>>I love the idea of a stuka with a bomb bay!!
Yes! That in itself cleans the lines up a good bit, doesn't it?<<
That was kind of the point---take the "Stuka" look and take some of the angles and "awkwardness" out of it. The Suisei provided the smooth ventral contours and integrated lines from the intake back, and the Corsair wings still had that "cranked" look but gained "softer" contours, recessed oil coolers, and allowed retractable landing gear. The only other change was elimination of the "retro" support strut for the tailplane (taken off the later Bf-109s as well).
Also the idea was that this hybrid could be a "common" dive bomber for all Axis carrier forces in the Pacific (OF COURSE there were German carriers in the Pacific!! :) ). The Suisei was the fastest plane in Pacific skies for a while, but could not carry a larger bomb load than the fixed-landing gear "Val" it replaced (other than the bolted-on larger bombs on Kamikaze Suiseis). The Stuka was slow, but could carry a whopper bomb. So...cleaning up the Stuka made it fast enough to please the Japanese, and it could carry larger bombs, too!
PS--one of my future whifs will be a "Suisei-Kai"--a slightly larger version of the Suisei that WILL carry larger bombs (basically a Ryusei "Grace" retro-fitted with a low-wing and Suisei front end and cockpit.)
