The "American Citizen's Committee for Naval Excellence", a non-profit group of naval enthusiasts, presents the following designs to the US Naval Construction Board. ACCNE hopes the designs open discussion within Naval circles about how the USN can address the proliferation of so-called "large cruisers" (such as the Japanese Kongo-class, the Philippines' Samal and Bohol-classes, the Brazilian Rio de Janeiro-class, and the German Blucher-class, among others). ACCNE suggests that three units of this design could be built.
The design team set out to create a ship with a minimum speed of 33 knots, and attempted to keep down cost by using twin 12" turrets from the Delaware, Florida, or Wyoming class battleships. ACCNE is not aware of the status of these guns, so they might have been scrapped already. The new Dual-Purpose guns were also a requirement for the design.
[SIZE=1]ACCNE is a 501c3 not-for-profit organization completely made up by me for the purposes of presenting this design in as humorous a manner as possible.[/SIZE]
