New CSN 2nd Class Cruiser

[Carthaginian]

The new Rattlesnake-class cruisers are designed to serve as light cruiser killers and cruiser group flagships. Though lightly armored, they are very large and survivable, and well armed. They also have an excellent top speed, making them capable of catching their smaller prey. The entire class is being built under order from France in Halifax, Nova Scotia and will be ready sometime in 1908.
