   Finding

   NavSource Service Ship Photo Archive page for ARD-32 supplies the chronology: ARD-12 Class Auxiliary Repair Dock, laid down date and place unknown; commissioned USS ARD-32 date unknown; decommissioned date unknown; struck from the Naval Register 25 June 1992; transferred 9 November 1987 to Chile under the Security Assistance Program, named Mutilla; disposition 'active Chilean navy' (page last updated 29 August 2014). Specifications: displacement 5,200 t, length 492 ft, beam 81 ft, draft 6 ft; call sign NHZU; awards American Campaign Medal and World War II Victory Medal only (no Asiatic-Pacific ribbon, no battle stars). Five official Navy-yard photographs document the dock at Mare Island Naval Shipyard: Navy Yard Mare Island photo #610-45 shows USS Cod (SS-224) drydocked in ARD-32 on the quay wall, with USS Abatan (AW-4) in dry dock #3 and USS New Orleans (CA-32) in dock #2, 23 January 1945; photo #2786-46 shows ARD-32 at Mare Island 1 August 1945 with USS Blower (SS-325) in dock, USS Eldorado (AGC-11) moored alongside and yard derrick YD-33 aft; a US Navy photo (courtesy Vallejo Naval and Historical Museum) shows USS Gosselin (APD-126) docked in ARD-32 at Mare Island 12 February 1946; USS PCS-1445 and USS PCS-1446 entering ARD-32 at Mare Island 3 April 1947; and Mare Island photo #10946-11-51 shows ARD-32 with USS Charr (SS-328) docked opposite USS Juneau (CLAA-119), with USS Gurke (DD-783) and USS Rowan (DD-782) aft, 2 November 1951. A contributor photo shows Mutilla (ex-ARD-32) moored alongside sister dock Ingeniero Mery (131) (ex-ARD-25) at a Chilean naval station.

The page's lead caption contains a copy error ('USS ARD-25) was acquired by Chile and named Mutilla' - it was ARD-32 that became Mutilla; ARD-25 became Ingeniero Mery). Its 'transferred 9 November 1987' date conflicts with Chilean-documented physical arrival in 1960 - see the correction row (ev-uss-ard-32-ard32-08). Struck date and 1987 lease action rest on the compilation consistent with the Japanese-language Naval Register digest (jounin.jp), which renders 1987/11/9 as a lease to Chile.

   Finding

   Bureau of Yards and Docks official WWII history (Chapter IX, 'Floating Drydocks') documents the class to which this hull belonged: the ARD type is defined as 'Mobile, military, steel unit dock, ship-form hull, with a normal lifting capacity of 3,500 tons, for destroyers, submarines, and small auxiliaries.' The original group (ARD-2, ARD-5, and six others of the same dimensions built 1942-43) measured 485 ft 8 in long, 71 ft wide, 413 ft usable length, 49 ft 4 in clear width, 21 ft depth over blocks. Because the rapid production of landing craft in 1942 dictated mobile drydocks capable of handling LSTs of greater beam, 'all subsequent docks of this class were built to revised designs providing a clear width of 59 feet between the wing walls' - the revised group into which ARD-12-class hulls including ARD-32 fall. Class design features: integral unit steel hull stressed for ocean towing; bottom pontoon divided into ballast tanks; watertight safety deck in wing walls and bow; two pumping plants of two 15,000-gpm vertical-shaft pumps each; two machinery decks in the wing walls carrying pump and valve motors, welding equipment, main diesel generators, and crew quarters and messing; hull repair shop in the bow; four railway-type diesel engines directly connected to electric generators; provision made for low-power propulsion but no dock was ever so equipped; bottom-hinged stern gate; two 10-ton jib cranes; trans-Pacific tows averaged 6-8 knots.

