Background

About the ship

Following the denunciation of the Treaty of Versailles and the signing of the Anglo-German Naval Agreement, Germany went on with the development of the Deutschland-class "ironclads." More than twenty draft designs were considered. According to the requirements, their speed should have exceeded 34 knots, and one way to achieve that speed was to reduce the caliber of the main guns to 203 mm, especially since a 203 mm triple-gun turret had already been designed. The best option would have been to deploy three such turrets instead of two turrets with 283 mm guns.
