- Finding
- NARA's digitized muster-roll collection (Records Relating to Muster Rolls of U.S. Navy Ships, Stations, and Other Naval Activities) contains no file unit titled to LSM-463, but the unit 'Amphibious Training Base, Galveston, TX. 2/29/44 to 7/2/45' (NAID 127308520, 116 images, digitized via the NARA-Ancestry partnership) surfaces on a quoted 'LSM-463' catalog search - i.e., the extracted text of the Galveston ATB roll references LSM-463, consistent with crew staging through the Eighth Naval District training base during this hull's January - July 1945 fitting-out window at nearby Houston. A second Galveston unit, 'Replacement Pool Amphibious Training Base, Galveston, Texas, 3/18/44-6/25/45' (NAID 191439824), also matches the query. Sister-hull muster rolls exist in the same collection (e.g., LSM-462 NAID 193111864, LSM-482 NAID 126649770, LSM-483 NAID 126649592, LSM-416 NAID 193163807) - the absence of an LSM-463-titled roll is a catalog-level gap, not proof none exists.

Whether the reference is a crew assignment block, a hull destination listing, or other content is unverified.

- GAO reviewed the Navy's efforts to protect workers from asbestos exposure (fieldwork at the Long Beach and Norfolk Naval Shipyards), covering 'the use of asbestos in Navy ships, the cost of removing asbestos from Navy ships, and compensation programs for asbestos-related disabilities.' Per the report highlights, the Navy's 1975 policy was to remove and replace with nonasbestos materials only insulation that was damaged or had to be removed to accomplish necessary repairs, modified in 1979 to include selectively replacing asbestos insulation in high-maintenance areas - establishing that asbestos insulation was in service aboard Navy ships of this hull's era and remained a managed material into the late 1970s.

- Limitations
- Negative at both index levels for the quoted hull number, and at opinion level for all name variants - but a docket-level (RECAP) full-text attachment could still name the hull inside a scan without index text. Absence of a located case does not prove no claimant was ever exposed aboard; it establishes only that no qualifying asbestos opinion or indexed docket names this hull as of 2026-10-01.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, ship's material schedule, or court record naming USS LSM-463 / USAT LSM-463 / USNS T-LSM-463 / RPS-BRP Isabela was found in the public sources searched (see search_ledger). NHHC has no DANFS entry for this hull (numbered LSMs generally not covered; candidate URL and both transcription mirrors 404). NVR excludes pre-1987 disposals per its own scope statement and carries no entry. MARAD's Vessel History Database returns 'No results found' (the hull was a Navy-to-Army-to-Navy-to-foreign transfer, never in MARAD custody). One auto-generated law-firm page exists for this hull (asbestos-ships.com/ships/uss-lsm-463, HTTP 200) - a banned-source-class template page asserting asbestos aboard with no primary sourcing; excluded by source policy.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a January-March 1945 Navy-contract-built amphibious hull is era-consistent with asbestos-containing materials, and the three-operator service chain plus undocumented 1989 disposal leave material fate unrecorded. Three NARA file units titled to the hull (drawings, material-inspection reports, casualty reports) are undigitized open leads. Does not establish presence or absence; does not establish or defeat any claim of exposure or legal eligibility.
