Designed as a speculative venture this project was intended to fulfill Nordish requirements for a fast, multi-purpose escort vessel. Such vessels were seen as necessary to address the bloc obsolescence of the Nordish destroyer force. Due to changing requirements however, the project was shelved.

Among the several requests for proposals submitted by Peru in 1944 was one for a “pocket battleship” or armoured cruiser, featuring a heavy armament on a relatively light displacement. Novel features included the use of diesel engines on such a large warship, and the long range at speed. Nothing came of the proposal.

In response to the official design proposed by the Admiralstab the firm of Deschimag put forward its own proposal for a vessel for overseas service in the tropics. In the event the suggestion of constructing such vessels was abandoned by the Kriegsmarine and the Deschimag offered its design for export, but was unable to attract orders.
