A Chilling Letter from the "Father of the Nuclear Submarine"

In 1963 Admiral Hyman Rickover, the "Father of the Nuclear Navy",  sent his usual sea trial report to shipyard executives and politicians.  However, on this day on May of 1963 it was not typical letter Rickover would send.   In this letter he addresses the recent tragic loss of the USS Thresher.  It is a chilling account of what happened just a few weeks earlier on April 10, 1963. This is the Original letter in my personal collection. Even though I collect and sell rare historical memorabilia and documents, I have always maintained this in my own personal collection.  Fellow submariners can only imagine the horrific fate our brave young brothers endured.
