[color=red]A new type of paint, or topcoat, increases the F-22 Raptor's stealthiness by reducing its vulnerability to infrared threats. To meet F-22 requirements, Boeing developed the topcoat to protect the aircraft against a broad range of wavelengths. The new paint replaces conventional topcoats, performing all the required environmentally protective functions while also reducing the aircraft's vulnerability to detection.[/color] The topcoat does not add to the F-22's weight, and provides performance enhancement at a very modest cost. It is applied in a two-tone camouflage design, patterned after the F-15 "Mod-Eagle" paint scheme. Development of the new topcoat began during the early stages of the F-22 program. Since that time, a small team at Boeing in Seattle has worked to refine the paint and improve its application characteristics in a production-level environment. Technicians at Lockheed Martin painted the first few aircraft by hand, however, robotic application is planned for future Raptors, including Raptor 04, which is scheduled to fly this summer. The topcoat application for each Raptor is expected to take one to two days.[/quote] Source :[url=http://www.globalsecurity.org/military/systems/aircraft/f-22-stealth.htm]Global Security[/url] 8)[/quote]
