Caudron G.IV

Development and Operation

The Caudron G.IV was produced in response to an Aviation Militaire request for a more powerful Army Coordination aircraft capable of carrying a forward firing machine gun. The aircraft was a revision to the Caudron G.III. A second engine was added and the central nacelle was lengthened to allow for a nose gunner, and the number of rudders was increased from two to four. The armament consisted of a 7mm Hotchkiss or Lewis gun on a flexible mounting. The aircraft first flew in March 1915.

The United States Air Service of the A.E.F. purchased ten Caudron G.IV's for use as trainers at Tours. American cadets undergoing flight training at Tours leading to assignment as Army cooperation/reconnaissance/bombing pilots trained on this machine.
