Sorry, the comment form is closed at this time.
Is there any good reason why the vertical fin is like that?
It looks like somebody as inspired by Lippisch’s P-13.
Combination of inclined verticals for radar signature control and more volume for fuel, as I think range was really tight?
It makes for a lot of wetted area though.
This one would be interesting to see in a 3D drawing, as it’s hard to tell what it looks like from behind, and how the thick vertical fin fairs into the fuselage at the rear. They sure got fixated on the wingtip mounted engines.
