A brief article cannot thoroughly survey the vast scope of aeronautical development. During the war, improvements were made in almost everything involving flight and flight support: shipboard gear, such as arresting gear, barriers and barricades; safety and survival gear, including oxygen equipment, anti-G suits and life rafts; aircraft instruments; serological and meteorological equipment; photographic equipment and interpretation; Link trainers and target aircraft and kites for training; and construction materials and finishes. The list could go on and on. A follow-on half century of vigorous development of military technology has yielded few entirely new areas, notably lasers, transistors, infrared devices, supersonic aerodynamics and flight and high-altitude photography. Science and engineering have made great refinements in all areas of Naval Aviation, but in most respects, modern equipment can be traced to WW II antecedents.
