The Engineering Division XCO-6 was an American two-seat observation biplane designed by the United States Army Engineering Division, only two were built and the type did not enter production.

Design and development

Two prototypes of the XCO-6 were built powered by a 420 hp inverted air-cooled V-1410 engine. One was tested at McCook Field and subsequently modified but no others were built.

Variants

;XCO-6 :Prototype two-seat single-engined observation biplane. ;XCO-6A :Proposed variant with the main fuel tanks moved into the upper wing, not built. ;XCO-6B :A XCO-6 modified with a change of engine to a 435 hp Liberty 12A engine. ;XCO-6C :XCO-6B modified with a larger propeller and changes to the landing gear.
