Is that a comparable cannon to the ones used on 109's/190's etc?
It's superior but, cannot be installed in a 109 and would have to be in a ventral pod in some cluncky way in a 190. It weighs about 1000lbs and the barrel alone is about 4ft, overall length about 13ft. It can handle 900m\s and faster rounds allowing it to reach out with distance. Where as the MG151\20 has a shorter barrel 3.5ft, overall length 6ft, weighs 92.5lbs and depending on the round 700-800 m\s.
