AIR CO-OPERATION FUTURE DEVELOPMENT Experience gained in the War of 1914-18 and since, under active service conditions, is limited. Thus the functions of aircraft in naval warfare are largely conjectural. They would appear, how ever, to depend on two factors, namely : the degree in ease of operation of carrier-borne aircraft, and the development in en durance and seaworthiness of the flying-boat type of aircraft.
