Cruisers that fought in WWII descended from sail-powered frigates of the 18th and 19th century. These vessels were designed for long-range independent operation (cruising) to gain information about the movement of an enemy, to raid the enemy's commerce, or to track down enemy commerce raiders. This title covers Germany's WWII Light and Heavy Cruisers of the Kriegsmarine. Included are the Light Cruisers Emden, Karlshuhe, Koln, Konigsberg, Leipzig and Nurnberg, and the Heavy Cruisers Admiral Hipper, Blucher, and Prinz Eugen. Also covers 'Z' Plan and Shipboard Aircraft.
