The Caproni Ca.18 was a military reconnaissance aircraft built in Italy shortly prior to World War I. It became the first Italian-designed and -built aircraft to see service with the Italian armed forces. The Ca.18 was a monoplane of conventional configuration and fixed tailskid undercarriage. The wings were mounted to the fuselage with a bayonet fitting, to facilitate the rapid erection and dismantling of the aircraft.
