The Curtiss Super Hudson was a pusher biplane of the US air forces during the opening of the Great War. They were liked by pilots who flew them because it gave them a better view of the ground, and allowed for a machine gun to be mounted in front of the pilot. This was a tactical advantage over the Canadians who flew Avros whose only machine gun was operated by the rear passenger. Mainly flown for reconnaissance, they were modified to carry a camera man, who was also fitted out with a machine gun. As the war progressed, they were replaced by the Martin one-decker.
