this would be a sweet ride !!!! heck i might even retire the Havoc if we get A 26,s

here are some armorment arangments i found
A new all-purpose nose was installed beginning with the A-26B-10-DL. Initially, the USAAF was undecided about exactly what armament this version should carry. As originally planned, it was expected that the A-26B would be fitted with a variety of alternate solid nose sections, and that one deemed to the best would be selected. Options that were tested on early A-26Bs included one 75-mm cannon to starboard and two 0.50-inch machine guns to port, one 75-mm cannon to starboard and one 37-mm cannon to port, 2 37-mm cannon with one on each side of the nose, or one 37 mm cannon to starboard and two 0.50-inch machine guns to port; four 0.50-inch guns starboard and one 37-mm cannon to port; or four 0.50-inch guns to starboard and two 0.50-in guns to port. Eventually at the end of 1944, the USAAF finally made up its mind and decided that the solid-nosed A-26B would have six machine guns. with 400 rounds per gun. The guns in the two turrets had 500 rounds each
Beginning with the A-26B-15, the forward-firing armament could be supplemented by eight 0.50-inch guns mounted in four twin packages underneath the outer wing panels
The forward-firing armament of the early A-26B was found to be insufficient, especially in the Pacific theatre. Beginning with the A-26B-50-DL production block, a new eight-gun nose was fitted, and six internally-mounted 0.50-inch guns were mounted in the outer wing panels so that bombs or rockets could be carried underneath the wings. However, the eight-gun nose and the internal wing guns were often retrofitted to earlier A-26B versions, so the mere presence of these features cannot be used as a positive identification feature.
In aircraft destined for service in the Pacific (-51-DL, -56-DL, -61-DL, and -66-DL), the remotely-controlled ventral turret was replaced by a 125-US gallon auxiliary tank for extra range
