Military's video: B2 Stealth Bomber US Most Advanced Expensive Aircraft Military

B2 Stealth Bomber | US Most Advanced Expensive Aircraft | Military Stealth aircraft are designed to avoid detection using a variety of stealth technologies that reduce reflection/emission of radar, infrared,[1] visible light, radio-frequency (RF) spectrum, and audio, collectively known as stealth technology.[2] Development of stealth technology likely began in Germany during World War II, the prototyped Horten Ho 229 powered by twin BMW 003 jet engines being described as the first stealth aircraft.[3] Well-known modern examples of stealth of U.S. aircraft include the United States' F-117 Nighthawk (1981–2008), the B-2 Spirit, the F-22 Raptor,[4] and the F-35 Lightning II.[5] While no aircraft is totally invisible to radar, stealth aircraft make it more difficult for conventional radar to detect or track the aircraft effectively, increasing the odds of an aircraft successfully avoiding detection by enemy radar and/or avoiding being successfully targeted by radar guided weapons. Stealth is the combination of passive low observable (LO) features and active emitters such as Low Probability of Intercept Radars, radios and laser designators.
