W.D. Sisson & his Cannon Ball diving submarine, 1917

Grolier Encyclopedia.  1957.
"Jesus, John, will you please stop that interminable whistling!"

I found this intriguing photo in an old encyclopedia I picked up.  A little online research unveiled more information.  It was so named because of its resemblance to a giant cannon ball.  The American inventor, W.D. Sisson, seems to have collaborated with the more famous  engineer, Simon Lake, on this vessel.  I can't find any information on whether it was ever actually used, or what its ultimate fate may have been.

MotorBoating, August 1918

The Engineer, November 2, 1917
