F-117 Nighthawk – Top Speed: 617 mph
Made by the Lockheed Corporation, the F-117 Nighthawk is a now-retired stealth attack craft used by the United States military from the 1980’s until the mid-2000’s. The Nighthawk was the first stealth aircraft of its kind, developed based on the Lockheed Have Blue tech to execute exclusively stealth attack missions. The F-117 reached top speeds of around 617 mph or a little under one Mach.
Sixty-four F-117s were made and 59 were used active attack aircrafts. They cost about $111.2 million each to be made and maintained.
