The Stearman Model X-100 was a competitor in an United States Army Air Corps competition for a twin-engined attack aircraft which (after redesigns) led to the Douglas A-20 Havoc, Martin A-22 Maryland and North American B-25 Mitchell.
[edit] Design and development
The X-100, designated XA-21 following purchase by the Army Air Corps, was a twin-engined high-winged monoplane of all metal construction. [1]It featured an unusual cockpit arrangement, much like those on most German World War II bombers designed during the war years, with a streamlined greenhouse canopy enclosing both the pilot and bombardier stations.[2]
[edit] Operational history
The XA-21 was first tested with the streamlined cockpit but this configuration was found to restrict the pilot's forward vision, and the aircraft was rebuilt with a conventional (stepped) nose and cockpit structure. [3]Although this change in the cockpit did not significantly affect performance, the XA-21 was not ordered into production.'[4]
The sole XA-21 had serial number 40-141.
