- vessel_history
- Finding
- The live NavSource archival page identifies USS LST-221 as an LST-1-class tank landing ship, laid down 9 March 1943 at Chicago Bridge and Iron Co., Seneca, Illinois; launched 7 August 1943; and commissioned 2 September 1943. It records Asiatic-Pacific operations at Kwajalein and Majuro, Eniwetok, Hollandia, Guam, and Okinawa; postwar Far East occupation service from 17 September 1945 to 16 February 1946; decommissioning on 6 May 1946; striking from the Naval Register on 3 July 1946; four World War II battle stars; and sale for non-self-propelled merchant service on 4 March 1948 to Port Houston Iron Works, Inc., Houston, Texas.

- Limitations
- NavSource is a volunteer-maintained archival compilation, not an official Navy registry. It supports the listed identity and chronology; it does not establish asbestos content, individual exposure, or causation.

[3]NavSource Online: Amphibious Photo Archive, USS LST-221 specifications block. [other_primary]

- Specifications block
- Finding type
- historical_record
- Finding
- The live NavSource specifications block for LST-221 reports two General Motors 12-567A diesel engines, single Falk main reduction gears, three diesel-drive 100-kilowatt ship-service generators, two propellers, twin rudders, and 1,700 shaft horsepower. It also displays 13 officers and 104 enlisted in its complement field, but that figure is not treated here as verified against DANFS/NHHC.

- Limitations
- The page is an archival compilation rather than a hull construction, personnel, or engineering record. The machinery description does not establish asbestos presence, quantity, condition, exposure, or causation; the displayed complement is not DANFS/NHHC-verified.

[4]Conservative synthesis from the live NavSource LST-221 machinery description and LST-1-class era analysis; no hull-specific asbestos document located. [other_primary]
- Locator
- NavSource specifications block; LST-1-class background
- Finding type
- asbestos_application
- Finding
- Era/design inference: a 1943 diesel-powered LST could have asbestos-relevant materials in diesel or exhaust insulation, gaskets and packing, deck coverings, accommodation or bulkhead insulation, and winch or crane brake linings. The diesel configuration reported by NavSource means boiler and steam-lagging pathways are not supported by that page.

- Limitations
- Inference only: no cited source names asbestos aboard LST-221 or identifies a product installed on this hull. It does not establish presence, absence, quantity, condition, individual exposure, or causation.

[5]NHHC DANFS candidate page for LST-221; live check returned HTTP 404 on 2026-10-02. NavSource archival page reviewed as the accessible historical fallback. [nhhc_danfs]

- Candidate DANFS URL; search ledger rows sl-uss-lst-221-lst221-01 through -07
- Finding type
- historical_record
- Finding
- The live NavSource page contains no asbestos statement. The current NHHC DANFS candidate URL returned HTTP 404, and the public-source search located no ship-specific asbestos survey, material schedule, abatement record, or hazmat disclosure for LST-221. This negative result does not establish that asbestos was absent.

- Limitations
- A negative public-source search is not proof of absence. The NHHC page was unavailable, Firecrawl was quota-blocked, NARA results were not located as digitized hull-specific records, and CourtListener coverage was incomplete. No exposure, causation, or legal-eligibility conclusion may be drawn.

[6]Authenticated CourtListener helper outputs retained as cl-uss-lst-221-opinion.json, cl-uss-lst-221-docket.json, cl-lst-221-opinion.json, and cl-lst-221-docket.json; all returned no result before the limiter wait was stopped. [court_record]

- Finding type
- historical_record
- Finding
- CourtListener exact-name and hull-number searches were attempted through the required authenticated v4 helper: USS LST-221 opinion, USS LST-221 docket, LST-221 opinion, and LST-221 docket. The helper authenticated the requests, but the fleet-wide pacing limiter caused them to hang without results; the requests were stopped. No qualifying asbestos litigation, other litigation, name collision, or no-result classification was established.
