My rendituon of what if the US Army Air Force asked Douglas for a jet version of the A-26 rather than ugraded Pratt and Whitney double wasp radials. Unofficial designation for a proposed postwar production version of the A-26. It was to have a more powerful version of the Pratt & Whitney R-2800 radial engine and was to be fitted with such features as a raised pilot's cockpit canopy, an improved cockpit arrangement and wingtip drop tanks. If produced, the unglazed nose version would have been designated A-26G. However, in October 1945, the USAAF concluded that there were enough A-26 aircraft to meet postwar needs, consequently, the "A-26Z" version was not produced.
