While the ST Aero MAV-1 is a low observable Unmanned Air Vehicle prototype developed between ST Aerospace and Defence Science and Technology Agency, what is designed to avoid detection using a variety of technologies that reduce reflection/emission of radar, infrared, visible light, radio-frequency (RF) spectrum, and audio?
Stealth aircraft Stealth aircraft are designed to avoid detection using a variety of technologies that reduce reflection/emission of radar, infrared, visible light, radio-frequency (RF) spectrum, and audio, collectively known as stealth technology. Development of stealth technology likely began in Germany during World War II, the prototyped Horten Ho 229 was designed for twin BMW 003 jet engines but finally powered by twin Junkers Jumo 004 jet engines being described as the first stealth aircraft. 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, and the F-35 Lightning II.
Raad (air defense system) Raad or Ra'd (Persian: رعد‎ ‎ , meaning "thunder") is an Iranian aerial defence system deployed in September 2012. The system is designed to enhance Iran's capabilities in terms of defense, and as a partner to Bavar 373 air defense system. According to Fars news agency the Raad, is more advanced than its Russian predecessor and is designed to confront fighter jets, cruise missiles, smart bombs, helicopters and drones. the system is also designed specially for US fighters. The system is equipped with "Taer" (Bird) missiles, which can trace and hit targets in ranges up to 50 km and in altitudes from 25 to 27 km (75,000 feet), Ra'd is ranked as a mid-range radar system and air defense system.
