- Volunteer-compiled archive (secondary). Dates corroborate the register compilation independently; the merchant-owner chain beyond the names Storebror/Lenaship II and the 1961 disposition is single-source (NavSource) - MC-level records confirm only the 16 Dec 46 delivery to United Boat Service Corp., the two merchant names, and the Nov 1961 Port Etienne fire. 'Struck in 1946' is vaguer than the register's 3 Jul 46 - adopted the register date. No asbestos content; supports no asbestos claim.

The catalog title's date span exactly matches the commission-to-decommission dates in the register compilation (commissioned 31 May 1944; decommissioned 10 May 1946), independently corroborating Navy custody dates.

The pattern is consistent with assignment to the Caribbean Sea Frontier / Trinidad Sector during most of her commissioned life, bracketed by East Coast commissioning and inactivation activity.

- Wheeler Shipbuilding (Whitestone) yard delivery table lists ATR 60 for the US Navy: type Tug, 850 LDT, 165 ft, delivery 31-May-44, disposition 'Disposed of 1946 as Storebror, later Lenaship II, deleted 1962'. Yard history: the Whitestone yard was a second wartime facility of the Wheeler Yacht Company of Brooklyn (the Brooklyn yard built minesweepers and 230 Coast Guard patrol craft; Whitestone built tugs and coastal freighters); returned to pleasure craft after the war and closed 1948.

- asbestos_application
- Finding
- Class/era inference: ATR-60 carried a conventional WWII steam plant - one Fulton Iron Works vertical triple-expansion reciprocating engine on two Babcock & Wilcox 'D'-type boilers (200 psi, saturated), 1,600 shp, single screw (NavSource class spec block; register class line '1 screw, vertical triple expansion'). Peer-reviewed historical scholarship documents that asbestos was used extensively as a fireproofing and insulating material in U.S. shipbuilding during WWII - the era and program under which this wooden-hulled steam tug was built (1943-44) - and that wartime demand drove unprecedented asbestos utilization aboard U.S. hulls and in shipyards. Boiler insulation, steam-line lagging, gaskets, and packing were era-typical asbestos applications for such a plant.

- Limitations
- Program/era-level scholarly documentation of asbestos use in WWII shipbuilding generally; does not name this vessel and does not establish that asbestos was aboard this hull, nor quantity, location, condition, exposure, or causation. Wooden hull construction does not eliminate steam-plant insulation inference, but no materials list for the ATR-1 class was located.

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, occupational-medicine record, materials list, or docketed case naming ATR-60 (or merchant names Storebror / Lenaship II) was found in the public sources searched (see search_ledger). CourtListener API v4 (authenticated, via helper, 2026-09-26): opinion search '"ATR-60"' returned 0 results; opinion search '"USS ATR-60"' returned 0 results; docket search '"ATR-60" tug' returned 0 results - no qualifying asbestos litigation, no other litigation naming the vessel, and no name collisions in opinions or RECAP dockets; the unhyphenated variant query was blocked by fleet pacing budget contention at research time (see ledger). Structurally, essentially no ship-specific record can be generated by the usual post-service routes: the hull left Navy custody in December 1946, spent her merchant career under foreign flags (Norwegian, British, French/Mauritanian), and was destroyed by fire at Port Etienne in November 1961 - no surviving hull, no museum stewardship, no MARAD custody record, and no U.S. refit or breaking file. No DANFS entry exists for this hull (NavSource statement; canonical NHHC URL 404s).

- 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. Does not establish presence or absence; does not establish or defeat any exposure claim or legal eligibility. CourtListener sweep: exact-name opinion and qualified docket queries complete (all 0); the unhyphenated 'ATR 60' variant was blocked - residual surface negligible for a hyphenated hull number.

- Cross-source discrepancy resolution: (a) Struck date - register compilation gives 3 Jul 1946; NavSource gives only 'in 1946'. The register date is adopted; NavSource is vaguer, not contradictory. (b) Buyer chain - register ship note documents Maritime Commission delivery 16 Dec 1946 to United Boat Service Corp., New York; NavSource compresses the chain to 'sold in 1946 to A/S Hektor, Bugge & Krogh-Hansen, Oslo.' Both are consistent as a two-step: MC's documented sale was to the New York broker, and the Norwegian owner is where the mercantile name Storebror (1947) appears. (c) Final disposition - 'burned at Port Etienne 15 Nov 61' (register ship note), 'disposed of in 1961' (NavSource), 'deleted 1962' (yard table) are consistent: fire loss November 1961, register deletion lagging into 1962. (d) Complement - 5+47 (NavSource), 51 (register class line, 1944), 5+55 (HyperWar spec block): unresolved, carried in gaps.
