Two known to be in service with 17 built of D-13, D-12 canceled in favor of the D-13. One D-13 surrendered intact "Yellow 10". This is like the GV guys wanting a 500ft hill with a spawn over every field.
In all, the Ministry of Aviation called for 820 D-11 airframes to be built by Focke-Wulf Sorau, starting in early 1945, Fieseler Kassel was tasked to build 1,420 D-12s starting in the same time frame and the manufacture of the D-13 was passed to Arbeitsgruppe Roland [N 3] tasked with the construction of 1,060 airframes starting again in early 1945. For some unknown reason, production of the D-12 was cancelled in favour of the D-13 model. From evidence from the Oberkommando der Luftwaffe General Quartiermeister document Nr. 2766/45 of April 1945, it was known that 17 D-13s were more than likely built, but only two were known to be in service. A D-13 (Wk. Nr 836017) flown by the Geschwaderkommodore of JG 26, Franz Götz, an ace with 63 kills, was surrendered to the British at Flensburg, Northern Germany in May 1945.[55] As noted previously, this aircraft is still in existence, painted in its original colour scheme as Yellow 10 of 6 Staffel/JG 26, is thought to be airworthy and is currently located in the Flying Heritage Collection at Paine Field in Everett, Washington. This aircraft is one of the few existing Fw 190s with a provenance that can be traced continuously from its manufacture to the present time.[56]
