FW 190 D-12
Fw 190 D-1117 Fw 190 D-11s were known to have been manufactured. This version was fitted with the uprated Jumo 213E series engine which was also used in the Ta-152 H series. Changes over the D-9 were the enlarged supercharger air intake on the starboard side cowling and the use of a wooden, broad-bladed VS 9 or 10 propeller unit utilizing three 9-27012 C-1 blades with a diameter of 3.6 m (11.8 ft). The 13 mm (.51 in) fuselage guns were removed, and the cowling redesigned by omitting the gun troughs and simplifying to a flat profile. Two 30 mm (1.18 in) MK 108 cannons were installed in the outer wings to complement the 20 mm MG 151s in the inboard positions. Of the 17 Dora-11s delivered, three can be accounted for. One, the best known, was Rote 4 (red 4) of JV 44's Platzschutz unit. Another, white chevron, was found at München-Riem, and may have served with JV 44 after serving at the Verbandsführerschule General der Jagdflieger (Training School for Unit Leaders) at Bad Wörishofen; it is not known if it was actually used operationally. A third, "white <61," was also found after the war at the Verbandsfuehrerschule General der Jagdflieger.[63]
While the D-11 was under manufacture, work started on the Fw 190 D-12 and D-13 models. The D-12 and D-13s were based on the D-11 design, however the D-12 and D-13 were fitted with Motorkanone nose cannons firing through the propeller hub (the D-12 would be fitted with a 30 mm (1.18 in) MK 108 cannon and the D-13 would be fitted with a 20 mm MG 151/20 cannon). There were three test aircraft built for the D-12 line, V63, V64 and V65 but no production aircraft were built.
