On April 10, 1963, the USS Thresher (SSN 593) sank during deep-diving tests about 220 miles (350 km) east of Boston, Massachusetts, killing all 129 crew and shipyard personnel aboard. Her loss was a watershed for the U.S. Navy, leading to the implementation of a rigorous submarine safety program known as SUBSAFE. The first nuclear submarine lost at sea, Thresher was also the first of only two submarines that killed more than 100 people aboard; the other was the Russian Kursk, which sank with 118 aboard in 2000.
After hearing about the disaster, the young son of skipper CDR John Harvey made this crayon drawing of the sub lying on the ocean floor. The drawing is now in the collection of the U.S. Navy Museum in Washington, D.C.

I write to inform about the passing of a career cryptologist, Master Chief Petty Officer John L. Young, Jr. Much can be written about him, from his status as a very young (If not the youngest) Master Chief in the Navy, to his brilliant service with the 7th Fleet during the Vietnam War and subsequent to retirement, at the U.S. Commerce Department during the Reagan Administration as the leader of a renewed effort to strictly regulate export controls on high technology products. He was a man of many talents, from exotic cookery to restoration of antique Austin Healey motor cars. John’s first wife died but not before leaving a remarkable son, John L. Young, III, a honor graduate of the Naval Academy who completed an honors program at MIT and who was recently selected for promotion to Captain in the U.S. Navy.
If you want/need additional information, please email me at your convenience.
