Bird of Prey
The Bird of Prey is a single-seat stealth technology demonstrator used to test "low-observable" stealth techniques and new methods of aircraft design and construction. The secret Bird of Prey project ran from 1992 to 1999, and the aircraft first flew in the fall of 1996. The Bird of Prey was named for its resemblance to the Klingon spacecraft from the science fiction series Star Trek.
In depth
History & service
In its 38 flights, the Bird of Prey tested ways to make aircraft less observable to the eye and to radar. It also validated new ways to design and build aircraft using large single-piece composite structures, "virtual reality" computerized design and assembly, and disposable tooling. The Bird of Prey was revealed in 2002 because its design techniques had become standard practice -- Boeing used them in its X-32 Joint Strike Fighter demonstrators and later in its X-45A Unmanned Combat Air Vehicle prototype.
The aircraft demonstrates advanced stealth concepts, notably its "gapless" control surfaces that blend smoothly into the wings to reduce radar visibility, and an engine intake completely shielded from the front. The Bird of Prey, however, used some "off the shelf" technology to reduce costs and speed production. Its control system is all-manual with no computer assists, and the landing gear is adapted from Beech King Air and Queen Air aircraft.

Air power in a limited war
The Korean War brought early jet combat into the same theater as piston fighters, large bombers, helicopters, and transports. Different technologies served different needs. Fast fighters contested the air, while other aircraft attacked supply routes, supported troops, carried equipment, gathered information, and evacuated casualties. The mountainous terrain and severe weather made those tasks especially demanding.
The conflict also exposed the limits of air power used within a larger political and military struggle. Aircraft could damage bridges and transportation networks, but opposing forces adapted, repaired, dispersed, and moved under cover. Supporting troops required communications and coordination close to the ground. Maintaining operations depended on suitable bases and an extensive flow of supplies.
The surviving artifacts show why a gallery cannot be understood through jet fighters alone. A tent, vehicle, radio, flight nurse's equipment, or rescue helicopter belongs to the same operational history. The stories of individual airmen are compelling because they took place within that complicated setting. Cross-links to the Second World War and later Cold War galleries reveal both continuity and change: familiar aircraft found new roles, jet performance expanded, and rescue systems developed further. The war ended in an armistice, making its history one of service and sacrifice within an unresolved division as well as one of technological change.
