This plane was the third working A-26 Prototype to be fully operational. In July of 1941 Douglas built a full-sized mock-up of the plane with dummy weapons to pitch to the Air Force. That initial display culminated in a contract for two operational prototypes - 41-19504 (The XA-26), and the 41-19505 (XA-26A). Later, the Air Force added a third prototype, the XA-26B (41-19588).

This plane was constructed with a solid nose and tested both with and without the 75mm cannon in the nose. However, it did not have the .50 caliber machine guns installed in the turrets.

There is less information on this particular plane than there is on the XA-26.

This plane served as a secondary prototype for what would become the B model Invader - those equipped with hard noses and heavy machine gun armament. One observable difference between the prototype models and the production models was the "propeller spinner" - the cone-shaped piece in the middle of the propeller blades. The prototype units were equipped with this feature, but none of the production models had them.

Differences between the XA-26B and the other XA prototypes were the addition of a third crew seat. The first two invaders were designed to be flown by a crew of two, but this one was deigned with three - Pilot, Navigator/Radioman, and Gunner.

Despite being constructed and test flown in 1942, the plane wasn't formally accepted by the Air Force until June, 1943.

Luckily, being a prototype model, there are some images of this plane.
