The Lockheed '''F-117A Nighthawk''' was the world's first operational aircraft based entirely on [[stealth technology]]. It was designed in the late 1970s by the highly creative [[Skunk Works]] engineering team at [[Lockheed Martin]], and first manufactured in 1981. It is flown exclusively by [[United States Air Force]]. They are nearly invulnerable, which softens their price tag of $40 million somewhat. | The Lockheed '''F-117A Nighthawk''' was the world's first operational aircraft based entirely on [[stealth technology]].
