- Limitations
- NavSource is a volunteer secondary compilation, not a primary registry - but it is the standard reference for numbered patrol craft (no DANFS entry exists for this hull, stated on the page itself). Documents milestones and specifications, not materials or asbestos content. French-service detail is limited to the transfer, name, and disposal lines.

- Finding
- The builder's production table lists this hull: 'PC 562 | US Navy | Sub Chaser | 463d | 173 | 5-Aug-42 | To Free French 1944 as L'Attentif (W 21), sunk as target 1953' - corroborating builder, delivery date (5 August 1942, matching the NavSource commissioning date), 1944 Free French transfer, and 1953 target sinking. Yard history: Jeffersonville Boat & Machine Company, known as JeffBoat, organized 1938 by American Barge Line on the site of the former M. A. Sweeney & Brothers yard; a major wartime LST builder with employment peaking near 13,000; closed permanently 2018. The same table lists sister chasers PC 559-561 and PC 624-627 built at JeffBoat.

- Limitations
- Secondary industry reference (private compilation), not an official registry. Two discrepancies vs NavSource are carried in gaps: pennant 'W 21' here vs 'W 63' elsewhere, and 463d/173 ft vs NavSource's 280-295 t/175 ft. Yard-history narrative used for builder context only; contains no asbestos content and no material records.

- Finding
- uboat.net record for this hull: ordered 1 April 1941; built Jeffersonville Boat and Machine Co.; laid down 13 February 1942, launched 4 June 1942, commissioned 5 August 1942, end of U.S. service 30 June 1944 (transferred to France, renamed 'L'Attentie' [sic]). Commanding officers: Lt. Stanley H. Johnson, USNR (5 Aug 1942 - early 1943); Ens. Arthur D. Berliss Jr., USNR (early 1943 - 8 Aug 1943); Dan W. Ryan, USNR (8 Aug 1943 - 30 Jun 1944). Notable event: PC-562 (Lt. S.H. Johnson) joined convoy TAG 33 / renumbered GN 33 on or about 5 January 1943, escorting it toward New York alongside USS Dickerson, USS Temptress, USCGC Triton, and USS PC-619 - establishing Caribbean/Atlantic convoy-escort employment before her Mediterranean deployment.

Wikipedia's List of escorteurs of France likewise lists Attentif (ex-USS PC-562).

[6]Era inference built on: NavSource specifications (two GM 16-258S diesels, Farrel-Birmingham reduction gear, two shafts - diesel, no steam plant); PC-461-class construction program context (341 steel-hulled diesel chasers built 1941-44 by ~14 yards incl. JeffBoat); GAO HRD-80-2 Navy asbestos-era documentation (see ev-06) [other_primary]

- Finding type
- asbestos_application
- Finding
- A steel-hulled PC-461-class diesel submarine chaser built February-August 1942 sits inside the Navy's documented asbestos-use era; era-standard applications aboard a diesel patrol craft of this type and period were engine and exhaust lagging, machinery-space thermal insulation, gaskets, valve packing, electrical insulation, and fireproofing/deck coverings. As a twin-screw diesel craft she carried no steam plant - the boiler/turbine lagging pathway of steam vessels does not apply.

- Finding
- GAO documented that the Navy used asbestos insulation extensively aboard ships and did not begin substituting alternative insulation materials until the early 1970s - spanning this hull's entire construction (1942), U.S. service era (1942-44), and French transfer period.

- Finding type

- Finding
- No qualifying ship-specific asbestos record located for this hull: no asbestos survey, abatement contract, hazmat disclosure, material specification, or verified litigation naming PC-562 / L'Attentif was found in the public sources searched. CAVEAT: CourtListener could not be queried this session - the fleet-wide request pacing budget was exhausted on every attempt (helper's stand-down instruction honored) - so litigation status is logged as blocked, not as a negative result. Secondary web sweeps surfaced no qualifying case; the only 'asbestos' content is law-firm marketing material (elglaw.com's occupational page lists 'Jeffboat - Jeffersonville Boat & Machine Co.' generically among shipyards; generic ship-list listicles) asserting asbestos without primary sourcing - excluded by source policy.

- 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 run). NARA RG 24 deck logs, builder work packages, and French naval records are undigitized leads. Does not establish or defeat any claim of exposure or legal eligibility.
