Apparently Burkhard Otto of jg300.de believes my accounts of the Dora-9 in JG 300 are 'fakes'. Despite the fact that they were first published in 2003 and based on material in the Lorant/Goyat history of the Geschwader!
Incidentally I do have a copy of Hubert Engst's (unpublished) 'memoir' written during 1966 for East German magazine 'Aero Sport'. In it he describes seeing "our last three Langnasen" getting airborne from Holzkirchen (a JG 300 airfield in southern Germany) for a transfer flight to Ainring during the last days of April 1945. He then 'spoils' it somewhat by referring to these 'long noses' as Ta 152s - which is obviously incorrect..
So just for Burkhard Otto, here's part 2 of the "Dora-9 in JG 300" Extract from the Lorant/Goyat history of JG 300 (my translation).
Major Rall’s Geschwaderstab of JG 300 underwent re-equipment with the Fw 190 D-9 from 21 April 1945. Two days later, four Focke-Wulf 190 D-9 Langnasen destined for II./JG 300 came into land at Holzkirchen. These aircraft, delivered with no spare parts, were powered by in-line Jumo 213 supercharged engines able to develop 1,900 hp rather than the 1,650 hp of the standard Jumo 213 at altitude. But it was at sea level that its performance was astonishing; with the methanol-water boost activated the speed of this thoroughbred was within a hairs breadth of 730 kph! Two of these superb aircraft apiece were allocated to the Gruppenstab and 7. Staffel. The fact that these aircraft were becoming available now just as Germany was sinking into chaos served only to reinforce a feeling of bitterness among the pilots. For want of sufficient fuel reserves, training flights in these “long-noses” were limited to a few circuits of the airfield for a handful of pilots selected by Oblt. Radener. The pilots of the Stab/JG 300 were often assigned to fly sorties with II./JG 300 according to requirements. One of these pilots was Uffz. Günter Ritzka, who recalled:
"..I had already had an opportunity to fly the Fw 190 D-9 before being assigned to Jagdgeschwader 300; I was probably the only Stab pilot familiar with the aircraft. During the last days of the war, I was detailed to ferry one of these Dora-9s from Altenburg to Zwickau. The machine had no armament. Shortly before reaching Zwickau, I came under fire, probably put up by our own flak whose crews were doubtless unfamiliar with the new fighter’s silhouette. As I overflew Zwickau, I could see that the airfield had been hit by a heavy air raid. Landing there was out of the question. I turned back to Altenburg and again came under heavy flak fire at the same location as on the inbound flight. I then realized that the front line had moved up considerably, which was obviously something that they were not aware of back in Altenburg… Suddenly, just as I had left the danger zone, my aircraft was caught in a burst of tracer fire which this time was zipping past me in the horizontal plane! I opened the throttle wide and hugging the ground tore back to Altenburg. I could see that I had been hit as oil was spattered all over my windscreen. I managed to put down at Altenburg with no further problems and taxied to the edge of the airfield. I clambered down from the cockpit and surveyed the undersides of the aircraft and counted five impacts. Just as I was assessing the damage, the air raid warning siren began to wail. I ran to the nearest foxhole. Two or three Thunderbolts flew two firing passes machine-gunning my Dora-9. It is entirely possible that the new Kommodore, Major Rall, flew the Fw 190 D-9. However I do not have any actual recollection of him doing so .."
