- Official BuShips register entry: 'Ships' Data, U.S. Naval Vessels, 1945' (NAVSHIPS 250-012, Vol. III, auxiliaries volume) construction table lists ATR-87 built by Kruse & Banks S.B. Co., Inc., North Bend, with keel 26 Feb 44, launch 20 Sep 44, and commissioning 31 Oct 44. The machinery table hull row (no. 74) lists a Prescott Co. vertical triple-expansion engine with Foster Wheeler 'D'-type boilers. The class row for group ATR 50-89 gives: wood hull; 165'5" oa x 155'0" wl x 33'4" beam; 12.2 kt trial speed; ~1,312 t trial displacement; 1,600 shp, one screw, 2 boilers at 260 psi saturated; armament one 3"/50 cal DP plus two 20mm; accommodations 5 officers, 47 enlisted; 60 kW turbo ship's-service generators at 120 V DC; fuel capacity 1,620 bbl; largest boom 4 t; limiting draft 15'10" (average maximum load for class).

- Defense Nuclear Agency dose-reconstruction report (NTPR program) for Operation Crossroads support ships gives a ship-specific section for USS ATR-87: crew size 69; group SALVAGE; mission 'salvaging the damaged target vessels after the tests, performing emergency repairs, and fighting fires.' The reconstructed path report (built from the ship's deck log) shows ATR-87 observing Shot Able from ~24 miles east on 1 Jul 1946, entering Bikini lagoon that day, arriving at USS Pennsylvania to fight fire and at USS Cortland to fight fire, standing by Haven, mooring alongside Nevada, moored to Salt Lake City and alongside Nagato, conducting washdowns of the beached USS Hughes plus USS Dentuda and USS Pensacola after Shot Baker, and towing LCT-1114, APL-27 (departing for Kwajalein), LCT-815, and LCT-1112 movements. Total calculated dose received while at Bikini: 0.485 rem; departed Bikini 1 Sep 1946 (Baker +38); ship contamination factor at departure: 4.

- Limitations
- Official government technical report with a ship-specific section built from this hull's deck log - the strongest operational record located. Content is radiological (film-badge dose reconstruction for NTPR veteran dose assessment), NOT asbestos documentation; it establishes Crossroads presence, duties, and movements only. OCR of the scanned PDF is imperfect (e.g., 'ATR-67'/'ATR-B7' garbles in the path-report header area); figures used here come from the section's printed summary lines. A date reading '24 August 1945' in the APL-27 excerpt is an OCR/context artifact of the 1946 sequence.

Alden firm per one source) and that the 80 wooden ATRs averaged 9.4 months keel-to-launch and 13.6 months keel-to-commissioning.

- Source discrepancies documented, with resolution where the register is controlling: (a) Build dates - NavSource prints laid down 10 Jul 43, launched 4 Mar 44, commissioned 8 Aug 44 for ATR-87; NAVSHIPS 250-012 and shipscribe both print keel 26 Feb 44, launch 20 Sep 44, commissioned 31 Oct 44. NavSource's dates are identical to ATR-88's official dates (Burger Boat: keel 10 Jul 43, launch 4 Mar 44, commissioned 8 Aug 44) - a copy-over error between sister pages; NARA SL-44's deck-log index corroborates the official version (ATR-87 log run opens 10/31/1944; ATR-88's opens 8/8/1944). (b) Engine builder - official machinery table prints 'Prescott Co., vert., 3-exp.'; NavSource prints 'Preston Co.' - likely transcription error; Prescott Co. carried as controlling. (c) Boiler pressure - official 260 psi sat vs NavSource 200 psi. (d) Strike date and fate - NavSource 'struck date unknown / fate unknown' vs shipscribe's documented struck 7 Feb 47, MC custody 2 Jul 48, MA sale 18 May 48, delivery to Robert O. Fleming & Co. 5 Jul 48; the documented chain is adopted. (e) Ordered date 27 Feb 43 rests on shipscribe's compilation of the contract award (consistent with the NAVSHIPS build contract listing) - carried, flagged as compilation data.

- Finding
- Era-level inference only: peer-reviewed 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 rescue tug was built. Unlike diesel sisters of other auxiliary types, this hull carried a full steam plant (two Foster Wheeler 'D'-type boilers at 260 psi, Prescott Co. triple-expansion engine, steam auxiliaries): period steam systems commonly used asbestos-containing boiler insulation, steam-line lagging, valve and flange gaskets, packing, and insulation felts, and towing/winching brake linings of the era commonly contained asbestos. The wooden hull bounds the plausible scope to machinery-space and piping applications rather than structural fireproofing.

- Program/era-level scholarship only - does not name this vessel or the ATR-1 class and does not establish that asbestos was aboard this hull, nor quantity, location, condition, individual exposure, or causation. No class- or design-specific material documentation for ATR tugs was located. The applications named are general era practice for steam vessels, not documented aboard this hull. The wooden hull reduces but does not eliminate plausible scope.

- Finding
- NARA Special List #44 (List of Logbooks of U.S. Navy Ships, Stations, and Miscellaneous Units, 1801-1947, by ship number) indexes one deck-log run for this hull: 'ATR-87 10/31/1944 - 6/30/1945' - held in Record Group 24 (Bureau of Naval Personnel), Entry 118, at the National Archives at College Park. The run's opening date matches the official commissioning date (31 Oct 1944), independently corroborating it against NavSource's conflicting print. This hull does not appear on NARA's published list of digitized deck logs in the National Archives Catalog (no ATR-series hull is on that list), so the run is retrievable only via Archives II textual reference. Coverage limitation: nothing is indexed for July 1945 onward - yet the DNA-TR-82-05-V3 path report demonstrates the July-September 1946 deck log (Okinawa aftermath through Operation Crossroads) exists and was used for dose reconstruction; post-June-1945 runs are simply not in the SL-44 index for this hull.

Litigation search, authenticated CourtListener API v4 (2026-09-26): opinion search '"ATR-87"' returned zero hits; docket/RECAP search '"ATR-87"' returned two hits, both classified as name collisions - LaSalle Business Credit LLC v. Gitto (D. Mass. 04-cv-12227, a RICO docket where the token appears inside a filing) and Muir v. DHS (D.C. Cir. 22-1318) - neither names the vessel nor involves asbestos. A fallback general web litigation search surfaced only unrelated 'ATR' collisions (Australian Tax Reports citations) and ship-history pages. Additional negatives: no DANFS entry exists for this unnamed hull (NavSource confirms none; DANFS covers named vessels); no NVR ship-detail record (hull stricken 1947, predating the register's online coverage); MARAD ShipHistory search returned only an application error to automated queries this session.
