Scorpion 2 on display in the Cold War Gallery at the National Museum of the U.S. Air Force. This is the second F-117A built that was modified for systems testing. It went to the museum in 1991 after its test program was completed with Air Force Systems Command. A total of 5 YF-117As and 59 F-117As were built between 1981 and 1990. A GBU is visible inside the bomb doors.