   Finding

   Chilean defense-press accounts document the end of service: in early August 2025 the Chilean navy sank the former floating dock Mutilla in a weapons exercise off the Biobio region coast, using RIM-7P Sea Sparrow missiles fired by M-class multipurpose frigates FF-15 Almirante Blanco Encalada and FF-18 Almirante Riveros of the Escuadra Nacional; fleet tug ATF-65 Janequeo towed the dock to the sinking position. The same accounts record that the dock was built in 1943 at Pacific Bridge, Alameda, California; that Chile acquired it and it was towed from San Diego by the tug Yelcho (ATF-64, ex-USS Tekesta AT-93); and that it arrived at Talcahuano on 7 September 1960, then served more than six decades at ASMAR Talcahuano in maintenance of fishing vessels and Chilean navy surface and submarine units. This was not the first such exercise - the navy used Sea Sparrow missiles to sink the hull of ex-icebreaker AP-46 Almirante Viel in 2021.

   historical_record

   Finding

   Transfer-date discrepancy resolved as far as public sources allow: (a) Chilean sources document the physical transfer - towed from San Diego by Chilean tug Yelcho (ATF-64, ex-USS Tekesta AT-93), arriving Talcahuano 7 September 1960, and 'more than six decades' of ASMAR service (1960-2025); shipbuildinghistory likewise gives 'To Chile 1960 as Mutilla (132)'. (b) NavSource gives 'Transferred, 9 November 1987, to Chile under the Security Assistance Program' and 'Struck from the Naval Register, 25 June 1992'; the Japanese-language Naval Register digest (uswarships.jounin.jp) renders 1987/11/9 as a lease (貸与) to Chile and repeats the 1992/6/25 strike. (c) Pub.L. 103-54 (28 July 1993) authorized a sale of ARD-32 to Chile. The most consistent reading: a 1960 lease/loan transferred the hull to Chilean custody while the US retained title (keeping it on the Naval Register), a register-level lease action was logged 9 November 1987, the dock was struck 25 June 1992, and title passed by sale under the 1993 statute. NavSource's phrasing compresses the 1987 lease action into the original transfer event.

Asbestos presence aboard this hull is inferred from era construction practice and onboard machinery, not proven; a floating drydock has no steam propulsion plant, so its asbestos loading would be materially lower than a steam vessel's and confined to machinery/habitability materials. Establishes nothing about quantity, condition, past or present-day presence aboard the sunken hull, individual exposure, or causation.

    Limitations

    Type-level legal doctrine, not hull evidence - no party, vessel, or facts involving ARD-32. Establishes only the litigation posture historically applicable to moored floating drydocks; says nothing about asbestos aboard this or any hull and establishes or defeats no claim of exposure or eligibility.

    Finding

    No qualifying ship-specific asbestos record located: no asbestos survey, abatement record, hazmat disclosure, materials statement, or docketed case naming ARD-32 was found in the public sources searched - including the official BuDocks class-design history, the five official Navy-yard photographs of this dock at Mare Island, the official Chilean navy tsunami-refloat record, the federal sale authorization statute, and the CourtListener sweep (see search_ledger).

    Limitations

    Absence of a located public record does not prove absence of asbestos aboard - a 1943-44-built Navy service craft with diesel-electric machinery is era-consistent with incidental asbestos-containing materials, but no ship-level documentation was located. The hull is now sunk off the Biobio coast, so no present-day survey is possible. Does not establish that asbestos is or was present; does not establish or defeat any claim of exposure or legal eligibility.

    Archival leads (not retrieved - require research-room or reproduction order; no spend authorized): NARA RG 181 records of Mare Island Naval Shipyard (docking records, yard photo originals #610-45/#2786-46/#10946-11-51 and docking registers naming ARD-32); NARA RG 71 (Bureau of Yards and Docks) for the ARD construction program and Pacific Bridge contract records; NARA RG 19 (Bureau of Ships) for revised-design class characteristics; NAVSEA/SECNAV ship status-change files and DSCA FMS case records for the 1960 lease, 9 November 1987 lease action, 25 June 1992 strike, and 1993 sale; Armada de Chile historical archive and ASMAR Talcahuano yard records for Mutilla (132) service 1960-2025; Vallejo Naval and Historical Museum photograph holdings (Gosselin-docking photo source). Note: NARA Special List 44 indexes NO deck-log series for ARD-32 (ARD block runs ARD-1 through ARD-30 with no 31-33 entries) - the log index's silence is consistent with the dock never having been commissioned.

    Limitations

    Record-group and repository mapping only - no box-level retrieval performed; existence of asbestos-specific documents for this hull is unknown until surveyed in person. The SL-44 absence is a verified index fact but does not by itself prove non-commissioning (service-craft logs could be filed under yard/station records). Nothing in this row is an asbestos finding.
