USS Yorktown (CV-1940)


Back to US Navy ship list:

The four ship Yorktown class I am adding to the US Navy is to slot in between the improved Wasp class and the production line Essex class. So what improvements can I give the Wasp to make those ships even better. The first thing that comes to mind is an enclosed bow. Since the Treaties are now defunct there would be no need for weight saving, and these ships really can be 'improved'. A bigger hull for increased hangar capacity. Higher speed for increased flexibility. Better protection for increased survivability. Doing the enclosed bow for the Yorktown's, I may have to revisit the Essex class and do a bit of a rethink, redraw.

These four ships are still under construction when WW2 breaks out in 1939. The US Navy follows closely the way the Royal Navy carriers are used and what it can learn from the 'observers' it has on board Royal Navy ships. The Royal Navy ships confirm the ideas the that the US Navy has earmarked to put into the Yorktown class. Bigger, better , faster!

And that is what I have done. Longer, wider, an overall increase in size and displacement.
