The Stearman Model X-100 was a competitor in an Army Air Corps competition for a twin-engined attack aircraft which (after redesigns) lead to the A-20 Havoc, A-22 Maryland and B-25 Mitchell.
The X-100, designated XA-21 following purchase by the AAC, featured an unusual cockpit arrangement with a streamlined greenhouse canopy enclosing both the pilot and bombardier stations. This was found to restrict the pilot's forwards vision, and the aircraft was rebuilt with a conventional nose and cockpit structure. Although this did not significantly affect performance, the XA-21 was not ordered into production.
