- Finding
- Official DANFS record for this hull: DE-576, 1,400 t, 306 ft, complement 186, Buckley class; launched 28 December 1943 by Bethlehem-Hingham Shipyards, Inc., Hingham, Mass., sponsored by Mrs. Cora Dell Barr; commissioned 16 February 1944, Lt.

- Bethlehem-Hingham construction trades 1943-44; wartime crew (design complement 186 plus UDT-13 attachments as APD)
- Limitations
- DANFS documents service history and specifications - not materials or asbestos content. Published before the 1960 striking and 1963 disposal, so postwar disposition comes from secondary sources. Scan contains OCR artifacts ('81 July', '80 June', 'CV E-21'). Does not establish exposure, asbestos presence, or legal eligibility.

[3]Commander Task Group 21.11 (CO USS Block Island), Action Report on the loss by enemy action of USS Block Island, 29 May 1944 + Bureau of Ships War Damage Report No. 49 (NARA-held primary documents; indexed at uboatarchive.net mirror) [other_primary]

- Finding type
- historical_record
- Finding
- Primary-source archival lead: the TG 21.11 action report covers the 29 May 1944 engagement in which this hull was torpedoed, and BuShips War Damage Report No. 49 covers the Block Island loss action; uboatarchive.net also indexes photographs of damage to USS Barr and survivors arriving at Casablanca. These NARA-held records document the combat damage event for this hull at report level.

- Limitations
- Index-level verification only - the action report and damage report are NARA records mirrored by a private site; full-text review of the damage-report sections specific to Barr not performed. Combat-damage documentation, not asbestos documentation; establishes nothing about materials aboard.

[4]Bureau of Ships, Ships' Data U.S. Naval Vessels Vol. 1 (Jan 1945), DE design-group table (groups 2-3, TE turbo-electric) + navypedia Buckley (TE) member table boiler-block map [other_primary]
- Locator
- SDB1945v1 pp. 234-235 design-group table; navypedia us_de_te block map; Atlas class profile buckley-class
- Finding type
- asbestos_application
- Finding
- Class/era inference: the Buckley TE design (BuShips design groups 2-3) ran 2 'D' express-type boilers at 435 psi/750 deg F superheat feeding GE turbo-electric machinery, 12,000 shp, 2 shafts; navypedia's block map assigns Foster Wheeler boilers to the DE 563-578 block containing this hull. A 1943-44 steam-plant combatant of this type would have carried era-standard asbestos insulation on boilers, steam lines, and machinery (lagging, gaskets, packing, fireproofing, deck coverings). Boston Navy Yard performed the 1944 battle-damage repair and APD conversion on this hull; Boston Navy Yard is a documented asbestos-exposure yard at yard level.

- Limitations
- Class/era and builder-yard inference only - no ship-specific finding. Boiler-manufacturer block map is navypedia-sourced, unverified against contract documents. BuShips table does not name this hull. Does not establish that asbestos products were installed on this hull, quantities, or any exposure outcome.

- Finding
- No qualifying ship-specific asbestos record located for this hull: no asbestos survey, abatement contract, shipyard hazmat disclosure, environmental record, or docketed asbestos litigation naming USS Barr (DE-576/APD-39) was found in the public sources searched (see search_ledger). The hull's disposition (sunk as a target off Vieques Island, 1963) forecloses museum-era survey or in-service abatement documentation.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a 1943-44 steam-plant combatant was era-typical for asbestos use, and the 1963 sinking pre-dates abatement regulation. Does not establish that asbestos is or was present aboard, does not establish or defeat any claim of exposure or legal eligibility.

- Finding
- Litigation sweep result: NO qualifying asbestos litigation naming this hull located. Opinion index: '"USS Barr"' 0 results; '"U.S.S. Barr"' 0 results; '"APD-39"' 0 results; '"DE-576"' 8 hits, all reviewed and classified as name collisions (Chiquita MDL, Medical Assurance v. Weinberger, Sutton v. St. Jude Medical, Pueblo v. Vales Aviles, Western Constructors v. Southern Pacific, Walgreens PR v. Secretaria de Salud, Acheson v. Albert, ABB Power v. Gothaer - 'DE 576' token matches to docket-entry/reporter strings, no vessel reference). RECAP docket index: '"USS Barr" asbestos' 0 results. 'Barr' is a high-collision name (surname, place names); every hit was hull-attribution reviewed before classification.

- Limitations
- Sweep coverage limited to CourtListener indexes via the fleet-authenticated helper; PACER-only dockets and state-court filings outside CL coverage are not swept. The '"DE-576"' RECAP docket query was blocked by shared fleet pacing after 4 spaced attempts - hull-number docket coverage is a residual gap, though vessel-name docket text was swept clean. A null result does not prove no litigation exists - it establishes no qualifying indexed record was located on this date.
