VSKYLABS Boeing 'Bird Of Prey'



VSKYLABS Boeing 'Bird of Prey'
(VSKYLABS FICTIONAL stealth fighter version) 




The Boeing Bird of Prey was a black project aircraft, intended to demonstrate stealth technology. It was developed by McDonnell Douglas and Boeing in the 1990s. Funded by the company at a price of $67 million, it was a low cost program compared to many other programs of similar scale. It developed technology and materials which would later be used on Boeing's X-45 unmanned combat air vehicle. As an internal project, this aircraft was not given an X-plane designation. There are no public plans to make this a production aircraft. It is characterized as a technology demonstrator.

Design and development (Boeing prototype):
Development of the Bird of Prey began in 1992 by McDonnell Douglas's Phantom Works division for special projects. The aircraft's name is a reference to the Klingon Bird of Prey warship from the Star Trek television series. Phantom Works later became part of Boeing Integrated Defense Systems after the Boeing–McDonnell Douglas merger in 1997.


The first flight was in 1996, and 39 more were performed through the program's conclusion in 1999. The Bird of Prey is designed to prevent shadows and is believed to have been used to test active camouflage, which would involve its surfaces changing color or luminosity to match the surroundings.

Because it was a demonstration aircraft, the Bird of Prey used a commercial off-the-shelf turbofan engine and manual hydraulic controls rather than fly-by-wire. This shortened the development time and reduced the cost significantly (a production aircraft would have computerized controls).

The shape is aerodynamically stable enough to be flown without computer correction. Its aerodynamic stability is due to the same mechanisms found in canard aircraft such as the VariEze, the lift normally generated by the canards being provided by the chines (which therefore keeps the nose from sinking). This configuration, which can be stable without a horizontal tailplane and a conventional vertical rudder, is now a standard in modern stealth unmanned aerial vehicles such as the X-45 and X-47, tailless aircraft which use drag rudders (asymmetrically-used wingtip airbrakes) for rudder control.

The aircraft was made public on October 18, 2002, and was later put on display at the National Museum of the United States Air Force.

VSKYLABS stealth fighter version






VSKYLABS fictional version of the BIRD OF PREY:
The VSKYLABS fictional version of the BIRD OF PREY aircraft is different from the authentic prototype version. The stealth fighter version is heavier, has two non-afterburning engines. It is an aircraft carrier fighter equipped with an arresting hook and rigid landing gears. The original VSKYLABS stealth fighter carried two drop tanks, two air to air missiles and a single guided bomb.

The current version of the aircraft has a refurbished flight model, and it's default configuration is 'clean' (without any external payloads/weapons ect.). Reason for that is a very poor handling and performance qualities, mainly because of it's wings and fuselage layout of the original design, which are not suitable for adding payloads ahead of the Center of Gravity of the aircraft. Further more, the aircraft is flyable without the cannards, but with it's original weight only, which is very light.

The BIRD OF PREY stealth fighter uses all moving cannard surfaces. Their "job" is to produce extra lift and trim on heavy configuration, and to make it more agile and controllable at low airspeeds.
