- Finding
- NavSource records this hull as an LST-542-class tank landing ship laid down 2 September 1944 at Ambridge, Pennsylvania, by American Bridge Co.; launched 20 October 1944; and commissioned USS LST-834 on 10 November 1944 with Lt. Robert J. Bentley, USNR, in command. It records Asiatic-Pacific service with LST Flotilla 23, LST Group 67, and LST Division 133; participation in the Okinawa Gunto operation, 1-10 April 1945; occupation and China service from 2 September 1945 to 1 June 1946; decommissioning 13 September 1946; striking 8 October 1946; sale for scrapping 13 December 1947 to Kaiser Co., Inc., Seattle; and one World War II battle star.

- American Bridge construction trades (1944); Navy crew (1944-46)
- Limitations
- NavSource is a secondary compilation and the page does not document asbestos or material content. Its decommissioning date differs by one day from the DANFS date reported in an accessible secondary index; the conflict is carried in the record and gaps.

[6]Fleischer WE and Viles FJ Jr., A health survey of pipe covering operations in constructing naval vessels, Journal of Industrial Hygiene and Toxicology 28:9-16 (January 1946), PMID 21016030 [other_primary]

- NCBI/PubMed bibliographic record; full article not retrieved
- Finding type
- asbestos_application
- Finding
- Era context only: the 1946 U.S. Public Health Service survey titled A health survey of pipe covering operations in constructing naval vessels documents a wartime naval-construction setting in which pipe-covering work was studied. For an LST-542-class diesel ship, period applications could include machinery or exhaust insulation, pipe covering, gaskets, packing, electrical insulation, deck coverings, and friction materials; the survey does not name LST-834 or prove any listed material was aboard it.

[7]Authenticated CourtListener helper attempt, cl-auth-search.py, 2026-10-03 [court_record]
- Locator
- Helper output: DAILY QUOTA EXHAUSTED; wait 35403s (~9.8h)
- Finding type
- historical_record
- Finding
- No litigation result is reported. The required authenticated CourtListener exact-name opinion request for "USS LST-834" was blocked before results because the helper reported the fleet daily quota exhausted and instructed a roughly 9.8-hour stand-down; the hull-number and docket requests were not run.

- Limitations
- This is an access gap, not a no-result finding. No conclusion about qualifying asbestos litigation, exposure, products, causation, or disposition may be drawn until the exact-name and hull-number opinion and docket searches are completed after quota reset.

- Locator
- Search ledger rows sl-01 through sl-09 in this record
- Finding type
- historical_record
- Finding
- No ship-specific asbestos survey, abatement contract, hazmat disclosure, or product identification was located in the sources reached: the live NavSource hull page, NARA logbook index, accessible DANFS search results, and the reviewed era-context record. The required Firecrawl search was unavailable because its keyless MCP quota was exhausted with a multi-hour retry window.

- Limitations
- A record-search negative is not proof that asbestos was absent. Firecrawl access was blocked, CourtListener was blocked by daily quota, the underlying NARA logs were not read, and no conclusion about remaining material or exposure is supported.
