Constitution Class Warship

The Constitution class was a crusier type starship very fast but weak. Until now I've designed a warship that takes the constitution class into war. First of her kind of Starfleet Command.

The Constitution class starships I know are:

USS ENTERPRISE NCC-1701 (Original Constitution class 1960's)
USS ENTERPRISE NCC-1701 (Original Constitution class Refitted in the film "The Motion Picture" 1980's)
USS ENTERPRISE NCC-1701-A (Constitution class Refitted until the film "The Undiscovered Country" late 1980's)
USS ENTERPRISE NCC-1701 (New Constitution class designed in 2009)

So then I came up with a new design.
