Security from the Grand Fork Air Force Base guards the 'Nighthawk' from tourists.
For stealth, the F-117A does not rely on radar for navigation or targeting. For navigation and weapon aiming, the aircraft is equipped with a forward-looking infrared (FLIR) and a downward-looking infrared (DLIR) with laser designator, supplied by Raytheon. The aircraft uses a Honeywell inertial navigation system.
The aircraft has multi-channel pilot static tubes installed in the nose. Multiple ports along the length of the tubes provide differential pressure readings. The flight control computers compare these in order to provide the aircraftÕs flight data.
