Portsmouth Naval Shipyard and Submarines

From Wikipedia.

In the last two blog entries I have written about Charles Sanna who was very involved with submarine construction and upkeep during World War II.  He also invented Swiss Miss Cocoa Mix.

And, Portsmouth Naval  Shipyard played a huge role in the U.S. submarine service in World War I and after the war right up through nuclear submarines in 1969.  One of the submarines launched there was the Thresher which was lost with all 129 aboard in 1963.

From 1942 until he left in February 1944, probably 35 submarines were built and launched at the Portsmouth Naval Shipyard.

Other ships of note launched at Portsmouth:  USS Congress (sunk by the CSS Virginia) and USS Kearsarge (sank the CSS Alabama).
