[5]U.S. Shipbuilding History (Colton), Kaiser Vancouver yard ledger: hull 156, LST 452, type LST, MC hull 972, keel 20-Jul-42, launch 10-Oct-42, delivery 16-Jan-43, disposition 'Scrapped 1947' [other_primary]

- Kaiser Vancouver page, yard ledger row 156
- Finding type
- historical_record
- Finding
- The Kaiser Vancouver build ledger confirms this hull as yard number 156 (Maritime Commission hull 972) with build dates matching DANFS/NavSource. The yard was an emergency yard built with $26mm in USMC funding, expanded from 10 to 12 ways, closed at the end of the war. The ledger's disposition entry reads 'Scrapped 1947', which conflicts with DANFS/NavSource ('sold 5 December 1947 to Bosey, Philippines'; 'fate unknown').

[6]Era inference built on: NavSource specifications for this hull (two GM 12-567A diesels, diesel-driven generators - no steam plant); DANFS construction dates (1942 build); GAO HRD-80-2 (Navy-wide asbestos insulation use era) [other_primary]

- Synthesis of ev-01, ev-02, and ev-06 (this record)
- Finding type
- asbestos_application
- Finding
- This hull was built in 1942 inside the Navy's documented asbestos-use era. Its diesel plant removes the boiler/turbine lagging pathway; the era-standard asbestos applications for a vessel of this type were thermal insulation, machinery and exhaust lagging, gaskets, valve packing, and electrical insulation. No source names this hull for any asbestos material.

- Limitations
- Class/design and era inference, not a hull record - no source inspected names LST-452 in connection with any asbestos product. Does not establish that asbestos was or was not installed aboard, nor quantity, nor present-day presence (hull sold out of U.S. hands in 1947).

- Finding
- GAO documented that the Navy used asbestos insulation extensively aboard ships and did not begin substituting alternative insulation materials until the early 1970s - spanning this hull's entire construction (1942) and service era (1943-46).

- Finding
- No qualifying litigation naming LST-452. Exact-phrase opinion search "LST-452": 0 results. Asbestos-qualified opinion search "LST-452" asbestos: 0 results. Unquoted token search LST-452: 118 opinion hits, full result set reviewed - every hit a name collision (state criminal, family, guardianship, tax, attorney-general, and consumer/commercial matters matching the tokens 'LST' and '452'; zero maritime, naval, or asbestos subject matter in case names, courts, or suit natures). Docket search "LST-452": 2 hits, both individual bankruptcies (In re Kuzy, Bankr. W.D. Pa. 18-21728, Ch. 11, terminated 2022; In re Sharma, Bankr. W.D. Pa. 20-22860, Ch. 7, terminated 2022) - name collisions, no maritime or asbestos nexus in the docket metadata.

- Limitations
- Negative finding for docketed litigation on CourtListener only; coverage is not exhaustive of all state trial courts, and a 1946-stricken hull sold to Philippine owners in 1947 is an unlikely asbestos-docket defendant. The 118 unquoted hits are token collisions, not vessel references - the exact-phrase search returning zero corroborates that no indexed opinion references 'LST-452' as a phrase.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - construction-era practice makes era materials plausible. Does not establish that asbestos is or is not present; does not establish or defeat any claim of exposure or legal eligibility. Deck logs and muster rolls (NARA, not digitized) were not examined.
