Hollande Types.

United States and Great Britain.

The age of the submarine is a long one going back to the ancient Greeks, but we will look at its early years from the late 19th Century to the early twentyeth. France, Germany and Italy developed their own versions almost totally separately from the first Holland prototypes.

But it is these eleven or so types that has gone on to influence all modern design, up until recently when the British Royal Navy is going with an advanced copy of an early French designed hull.

All submarines in some ways have their shape based on or around the Holland original, because this fish like structure works well under the water for speed and manoeuvrability. 

But the French design which was taken on by Soviet Russia and now several other navies has more to do with the ability to dive deeper, hiding being the new game in submarine warfare.
