- Finding type
- vessel_history
- Finding
- NHHC's DANFS entry for USS Willmarth (DE-638) records PC-1122 in Task Group 78.4 during the November 1944 Mapia and Asia Islands operation: PC-1122 joined the group for the sortie from Humboldt Bay, bombarded southern Pegun Island before the landing on 15 November, and, with Willmarth and HMS Ariadne, bombarded off Igi Island on 19 November before troops landed. The source confirms these operational references to PC-1122.

- Limitations
- This is an archived history of Willmarth that names PC-1122 in shared operations; the live NHHC URL returned 404 on 2026-10-03. It is not a PC-1122 material record and says nothing about asbestos, individual exposure, product identity, quantity, or eligibility.

- Limitations
- NavSource is a naval-history archive, not a Navy material survey. NARA independently confirms the commission date/logbook coverage, but the other dates, machinery detail, and complement were not independently verified in an official vessel record during this research. This source establishes no asbestos fact.

- GAO product-page highlights; full report PDF, introductory summary and 'Navy's Policy on Use of Asbestos'
- Finding type
- asbestos_application
- Finding
- GAO's 1979 Navy-wide review states that, according to the Navy, ships contained some asbestos in components including clutches and electric cables, and that thermal insulation had been the Navy's major shipboard asbestos use. The review concerns Navy policy and the Long Beach and Norfolk Naval Shipyards, not PC-1122.

- Limitations
- Navy-wide program context only. PC-1122 is not named; it does not establish that any listed material was installed aboard this diesel patrol craft, its location or condition, any exposure, causation, quantity, or legal eligibility. Direct automated access to the GAO product page returned HTTP 403, but the live GAO PDF/search result was reviewed.

- Finding type
- litigation_documented
- Finding
- No litigation classification is made. The required authenticated CourtListener exact-name opinion query for "USS PC-1122" was attempted through the fleet helper, but the API immediately reported daily quota exhaustion and a 13,936-second (~3.9-hour) wait. Per fleet guidance, no further exact-name, hull-number, docket, or opinion requests were made during this session.
