The A-26B was the solid-nosed attack version of the Invader. The XA-26B-DE (41-19588) was the prototype of this particular version and was fitted with an unglazed nose housing a forward-firing 75-mm cannon. The crew consisted of pilot and gun loader/navigator seated side-by-side in the forward cockpit, and a gunner in the rear position behind the wing trailing edge. In addition, there was a "jump" seat behind the loader/navigator's position that could be used by an extra person who was going along for a ride. The rear gunner was provided with two viewing windows, one in the dorsal position and the other in the ventral position, and he aimed the guns remotely via an optical sighting system.
