Crew survived for hours. Remarkable new information has emerged on the fate of the nuclear-powered attack submarine USS Thresher, also known by its hull number SSN-593, the lead submarine of its class, which was lost during trials east of Cape Cod, Massachusetts, in April 1963. While the official explanation states that the submarine sunk soon after getting into trouble, quickly claiming the lives of all 129 sailors and civilian technicians onboard, a newly unclassified report indicates that one submarine sent to search for it thought that at least some of the crew were still alive around 24 hours after the vessel was determined to have imploded.
The newly released information is found among 600 pages of documents, which constitute the most recent releases of information from the previously classified investigation into the loss of the Thresher. While the Navy began releasing these documents last year, on the orders of a U.S. District Court, these are the most recent. They seem to provide the first evidence that at least some of those searching for the Thresher believed there may have been crew members still alive on the submarine many hours after it was posted missing.
