- NavSource LSM-539 history block; indexed LSM table entries for LSM-539
- Finding type
- vessel_history
- Finding
- Available historical compilation identifies LSM-539 as an LSM-1-class hull built by Brown Shipbuilding Co., Houston; laid down 10 May 1945; launched 11 August 1945; commissioned 30 November 1945, with 1 December 1945 appearing in another compilation; decommissioned 24 May 1946 at Green Cove Springs, Florida; laid up in the Atlantic Reserve Fleet; transferred or loaned to Ecuador in January 1958 as Jambeli (LT-31); and scrapped in 1983.

- Population
- Brown Shipbuilding construction workers; U.S. Navy crew; Ecuadorian Navy crew; later dismantling workers
- Limitations
- The direct NavSource page returned HTTP 406 to the available direct fetch and the DANFS candidate URL returned 404; the historical milestones were checked against indexed search extracts and the LSM table, not a fully retrieved authoritative ship file. The 30 November/1 December commissioning discrepancy is retained. This row contains no asbestos finding.

[3]NavSource Online, LSM-1-class specification block on the live sister-hull archive page [other_primary]

- Specifications block: complement, troop accommodations, propulsion and generators
- Finding type
- vessel_history
- Finding
- The LSM-1-class specification block gives a design complement of 5 officers and 54 enlisted, troop accommodations of 2 officers and 46 enlisted, and a diesel propulsion plant of two GM 16-278A reversible engines rated at 1,440 BHP each, direct drive, twin propellers, and 2,800 shp. These are class/design specifications and are not a ship-specific crew manifest or engineering survey for LSM-539.

- Limitations
- The cited page is a sister-hull archive and class specification, not LSM-539's individual engineering or crew record. It supports design context only and contains no asbestos statement or ship-specific exposure evidence.

- Highlights: use of asbestos in Navy ships; policies for damaged and high-maintenance insulation
- Finding type
- asbestos_application
- Finding
- A 1945 U.S. Navy diesel landing ship falls within the WWII-era Navy shipbuilding period addressed by federal asbestos research. The applicable research pathways for this diesel design are machinery and exhaust insulation/lagging, gaskets, packing, electrical insulation, and brake linings; no source located for this record identifies any of those materials as installed aboard LSM-539.

- Population
- Navy shipyard workers and Navy ships in the program review
- Limitations
- GAO is program-level evidence based on fieldwork at Long Beach and Norfolk Naval Shipyards; it does not name LSM-539, Brown Shipbuilding, or any component aboard this hull. It does not establish material presence, quantity, condition, exposure, or causation for this vessel.

[5]National Archives, Researching Asbestos aboard US Naval Vessel up through 1961; batch search ledger [other_primary]

- NARA guide sections on RG 19 ship/hull correspondence, Ship General Information Books, and InSurv reports; search_ledger rows sl-01 through sl-10
- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos record was located in the sources searched: no asbestos survey, abatement contract, hazmat disclosure, material inventory, or verified litigation record naming USS LSM-539 was found. The National Archives guide identifies RG 19 Bureau of Ships correspondence, ship general information books, and Board of Inspection and Survey records as possible research paths for ship-specific Navy material history, but no LSM-539 file was retrieved.

- Limitations
- A negative public-source search does not prove absence of asbestos aboard. NARA's identified records were not surveyed in person and may contain relevant material or machinery documentation. CourtListener coverage is incomplete because the fleet limiter stopped the remaining required queries; this negative finding must not be read as a finding that no litigation exists.

- This is a zero-result indexed opinion search, not proof that no case exists. The remaining required exact-name docket and exact-hull opinion/docket requests were stopped by the authenticated fleet pacing limiter and are logged as blocked, not no-result.
