- Limitations
- DANFS documents identity, service history, and specifications, not materials or asbestos content - the narrative contains no asbestos-related content whatsoever. DANFS states no laid-down date and no striking date for this hull (both carried from consistent secondary compilations - see gaps). Mirror transcription cited because the live NHHC page returns 404 (standing link rot, BATCH-01); a Wayback capture of the canonical NHHC page (2025-02-02) carries identical text.

[2]Navypedia, 'GMT' destroyer escorts (EVARTS) member table and design specifications + DANFS specifications block for DE-261 [other_primary]
- Locator
- navypedia us_de_gmt.htm member table row DE261 Dionne + machinery spec block; DANFS DE-261 spec block ('cl. Evarts')
- Finding type
- asbestos_application
- Finding
- Era/class inference: DE-261 is documented in the GMT (Evarts) member table - Boston Navy Yard, laid down 1/1943, launched 10.3.1943, commissioned 7/1943, stricken 2.1946 - matching DANFS and secondary compilations. The GMT design's machinery is 4 General Motors 16-278A diesel-generator sets with 2 electric motors, 6,000 hp - a diesel-electric plant with no boilers or steam system. A Navy-yard-built diesel-electric escort completed mid-1943 would have carried era-standard asbestos applications appropriate to that plant: exhaust-system insulation, gaskets and packing throughout engineering spaces, electrical insulation, brake linings on winch/windlass equipment, fireproofing, and deck coverings - not boiler or steam-line lagging.

- Limitations
- Class/era inference only - NOT a hull-specific finding. Navypedia is a secondary reference; the DANFS spec block confirms class (Evarts) but does not state engine type. The diesel-electric plant means the largest asbestos categories of steam ships (boiler and steam-line insulation) do not apply. Does not quantify material, does not establish that any specific product was or was not installed aboard this hull, and does not establish any individual's exposure.

- Finding type
- asbestos_application
- Finding
- Contemporaneous U.S. government industrial-health survey of WWII naval ship construction: chest X-ray examinations of 1,074 pipe coverers at two Government Navy Yards and two Navy Contract Yards, with dust counts and material analysis. The survey documents that 'an important ingredient of pipe covering material used on U. S. Navy vessels is amosite' (a fibrous asbestos mineral), and that 'much asbestos cloth and asbestos cement were likewise used' - establishing amosite-asbestos insulation products as frequently employed materials in Navy vessel construction of the era in which this hull was built.

- Limitations
- Era-level government documentation of the material standard in naval ship construction, not a hull record: the surveyed yards are anonymized (Government Yards 'A' and 'B', Contract Yards 'C' and 'D'), so Boston Navy Yard's inclusion cannot be confirmed; the study covers pipe-covering fabrication/installation workers, not ship's crew. Does not establish that amosite or any specific product was installed aboard DE-261, does not quantify, and does not establish any individual's exposure.

- Finding type
- asbestos_application
- Finding
- Builder/repair-yard context: the hull was built at Boston Navy Yard (Atlas yard record 'boston-naval-shipyard', tier 3, with documented asbestos product identification), received repairs at Pearl Harbor in January 1944 ('pearl-harbor-naval-shipyard', tier 1, extensive documented asbestos product list), and underwent a documented overhaul at Mare Island Navy Yard 9 March-8 April 1944 ('mare-island-naval-shipyard', tier 2, extensive documented product list). Yard-level documentation establishes asbestos use at these facilities during the era, not aboard this specific hull.

- Limitations
- Yard-level records only - no yard record names this hull or any hull-specific work order. DANFS documents 'return to Pearl Harbor 12 January 1944 for repairs' and 'overhaul at Mare Island from 9 March to 8 April'; the repair facility at Pearl Harbor is inferred to be the naval shipyard (location named, facility not named). Yard asbestos documentation does not establish that a particular product was installed on or disturbed aboard DE-261.

- Finding
- Archival leads for this hull: NavSource's DE-261 index links a transcription of the ship's official War History submitted at war's end (a primary operational record class held by NARA in the WWII war diaries/ship histories series), and carries U.S. Navy photo captions including 19-21 May 1945 Mare Island overhaul images (e.g., 'She was in overhaul at Mare Island from 16 April until 28 May 1945') - corroborating a second Mare Island availability that DANFS describes only as 'San Francisco and overhaul.' The index also corroborates command dates and the laid-down/stricken dates used in this record.

- Finding
- CourtListener sweep: exact-name query '"USS Dionne"' returned 0 results in the opinion index (type=o) and 0 in RECAP dockets (type=r). Hull-number query '"DE-261"' returned 9 opinion-index hits - all string collisions on manual review (PACER 'DE 261' docket-entry notation, reporter/pin-cite numerals, and a Puerto Rican Spanish-language case; none asbestos-related, none naming a vessel) - and 398 RECAP-docket hits, top-20 reviewed: all non-asbestos federal dockets (employment, criminal, bankruptcy, trademark, contract, admiralty-yacht cases), the 'DE 261' docket-entry notation collision vector; none names this hull. Refinement query 'Dionne asbestos' (type=o) returned 14 hits - all name collisions on review, including one genuinely asbestos-captioned case, Dionne v. ABB, Inc., Del. Super. Ct. N14C-11-062 ASB (2017), in which 'Dionne' is the plaintiff's surname (Clarence Dionne) in Delaware's consolidated asbestos docket; the indexed snippet shows no vessel reference. Remaining hits are person-surname/incidental matches (e.g., Dionne Staples petitioner in Kelly v. HUD; asbestos-captioned Estes v. Eaton Corp. and In re Joint E&S Districts Asbestos Litigation matching 'Dionne' only in body text). No qualifying asbestos litigation naming USS Dionne (DE-261) located.

- Limitations
- Opinion index swept for exact name, hull number, and a 'Dionne asbestos' refinement; docket index swept for exact name and hull number. The 398-hit 'DE-261' docket set was reviewed at top-20 depth only - the collision mechanism ('DE 261' = PACER docket-entry number) is consistent, but un-reviewed hits are not individually excluded. Dionne v. ABB (the sole asbestos-captioned hit) was classified from the indexed caption/snippet - plaintiff-surname collision - without full-text review (fleet pacing budget spent on the fetch); if full text later shows a vessel reference the classification changes. The sweep does not cover state-court records beyond those RECAP-captured, trust claims, or non-U.S. jurisdictions. 'Dionne' is a common surname - future hits need collision classification rather than automatic attribution.

- No qualifying ship-specific asbestos record located for DE-261: no hull ACM survey, no abatement contract, no hazmat disclosure, and no qualifying asbestos litigation naming the vessel. Museum/drydock categories cannot apply because the ship was sold in 1947 and scrapped, and is not preserved. Law-firm/mesothelioma-marketing pages publish templated 'asbestos exposure' content for this hull name/number; reviewed and excluded as non-authoritative advertising content per the hard sourcing rule.

- Absence of a located public record does not prove absence of asbestos aboard during the 1943-1946 commission - era materials aboard a Navy-yard-built escort are plausible (see ev-02, ev-03) but ship-unproven. Does not establish or defeat any claim of exposure or legal eligibility.
