- Finding type
- historical_record
- Finding
- The 1945 Bureau of Ships roster places LSM-158 within the LSM-150–187 group. The same volume identifies the LSM as a Landing Ship, Medium type and separately lists class machinery data for LSM groups.

- Limitations
- This is a documented research negative, not proof that no asbestos-containing material existed aboard. CourtListener and Firecrawl access gaps limit the completeness of the sweep; non-digitized Navy and shipyard records may contain additional evidence.
