[ 2] The F-117 Nighthawk was the first operational aircraft explicitly designed around stealth technology.
Stealth technology, also termed low observable technology ( LO technology ), is a sub-discipline of military tactics and passive and active electronic countermeasures, [ 1] which covers a range of methods used to make personnel, aircraft, ships, submarines, missiles, satellites, and ground vehicles less visible (ideally invisible) to radar ...
