 The Prinz Adalbert class was a type of armored cruiser built for the Imperial German Navy in the early 1900s. Two ships of the class were built, Prinz Adalbert, and Friedrich Carl. Friedrich Carl was commissioned first, on 12 December 1903 and Prinz Adalbert followed on 12 January 1904. They were an improvement upon the design of the previous unique armored cruiser, Prinz Heinrich. Their armor belts were the same thickness but were more extensive than that of their predecessor. The two ships were also armed with four main guns in twin gun turrets, as opposed to the two single gun turrets of Prinz Heinrich.
