Viribus Unitis Preliminary Project IV

The British were also strongly interested in the Austro-Hungarian dreadnought plans, as Koudelka was followed by an English spy at the time of his stay in Berlin.
At the beginning of the conversation, Koudelka, appearing on the 29th in his uniform, Tirpitz called him to the window and showed him the spy on the other side, then asked him to come in civilian the next day. (Those nasty British spies! :D )
Koudelka returned home with a detailed and extensive information of the meeting which, however, was partly accepted due to the secrecy involved and such the designers knew little about it. The Belt armour was indeed thickened with some calculations even showing 290 and 300mm Belt but in the end it was finalised with 280mm due to the capacity of the Austro-Hungarian shipyards (Displacement directly effects ship size)
