Considered as the best Italian bomber of WW2, the Z.1007 was a mid-winged monoplane with a retractable tailwheel undercarriage. It had a crew of five, consisting of two pilots, a flight engineer, a radio operator and a bombardier/navigator. It was powered by three Piaggio P.XI RC.40 radial engines (a derivative of the French Gnome-Rhône 14K). A total of 660 Alciones were built and used.
