- Finding
- DANFS identifies COLAHAN (DD-658) as a Fletcher-class destroyer with displacement 2,050 tons, length 376 feet 6 inches, beam 39 feet 8 inches, draft 17 feet 9 inches, speed 37 knots, and complement 319. It records Bethlehem Steel Co., Staten Island, as builder; launch on 3 May 1943; commissioning on 23 August 1944 in the page text; Pacific Fleet, Marshall Islands, Guam, Palaus, Leyte, Iwo Jima, Okinawa, and postwar occupation service; decommissioning into reserve on 14 June 1946; recommissioning on 16 December 1950; Korean War and later Seventh Fleet service; and Naval Reserve training through 1963.

- Limitations
- DANFS documents identity, specifications, and service history, not asbestos content, individual exposure, causation, or legal eligibility. The displayed commissioning year conflicts with the official chronology and the stable DANFS mirror, which give 23 August 1943; that correction is recorded separately. The DANFS page does not state a machinery vendor or asbestos application.

- DANFS opening chronology and bracketed closing disposition note
- Finding type
- vessel_history
- Finding
- The DANFS transcription records the corrected construction chronology: COLAHAN was launched 3 May 1943 and commissioned 23 August 1943. It also records that she was struck from the Navy list on 1 August 1966 and sunk as a target off southern California on 18 December 1966.

- Population
- Navy personnel and target-exercise participants; no asbestos exposure conclusion
- Limitations
- The mirror is used for the closing disposition and to resolve the apparent 1944 commissioning typo in the live page; it is a transcription of DANFS rather than a separate contemporary Navy disposition document. It does not document asbestos or the precise wreck location.

[4]Bureau of Ships, Ships' Data, U.S. Naval Vessels 1945, Fletcher-class design section, with NHHC DANFS specifications for COLAHAN [other_primary]
- Locator
- NHHC DANFS specification block; Fletcher-class profile technical block and era evidence
- Finding type
- asbestos_application
- Finding
- Era/class inference only: COLAHAN was a 1943 Fletcher-class destroyer operating a period steam propulsion plant. Fletcher-class design records identify four Babcock & Wilcox boilers, two General Electric geared steam-turbine sets, approximately 60,000 shp, and two shafts; the class and construction era are consistent with period-standard asbestos applications including boiler and steam-line insulation, lagging, gaskets, packing, fireproofing, and deck coverings.

- Fletcher-class construction trades and crews, 1941-1966
- Limitations
- This is class/era context, not a ship-specific finding. Neither the cited class/design material nor the DANFS entry identifies asbestos aboard DD-658, a quantity, a location, remaining material, an abatement event, or any individual's exposure. The Fletcher-class profile is background only and is not being used to upgrade this hull to ship-specific documentation.

- Finding type
- historical_record
- Finding
- No ship-specific asbestos record for USS COLAHAN (DD-658) was located in the public sources reviewed: no hull ACM survey, abatement contract, museum or preservation record, asbestos material specification, or direct government asbestos statement naming this hull was found.

- Limitations
- This is a negative finding about the search result, not proof that asbestos was absent from the ship. Class/era inference remains separate in ev-03. The incomplete CourtListener sweep is not included as support for this negative finding because the helper stood down before returning results; non-indexed state filings, settlements, claims, and unretrieved archival records remain possible.

[6]Authenticated CourtListener helper attempt; exact-name and hull-number searches were initiated through cl-auth-search.py [court_record]

- Finding type
- litigation_documented
- Finding
- The required authenticated sweep was attempted for exact-name and hull-number queries ('USS Colahan' and 'DD-658', opinion and docket types). The helper reported that the fleet-wide paced request budget was momentarily spent and instructed the session not to retry in a loop; no CourtListener result set was returned for classification.

- Limitations
- Because the helper returned a fleet-pacing stand-down before results were delivered, this row establishes a research gap only. It does not support a no-result conclusion and does not classify any litigation hit as qualifying, other litigation, or name collision.
