" returned zero results. The hull-number docket search returned seven unrelated dockets: two duplicate United States v. Ortega records, Manganiello v. New York City, Food & Water Watch v. EPA, SRI International v. Internet Security, Rohm and Haas v. Honeywell Electronic Materials, and United States v. Brandon Basham. They are unrelated-litigation numeric false positives; no result identifies this vessel or qualifies as DD-278 asbestos litigation.

- Limitations
- This is a search-index negative finding, not proof no case exists. CourtListener coverage is incomplete by nature; no full-text pleading, discovery record, trial finding, or judgment naming DD-278 was located or evaluated. The seven hull-number docket hits are other litigation/numeric collisions, not vessel cases.
