Alden firm.

- 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 auxiliary steam tug was mass-produced. Marine steam plants of the period (boilers, steam piping, engine cylinders) were normally insulated, and boiler lagging, pipe insulation, gaskets, and packing of the era commonly contained asbestos fiber.

- Finding
- Era/design inference: this hull is a 1943-44 wooden-hulled Navy rescue tug built to the BuShips ATR-1 design with a genuine steam plant - two oil-fired Babcock & Wilcox 'D'-type boilers at 260 psi saturated feeding a Fulton Iron Works vertical triple-expansion engine, documented per-hull in Ships' Data (ev-01). Steam naval vessels of 1943-44 were lagged, gasketed, and packed with era-standard materials, which were commonly asbestos-containing: boiler and steam-drum insulation, steam-line lagging, valve and flange gaskets, machinery packing, accommodation joiner insulation, towing-engine/winch and windlass brake linings, and deck composition. Wooden hull construction does not reduce the machinery-space insulation load. Exposure-relevant populations if any material was present: Dachel-Carter construction trades (Aug 1943 - Jun 1944); the wartime crew (design complement 52) across the Miami tow and Balikpapan service (Jun 1944 - May 1946); the 1948 Maritime Commission disposal workforce; and any Gardiner Mfg. conversion or later scrapping crews.

- Finding
- Expert declaration documents that during WWII the U.S. Navy and U.S. Maritime Commission required fireproof insulation on military and civilian vessels, and that asbestos-containing thermal insulation products (e.g., Owens-Illinois Kaylo block and pipe insulation) appeared on Navy Qualified Products Lists under military specifications Mil-I-2819 and Mil-I-2781; the declarant states that all Navy-approved products for the same temperature ranges as Kaylo in the 1940s-50s contained asbestos. ATR-56 was ordered 27 Nov 1942 and laid down 27 Aug 1943 inside this procurement regime.

- Plaintiff-side expert declaration in asbestos litigation, not a court finding - pleading-stage material classed below discovery and trial findings per litigation-stage discipline. Describes Navy-wide procurement requirements and never names this hull or the ATR class. Kaylo itself entered commercial production in 1948 - after this hull's construction - so the declaration's probative value here is the documented Navy requirement/QPL regime and the era standard of asbestos-containing thermal insulation, not any specific product aboard this hull. Does not establish asbestos aboard ATR-56, nor quantity, condition, exposure, or causation.

- Coverage is complete at the exact hull string for opinions and dockets and at the 'USS ATR-56' variant for dockets. The '"USS ATR-56"' opinion query is necessarily empty (a stricter phrase of the zero-returning '"ATR-56"' opinion query on the same index); the spaced '"ATR 56"' variant queries were repeatedly paced out by the shared fleet budget - a pending gap on a collision-prone variant, logged in gaps rather than retried into a ban. Absence of litigation does not prove absence of exposure; sailors' asbestos claims typically named product manufacturers rather than hulls, and WWII-era exposure claims against the government faced immunity barriers. Nothing in this row is an exposure finding.
