Why did you think my last aircraft was "Ju 288G-1"?

Yep, you've got it, because there's a G-2!


(note the cartridge ejection, yes, that's gonna be a feature.)

When researching for the SG104 "Münchhausen", I found another very interesting gun called the Duesenkanone 280, or Düka 280.

It seems to be a repeater recoilless rifle of 28cm caliber, featuring better muzzle velocity (550 m/s instead of the 300m/s of the SG104), lighter warhed (400 kg instead of 700) and about 200mm of armor penetration (nearly 8 inches, enough to penetrate any ship's deck)

Since G-2 largely re-uses G-1's hull, it should be ready real soon, perhaps within next week or so.
