[2]NavSource Online, Amphibious Photo Archive, USS LSM-22 (live page verified 2026-10-01 through Studio-side fetch after Firecrawl keyless quota exhaustion) [museum_official]

- vessel_history
- Finding
- NavSource identifies USS LSM-22 as an LSM-1-class landing ship medium, laid down 24 April 1944 at Brown Shipbuilding Co., Houston, Texas; launched 14 May 1944; and commissioned 21 June 1944 with Lt. William E. Rivinius, USNR, in command. It records Asiatic-Pacific campaigns at Leyte, Mindoro, Ormoc Bay, Lingayen Gulf, Mariveles-Corregidor, Mindanao, and Balikpapan; Far East occupation service from 9 September to 16 November 1945; decommissioning 27 May 1946; five World War II battle stars; and sale on 14 August 1947 to Sturgeon Bay Shipbuilding & Drydock Co., with later fate unknown. Its specification block identifies two Fairbanks Morse 38D81/8X10 reversible diesel engines with hydraulic clutch, direct drive, 1,440 BHP each at 720 rpm; twin propellers, 2,800 shp; and diesel-driven generators.

- Population
- Brown Shipbuilding construction workers (1944); ship's company (1944-1946); disposal personnel (1947)
- Limitations
- NavSource is a specialist volunteer archive rather than a Navy registry. The page supports the stated historical and machinery facts but does not identify asbestos-containing material, asbestos quantity, remaining material, individual exposure, causation, or legal eligibility. Its complement figure is not carried because this batch did not obtain DANFS/NHHC verification.

[3]National Archives, Ship Plan Index (live landing page verified 2026-10-01) [other_primary]
- Locator
- NARA Ship Plan Index landing page; record-level LSM-22 query not completed because the required Firecrawl connector was quota-blocked
- Finding type
- historical_record
- Finding
- The National Archives Ship Plan Index is the identified public research route for Bureau of Ships plan records. No record-level search result, ship-specific asbestos plan, survey, material inventory, or disposal file for LSM-22 was retrieved in this batch; RG 19 plan and specification records remain an archival lead.

- Study period
- 1944-1947
- Limitations
- This is an access/retrieval gap, not evidence that no plan or asbestos record exists. It does not establish asbestos presence or absence aboard this hull and does not substitute for a series-level archival request.

[4]CourtListener API v4 via authenticated /Users/charlesfletcher/devin-prompts/cl-auth-search.py: exact-name opinion request initiated; fleet pacing did not return results during this batch [court_record]
- Locator
- Authenticated helper stdout: 'authenticated request: type=o query_len=12' for exact name; no JSON result before fleet pacing wait
- Finding type
- historical_record
- Finding
- The required CourtListener litigation sweep was initiated through the authenticated v4 helper for the exact name "USS LSM-22" in the opinion corpus. The helper logged the authenticated request but fleet pacing did not return a result body before the research interval ended. The exact hull-number and docket-corpus requests were not sent into the fleet-wide pacing backlog. No CourtListener hit is classified as qualifying asbestos litigation, other litigation, or name collision because no result set was received.

- Population
- CourtListener opinion corpus; docket corpus not completed
- Limitations
- This is an incomplete sweep, not a no-result finding. No anonymous request, raw request, curl request, or v3 API request was made. Docket-corpus searches and result classification remain open; absence of a returned result cannot establish that qualifying litigation does not exist.

[5]Research sweep of NHHC, NavSource, NARA Ship Plan Index target, NVR, and CourtListener helper for ship-specific asbestos-relevant documentation [other_primary]
- Locator
- Search ledger rows sl-uss-lsm-22-lsm22-01 through -06
- Finding type
- asbestos_application
- Finding
- No ship-specific asbestos survey, product inventory, abatement record, hazmat disclosure, or qualifying primary-source exposure record was located for USS LSM-22. The hull's 1944 construction and documented diesel direct-drive plant supply class/era context only. The documented plant has no boilers or steam turbines, so no boiler/turbine-lagging pathway is asserted; asbestos aboard this hull remains unknown.

- Study period
- 1944-1947
- Population
- Construction workers (1944); crew (1944-1946); disposal personnel (1947)
- Limitations
- A negative public-source search does not prove asbestos absence. Construction era, builder, diesel machinery, general Navy asbestos use, and disposal cannot be converted into ship-specific product identification, quantity, remaining-material statement, exposure conclusion, causation, or legal eligibility. CourtListener and NARA portions were incomplete due fleet pacing and Firecrawl access gaps.
