And in 1939, 15 MG 151 were delivered for the 0-series models, the only model apart from the V-series prototypes. An 1-series was planned, but they were scrapped at around 10% completion
If all of your primary and 2ndary sources state it is meant to be MG/FF’s in the nose then it’s meant to be MG/FF’s besides that you really should just be making a report of this. Not just a thread however to give credit where its due :Good Job :D
Well is it possible there were 2 He-100D-1’s? Ones that used the MG FF and ones that used the MG-151s? since there is a possibility. It would also explain why secondary sources are all saying MG FF’s and primaries are saying MG-151’s.
On the other hand, the Japanese documents in the original report do make mention of an Oerlikon motor cannon, this likely being the MG FF
I assume that the Japanese export aircraft were equipped with MG FF as the MG 151 was still only in preproduction, and this was then used in the secondary literature for the German models as well
Several prototype He 100 V series aircraft were sold to the Soviet Union, but according to Soviet documents, these did not have cannons installed in their noses. The Japanese Navy purchased pre-production models of the He 100 D-0 and MG 151 and conducted comparison tests with the Mitsubishi A6M2 to consider license production as interceptors for anti-bomber missions. The agreement was that the He 100 D-0 would be shipped from Germany to Japan first, and the MG 151 would be shipped later. It was called the Heinkel AXHe1 Model 100 High-Speed Fighter in Japan.
Dogfight
If both pilots are passive, the large speed difference means the battle remains undecided. If both are aggressive, the A6M2 wins. If the target is flying at speeds over 500 km/h, the He 100 D-0, with a top speed of 650 km/h, has the advantage. The He 100 D-0 is an interceptor designed for anti-bomber missions. In a dogfight with the A6M2, it cannot escape unless it has a speed difference of over 45 km/h. Sacrificing turn performance for a slight speed advantage is worthless.
Flight stability
The He 100 D-0 stalls abruptly, has overly sensitive elevators, heavy rudders, and lacks pitch balance at high speeds, making it feel dangerous to fly. This aircraft feels incomplete even as an anti-bomber interceptor. The A6M2 has no issues with stability in handling.
