- U.S. Navy crew and Fisher Boat Works construction personnel
- Limitations
- Ship-specific historical data, not asbestos evidence. The NHHC page was discoverable in the live search index but returned HTTP 404 when checked directly on 2026-10-03; NavSource's live page independently carries the same milestones. No PC-718 designation is adopted in this record; the batch fact-QA correction states that PC-718 never existed as a PC vessel.

- Finding type
- vessel_history
- Finding
- The live SC-718 photo archive records the hull's construction milestones, U.S. commissioning on 25 May 1943, transfer to Norway on 12 October 1945, later HNoMS Hitra identity, and a 1958 decommissioning date. It describes the vessel as a SC-497-class submarine chaser with two General Motors 16-184A diesel engines and two shafts, and lists a 28-person complement in its specification block.

- Limitations
- NavSource is an archival photo/reference page rather than a current Navy register. Its page still uses the superseded 'ex-PC-718' wording; that label is excluded from this record under the batch's 2026-09-29 fact-QA correction. The page does not document asbestos, exposure, or material condition.

- Locator

- Finding type
- historical_record
- Finding

- Limitations
- The feature documents the preserved Norwegian vessel and museum operation, not asbestos content or present material condition. It does not independently resolve the U.S. transfer-date discrepancy between wartime loan/operational accounts and the 12 October 1945 transfer date in DANFS/NavSource.

- No qualifying ship-specific asbestos record was located: no asbestos survey, abatement contract, hazmat disclosure, or public case record establishing asbestos aboard USS SC-718/HNoMS Hitra was found in the sources searched.

- Limitations
- This is a located-record negative, not proof that asbestos was absent. The public sources establish a WWII wooden diesel subchaser but do not identify installed insulation, gaskets, packing, or other fiber-containing products. CourtListener work was interrupted by the fleet pacing limiter after the first required base query; the incomplete litigation sweep is disclosed in the report and ledger.
