- Finding
- USS LSM-309 was laid down 19 November 1944 at U.S. Navy Yard, Charleston, South Carolina; launched 9 December 1944; and commissioned 22 January 1945 at Amphibious Training Base, Little Creek, Virginia.

- Limitations
- This live volunteer hull page is a ship-specific historical compilation, not a government primary record; it supplies no asbestos, insulation-composition, hazmat, exposure, or causation finding. No individual DANFS entry or accessible NVR detail was located to independently verify these milestones.

- Hull-page Specifications block (Complement, Propulsion, and Ship's Service Generators)
- Finding type
- historical_record
- Finding
- The hull page lists two General Motors model 16-278A reversible diesel engines with hydraulic clutches and direct drive, 1,440 BHP each at 720 rpm, twin propellers, and 2,800 shp total; it also lists two diesel-driven 100-kW 450V AC generators, one diesel-driven 20-kW 120V DC generator, and a complement of five officers and 54 enlisted personnel.

- Population
- Ship's company; construction personnel
- Limitations
- The source documents diesel propulsion and its listed complement only; it does not identify asbestos-containing components. The complement has not been verified against DANFS/NHHC and is therefore not treated as independently confirmed crew data.

- Locator
- Report pp. 4-5, Background section
- Finding type
- environmental_record
- Finding
- NIOSH reported that Portsmouth Naval Shipyard's insulation shop had previously prepared and stored asbestos insulation; its workers manufactured pipe insulation for Navy ships and submarines and also performed rip-outs and pipe covering aboard those vessels.

- Population
- Portsmouth Naval Shipyard insulation-shop workers
- Limitations
- This is a different Navy shipyard and a later occupational-health evaluation; it is Navy shipboard-maintenance context only. It does not name LSM-309, Charleston Navy Yard, or the LSM-1 class, and does not establish asbestos aboard this hull, exposure, quantity, condition, or causation.

- NARA RG 19 guide; related RG 24/RG 38 references are archival leads
- Finding type
- historical_record
- Finding
- NARA's Record Group 19 guide identifies Bureau of Ships records as an archival route for ship design, construction, and technical records. Related deck logs are held in Record Group 24 and wartime operational records in Record Group 38; those record groups are leads for hull-specific construction, outfitting, and service documentation for LSM-309.

- Limitations
- Record-group mapping only. No box, file, drawing, or work package for LSM-309 was retrieved, so this does not establish that any hull-specific asbestos document exists or state its contents.

- Limitations
- This limited negative finding does not prove asbestos was absent. Firecrawl authoritative-source search was quota-blocked, NARA item-level records were not retrieved, and the authenticated CourtListener sweep was interrupted by the fleet pacing stand-down before all exact-name and exact-hull opinion/docket searches completed.
