- Finding
- Official Navy logistics history documents ARD-23 in the wartime Pacific: 'the floating dock ARD-23 had arrived at Eniwetok 7 August' 1944 under Service Squadron Ten; in October 1944 Lt. Comdr. N.H. Geisenhoff, 'commanding the drydock ARD-23,' was left in charge of service matters at Eniwetok (equipment including three floating drydocks) when the squadron flagship moved to Ulithi; the appendix lists 'ARD-23 - LtComdr N.H. Geisenhoff' among commanding officers of Service Force Pacific floating drydocks.

- Finding
- At Ulithi in March 1945, 'docking facilities for destroyers were furnished by ARD-13, ARD-15, and ARD-23.' After the Ringgold/Yarnall collision, 'on the 14th, she [Yarnall, DD-541] entered ARD-23 for the construction of a false bow, which was built to about 3 feet above water' - a documented battle-damage docking event aboard this hull.

[4]'Building the Navy's Bases in World War II: History of the Bureau of Yards and Docks and the Civil Engineer Corps, 1940-1946' (U.S. Government Printing Office, 1947), Vol. I, ch. IX 'Floating Drydocks'; verbatim transcription via HyperWar [other_primary]

- Ch. IX, 'Floating Drydocks' - ARD type description (485 ft 8 in docks; C/B deck machinery; repair shops; carpenter barge)
- Finding type
- asbestos_application
- Finding
- The BuDocks official history documents the ARD type as self-contained steel repair docks: wing-wall 'C deck accommodated the pump and valve motors, small machines, welding equipment, and storage spaces' and 'B deck accommodated the main diesel generators and other heavy equipment, as well as quarters and messing facilities for the crew'; a hull repair shop in the bow; four railway-type diesel engines driving electric generators; and a covered wooden carpenter-shop barge moored alongside each dock. ARD-23 is a wartime dock of this type (delivered 1943-44 series). Era-typical asbestos applications aboard such a platform - machinery gaskets and packing, service-pipe and flange insulation, electrical insulation, quarters bulkhead/deck materials, and welding/fireproofing consumables - are inferred, not documented.

- Limitations
- Type-level facilities description, not a material specification - the chapter names no insulation products and never says 'asbestos'; no class material list located. ARD-23 was non-self-propelled (no boilers or steam plant). Asbestos presence aboard this hull is era inference only, not ship-proven; does not establish quantity, presence today, or any individual exposure.

- Finding
- The Naval War College Archives holds primary ARD-23 records not digitized online: an 8.5x11 photograph of the dock's 1944-1945 dockings list 'by ship class and number, then by date docked-undocked,' and crew photographs, one with an attached crew name list. The dockings list is the strongest known lead for the hull's complete repair workload.

- Finding type

- Finding
- Public Law 103-54 section 1(a) authorized the Secretary of the Navy to transfer 'the auxiliary repair dry dock (ARD 23)' to Argentina 'on a grant basis under section 519 of the Foreign Assistance Act of 1961 (22 U.S.C. 2321m; relating to transfers of excess defense articles).' The statute confirms the hull remained a U.S. naval vessel on the register through its 1992 striking, pending the grant transfer.

- The statute authorizes the transfer but does not itself record the execution date, delivery condition, or the craft's material state. The 1961 lease start and the 1992-06-25 strike date rest on secondary compilations (histarmar, NavSource); USNI Proceedings ship-status entries (Sept 1993 'currently on lease to Argentina'; May 1994 'Argentina ARD-23 Di Que Flottante (Y-1) Sale') corroborate but were accessible only at search-snippet level (page returns HTTP 403 to automated fetch).

Secondary Argentine sources describe the 1961 lease transfer (U.S. service ending 17 July 1961; Argentine flag 4 August 1961; towed from San Diego to Darsena Norte 18 October - 7 November 1961) and stations at Arsenal Naval Buenos Aires, TANDANOR, AFNE, and Mar del Plata (1990).

- Finding
- An official Argentine government article on the Arsenal Naval Mar del Plata lists among the arsenal's work 'Tareas en el ex-dique Y-1' - tasks on the ex-dock Y-1 - confirming the former ARD-23's post-2007 status as a withdrawn floating dock physically located at the Mar del Plata naval arsenal.

- Finding type

- Finding
- No qualifying asbestos litigation naming ARD-23. Opinion search returned 2 results, both name collisions: In re Marriage of Ard/Ard-Phillips (Tex. App.-Houston [14th Dist.] 2015, opinion 4292807) and Siddiqi v. Lane (N.D. Ill. 1990, 748 F. Supp. 637, a section 1983 prison case). Docket search returned 45 RECAP results on the literal token; page-1 review of all 19 unique case names shows no maritime, asbestos, or vessel-related matter - matches are BM25 token hits inside scanned filings (e.g., document/line references), not the hull.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - the craft was a manned, powered industrial repair platform built in 1944, a platform type for which era materials are plausibly relevant. Does not establish that asbestos is or was not present; does not establish or defeat any claim of exposure or legal eligibility.
