- Argentine acquisition and career record (histarmar, citing Armada Argentina records B.N.P./OO.GG/OO.DD/A.G.M.): acquired by decree N. 24.766 of 1947-08-20 from the firm Higgins Inc. for US$300,000 'con equipos completos de reparaciones: hornos, talleres de precision, etc.' (with complete repair equipment: furnaces, precision workshops); flag raised 1947-12-29; incorporated into the Armada 1948-03-12 by decree N. 7035; fitted out at Norfolk during the first half of 1948 and sailed in a two-ship convoy with her sister ARA Ingeniero Iribas (Q-21, ex-LST-81) from Stormy Point, Virginia 1948-05-01, arriving Buenos Aires 1948-06-20; participated in the Revista Naval at Buenos Aires 1948-07-10; assigned to Base Naval Puerto Belgrano, then (1950) to the Mar del Plata submarine base as repair ship (buque taller), with salvage and support duties incl. Ushuaia deployments (1949-1950) and the salvage of the steamer Otono (1950); during the Revolucion Libertadora (1955) she joined the rebel fleet in operations over Buenos Aires; radiated (struck) by decree N. 12306 of 1960-10-06, which also authorized sale; laid up in disarmament at Base Naval Rio Santiago 1961-68; sold at public auction in 1963 to Bottachi S.A. for m$n 22,000,000; entered national merchant registry as 'Tierra del Fuego', owner Bottachi S.A., and underwent modernization (1968) at the Mestrina S.A. yard for m$n 50,000,000.

- Limitations
- Spanish-language secondary compilation citing Argentine naval records; it documents the repair-ship outfit (furnaces, precision workshops) carried aboard this hull at sale - ship-specific equipment evidence, but it says nothing about the asbestos or insulation content of that equipment. Internal anomaly: one sentence renames the ship 'ARA Ingeniero Iribas' although the page, captions and numeral Q-22 consistently indicate Ingeniero Gadda (Iribas was Q-21, ex-LST-81) - treated as a transcription slip, noted in gaps. Not an asbestos source.

- Finding
- Era-typical asbestos-relevant product classes for this hull type and period: the LST-1-class design carried a diesel plant (2 x GM 12-567A per the BuShips Ships' Data 1945 v2 design table) with no boilers, narrowing the steam-lagging pathway; asbestos-relevant applications aboard a 1943-built amphibious auxiliary of this type were engine and diesel-exhaust lagging, machinery gaskets, valve packing, electrical insulation, deck coverings, and accommodation insulation. The Achelous-class repair-ship conversion added a workshop/furnace outfit (furnaces and precision workshops aboard this hull documented at Argentine delivery - ev-uss-lst-82-lst82-03); furnace refractory and shop insulation products of the era commonly contained asbestos.

- Limitations
- Class/era inference only - no hull-specific insulation survey, material list, or work package located for LST-82/ARL-6. Names era-standard application classes, not confirmed installed materials; no quantity, no manufacturer attribution. The diesel plant removes the boiler-lagging pathway typical of steam auxiliaries; the furnace/workshop pathway rests on ship-specific outfit documentation but its insulation content remains era inference, not a fiber-specific record.

- Finding type
- historical_record
- Finding
- Academic history of the LST-to-ARL conversion program: within one year of the first LST the Navy began converting dozens of the ships to Landing Craft Repair Ships (ARL) and other auxiliary classes for logistics-support roles; COMINCH ordered the first conversions in December 1942 and directed the LST-10 conversion (the first ARL) in February 1943; already-commissioned LSTs were decommissioned at conversion shipyards before rework. This hull was converted in the build window - redesignated ARL-6 on 1943-07-20 before its brief USN commission - consistent with the program's shift to converting new-construction hulls.

- Limitations
- Class/program-level scholarly context for the ARL conversion program generally; does not document this specific hull's conversion yard or work scope. The sequence 'decommissioned LSTs then converted' describes already-commissioned ships - this hull was redesignated before commissioning, a different branch of the program.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or verified litigation naming USS LST-82 / ARL-6 / HM LSE-2 / ARA Ingeniero Gadda / MV Tierra del Fuego was found in the public sources searched (see search_ledger). CAVEAT: CourtListener could not be queried this session - the authenticated API quota (shared fleet-wide) was exhausted with ~10 h to reset; logged as blocked in search_ledger, not as a negative result. The only 'asbestos aboard' material located is law-firm marketing content (e.g., a mesowatch.org exposure-page entry for the builder, Jeffersonville Boat & Machine) asserting era-typical asbestos without primary sourcing - excluded by source policy. Most of this hull's service life ran under foreign flags (Royal Navy 1943-46; Argentine Navy 1947/48-1960; Argentine merchant flag 1968-), placing the bulk of any exposure documentation outside U.S. repositories.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - and the litigation repository search is a genuine open gap (quota-blocked, not run). Foreign-flag service (RN, Argentine Navy, merchant) means US-centered repositories are the wrong place to look for most of this hull's life; Argentine naval archive records (the histarmar source base) were not queried for hazmat content. Deck logs (NARA RG-24 for the seven-day US commission; TNA UK for the RN period) are undigitized leads. Does not establish or defeat any claim of exposure or legal eligibility.
