But both the Bf 109 and the Sturmovik are among the most produced aircraft ever.
Sure, it could be considered the “best infantry-support airplane,” especially the G model with the twin 37 mm cannons. I’ve heard mixed reports regarding the “Trumpets of Jericho.” But the Stuka wasn’t the only exceptional attacker. The Il-2 was great, as was the P-47 Thunderbolt and Typhoon.
Infantry support mission makes me think of a close-support craft. Dive bombers (like the Ju 87) were for pinpoint attack, as an extension of artillery. Things like the Hs 129 was a purpose crafted tank-killer. But the Hs 123 may have been one of the best infantry support aircraft, at least in Europe. It was a biplane, light, quick-turning, and decently rugged.
The concept of “infantry support,” where some poor soldier in a foxhole calls in an airstrike, didn’t really exist until '44. The P-47 and Typhoon strikes in France, as well as the close-support work of the F4U in places like Okinawa, brought about the modern idea as we know it.
That being said, the Ju 87G was deadly in the right hands. And those hands were Hans-Ulrich Rudel. - the most dangerous man in an airplane!. Seriously, he sank a battleship.
