Stealth aircraft are designed to be less detectable visually, thermally, audibly, and on radar, but are not invisible. The first prototypes were developed by Lockheed in the Have Blue project, with a unique design approach to reflect radar waves. Stealth aircraft are not designed for speed or maneuverability, but for stealth. The F117 Nighthawk was the first stealth aircraft, followed by the F-22 Raptor and B-2 Spirit bomber. These aircraft are primarily used for spying or initiating a first phase attack on enemy defenses.
Stealth airplanes are aircraft with special design features that make them less detectable visually, thermally, audibly, and on radar. They are by no means invisible, but they are much less identifiable than conventional aircraft. Such aircraft are part of an ongoing race between stealth technology and detection technology in warfare.
Stealth aircraft were initially developed by Lockheed in the Have Blue prototype project. The first two aircraft of this type flew between 1977 and 1979. The aircraft’s design approach was unique in that it centered around the engineering goal of reflecting radar waves perpendicularly, rather than making the aircraft streamlined. The reflection of radar waves is necessary to prevent radar waves from bouncing back for the enemy to detect on the ground. These airplanes are not designed for speed or maneuverability, but rather for stealth. Both early prototypes crashed due to their poor stability.
While usually painted black, this is not the optimal color for an aircraft to be stealthy. Counterintuitively, at the altitude at which most of these airplanes fly, a white ground would be the least visible. The black color is meant to make the aircraft look more intimidating.
Although stealth aircraft have become less stealthy in recent years due to improved radar scanning techniques, the countries of Russia and the United States continue to pursue their development. Theft detection technologies exist, but their effectiveness is uncertain, they require an abundance of computing power, and the detectors are not mobile.
Because they are designed to avoid detection, stealth aircraft would be powerless in a dogfight. Their primary purpose is to spy on or initiate a first phase attack on enemy defenses, softening them up for more conventional non-stealthy forces.
The first stealth aircraft was the F117 Nighthawk, a descendant of Lockheed’s Have Blue project. Others include the F-22 Raptor and the B-2 Spirit bomber, the most expensive aircraft ever built, at $2.2 billion. The latter was built for Cold War operations, capable of carrying both nuclear and conventional payloads, and would likely have been the primary bomber for nuclear strikes if war broke out between the US and USSR.
