Navis Neptun 20N Ersatz Yorck, a German battlecruiser designed to oppose HMS Hood 1/1250
A 1/1250 scale model in metal of the last German battlecruiser design of WW1. Based on the Mackenson class but with 15" guns and the funnels trunked together, the intention was to counter the British "Admiral" class, of which HMS Hood was the only one completed. Although the design staff continued to tweak the design into 1918, there was no realistic possibility of the ships being built and no names were allocated (Ersatz Yorck meaning replacement for the armoured cruiser SMS Yorck).
Two were ordered but never started.
