- Limitations
- DANFS documents identity, service history, and the design spec block - it does not document materials, asbestos content, or individual exposure. Entry text predates the 1972 disposal ('where she remains' at Orange, Tex.). The spec block's torpedo-tube count (5) and complement (259) differ from NavSource/class sources - variants carried in gaps. Live hazegray.org was DNS-unresolvable (SERVFAIL on local and public resolvers) at access; transcription captured via the 2021-04-17 Wayback snapshot.

- Construction/disposal data beyond the DANFS narrative: ordered 16 Dec 1940; laid down 30 Jun 1941 (Bethlehem Shipbuilding Corp., San Francisco); decommissioned 1 Feb 1946; stricken 1 Jul 1971. NavSource machinery block: 50,000 shp Bethlehem turbines, 2 screws, 35 kt, crew 208, 2,395 t full load. Disposal: NavSource and NavalCoverMuseum read sunk as a target 28 Jun 1972, 80 miles east of Norfolk at 36 deg 55 min N 74 deg 43 min W in 1,580 fathoms; uboat.net reads 'sunk as a target off the coast of South Carolina 28 June 1972'; Wikipedia/historyofwar read 'disposed of in a fleet exercise 1 June 1972'. NavSource photo captions document the hull nested at the Orange, Texas Inactive Ship Maintenance Facility in 1970 and tied up with YR-26 before being expended as a target in 1971-72.

- Reputable secondary compilations, not primary sources; navsource.org was DNS-unresolvable at access so its data comes from verbatim search-index snippets. The three-way conflict (sink date 1 Jun vs 28 Jun 1972; Norfolk-coordinates vs 'South Carolina' location) is documented in gaps rather than reconciled. None of these sources documents asbestos content.

- asbestos_application
- Finding
- Era/design inference for this hull: a 1941-42 Bethlehem-built Benson-subclass destroyer with four superheated Babcock & Wilcox boilers and ~50,000-shp geared steam turbines would have carried period-standard asbestos boiler and fireroom insulation, steam-pipe and turbine lagging, valve/flange gaskets and packing, accommodation fireproofing, and deck coverings. Builder Bethlehem's San Francisco yard is covered under the Atlas 'bethlehem-shipbuilding' record (tier 3; yard-level evidence centers on the Quincy/Sparrows Point plants). Documented yard periods: Seattle overhaul from 17 Jul 1945 (drydocked; yard unnamed in DANFS) and Charleston inactivation Nov 1945-Feb 1946. NARA RG19 'General Information Books' per-vessel material specifications are an unretrieved archival lead for hull-level specs.

- Limitations
- Class/era and builder-yard inference only - NOT a ship-specific finding; establishes no quantities and no individual exposure. No ship-specific asbestos survey, abatement record, or material inventory was located for DD-610. The Atlas yard record's evidence is weighted to Bethlehem's East Coast yards, not the San Francisco (Union Iron Works) plant. NARA GIB retrieval not performed.

- GAO product page HRD-80-2
- Finding type
- gov_survey
- Finding
- GAO documented that the Navy used asbestos insulation extensively aboard ships, that 1975 standing policy removed asbestos insulation only when damaged or required for repairs (modified 1979 to selective replacement in high-maintenance areas), and that substitution of alternative insulation materials did not begin until the early 1970s - placing DD-610's construction (1941-42), commissioned service (1942-46), and 25-year reserve-fleet custody (1947-71) inside the documented asbestos-use era.

- Ship-specific primary operational records exist at NARA for this hull: at minimum the December 1944 war diary (catalog id 139829837, microfilm serial 104100) in the WWII War Diaries collection at College Park, and the hull's deck logs in NARA custody (DD-610 logs are in the deck-log series). These records document operations, anchorage, and availability periods - the raw material for hull-level yard-period reconstruction - but were not digitized/retrieved in this pass.

A retrieval could support hull-level construction detail (and potentially material/vendor records) unavailable in public sources.

Absence of located litigation does not mean none exists - the hull's wartime era and 1972 sinking predate the asbestos-litigation docket era, and crew claims would more likely appear in veteran-benefit or product-liability channels not indexed here.

- Finding
- No hull-specific asbestos survey, abatement record, materials inventory, hazmat disclosure, or qualifying asbestos litigation located for DD-610 in the sources searched (see search_ledger). The hull never became a museum - the disclosure channel that produced ship-specific records for preserved hulls does not exist - and was expended as a target in June 1972, before SINKEX-era hazmat documentation, after 25 years of reserve-fleet storage at Orange, Texas.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - era-standard applications are documented at class/era level (ev-03) and the GAO documents Navy-wide asbestos insulation use through the period. The hull no longer exists, so present-day ACM status is moot; what was aboard at sinking in 1972 is undocumented.
