This paper describes the application progress of American fifth-generation fighter's cockpit transparency technology. The US first three generations fighters' cockpit transparency front windshield uses the reinforced inorganic glass/film/inorganic glass reinforced material structure, the front side is curved plexiglass windshield, and the rear part of the plexiglass has bubble canopy, and it only provides bulletproof function of the pilot-field observation without any feature film. The US fourth-generation fighter cockpit transparency plexiglass uses pieces/film/polycarbonate material laminate structure, with early version using wear resistant functional coating and the latter version using stealth features film. The US fifth-generation fighter cockpit transparency uses polycarbonate structure and plexiglass pieces/polycarbonate material laminate structure, and uses stealth features film. Stealth technology is developing in the direction of all-weather, omni-direction, ultra-wide stealth frequency band, and intelligence. Future fighters will have ultra-wideband electromagnetic, infrared, acoustic, laser, video and other omni-directional super stealth performance. It is of great significance to learn from the failure and successful experience of the United States in the field of fightercockpit transparent parts. To study the cockpit transparent parts technology suitable for Chinese fighters will help to improve the overall technical level of Chinese fighters.
