- Finding type
- vessel_history
- Finding
- NavSource identifies USS LSM-18 as an LSM-1-class landing ship medium, laid down 10 April 1944 at Brown Shipbuilding Co., Houston, Texas; launched 7 May 1944; and commissioned 14 June 1944 with Lieutenant William B. Wilder, USNR, in command. It records Asiatic-Pacific service in the Leyte, Ormoc, Lingayen Gulf, Mariveles-Corregidor, Mindanao, and Balikpapan operations; Far East occupation service from 2 to 23 September 1945; decommissioning at Terminal Island, California, on 26 March 1946; striking on 17 April 1946; and sale to A. G. Schoonmaker Co. of New York on 16 February 1947 for conversion to a barge.

- Limitations
- NavSource is a specialist historical compilation rather than an NHHC or NARA narrative. This page contains no asbestos, insulation, hazmat, condition, exposure, causation, or legal-eligibility information; later barge fate is not stated.

- Finding type
- vessel_history
- Finding
- NavSource's ship-specific specification block lists a complement of 5 officers and 54 enlisted, troop accommodations for 2 officers and 46 enlisted, and two Fairbanks Morse 38D81/8X10 reversible diesel engines with hydraulic clutch and direct drive, 1,440 BHP each at 720 rpm; twin propellers; 2,800 shp; and diesel-driven service generators (two 100 kW 450V AC and one 20 kW 120V DC). No boiler or steam turbine is listed in that specification block.

- Limitations
- These are the page's stated hull specifications and do not identify insulation or asbestos content. The absence of a listed boiler or turbine is not a complete engineering survey.

[4]Jacqueline Karnell Corn and Jennifer Starr, Historical perspective on asbestos: Policies and protective measures in World War II shipbuilding, American Journal of Industrial Medicine 11(3):359-373 (1987), PMID 3555021 [other_primary]

- PubMed abstract and bibliographic record, PMID 3555021
- Finding type
- asbestos_application
- Finding
- Corn and Starr's historical study documents extensive use of asbestos as fireproofing and insulating material in U.S. shipbuilding during World War II. For LSM-18, this supports only class/era context: possible applications include machinery or diesel-exhaust insulation, pipe insulation, gaskets, packing, electrical insulation, and fireproofing. The study does not name LSM-18 or establish that any listed product was installed aboard it.

- Program/era-level context, not ship-specific evidence. It does not establish product identity, quantity, location, condition, remaining material, individual exposure, causation, or legal eligibility aboard LSM-18.

[5]Batch-5985 public-source review: NavSource USS LSM-18 hull page; NHHC LCI(L)-759 DANFS entry and NH 102682 record; NHHC ship-history and NARA search targets [other_primary]

- Search ledger rows sl-uss-lsm-18-lsm18-01 through -07
- Finding type
- historical_record
- Finding
- No ship-specific asbestos survey, product inventory, abatement record, hazmat disclosure, or primary-source asbestos finding was located in the searched public sources for USS LSM-18. The located NavSource hull history and specifications and the NHHC Ormoc records contain no asbestos or insulation-material statement.

- Limitations
- A negative public-source search does not prove asbestos absence. Firecrawl was unavailable because its hosted keyless quota required a multi-hour stand-down; direct authoritative fallback research was used. This finding does not establish or defeat exposure, causation, or legal eligibility.

[6]Authenticated CourtListener v4 helper at /Users/charlesfletcher/devin-prompts/cl-auth-search.py; exact-name and exact-hull-number queries [court_record]
- Locator
- Authenticated helper stderr and request logs; no clean hull-specific result set returned after pacing began
- Finding type
- litigation_documented
- Finding
- The required authenticated CourtListener v4 helper was used for the exact-name and hull-number sweep. The exact-name docket request returned a broad result set with name/token collisions rather than a clean LSM-18 asbestos result; the exact-name opinion request and subsequent exact-hull requests entered the fleet pacing/stand-down state before usable result sets were returned. No qualifying asbestos litigation hit is asserted.

- Limitations
- This is an access-gap record, not a clean no-result finding. The broad returned docket set was not treated as ship litigation without hull-specific verification. No anonymous request, raw request, curl request, v3 API request, or retry loop was used; qualifying asbestos litigation remains unresolved.
