- Study period

- Population
- Luders Marine construction trades (1943-44); wartime crew (1944-46)
- Limitations
- Vessel history and specifications only - no asbestos or material content. NavSource is a volunteer secondary compilation, not a primary registry; no independent primary source (DANFS, NVR) was locatable to cross-check these dates against, so they are carried as the best-available record. No decommissioning date distinct from the 1946 strike date is given.

- Finding
- Corroborates builder (Luders Marine Construction Co., Stamford, CT), class (PC-461), and milestone dates (ordered 6 March 1942; laid down 2 August 1943; launched 21 November 1943; commissioned 1 July 1944) independently of navsource.net. Adds a wartime commanding-officer sequence: Lt. R. J. Kirkland Jr., USNR (July 1944-mid 1945); Lt. T. W. White, USNR (mid 1945-mid/late 1945); Lt. H. F. Johnson, USNR (mid/late 1945-2 January 1946). Page notes its service-history section is still in preparation and gives no specifications or disposal data.

- Finding type
- gov_survey
- Finding
- GAO documented that the Navy used asbestos insulation extensively aboard ships fleet-wide and did not begin substituting alternative insulation materials until the early 1970s - spanning this hull's entire construction (1943-44) and commissioned service (1944-46).

[5]Era inference built on: navsource.net/uboat.net specifications (diesel propulsion, no steam plant) and GAO HRD-80-2 fleet-wide asbestos-use/substitution timeline (ev-03); no yard-specific industrial-hygiene study exists for builder Luders Marine Construction Co. [other_primary]

- Finding type
- asbestos_application
- Finding
- A diesel-powered PC-461-class submarine chaser built 1943-44 sits inside the Navy's documented fleet-wide asbestos-use era (GAO HRD-80-2). As a diesel vessel with no steam plant, the boiler/turbine lagging pathway of steam-powered ships does not apply; era-standard applications on a small diesel patrol craft of this type and period would instead be engine- and exhaust-lagging, gaskets, valve packing, electrical insulation, and deck covering in the confined hull volume.

(unlike major Navy-contract yards such as Electric Boat). Names era-standard categories, not confirmed installed materials. No quantity, no manufacturer attribution.

- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos record located: no DANFS entry exists for PC-1219 (NHHC does not maintain a named-ship history page for most hull-numbered PC-461-class craft); the Naval Vessel Register has no digitized record for a hull struck in 1946 (pre-dates NVR's post-1987 digitization scope, and the live site now sits behind a Navy SSO login wall - access blocked, not confirmed absent); no National Archives catalog record was located for this hull; no NIOSH Health Hazard Evaluation exists for builder Luders Marine Construction Co.; and no asbestos survey, abatement record, or hazmat disclosure of any kind was found in the public sources searched. CAVEAT: CourtListener could not be queried this session - both attempts returned the fleet-wide shared-quota pacing message; logged as blocked in search_ledger, not as a negative result. Secondary web sweeps (general web search for "PC-1219" + asbestos/litigation/mesothelioma) surfaced no qualifying case and no law-firm marketing content specific to this hull either.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard, and the litigation-repository search is a genuine open gap (throttled, not completed). NARA RG 24 deck logs and any Luders Marine Construction Co. yard records are undigitized leads not ruled out.
