Actually, one question does come to mind: What are the massive helicopters on the stern of the H45? Or have I skipped a page or something earlier in the thread...
I never named them. The Weserflug VTOLs are known and at least a paper project.
The large helis are born from my head. They have intermeshing four-bladed rotors and are designed as heavy cargolifters. The rotors can get folded up, so the helis can get stored in the hanger. Because of the twin rotors no small aft rotor is needed (naturally...). It's a mix from a Sikorsky S-56-like hull and Kaman rotor tech. Would finally be very germanish.
