- Finding
- Yard-table row for this hull: LST 212, Landing Ship Tank for U.S. Navy - keel laid 12/6/42, launched 6/12/43, delivered 7/6/43; 188 days on the ways, 24 days in the water, 212 days total; disposition 'Sold 1947.' Yard context: the Navy requisitioned the Chicago Bridge facility at Seneca in 1942 and invested $6 million in improvements; the ~200-acre 'Prairie Shipyard' site sat on the east side of town on the Illinois River; after the war it was used for multiple purposes until sold to Union Mechling in 1949.

- State documentation of the builder yard: the 'Prairie Shipyard' in Seneca, Illinois, on the Illinois River built 157 LSTs for the U.S. military during WWII, 23 of which were directly involved in the D-Day assault at Normandy; by 1945 nearly 12,000 shipyard workers were employed there. The site is now the Shipyard Industrial Park within the Seneca Regional Port District (the district purchased the former shipyard property after GSA disposal).

- Finding
- Asbestos acknowledged at the builder yard's site: the 2006 purchase agreement for Lot 1 of Shipyard Industrial Park - the former Prairie Shipyard property where this hull was built - contains a seller representation that all improvements comply with building codes, 'provided that the slate siding and pipe insulation in the building previously constructed by the government may contain asbestos.' This is documentary acknowledgment of possible asbestos-containing construction materials in a government-built structure surviving on the wartime shipyard site.

- Two Veterans History Project collections are subject-indexed to this hull: the William L. Cornelius Collection (Lieutenant, USN, European Theater; 54-minute video interview) and the Daniel J. Mattingly Collection (Chief Petty Officer, USN; stations include Great Lakes IL, Portsmouth VA, Solomons MD, Annapolis MD; 40-minute video interview). An Indiana House Republicans press release (2019) notes Mattingly 'served in the U.S. Navy onboard the LST-212 during the war' at his French Legion of Honor award. These are firsthand crew narratives documenting service aboard this hull.

The Indiana press release associates Mattingly with 'Sicily - Normandy campaigns' - LST-212's documented credits are Convoy UGS-37 and Normandy only, and she commissioned 6 July 1943 (after the Sicily assault began 10 July), so any Sicily service would predate this hull; the press description is not carried as ship history.

- Finding
- Operational context for this hull's Convoy UGS-37 credit: the UGS-37 convoy, escorted by Task Force 65 units including Holder (DE-401), was followed 10-11 April 1944 by German aircraft along the Algerian coast and attacked by torpedo bombers just before midnight 11 April; Holder took an aerial torpedo amidships while screening, and the escorts 'drive[n] off the attackers without damage to the convoy.' LST-212's participation in UGS-37 (11-12 April 1944) is documented in her own campaign credits (ev-02).

[9]Era inference built on: NavSource LST-212 specifications (2 x GM 12-567A diesels, Falk gear, diesel-drive generators - no boilers); LST-1-class profile (lst-1-class.class.json, BuShips Ships' Data 1945 v2 machinery data); era amphibious-ship construction practice [other_primary]

- Finding type
- asbestos_application
- Finding
- Era/design inference for a diesel-powered LST built 1942-43: with no boilers or steam plant aboard, the asbestos-relevant systems were not boiler/turbine lagging but the era-standard applications of the type - diesel-engine and exhaust lagging, engine-room thermal/acoustic insulation, machinery gaskets and valve packing, deck coverings and tile, bulkhead and accommodation insulation, and winch/windlass brake linings. Wartime construction at a Navy-requisitioned yard inside the Navy's documented asbestos-use era (see ev-09) makes asbestos aboard a hull of this era and type a reasonable inference.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or verified litigation naming USS LST-212 was found in the public sources searched. CourtListener: the opinion index returned ZERO hits for 'LST-212'; the docket index returned one hit (SEC v. Badian, S.D.N.Y. 1:06-cv-02621) in which 'LST-212' appears inside a scanned SEC exhibit listing special-purpose vehicles - classified NAME COLLISION, not vessel-related and not asbestos litigation. The spaced-variant queries ('LST 212', opinion and docket) could not be run this session: the fleet-wide CourtListener pacing budget was engaged on every attempt - logged as blocked, not a negative result. The general web sweep surfaced no asbestos claim or litigation naming this hull; unusually, no law-firm listicle material was located either.

- Absence of a located public record does not prove absence of asbestos aboard - the litigation coverage is partial (spaced-variant queries unrun under fleet pacing) and the hull's post-1947 merchant career is undocumented. Deck logs, conversion-yard work records, and any merchant-registry file are undigitized leads. Does not establish or defeat any claim of exposure or legal eligibility.
