- Finding
- NavSource's live USS LSM-253 hull page identifies this LSM-1-class landing ship medium as laid down 24 February 1944 at Federal Shipbuilding and Dry Dock Co., Newark, New Jersey; launched 17 April 1944; and commissioned 9 May 1944. It reports Asiatic-Pacific assignment, Okinawa Gunto operations 8-18 May 1945, Far East occupation service 2 September-9 December 1945, decommissioning 23 June 1947, sale to Foss Launch & Tug Co. on 23 December 1947, and final fate unknown. Its specification block gives a complement of 5 officers and 54 enlisted and two Fairbanks Morse diesel engines, 2,800 shp total.

[3]National Archives, Researching Asbestos aboard US Naval Vessel up through 1961 [other_primary]

- Beginning Research; RG 19 correspondence; General Information Books, Entry P 10; Ship Engineering Drawings discussion
- Finding type
- historical_record
- Finding
- The National Archives asbestos-research guide identifies Record Group 19 Bureau of Ships correspondence and Amphibious Vessel General Information Books (Entry P 10, 1940-1962) as possible research paths for a specific naval vessel, and identifies Hull Series engineering drawings by hull number, including S39 insulation and lagging and S48 piping when available. This is an archival lead for LSM-253; no LSM-253 record was requested or inspected.

- Researchers examining U.S. Navy materiel records through 1961
- Limitations
- The NARA guide is research guidance, not an LSM-253 material record and not evidence that asbestos was present aboard this hull. The relevant correspondence, GIBs, inspection reports, drawings, and specification files were not reviewed.

[4]Documented limited source-review negative; see search_ledger sl-uss-lsm-253-lsm253-01 through -06 [other_primary]
- Locator
- Reviewed live NavSource hull page and NARA guide; NHHC/DANFS and NVR direct access failed; Firecrawl quota was exhausted
- Finding type
- historical_record
- Finding
- No ship-specific asbestos survey, product inventory, abatement record, hazardous-material disclosure, condition report, or asbestos-containing product identification for USS LSM-253 was located in the limited public-source review. Ship-specific asbestos documentation and asbestos presence aboard remain unknown.

- A limited public-source negative is not proof that asbestos was absent. Non-digitized Bureau of Ships, shipyard, inspection, disposal, and purchaser records were not reviewed; no product, quantity, location, condition, exposure, causation, or legal eligibility is established.

[5]CourtListener API v4 via /Users/charlesfletcher/devin-prompts/cl-auth-search.py [court_record]

- search_ledger sl-uss-lsm-253-lsm253-07 and -08
- Finding type
- litigation_documented
- Finding
- The authenticated CourtListener API v4 sweep was not completed. The exact-hull-number docket search returned United States v. $41,273.16 in U.S. Currency, No. 1:14-cv-01822 (D. Md.), an unrelated federal civil-forfeiture matter classified as a name/text collision; it does not identify USS LSM-253 or asbestos. Exact-name and exact-hull-number opinion searches were initiated through the required helper, and an exact-name docket search reached the fleet-wide pacing limiter before a result was returned; the helper instructed the session not to retry in a loop.

- Limitations
- The returned civil-forfeiture docket is not ship or asbestos litigation. The incomplete authenticated sweep is not evidence that no qualifying litigation exists and is not a merits finding. No anonymous request, raw API request, or retry loop was used after the helper's pacing stand-down message.
