- PC-622 milestone paragraph and specifications block
- Finding type
- vessel_history
- Finding
- The ship-specific page records PC-622 as a PC-461-class submarine chaser laid down 22 May 1942 by Nashville Bridge Co., Nashville, Tennessee; launched 7 July 1942; commissioned 9 March 1943; presented to the Kingdom of Greece on 10 June 1943 at Washington Navy Yard and named Vassilefs Georghios II (P 17); struck from the Navy Register in 1963 and scrapped. It lists 65 personnel, two 1,440-bhp General Motors 16-258S diesel engines, two shafts, and the PC-461-class dimensions and armament.

- Nashville Bridge construction trades; U.S. Navy crew in 1943; Greek Navy crew after transfer
- Limitations
- Ship-specific identity and milestone compilation, not a Navy registry or materials survey. The page does not document asbestos, individual exposure, quantities, or the exact Greek decommissioning/disposal sequence. It states 'scrapped' but does not identify a date or yard.

- Finding
- NARA's ship-number logbook index includes PC-622 with coverage from 9 March 1943 through 10 June 1943, matching the U.S. commission date and the date of transfer to Greece recorded by the ship-specific page.

- Finding type
- vessel_history
- Finding
- No live NHHC DANFS entry for PC-622 was located at the canonical ship-history URL checked on 2026-10-03; the ship-specific compilation page explicitly states that no DANFS history is available for PC-622.

- Limitations
- A missing DANFS entry is an access/catalogue finding, not evidence that no official historical record exists and not evidence about asbestos. NARA's logbook index remains an archival lead, and the NavSource page supplies the accessible ship-specific milestone record.

[5]U.S. General Accounting Office, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (18 October 1979) [gao]
- Locator
- GAO product page HRD-80-2; Navy shipboard-use and policy sections
- Finding type
- asbestos_application
- Finding
- The GAO review reports Navy-wide shipboard asbestos use, including thermal insulation as the major use and asbestos in components such as clutches and electric cables, and discusses the Navy's October 1975 policy to eliminate asbestos as an acceptable thermal-insulation material. This provides era context for a vessel constructed and commissioned in 1942-43.

- Population
- Navy ships and shipyard workers in the GAO review; era context for PC-622
- Limitations
- Program-level evidence, not a PC-622 finding. It does not identify materials installed aboard this hull, quantify asbestos, establish remaining material, or prove exposure. Automated live retrieval of the GAO page was unavailable; the report's established fleet research summary is used as an access-disclosed context lead.

[6]Era inference from the PC-622 ship-specific propulsion record, PC-461-class Navy tabulation, and GAO HRD-80-2 [other_primary]
- Locator
- NavSource PC-622 propulsion block; GAO HRD-80-2; PC-461-class context
- Finding type
- asbestos_application
- Finding
- A steel PC-461-class submarine chaser built in 1942 and commissioned in 1943 falls within the documented Navy asbestos-use era. For a small all-diesel craft, the bounded era pathways are engine or exhaust insulation/lagging, gaskets, valve and flange packing, electrical insulation or cable covering, and compartment insulation where fitted; the ship-specific propulsion record shows no steam plant, so boiler and turbine lagging cannot be inferred for PC-622.

- Limitations
- Class/era inference only. No hull-specific insulation survey, material list, construction specification, repair package, abatement record, manufacturer, quantity, or exposure testimony was located. These are possible period applications, not confirmed PC-622 installations.

[7]Authenticated CourtListener helper sweep: four required base searches attempted; helper pacing stand-down prevented result retrieval [court_record]

- Finding type
- litigation_documented
- Finding
- The required exact-name opinion, exact-name docket, hull-number opinion, and hull-number docket searches were each attempted through the authenticated helper with a 20-result limit. Each returned the fleet-wide pacing message before data retrieval; therefore no litigation result was classified and no asbestos-qualified variant was run.

- CourtListener opinions and RECAP dockets indexed through the helper
- Limitations
- This is a blocked search, not a no-result finding. No conclusion about the presence or absence of asbestos litigation may be drawn. The helper instructed a stand-down because the shared fleet request budget was momentarily spent; retrying was not permitted under the batch rules.
