- Finding
- DANFS record for this hull: laid down 1 July 1943 at Evansville, Ind., by Missouri Valley Bridge & Iron Co.; launched 8 September 1943; sponsored by Mrs. Henry Bohnsack; commissioned 23 October 1943, Lt. M. J. Prince, USNR, in command. Asiatic-Pacific theater; Marianas operation (Saipan June-July 1944; Tinian July 1944); Western Caroline Islands operation (southern Palau Islands September-October 1944). Redesignated IX-198 on 5 December 1944; decommissioned 20 January 1945; destroyed 16 May 1946; struck from the Navy list 19 June 1946. Three battle stars for WWII service as LST-129.

- historical_record
- Finding
- DANFS Cohasset (III) entry: 'The third Cohasset (IX-198) was so named and reclassified from LST-129 (q.v.) on 31 December 1944.' This conflicts with the DANFS LST-129 entry's redesignation date of 5 December 1944 - a documented internal discrepancy within DANFS itself; NavSource and the fleet lists follow the 5 December date.

United States naval vessels damaged by storm, Palau Islands, Caroline Islands: LST 129, LST 278, and LST 661, 06 d. 59'N., 134 d. 13'E.' - LST-129 was damaged by storm on 2 October 1944 in the Palau anchorage area alongside two other LSTs. The compiled ship list separately annotates LST-129 '2 Oct 44 (no details)' and lists 'IX-198 Cohassett [sic], 1944, 1625, Converted from LST.'

'Cohassett' spelling is a typographical variant in the IX table. No asbestos or materials content.

The Evansville yard was a purpose-built wartime 'cornfield' facility on the Ohio River that produced 171 LSTs; the plant was destroyed by fire in 1946.

- Finding
- Era/design inference for a diesel-powered LST built at a peak-asbestos-era wartime yard in 1943: NO boilers or steam plant (2x GM 12-567A diesels per the official BuShips design table) - the steam-lagging pathway does not apply; plausible asbestos applications on this type concentrate in diesel-engine and exhaust-system insulation, gaskets and packing throughout the engineering spaces, electrical insulation/cable, deck coverings including tank-deck surfaces, accommodation-space insulation, and brake/friction linings on winches and the stern-anchor windlass.

- Finding
- GAO documented that the Navy did not begin systematic asbestos-substitution policy until the early 1970s - more than 25 years after this hull was built and sunk. Construction-era material choices for a 1943 amphibious ship predate all Navy asbestos control programs.

- Finding
- CourtListener sweeps returned no qualifying asbestos litigation naming this hull: '"LST-129"' exact-phrase opinion search = 0 hits; '"LST-129"' RECAP docket search = 0 hits; '"Cohasset" asbestos' = 0 hits; '"IX-198"' = 2 hits, both Delaware Chancery appraisal cases (Nelson v. Frank E. Best Inc., 2000; Union Illinois v. Union Financial Group, 2004) whose 'IX-198' token is unrelated to the ship - classified name collisions; unquoted 'Cohasset' = 320 hits dominated by town-name collisions (municipal, zoning, and corporate entities for Cohasset MA / City of Cohasset MN) with no ship or asbestos case evident in the result set.

- Limitations
- CourtListener indexes published opinions and RECAP dockets only - a complaint settled or filed only in state court with no indexed text would not appear. Hull-number-only coverage is thin for WWII auxiliaries because plaintiffs' pleadings often name hulls inconsistently ('LST 129', 'U.S.S. LST-129'). The exact-phrase queries cover the canonical spellings; variant-token coverage limitation noted. The '"USS Cohasset"' phrase query repeatedly timed out at the API and is covered by the 'Cohasset' + asbestos qualified sweep (0 hits).

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, material schedule, or docketed case naming LST-129 or Cohasset (IX-198) was found in the public sources searched (see search_ledger). An asbestos-specific web search returned only encyclopedic/regurgitated ship-data pages with no asbestos content.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a 1943 wartime-built hull is era-consistent with installed asbestos-containing materials. The hull's destruction as a target in 1946 forecloses future survey; any asbestos aboard went down with the ship. Does not establish that asbestos was or was not present; does not establish or defeat any claim of exposure or legal eligibility.
