A 37th Tactical Fighter Wing F-117 aircraft stands in Hangar 3. The aircraft is part of a display which also includes the B-2 bomber aircraft, F-22 tactical fighter aircraft and the advanced cruise missile. The exhibit has been assembled to provide members of Congress with an opportunity to view examples of stealth or "low observable" technology.

The Lockheed Martin F-22 Raptor is a fifth-generation, single-seat, twin-engine, all-weather stealth tactical fighter aircraft developed for the United States Air Force (USAF). The result of the USAF's Advanced Tactical Fighter (ATF) program, the aircraft was designed primarily as an air superiority fighter, but also with ground attack, electronic warfare, and signal intelligence capabilities. The prime contractor, Lockheed Martin, built most of the F-22's airframe and weapons systems and conducted final assembly, while Boeing provided the wings, aft fuselage, avionics integration, and training systems. USAF officials consider the F-22 a critical component of the service's tactical air power. Its combination of stealth, aerodynamic performance, and situational awareness enable unprecedented air combat capabilities and originally planned to buy a total of 750 aircrafts, but in 2009, the program was cut to 187 operational production aircraft due to high costs, a lack of clear air-to-air missions due to delays in Russian and Chinese fighter programs, a ban on exports, and development of the more versatile F-35. The last F-22 was delivered in 2012.
In 1964, Pyotr Ufimtsev, Russian mathematician, pioneered the idea that the level of the radar return from an airplane is related to its edge configuration, not its size. Basing on work by the German physicist Arnold Sommerfeld, Ufimtsev demonstrated that an aircraft radar signature can be reduced. By the 1970s, Lockheed analyst Denys Overholser found Ufimtsev's paper and F-117 Nighthawk was born as a black project, an ultra-secret Pentagon program. The F-117 has a radar cross-section of about 0.001 m2 (0.0108 sq ft). The F-117A carries no radar and whether it carries any radar detection equipment is classified. The F-117 also reduces infrared signature, lacks afterburners, and limited to subsonic speeds. However, the resulting design makes the aircraft aerodynamically unstable and requires constant flight corrections from a fly-by-wire flight system to maintain controlled flight. A pilot, who flew it while it was still a secret project, stated that when he first saw a photograph of the F-117, he "promptly giggled and thought to this clearly can't fly'". It has low engine thrust due to losses in the inlet and outlet, a low wing aspect ratio, and 50° wing sweep angle to deflect radar waves to the sides. Supercomputers made it possible for subsequent aircraft like the B-2 to use curved surfaces while maintaining stealth. The 558 Nighthawk's pilots called themselves "Bandits", such as "Bandit 17", that where 17 is a sequential order of their first flight in the F-117. The aircraft was in use during Panama invasion, the Gulf War in 1991 and was first shot down in Serbia during on 27 March 1999 by an antiquate Soviet-made SA-3s (S-125 "Neva" ) anti-aircraft missile. The pilot was recovered by a United States Air Force Pararescue team. According to Serbian anti-aircraft unit commander, they spotted the aircraft on the radar when its bomb-bay doors opened, raising its radar signature. The Serbs invited Russians to inspect the aircraft's remains, compromising the stealth technology. Although officially retired, the F-117 fleet remains intact and some of the aircraft are flown periodically as of 2019.
