[8]Inference from the ship-specific NavSource diesel specification and the documented source-review negative [other_primary]

- NavSource propulsion/specification block; source-review negative documented in search ledger
- Finding type
- asbestos_application
- Finding
- No ship-specific asbestos survey, product inventory, abatement record, or condition report was located. Because LSM-47 was a World War II U.S. Navy diesel landing ship, machinery or diesel-exhaust insulation, gaskets, packing, electrical insulation, and deck covering are possible class/era application categories, but none is documented aboard this hull.

- Finding
- The authenticated CourtListener sweep found no qualifying asbestos litigation record for USS LSM-47. The exact-name opinion query '"USS LSM-47"' returned zero results; the hull-number opinion query 'LSM-47' returned 48 results (top 20 reviewed - all name/text collisions: 'LSM' construction companies, Leisure Sports Management, postal and unrelated matters); the hull-number docket query returned 2,274 results (top 10 reviewed - all PACER '-LSM' judge-initial case-number suffixes and document-47 fragments). Collision results were classified and excluded.

Result pages beyond the top-ranked hits reviewed were not individually opened; the text-based search surfaces only documents containing the query string, and a case referencing the vessel under a different rendering could evade it. The unrelated matches do not identify this vessel, its crew, or asbestos exposure aboard this hull.

[10]Texas Tech Vietnam Project, CDR Douglas Robertson biography page (now returns 404), weighed against the NavSource disposition chain [other_primary]
- Locator
- NavSource disposition lines and Foss-162 commercial-service photographs; Robertson page 404 at fetch time
- Finding type
- historical_record
- Finding
- A secondary military biography in the Texas Tech University Vietnam Project oral-history collection asserted a 1953-1957 executive-officer tour aboard 'LSM 47' at San Diego. The documented record shows the hull was sold in April 1948 and converted to the barge Foss 162 (commercial-service photographs exist), so the biography is treated as a hull-number collision or misprint in a secondary source rather than evidence of a post-1948 naval career.

- Limitations
- Flags and resolves an apparent secondary-source conflict: a recommissioned-in-the-1950s claim for 'LSM 47' cannot coexist with the photographed 1948 barge conversion and is not carried as vessel history. The biography may refer to a different hull number.

- HyperWar 'LSM DIVISION 26' row vs NavSource assignment lines
- Finding type
- vessel_history
- Finding
- NavSource places LSM-47 in 'LSM Division Twenty-Five' under LSM Group Thirteen commanded by LCDR T. F. Griswold, USNR. The official 1 May 1945 Pacific Fleet organization document instead places LSM 47 in LSM Division 26 under LSM Group 13 (ComLSMGrp 13, Lt. Cdr. C. L. Weigle). The official document is carried for the 1 May 1945 snapshot; the NavSource attribution may reflect an earlier wartime organization.
