- NavSource is a volunteer secondary compilation keyed to a veterans'-association history (Turner Publishing, 1997), not a primary registry - it generally tracks NVR/DANFS conventions but is not itself official. The stricken date and the Maritime Commission transfer date are explicitly 'unknown' in the source. No asbestos or material content. Battle-star and awards display is the extract's presentation, not verified here against the Navy awards database (awards.navy.mil unreachable this session).

- vessel_history
- Finding
- The Brown Shipbuilding production table lists LSM 8 as yard hull 113: laid down 14-Mar-44, launched 24-Apr-44, completed/delivered 26-May-44 - matching NavSource exactly - and records disposition 'Sold to Georgia Marine Salvage 1947, converted to barge Steven D, later Natcon 1 (ON 261812).' Yard history: Brown Shipbuilding was built in 1941 by George and Herman Brown at the junction of Green's Bayou and the Houston Ship Channel with $9M from the Navy; it built 254 LSMs among 359 total vessels in four years; leased to Todd Shipyards in 1949.

- Finding type

- Finding
- The official DANFS history of USS Clay (APA-39) records that at Lingayen Gulf, after unloading her troopers, Clay 'also embarked additional soldiers as well as 41 Army casualties transferred from LSM-8' before departing with TU 78.12.4 for Guadalcanal on 27 January 1945. This is an official-source confirmation that LSM-8 was present and operating in the Lingayen Gulf landings area during the Luzon operation, recovering casualties from the beachhead.

- The National Archives holds the wartime action report of Commander, LSM Group Seven for the Lingayen Gulf assault landings of 9-22 January 1945 and that group's June-August 1945 war diaries. The NHHC Pacific Fleet roster places LSM-8 in LSM Group Seven / Division Thirteen, so these are the records of this hull's own wartime formation for the operation she is documented to have taken part in.

[9]Era inference built on: NavSource specification block for this hull (two Fairbanks Morse 38D81/8X10 opposed-piston diesels, direct drive - no steam plant); GAO HRD-80-2 Navy asbestos-era documentation (ev-09); era-standard diesel-vessel application set [other_primary]

- Finding type
- asbestos_application
- Finding
- An LSM-1-class landing ship built at Brown Shipbuilding in spring 1944 sits inside the Navy's documented asbestos-use era. Because she was diesel-powered (direct-drive opposed-piston diesels, no boilers or turbines), the boiler/turbine steam-lagging pathway does not apply; era-standard applications aboard a diesel vessel of this type and period were thermal insulation, machinery and diesel-exhaust lagging, gaskets, valve packing, electrical insulation, and brake linings on deck machinery (winches, windlass), plus insulation felts in accommodation and galley spaces.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or verified litigation naming USS LSM-8 was found in the public sources searched (see search_ledger). CourtListener opinion search for 'LSM-8' returned a single name collision (Rios Sanchez v. Narvaez Calderon, P.R. Sup. Ct. 2004 - 'LSM' = Puerto Rico child-support statute), and 'USS LSM-8' returned zero opinions; RECAP docket searches returned 19 full-text string matches for 'LSM-8' in unrelated cases (criminal, bankruptcy, and product-liability dockets - none names the vessel) and zero for 'USS LSM-8'. A live-web asbestos/litigation sweep returned only unrelated noise (LSM8 gene, laboratory manuals); no law-firm or marketing page specific to this hull was located.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a 1944 diesel landing ship is era-consistent with retained asbestos materials. CourtListener opinion and RECAP docket indexes were both searched this session; PACER itself was not searched, and a complaint naming the hull could exist outside CourtListener coverage. The 182-image muster roll (NAID 126512019), COM LSM GR 7 action reports, and RG 24 deck logs are open archival leads. Does not establish or defeat any claim of exposure or legal eligibility.
