That’s Not All
The jet was an extremely secretive project. That was to be expected since the Advanced Development Projects of Lockheed were responsible for both the F-117 and the ultra-secret spy jet, the SR-71 Blackbird spy plane. The government also wants to keep things like this quiet.
Failed To Acknowledge
The USAF failed to acknowledge the existence of the F-117 until 1988. This was six years after Lockheed delivered the first completed aircraft. Two years after the acknowledgment, the USAF already had 59 F-117s in its arsenal, and they were ready to roll.
