SXB-355 "Trident" is a heavy ground attack plane / frontline bomber. Have two 57-mm cannon in engine nacelles and 2x20 in each turret (front and rear). Can carry over 2000 kg of ordnance.
I like the design, and a nice treetop level bombing run with flaps down is lovely to behold. I do wonder about the forward turret... I'm sure the pilot gets kicked in the head every time the gunner gets excited!
