- Finding type
- vessel_history
- Finding
- Shipscribe's ARST-1 ship and class record identifies this hull as ex-LST-1098, redesignated ARST-1 in December 1944 (the construction table gives 14 December), laid down 6 December 1944 at Jeffersonville Boat & Machine, launched 27 January 1945, commissioned 5 June 1945, decommissioned 21 April 1947, struck 1 June 1973, and sold 29 January 1974. Its ship note records the ferry commission from 25 May to 5 June 1945, Manila Bay salvage operations from September 1945 to April 1946, and reserve status from 1946 to 1973.

- Limitations
- Shipscribe is a secondary compilation of Navy records rather than the underlying NARA/BuShips file. It supplies the most complete ship-specific chronology located; the underlying construction, conversion, reserve, and sale documents were not pulled. It documents no asbestos content, quantity, condition, or exposure.

- Laysan Island-class conversion and service paragraphs
- Finding type
- vessel_history
- Finding
- The U.S. Naval Institute's historical-fleet account identifies LSTs 1098-1100 as the three Laysan Island-class salvage craft tenders, states that they were redesigned as ARS(T)-1 through ARS(T)-3 before their December 1944 keels were laid at Jeffersonville, and describes their salvage-tender mission. It states that Laysan Island assisted in clearing wrecks primarily in Manila Bay from September 1945 to April 1946 before returning to the United States and decommissioning on 21 April 1947.

[5]NHHC DANFS search and live URL checks for Laysan Island and sister tenders Okala and Palmyra [nhhc_danfs]

- Finding
- A live NHHC DANFS page for Laysan Island was not located. Search results surfaced sister-tender pages for Okala (ARST-2) and Palmyra (ARST-3), but the cited URLs returned HTTP 404 when checked on 2026-10-02; they are recorded as an access gap and are not used as affirmative evidence for this hull.

[6]Batch search of NHHC/DANFS, NARA/official catalog leads, NPS/HAER, Navy registry/disposition leads, official/authoritative ship records, and CourtListener status as recorded in this atlas search ledger [other_primary]

- Finding type
- asbestos_application
- Finding
- No ship-specific asbestos survey, abatement contract, hazmat disclosure, material schedule, or other direct asbestos record for USS Laysan Island / ARST-1 / LST-1098 was located in the public sources searched. This is a negative finding about the located public record, not a finding that asbestos was absent from the hull.

- Limitations
- Public-record absence does not prove absence of asbestos aboard. The CourtListener search was incomplete because the authenticated helper's fleet-wide limiter required a stand-down; therefore litigation cannot be used as a complete negative. Undigitized BuShips, NARA, reserve-fleet, sale, and purchaser records may contain additional evidence.

[7]GAO, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (program-level Navy asbestos documentation) [gao]

- GAO product-page description of extensive Navy shipboard asbestos use and early-1970s substitution program
- Finding type
- asbestos_application
- Finding
- Class/era context only: a World War II-era diesel-powered Navy landing-ship conversion falls within the period in which shipboard insulation and related products could include diesel-exhaust and machinery insulation, gaskets, valve packing, deck coverings, accommodation insulation, electrical insulation, and crane/winch brake linings. These are possible application categories, not documented products aboard Laysan Island.

- Finding
- Era inference only: the ship's diesel propulsion and salvage-tender machinery create plausible locations for insulation, packing, gasket, deck-covering, electrical-insulation, and brake-lining materials used in the WWII period. No cited source names any such product aboard this hull.

[9]CourtListener API v4 via cl-auth-search.py; exact-name opinion request initiated, subsequent requests blocked by fleet limiter [court_record]
- Locator
- Authenticated helper stderr: fleet-wide request budget momentarily spent; session stopped per batch rule
- Finding type
- litigation_documented
- Finding
- The authenticated CourtListener helper initiated the exact-name opinion request for "USS Laysan Island" but returned the fleet-wide pacing stand-down before a result was received. The exact-name docket request and both opinion/docket searches for "LST-1098" were not completed. No litigation classification is made from the incomplete sweep.

- Limitations
- This is a process-status row, not a qualifying asbestos-litigation finding and not a no-result finding. The helper was authenticated and v4-only, but the fleet limiter prevented completion of the required exact-name-and-hull-number sweep. No allegation, discovery record, trial finding, or judgment is asserted.
