- Finding
- DANFS record for this hull: Benson class; launched 12 February 1942 by Bethlehem Shipbuilding Co., Inc., San Francisco, Calif., sponsored by Mrs. G. Coghlan; commissioned 10 July 1942, Lt. Comdr.

- Limitations
- DANFS documents service history and specifications, not materials or asbestos content. Omits the keel-laying date entirely (secondary consensus reads 28 March 1941 - carried in gaps). Reads 'Chicago Harbor' and 'Amchatka' - apparent misprints for Chichagof Harbor (Attu) and Amchitka, quoted verbatim rather than silently corrected. Mirror transcription cited because the live NHHC DANFS page returns 404.

[3]NARA Catalog, Record Group 24 deck logs for USS Coghlan (DD-606), digitized monthly file units, National Archives at College Park (scans via NOAA) [other_primary]

- Finding type
- historical_record
- Finding
- NARA holds digitized deck logs for this hull as monthly file units in RG 24 (Logs of U.S. Naval Ships and Stations), scanned to JPG in the National Archives Catalog - example: 'Coghlan (DD-606), May 1944' (naId 17291555, 110 page images). Catalog search returned ~294 file units for the hull, with dated coverage observed September 1942 through mid-1946. Deck logs record positions, operations, personnel musters, and yard availabilities - a primary channel for verifying a claimed service window aboard this hull.

- Finding type
- historical_record
- Finding
- NARA holds this hull's monthly WWII war diaries as cataloged file units - observed units span December 1942 through September 1945 (e.g., naId 134075186 for Dec 1942; 139967362 Mar 1945; 77530061 Sep 1945). War diaries are the ship's own submitted operational narratives and can corroborate combat-period movements and overhaul availabilities independent of DANFS.

- Finding type
- asbestos_application
- Finding
- Era/design inference for this hull: DD-606 is a Benson-subclass unit of the class BuShips groups under 'No. 421 Class' - 4 Babcock & Wilcox superheated boilers (575 psi / 700 deg F per the 1945 machinery table) driving geared turbines at ~47,000-50,000 shp, built 1941-42 squarely in the Navy's peak asbestos-insulation era. Period-standard asbestos applications for a steam destroyer of this design: boiler casing and fireroom insulation, steam-pipe and turbine lagging, valve/flange gaskets and packing, deck tile, and accommodation insulation.

- Limitations
- Class/era inference only - Ships' Data contains machinery specifications, not insulation-material schedules, and does not name DD-606 in any asbestos context. The image-only scan could not be OCR'd to a reliable per-hull row this session; class-level table data carried from the fleet's prior extraction. Establishes no quantities and no exposure for any individual.

- Locator
- GAO product page HRD-80-2
- Finding type
- gov_survey
- Finding
- GAO documented the Navy's standing asbestos-protection policy: as of 1975 the Navy removed asbestos insulation aboard ships only when damaged or required for repairs, modified 1979 to selective replacement in high-maintenance areas - i.e., original-era insulation typically remained in place for decades unless a yard period disturbed it. Context for this hull's documented overhaul record (San Francisco 1943, Pearl Harbor 1944 x2, stateside 1945, Charleston 1945-47) and reserve-fleet layup.

- Finding type
- litigation_documented
- Finding
- CourtListener searches located no qualifying asbestos litigation naming this hull: "USS Coghlan" (type=o) returned 0 hits; the bare surname "Coghlan" returns name-collision cases only (e.g., Coghlan v. Aquasport Marine Corp., 73 F. Supp. 2d 769 (S.D. Tex. 1999) - a recreational-boat class action; Bennett v. Kelly Coghlan - a Texas legal-malpractice mandate). Hull-number and docket-level queries were throttled by fleet rate limiting before completion (see search_ledger sl-08).

- Limitations
- Sweep limited to CourtListener's indexed opinion and RECAP docket text; un-indexed dockets, state-court filings, and non-digitized records are outside coverage. Fleet rate limiting truncated the sweep - the "Coghlan" opinion result set was reviewed only in part, and DD-606/docket queries did not complete; absence of a located case does not prove none exists. Re-sweep queued in sl-08.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, product-identification record, or docketed asbestos case naming USS Coghlan (DD-606) was found in the public sources searched (see search_ledger). The hull was sold for scrap in 1974, foreclosing any present-day survey or museum-disclosure channel.

- Absence of a located public record does not prove absence of asbestos aboard - a 1941-42 steam destroyer is era-consistent with extensive ACM, and ship-breaker records (1974) were not located. Does not establish or defeat any claim of exposure or legal eligibility.

- Locator
- nvr.navy.mil SHIPSDETAIL_DD_606 page + NVR coverage note
- Finding type
- vessel_history
- Finding
- NVR carries no ship-specific record for DD-606: the detail URL resolves to the generic NVR inventory page, which states 'ships and service craft disposed of prior to 1987 are currently not included.' This hull was stricken 1 July 1971 and sold 12 June 1974, i.e., disposed before the coverage cutoff - the absent record is expected, not an anomaly.
