- Official wartime BuShips publication, scanned from a declassified copy - the strongest official source located for this hull. 'Date of first commission' is the BuShips administrative column; NavSource records the same 13 Dec 1944 commissioning date with commanding officer detail. Boiler pressure differs from NavSource's 200 psi figure (see gaps). Contains no asbestos, insulation-material, or crew-health information; establishes identity, construction, and plant characteristics only. Does not establish exposure, causation, or legal eligibility.

- NavSource Service Ship Photo Archive page for USS ATR-11: ATR-1 class rescue tug laid down 18 February 1944 at Frank L. Sample Shipyard, Boothbay, ME; launched 3 October 1944; commissioned 13 December 1944 with LT Schuyler M. Meyer Jr., USNR, in command; assigned during World War II to the Asiatic-Pacific Theater, Service Squadron Two; decommissioned 27 March 1946; struck from the Naval Register 17 April 1946; 'Final Disposition, fate unknown.' Awards listed: American Campaign Medal, Asiatic-Pacific Campaign Medal, World War II Victory Medal; call sign NGRA. Commanding officers listed: LT Schuyler M. Meyer Jr. USNR (13 Dec 1944 - 9 Jul 1945); LT R. H. Matheson (no dates); LT Robert W. Schmidt USNR (? - 27 Mar 1946). Page carries three photographs: USS ATR-11 alongside the Japanese battleship IJNS Nagato off Yokosuka Navy Base 'just after the surrender of Japan ending World War II' (credited U.S. Navy and Marine Corps Museum/Naval Aviation Museum Photo No. 1996.438.046), and two views of ATR-11 moored pierside at Hunters Point Naval Shipyard, San Francisco, circa March 1946 (contributed by LT Robert W. Schmidt, USNR, her final commanding officer). 'There is no DANFS history available for USS ATR-11.'

Service-squadron assignment (Service Squadron Two, Asiatic-Pacific) is stated only here - consistent with, and corroborated in part by, the credited NNAM photograph showing her alongside IJNS Nagato at Yokosuka after the surrender. Hunters Point presence circa March 1946 coincides with her 27 March 1946 decommissioning; the caption does not itself state decommissioning occurred there. Contains no asbestos information.

- NARA Special List No. 44, 'List of Logbooks of U.S. Navy Ships, Stations, and Miscellaneous Units' (by ship number), lists logbook holdings for ATR-11 covering 12/13/1944 through 6/30/1945 - the commissioning date through mid-1945. The list confirms both the hull's existence in Navy records and that original deck logs for most of her commissioned period are held at the National Archives.

The 6/30/1945 end date is the coverage cutoff of the accessioned block indexed in this list - not the end of the ship's service; deck logs for July 1945 through the March 1946 decommissioning would be in the main 'Logbooks of U.S. Navy Ships and Stations' series (1941-1992) at NARA, not located in digitized public sources. Contains no asbestos, materials, or condition information.

- Shipscribe ATR-1 class compilation (transcribed from U.S. National Archives / Bureau of Ships records): ATR-11 ordered under a contract dated 12 Jun 1942 to Frank L. Sample (Boothbay Harbor, ME) covering ATR 7-12; keel 18 Feb 44, launched 3 Oct 44, commissioned 13 Dec 44. Disposition table row for ATR-11: decommissioned 27 Mar 46; struck 17 Apr 46; disposal method MC/D (Maritime Commission disposal), disposal recorded 5 Oct 46, transferred/delivered to Maritime Commission custody 2 Oct 46. Class notes record that CNO directed construction of ATR 1-40 on 19 Jan 1942 under the Maximum War Effort (1,799-vessel) Program, that the type was built of wood with relatively simple triple-expansion steam machinery so that small shipbuilders outside the main Navy shipbuilding effort could construct them, and that one source attributes the design to the firm of John G. Alden.

- Secondary compilation of NARA/BuShips primary records, not itself an official publication - build and strike dates corroborated by the official Ships' Data 1945 and by NARA Special List 44; disposal dates consistent with NavSource's strike date. The MC/D chain records the handover to Maritime Commission disposal in October 1946; the ultimate disposition (sale, scrap, or further service) is not stated - 'fate unknown' per NavSource.

- Finding
- Peer-reviewed historical study 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 rescue tug was built at Frank L. Sample, Jr., Boothbay Harbor, ME (1944), and fitted with a fired steam plant (two Foster Wheeler 'D'-type boilers, 260 psi saturated; vertical triple-expansion engine).

- Program/era-level scholarly documentation (article itself verified) of asbestos use in WWII shipbuilding generally; does not name this vessel, this class, or this yard, and does not establish that asbestos was or remains aboard this hull, nor quantity, location, condition, exposure, or causation. The hull is wooden - era-typical asbestos applications would concentrate in the machinery spaces (boilers, steam lines, gaskets, packing) and winch/windlass brake linings rather than hull structure.

- CourtListener sweep (authenticated API v4, 2026-09-26): exact-phrase opinion searches for 'ATR-11' and space variant 'ATR 11' returned 0 results. RECAP docket searches for 'ATR-11' and 'ATR 11' each returned 25 dockets (overlapping set), all name collisions in which the string appears as a document-text substring (exhibit labels, part/model numbers) in unrelated matters (ERISA, antitrust, patent, bankruptcy, criminal dockets) - none naming the vessel, none asbestos-related; no result's text contains any tug/naval/vessel context. No qualifying asbestos litigation or other litigation naming the hull located.

- Limitations
- Absence of a docketed case is not evidence about shipboard conditions; a litigation sweep cannot find or exclude hull-specific asbestos exposure. A short-service wartime auxiliary would in any event be an unlikely named defendant - WWII Navy personnel asbestos claims typically proceeded against product manufacturers or the United States.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or docketed case naming USS ATR-11 was found in the public sources searched (see search_ledger). No DANFS/NHHC vessel page exists for this unnamed hull (NavSource and NHHC site search concur); the official Ships' Data 1945 machinery entries describe plant equipment without materials content. The asbestos-relevant populations are the construction trades at the Frank L. Sample, Jr. yard (Boothbay Harbor, ME, 1944), the wartime crew (design complement 5 officers + 47 enlisted, Service Squadron Two, Asiatic-Pacific), shipyard personnel at Hunters Point Naval Shipyard around the March 1946 decommissioning, and whoever received or scrapped the hull after Maritime Commission disposal in October 1946 - none documented for asbestos for this hull.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a 1944 wartime steam tug is era-consistent with asbestos-containing machinery insulation, gaskets, and packing having been installed, and nothing located documents removal. Does not establish that asbestos is or was present; does not establish or defeat any claim of exposure or legal eligibility.
