- Finding
- USS ATR-35 was an ATR-1-class wooden-hulled rescue ocean tug: ordered 1942-07-06; laid down 1942-09-16 at Lynch Ship Building, San Diego, CA; launched 1943-07-21; commissioned 1944-05-05 (LTjg. L. C. Gunn). Specifications: 852 t light / 1,315 t full load; 165'6" x 33'4" x 15'6"; 12.2 kts; one 3"/50 dual-purpose mount and two 20mm AA mounts; complement 5 officers + 47 enlisted; propulsion one Prescott Co. vertical triple-expansion reciprocating steam engine, two Foster Wheeler 'D'-type boilers 200 psi saturated steam, two turbo-drive 60 kW 120V DC ship's-service generators, single screw 1,600 shp. The ATR-1 class was deliberately built of wood with simple triple-expansion steam machinery so small yards and machine shops outside the main naval program could build them.

- Finding
- WWII service: ATR-35 served in the Asiatic-Pacific Theater and earned one battle star - assault and occupation of Iwo Jima, 1945-02-23 to 1945-02-28 (engagement P33-1). She performed Navy occupation service in the Far East 1945-09-22 to 1945-12-12; U.S. National Archives photographs SC 216511 and SC 216513 show her at Yokosuka, Japan on 1945-10-12 moored alongside the captured battleship IJNS Nagato (with USS Waupaca AOG-46). Awards listed: American Campaign Medal; Asiatic-Pacific Campaign Medal (1 star); WWII Victory Medal; Navy Occupation Service Medal (Asia clasp).

- Crew of ~52 (5 officers, 47 enlisted per listed complement)
- Limitations
- Campaign participation and occupation-service dates are documented; deck-log-level operational detail is not. The NavSource table also carries a second date line 'Iwo Jima operation, 6 to 25 June 1944' inconsistent with the official Iwo Jima period (Feb-Mar 1945) and the ship's May 1944 commissioning - treated as a transcription anomaly and logged in gaps, not asserted as a second campaign. NARA photo numbers establish the ship at Yokosuka 1945-10-12; photo content itself not independently re-verified at NARA. No asbestos content.

- Finding
- Disposition discrepancy resolved: NavSource records ATR-35 'disposed of in 1946, fate unknown' and NavalCoverMuseum records 'Transferred to War Shipping Administration August 4 1948,' while the ShipScribe register (compiled from NVR and Maritime Commission disposal records) shows decommissioned 1946-04-30, stricken 1946-10-08, delivered to Maritime Commission disposal 1948-08-04, sold (delivered) by MC to Gardiner Mfg. Co., Oakland, Cal. The WSA framing is anachronistic - the War Shipping Administration was abolished in 1946 and disposal functions passed to the Maritime Commission; the 1948 MC sale is adopted as controlling.

[4]Corn, Jacqueline Karnell, and Jennifer Starr, 'Historical perspective on asbestos: Policies and protective measures in World War II shipbuilding,' American Journal of Industrial Medicine 11(3):359-373 (1987); NavSource machinery specifications for this hull [other_primary]

- Finding type
- asbestos_application
- Finding
- Class/era inference: ATR-35 carried a 1940s naval steam plant (two Foster Wheeler 'D'-type boilers feeding a Prescott vertical triple-expansion engine). Peer-reviewed scholarship documents that asbestos was used extensively as insulating and fireproofing material in U.S. WWII shipbuilding, and insulation, gaskets, packing, and lagging in steam machinery of this era were commonly manufactured with asbestos fiber. Typical applications for a steam tug of the period: boiler and steam-drum insulation; steam-line lagging; valve and flange gaskets; machinery packing; accommodation and galley-area insulation; brake linings on towing machinery.

- Construction trades (Lynch Ship Building, San Diego, 1942-1944); engine-room crew (stokers/watertenders/machinist's mates)
- Limitations
- Era/design inference, not a hull record - no construction specification, survey, or crew account naming asbestos aboard ATR-35 was located. The ATR-1 class's wooden hull reduces the fireproofing footprint relative to steel combatants but the steam plant remains era-typical. Does not establish presence, quantity, location, condition, individual exposure, or causation.

- No qualifying ship-specific asbestos record located: no DANFS entry exists for this hull, and no asbestos survey, abatement contract, hazmat disclosure, or adjudicated case naming ATR-35 was found in the public sources searched (see search_ledger). The hull was sold out of government service in 1948 and no preservation-entity or regulatory record for it exists.

- Archival lead (partially confirmed, unretrieved): NARA Special List #44 (logbooks of U.S. Navy ships, by ship number) indexes deck logs for ATR-35 covering 1944-05-06 through 1945-06-30 - the WWII logbook accession in RG 24. Deck logs cover the ship's entire commissioned wartime career including the Iwo Jima operation. Post-June-1945 logbooks (through decommissioning 1946-04-30) are held in later accessions; BuShips contract plans/specifications for the Lynch-built tugs and any Maritime Commission sale file for the 1948 Gardiner Mfg. transaction are additional unretrieved leads.

SL-44 coverage ends 1945-06-30 (accession scope), not the ship's 1946 decommissioning. Nothing in this row is an asbestos finding.

Supp. 2d 229 (S.D.N.Y. 2013), a patent/licensing dispute where 'ATR-35' is a part-number-style token, a name collision; opinion search 'USS ATR-35' returned 0; docket search 'ATR-35' returned 2 hits (Exclusive Real Estate Investments LLC v. McLarens Inc., W.D. La. 2:21-cv-00443; High Yield REO LLC v. Certain Underwriters at Lloyd's, D. Mass. 1:19-cv-12102) - both insurance-contract cases where 'ATR-35' appears in document text as a non-vessel reference, name collisions. No qualifying asbestos litigation names the hull.

- CourtListener indexes published opinions and RECAP dockets - absence of hits does not cover unindexed filings, state-court dockets without RECAP coverage, or settled/undocketed claims. A hull-number token colliding with part numbers and policy references is expected for unnamed auxiliaries; the sweep is a negative finding for qualifying asbestos litigation, not proof no claim was ever asserted.
