- Finding type
- vessel_history
- Finding
- The specialist Allied Warships record identifies USS LSM(R) 502 as a U.S. Navy LSM(R) 401-class medium landing ship (rocket), built by Brown Shipbuilding Co. in Houston, Texas; laid down 24 March 1945; launched 21 April 1945; commissioned 3 June 1945; decommissioned 4 May 1946; stricken 1 October 1958; and sold in 1959.

- Brown Shipbuilding construction trades; USS LSM(R) 502 crew, 1945-1946
- Limitations
- This specialist identity record is not a Navy archival record and does not provide a crew figure, operational narrative, asbestos information, or final-disposition detail beyond sale in 1959. It does not establish exposure, causation, or legal eligibility.

[3]NavSource Online, Landing Ship Medium / Landing Ship Medium (Rocket) index [other_primary]
- Locator
- Index entry at LSM(R)-502 Escalante River; type overview
- Finding type
- historical_record
- Finding
- NavSource's live Landing Ship Medium index identifies LSM(R)-502 as Escalante River within the LSM/LSM(R) archive and separately describes the LSM(R) type as a World War II rocket fire-support landing ship. The index independently confirms the canonical name-and-hull identity but does not supply a hull-specific history page that was accessible in this session.

- Limitations
- The index confirms identity and type only; it does not independently establish the dates, propulsion, complement, asbestos condition, or disposition carried in other fields. The expected individual NavSource URL returned HTTP 406/cache failure from available fetchers and is not cited as an accessible source.

- Finding type
- historical_record
- Finding
- The National Archives identifies Navy engineering drawings and specifications, including S39 insulation and lagging and S48 piping records, as research paths for vessel-specific asbestos documentation; it also identifies deck logs and related Navy records as archival leads. No LSM(R)-502 drawing, log, survey, or material record was retrieved.

- Finding
- GAO's Navy asbestos-program record describes Navy use of asbestos insulation and shipboard applications including gaskets, with policies beginning in 1975 and modified in 1979 to remove or replace some asbestos insulation. This is Navy-wide era context only.

- Helper stderr: fleet-wide request budget momentarily spent; exit code 2; no response body
- Finding type
- litigation_documented
- Finding
- CourtListener litigation classification could not be completed. The authenticated helper attempted the exact-name opinion query USS Escalante River, then returned the fleet-wide pacing stand-down before a result body. The exact hull-number searches and remaining opinion/docket searches were not run. No litigation hit, no-result finding, or litigation stage is asserted.
