- Population
- Bath Iron Works construction trades 1943; wartime and postwar crew (DANFS complement 345); reserve-training nucleus crew and reservists 1965-68
- Limitations
- DANFS documents service history and specifications, not materials or asbestos content. Two DANFS versions were used: the original-volume entry (ibiblio/HyperWar transcription) and the extended entry (destroyerhistory.org transcription); minor conflicts between them are carried in gaps. Sinking location 'off Virginia' is from secondary indices (NavSource, Wikipedia) - DANFS gives only 'sunk as a target on 8 October 1969'. Repair facilities at Norfolk (1952-53), Boston (1944), and the 1968 inactivation site are not named in DANFS.

- Official dose-reconstruction technical report carries a dedicated section for this hull: USS Barton (DD-722), crew size 260, Surface Patrol Group; departed Pearl Harbor 8 June 1946, arrived Bikini 15 June via Kwajalein; special oceanographic and radiological equipment installed for survey-ship duty; observed Shot ABLE from ~11.7-15 miles (1 July) and Shot BAKER from ~8-10 miles (25 July); conducted lagoon radiological soundings and patrols; departed Bikini 10 August 1946; total calculated film-badge dose received while at Bikini 0.519 rem; ship contamination factor 13 at departure.

- Limitations
- Ship-specific official record of a radiological exposure event, not an asbestos record - included as an exposure-relevant government record only; establishes nothing about asbestos aboard this hull. OCR-derived transcription (exa.ai mirror of the report text); dose figures are reconstructed estimates, not measured film badges. Report's post-Bikini itinerary (San Francisco via Pearl Harbor) differs from DANFS's (San Diego) - carried in gaps.

- Finding type

- Finding
- Era/yard inference: a Sumner-class destroyer built at Bath Iron Works in 1943 with a four-boiler steam plant would have carried period-standard asbestos insulation, lagging, gaskets, packing, and fireproofing; builder Bath Iron Works is documented at yard level in the Atlas dataset (tier 2), including the 1942 Harvard/Drinker industrial-hygiene study recording 'fairly serious dust risk' at roughly ten times the safe threshold in pipe-covering shops (PMID 21016030); NARA RG 19 'General Information Books' holding per-vessel material specifications are an archival lead for hull-level specs.

- Finding type
- gov_survey
- Finding
- GAO documented the Navy's extensive shipboard asbestos insulation use with substitution not beginning until the early 1970s - Barton's construction (1943) and entire service life (to 1968) fall inside the documented asbestos-use era, as do her 1952-53 mine-damage reconstruction and 1955 overhaul.

- Finding
- CourtListener API v4 authenticated sweep for this hull (2026-09-27), all queries completed after waiting out fleet pacing: 'USS Barton' exact-name queries returned zero hits in both the opinion and docket indexes - no published opinion or indexed docket names a 'USS Barton'. 'DD-722' opinion query returned zero hits; 'DD-722' docket query returned 5 hits, all name collisions resolved by inspection - Sokolow v. Palestine Liberation Org., No. 04-cv-00397 (S.D.N.Y.) (exhibit document identifier), Garibay v. Marshall (N.D. Cal. habeas), Hicks v. Jenne (S.D. Fla. prisoner civil rights), Vazquez v. Gonzales (D.D.C. habeas), Allstate Insurance Co. v. Medaid Radiology LLC, No. 20-cv-01108 (S.D.N.Y.) (insurance/remand) - none naming the vessel. No qualifying asbestos litigation naming this hull was located.

- Limitations
- CourtListener indexes cover published opinions and federal dockets - unindexed state-court filings, settled MDL-875 claimant records, and non-digitized proceedings are outside coverage; no search can prove the absence of all possible litigation. Name-collision note: two Navy ships carried 'USS Barton' - DD-599 (sunk 13 November 1942) and this hull (DD-722, in commission 1943-1968); any 'USS Barton' exposure claim with postwar dates almost certainly refers to this hull, while 'Barton' alone is a high-collision surname (and a NY garnet-mining defendant name). Per batch discipline a pleading-stage reference would classify as allegation, not adjudicated exposure.

- historical_record
- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, material inventory, museum hazmat disclosure, or docketed asbestos case naming DD-722 was found in the public sources searched (see search_ledger). The hull was sunk as a target in 1969, before routine hazmat documentation of disposal.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - era and class inference support asbestos presence but it is not ship-proven. Does not establish or defeat any claim of exposure or legal eligibility. Whether the hull was stripped of hazardous material before the 1969 target sinking is undocumented.
