The Su-6 (M-71F) is equipped with a 37mm cannon as standard.
The Su-6 (AM-42) is not equipped with a cannon by default and can be equipped with a 23mm/37mm cannon.
And the Su-6 (M-71F) can carry all bombs without problems along with the 37mm cannon mounted as standard.
However, if the Su-6 (AM-42) is equipped with a 37mm cannon, it will not be able to load more than 100kg of bombs in the bomb bay and wing pylons.
Su-6 (M-71F), Equipped with 37mm as standard
Su-6 (AM-42), with 23mm
Su-6 (AM-42), with 37mm (Cannot be equipped)
I understand that the two aircraft are different only in the engine section, but the rest is the same.
I want to equip the Su-6 (AM-42) with a 100kg bomb and a 37mm cannon :(
