- asbestos_application
- 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 1943-44 auxiliary repair dock was built, and that wartime demand drove unprecedented asbestos utilization aboard U.S. naval vessels.

- Chapter IX, 'Auxiliary Repair Dock' section, pp. 215-216 (wing-wall machinery decks, diesel generators, welding equipment, crew quarters/messing, no propulsion fitted)
- Finding type
- asbestos_application
- Finding
- No ship-specific asbestos record located. Class/era inference only: the official Bureau of Yards and Docks history of WWII floating drydocks documents that ARD-type docks carried their own diesel-electric power plant (four railway-type diesel engines directly connected to electric generators), two pumping plants, welding equipment and repair shops, and crew quarters and messing in the wing-wall machinery decks - a self-sustaining industrial facility built in the 1943-44 period when asbestos insulation products were standard in U.S. naval construction. Era-typical asbestos applications for such a facility include insulation and gaskets on diesel-generator exhaust and piping, gaskets and packing in pump/valve machinery, electrical insulation, fire-resistant bulkhead and deck panels, welding-area heat shielding, and brake linings on winches and cranes. A second exposure-relevant era is documented for this hull: the 1967-68 rebuild at Norfolk Shipbuilding and Drydock Corp., a private repair yard working in the period when asbestos products were still standard marine materials.

- Limitations
- Class/design documentation, not a hull record - the official history describes the ARD type generally, never names ARD-18/ARDM-3, and contains no 'asbestos' statement; the conversion event is documented but its materials scope is not. Asbestos presence aboard this hull is era inference, not ship-proven. Does not establish quantity, location, present-day presence, individual exposure, or causation.

- Chapter IX, 'Auxiliary Repair Dock' section, pp. 215-217
- Finding type
- vessel_history
- Finding
- The Bureau of Yards and Docks' official history defines the ARD type as 'Mobile, military, steel unit dock, ship-form hull, with a normal lifting capacity of 3,500 tons, for destroyers, submarines, and small auxiliaries,' and documents the design: a bottom pontoon subdivided into ballast tanks; wing-wall machinery decks housing two pumping plants (each with two vertical-shaft 15,000-gpm pumps), pump and valve motors, welding equipment and storage (C deck), and main diesel generators, heavy equipment, and crew quarters and messing (B deck); power from 'four railway-type diesel engines directly connected to electric generators'; a bottom-hinged stern gate; and a carpenter-shop barge moored alongside, powered by the dock. Provision was made for low-power electric-drive propulsion machinery, but 'none of the docks was actually equipped with propulsion.' Later docks of the type were widened to a 59-foot clear width between wing walls to accommodate LSTs - the enlarged ARD-12 design, consistent with this hull's documented 81-ft beam.

Jacobsen in command; assigned to the Asiatic-Pacific Theater in WWII, servicing ships at Guadalcanal and Ulithi; decommissioned 1 July 1946; in Norfolk Shipbuilding and Drydock Corp.'s yard circa 1967-68 where she was lengthened by adding a 100-ft midsection and an additional deck above the uppermost crane deck; named and redesignated Medium Auxiliary Repair Dry Dock Endurance (ARDM-3); laid up at Charleston Naval Shipyard, date unknown; struck from the Naval Register 31 July 1995; disposed of by transfer to the Local Redevelopment Authority 1 April 1996.

This is the documented mechanism behind the NVR milestone showing ARDM-3 'disposed of by transferring to the Local Redevelopment Authority (LRA)' on 04/01/1996 - the same date the base closed.

Classification of that hit: UNRESOLVABLE name mention at a pretrial stage - which 'Endurance' hull the document names (this drydock ARDM-3, the Agile-class minesweeper USS Endurance AM-435/MSO-435 - a crewed ship and the more likely reference in a sailor's service history - USCGC Endurance, or another) cannot be determined from the docket metadata captured, and the phrase occurs inside a magistrate's pretrial recommendation document, not a vessel-specific adjudicated finding.

- CourtListener coverage is not exhaustive - state-court filings, MDL-875 claimant exhibits, and PACER-only dockets may not be indexed; a negative or collision-only result does not prove no claim ever named the dock. The lone 'USS Endurance' docket hit is genuinely ambiguous: the matched text sits inside OCR'd PDF documents whose snippet context was not returned, and 'Endurance' is a reused Navy name; a sailor's 'USS Endurance' service entry in an asbestos case most plausibly refers to the AM-435 minesweeper, not this floating drydock. Classified down per the least-final-stage rule: unresolvable pretrial mention, not qualifying litigation for this hull - flagged for the AM-435 record owner.
