[2]Consolidated era inference - BuShips Ships' Data U.S. Naval Vessels Vol. 2 (Jan 1945) LST machinery data (per lst-1-class class profile, session 2026-09-16; the shipscribe.com scan URL cited there now returns 404) + NavSource hull spec block confirming two GM 12-567A diesels on this hull + era amphibious-ship construction practice [other_primary]

- Finding type
- asbestos_application
- Finding
- Era/design inference for this diesel-powered LST: no boilers or steam plant, so no boiler/steam-line lagging pathway; asbestos-relevant applications aboard the type were GM diesel engine and exhaust lagging, valve/flange gaskets, machinery packing, thermal and acoustic insulation in accommodation and machinery spaces, deck coverings, and winch brake linings. Period insulation products were commonly manufactured with asbestos fiber.

- Limitations
- Class/era inference only - no ship-level asbestos record exists for this hull. The underlying BuShips SDB-1945 v2 scan URL (shipscribe.com/styles/usnaux/sdb/SDB1945v2.pdf) cited by the class profile returned 404 on 2026-10-02 and has no Wayback capture; the NavSource spec block itself is live and confirms the diesel plant. Establishes no quantities, no exposure, no causation for any individual.

- Finding
- Laid down 13 November 1944 by American Bridge Co., Ambridge, PA, as LST-1081; launched 5 January 1945; commissioned 30 January 1945. After shakedown and transit via the Panama Canal, arrived Pearl Harbor 4 April 1945, then ran WWII Pacific logistics shuttles: Kwajalein (8 May), Roi-Namur (20 May), Guam (27 May-10 June), Ulithi (12-28 June), Okinawa (4-15 July), Tinian/Saipan (29 July-12 August); postwar calls at Saipan, Manila, Guadalcanal; preinactivation overhaul San Francisco from 16 January 1946; decommissioned 30 July 1946, Columbia River Group, Pacific Reserve Fleet. Ordered reactivated 7 August 1950; recommissioned 2 February 1951; transferred to Norfolk via Panama Canal (arrived 12 July 1951); Atlantic Fleet amphibious training out of Little Creek; first Mediterranean deployment 13 April-4 October 1955; named Pima County effective 1 July 1955; in reserve in commission 7 August 1956; decommissioned at Green Cove Springs, FL, 12 December 1956; sold June 1960.

- Limitations
- Establishes identity, construction, service, and disposal. Contains no asbestos information whatsoever. Internal inconsistency: 'the day after commissioning she departed for New Orleans... arriving 29 January' - the 29 January arrival predates the 30 January commissioning (a typo, likely February); carried in gaps. Spec block reads 'cl. LST-511' though the hull is LST-542-class by NavSource/Wikipedia/class profile - carried in gaps.

- Ship-specific photographic/specification record: LST-542-class; WWII assignment LST Flotilla 32 / Group 95 / Division 189; awards (American Campaign, Asiatic-Pacific Campaign, WWII Victory, Navy Occupation Europe clasp, National Defense Service Medal); occupation service in Europe 7 June-20 September 1955; struck 1 November 1958. Specifications: 2 x General Motors 12-567A 900-hp diesels, single Falk main reduction gear, three 100-kW 230-V DC diesel-drive ship's service generators, 1,700 shp, 2 screws, twin rudders - a diesel plant with no boilers; 13 officers/104 enlisted + 16 officers/147 troops; armament 2 twin + 4 single 40mm and 12 x 20mm. Commanding-officer table: LT. Dicharry 30 Jan 1945-10 Dec 1945; LT. Kalafat to Mar 1946; LTjg. Cummins to 30 Jul 1946; LT. Finneran (later VADM) from 2 Feb 1951; LCDR. Leonard 1955-12 Dec 1956. Photo record includes Little Creek Jan 1954, 'Battle Cry' filming March 1954 (Vieques), and NHHC photo NH 86955 entering Grand Harbor, Malta, 14 June 1955.

- Limitations
- NavSource compiles official specifications, donated photographs, and veterans' records - secondary as transcription but the canonical amphibious-ship archive. Its timeline text prints commissioning as '30 June 1945' contradicting DANFS (30 January 1945) and its own CO table - see correction row. Its merchant-service chain is internally inconsistent (see ev-06). No asbestos content.

- NavSource timeline vs CO table; DANFS LST-1081 + Pima County entries; NavalCoverMuseum post-office line
- Finding type
- vessel_history
- Finding
- Commissioning-date conflict documented: NavSource timeline text reads 'Commissioned, USS LST-1081, 30 June 1945,' which would make the entire DANFS Pacific itinerary (Pearl Harbor arrival 4 April 1945) impossible; DANFS entries for LST-1081 and Pima County both give 30 January 1945, NavSource's own commanding-officer table starts LT. Dicharry 30 January 1945, and the ship's post office was established 20 February 1945 (NavalCoverMuseum). The 30 January 1945 date is carried; '30 June 1945' is a NavSource transcription error propagated by NavalCoverMuseum's table.

- Limitations
- Corrects a secondary-source transcription error against two DANFS entries and NavSource's own CO table; does not affect any asbestos-related content (there is none). DANFS's own 'arriving 29 January' pre-commissioning date is a separate internal inconsistency, carried in gaps.

- Merchant service and loss: after June 1960 Navy sale the hull passed through merchant hands - 518 N (U.S. Leasing Corp.), Baltic Ferry (Atlantic Steam Navigation Co., UK-flag drive-on freighter after Smith's Dock refit), Sable Ferry, and Nickel Ferry (Mareantes Armadora / Andy International, Panama flag; IMO 6604133; call sign HOFU). NavalCoverMuseum records 'Caught fire at La Union, El Salvador on 1 December 1979 and considered unrecoverable'; a NavSource photograph documents the Nickel Ferry beached in Costa Rica.

- Merchant crews; refit yard workers (Smith's Dock 1965, secondary)
- Limitations
- End-state detail mixes sources of unequal weight: NavalCoverMuseum is a hobbyist-maintained naval-cover archive (its dates partially echo NavSource's errors); the fuller merchant chain (518 N, 1965 ASN purchase, Smith's Dock refit, 1972 Sable Ferry, 1977 Nickel Ferry) rests on secondary literature summarized in the Wikipedia GA article and is not independently primary-verified; NavSource's own 'sold for scrapping 1973 Brownsville' line is internally contradicted. IMO/call sign carried from secondary sources. No asbestos content; the 1965 Smith's Dock refit's materials scope is unrecorded.

- Finding type
- gov_survey
- Finding
- GAO documented the Navy's asbestos-management posture: the Navy's 1975 policy removed and replaced with nonasbestos materials only insulation that was damaged or had to be removed for repairs, modified in 1979 to selectively replace asbestos insulation in high-maintenance areas; 'although all ships contain some asbestos in such components as clutches and electric cables' (Navy statement to GAO). Fieldwork yards were Long Beach and Norfolk Naval Shipyards.

- Limitations
- Program-level context, not hull-specific - this ship was sold out of Navy custody in 1960, nineteen years before the report, so the policies described largely postdate her service; it frames the era regime under which any retained insulation would have been managed. gao.gov blocked direct curl (403) on 2026-10-02; content verified via Firecrawl-rendered page incl. report first-page text.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - era-consistent presence is a reasonable inference but is not ship-proven. The hull's 1979 loss by fire in Central America means no present-day survey exists. Does not establish or defeat any claim of exposure or legal eligibility.
