- NavSource 'Specifications' block; Shipscribe class machinery ('1 screw, vertical triple expansion', 1,600 HP) and class notes on the wooden-hull/simple-machinery design decision
- Finding type
- asbestos_application
- Finding
- ATR-52's documented propulsion plant - one Fulton Iron Works vertical triple-expansion reciprocating steam engine of 1,600 hp fed by two Foster Wheeler 'D'-type boilers at 200 psi saturated, single propeller - is a steam installation of standard WWII construction vintage. Insulation, gaskets, and packing on such plants were era-typical asbestos applications (boiler casings, steam-line lagging, flange and valve gaskets, machinery packing). The ATR-1 class was deliberately built of wood with 'relatively simple triple expansion steam machinery' so that small yards and machine shops could produce them outside the main naval shipbuilding effort.

- Finding
- Peer-reviewed historical scholarship documents that asbestos was used extensively as a fireproofing and insulating material in U.S. shipbuilding during World War II - the era and program under which this 1943-44 steam-powered auxiliary was built - and that wartime demand drove unprecedented asbestos utilization aboard ship hulls of the period.

- Absence of a located public record does not prove absence of asbestos aboard - a 1943-44 steam plant is era-consistent with asbestos-containing insulation, gaskets, and packing. The hull passed into private ownership in 1946, so any later-condition records are in private hands if they exist. Does not establish presence or absence; does not establish or defeat any claim of exposure or legal eligibility.

Docket search for '"ATR-52"' returned 2 hits - Stolt-Nielsen Transportation Group Ltd. v. United States (D.D.C. 1:05-cv-02217, filed 2005) and Stolt-Nielsen Transportation Group Ltd. v. U.S. Department of Justice (D.D.C. 1:06-cv-00474, filed 2006) - both FOIA cases in which the string appears in document/exhibit metadata; classified as name collisions, non-qualifying. A builder-yard check on '"Colberg Boat Works"' returned 2 hits, both the same case - Colberg, Inc. v. State of California ex rel. Dept. Pub. Wks., 67 Cal. 2d 408 (1967) - an eminent-domain action over impaired shipyard access to the Stockton Deep Water Ship Channel; yard-level other litigation, non-qualifying for asbestos. No qualifying asbestos litigation naming USS ATR-52 or its builder was located.

- CourtListener coverage is opinion- and RECAP-docket-based; state-court filings, unreported matters, and claims resolved without docketed opinions are outside the corpus. A negative sweep does not prove no claim was ever filed. The builder-yard hits are eminent-domain litigation over channel access - they corroborate the yard's identity at the Stockton site in 1967 but carry no asbestos content.
