The Thresher

The thresher was a submarine that was sent out to destroy Soviet subs. It was said to be built with the most cutting edge technology but there were multiple problems that occurred to lead to the Thresher sinking. Before the it was sent out to sea the Thresher was sent out on test trials in the Atlantic and Caribbean Sea. When the Thresher sunk that was not the first time it had had problems while at port in  San Juan, Puerto Rico the reactor shut down and had to be partially evacuated until Cavalla came and provided power for the diesels. After that they continued to run trials.  Then when Thresher finally went out on her April 9, 1963 she sunk later figuring out to be due a failure in the joint in a salt water piping system.
