Advance
Naval Base
A whole section of the coast has been enclosed and specialized for the construction and maintenance of our grand fleet. This small city of sailors, craftsmen, and engineers is capable of building entire navies by itself, making it one of the most important strategic centers of our country.
Advance tree
It has no requires, so the game files don’t say where this goes. When the game builds the 
Revolutions tree, it adds this at the end of a branch with room for it, in the same spot in every campaign.
