The first operation to use the F-117A was the Persian Gulf conflict. A number of F-117A flew in secret and accomplished a surprise attack on the communication institution and Air Force headquarters without loss of one F-117A even though it had the stiff defense. Furthermore the F-117A showed off to the public its attacking capability done by precision laser guided missile "GBU-27" through the media all over the world. The F-117A successfully proved the effectiveness of the stealth technology.
