Now largely forgotten, Simon Lake once rivaled John Holland as a leader in Submarine design. But...suppose...the idea of a wheeled
submarine had truly caught the imagination of the Admirals of the world? What would a Lake-influenced
Deutschland or
Surcouf have looked like? To take another tangent, take a look at Lake's last design, to be found here- ( along with all the rest of them. lake had some success designing boats for the US Navy. )

One last tangent- Suppose Lake's concept of diving chambers had been taken further. Whole platoons of aquatic infantry
rising from the surf on the beaches of the unsuspecting enemy's beaches....
