[3]French Ministry of Culture, Maritime Archaeology of the Normandy Landings, “Transporting equipment” [other_primary]
- Locator
- Section “An LST that is difficult to identify,” page lines 23-25
- Finding type
- historical_record
- Finding
- The French Ministry of Culture page identifies the subject as LST 523 (a Landing Ship Tank), describes it as built in 1943, and reports that it struck a mine on 19 June 1944 while heading toward Utah Beach. It cautions that a nearby wreck commonly identified as LST 523 does not lie in the known accident area and may be a different, unidentified LST.

- Study period
- 1943-1944; wreck assessment described on page

- Limitations
- This records the bounded searches listed in search_ledger, not proof that asbestos was absent. Firecrawl was quota-blocked, the live NHHC DANFS and H-Gram URLs returned 404, and the CourtListener search was blocked before a result was returned. No inference is made from ship type, class, or era.
