Developed in 1943, the XR-1A was contracted by the U.S. Army as the second prototype and improved version of its predecessor, the XR-1 (see image), in that the cockpit was equipped with more transparent paneling; futhermore, the observer is seated in front of the pilot, giving him high visibility.  Technical data remained constant [Ref 316].
