I. Imagine being a foreign soldier guarding an important army depot. Five minutes pass quietly and quickly, and then in just 30 seconds you are blown away with your army depot. How could this have happened? Why didn't your air defense systems go off? Well, maybe it could've been the USAF F-117A Stealth Fighter. The F-117A, an expensive aircraft, is constructed from high-tech material, which results in effective, surprising attacks and a foundation for improvement on future air technology. II. F-117A developed and unveiled by US Air Force. A. After 10 years, the USAF has taken its covers off its top secret stealth fighter. B. Built by Lockheed Aeronautical Systems Co., the F-117A is described as a fighter craft. C. However, since it is by no means a dog fighter, the aircraft is primarily designed for surprise, prescision attacks on ground targets. III. Many new and high-tech equipment is used to create the unique aircraft. A. The dimensions for the single seater jet are 43 feet 4 inches for the wingspan, 65 feet 11 inches for its length, and 12 feet 5 inches for height. B. Its maximum wright is 52,500 lbs. C. Two General Electric F-404 turbo fan engines makeup the plane's powerplant. 1. They are covered with a radar-absorptive composite grid that blends into the lines of the wing. 2. Exhaust of the engines, which produce an estimated 12,000 lbs of thrust (about half of the F-15E powerplant), is deflected upward throught the grid, which creates a non-afterburning effect. D. The F-117A's control feature is a digital, quadruple redundant fly-by-wire. 1. No different from other modern fighters. 2. An onboard computer assists in flying (fly-by-wire) 3. 4 channels are programmed to perform the same functions. a. If 2 channels fail, the plane is still operable. b. It gives freedom to airframe designers to build higher performance levels. c. Secondly, it results in very precise control. E. It travels at high subsonic speed. F. The F-117A has unlimited range of operation due to air refueling techniques. G. The aircraft can support the most diverse weapons. 1. The bomb doors measure about 17 feet long, most likely carrying two 2000-lb lasr-guided penetration bombs or AGM-65 Maverick guided missles, since they are most commonly used for ground attacks. 2. However, they can carry HARM missles, which are enemy-radar tracking missle, or even PENGUINs, which are designed to skim the water for attack on missle boat. H. The one of the most significant parts in the plane is its materials. 1. The structure is primarily aluminum. 2. However, a skin of flat, rough Radar Absorbing Material (RAM) tiles, made of either a ferrite or polymer material, surrounds the aluminum. 3. The dual vertical tail fins of all the stealth fighters are being replaced with a thermoplastic graphite material, which provides greater reliability and longer life. I. The other significant part is its faceted design. 1. Any radar signals not absorbed by the craft's paint and skin would bounce back a signal that would appear to be unrecognizable "noise". 2. The leading edge of the wings, like every angle of the aircraft, tapers to a knife edge instead of the rounded form usually thought necessary to provide lift to an airplane. 3. A sawtooth design on the borders of the cockpit windows also is thought to scramble radar signals. 4. As a result of such design, the fighter is said to have a radar cross section (RCS) of about 0.01 sq meters, which is about the size of a bird. --However compare this to the 40 sq meter RCS pf a B-52 bomber. J. Each plane costs $42.6 million dollars, while the whole program spending of $6.56 billion. IV. Recent missions prove the F-117A to be effective. A. Due to its stealth qualities, it doesn't need to hug the ground to avoid radar dection. B. It can approach as high as 25,000 ft then drop down to deliver its payload. C. On the night of Dec. 19, 1989, six stealth fighters flew nonstop to Panama and back to US as part of the Panama invasion. 1. Four were committed to combat, which includes supporting an air drop of Army rangers. 2. Also they delivered a payload of 2000-lb bombs on Rio Hato, where an elite group of Noriega's forces were based. D. Also, F-117As destroyed an estimated 95% of every primary Desert Storm target in the Iraqi capital of Baghdad, according to American military planners. 1. They penetrated Baghdad's airspace despite the city's heavy defenses. 2. The planes also made accurate hits. a. One target was an Iraqi air force headquarters. 1. The multistory building was hit by a bomb dropped through the top of the structure. 2. The impact point was almost dead center in the roof. b. The concrete Iraqi air defense HQ was also damaged. 1. The bomb was guided through one of three air shafts in the roof. 2. It entered the shaft, followed by an explosion that blew out the building's forward air lock door. c. Brig. Gen. Glossen, USAF target planner, revealed that the F-117As successfully attacked the aircraft shelters at the Kirkuk, H2, and Talill airfields. V. Professor Drela believes that the shape is unnecessary in future stealth fighters. A. The shape resulted due to the limited ability of engineers back in the 1970s to model radar cross section. B. This severe shape takes its toll on aerodynamics and maneuverability. C. With better design tools and greater computers, engineers can now tackle the difficulty of predicting radar signatures of curved surfaces. -- Thus, the B-2 stealth bomber has taken on a more rounded shape. VI. High-Tech aircrafts are proven to have advantages over other countries, so the USA is trying to have the largest and most update weapons around. A. With the creation of the F-117A and its accomplishments, the USAF can now try and create bigger and more stealther weapons ever before. B. The F-117A may be the "weapon" that will separate the US from the other countries. Conclusion: VII. The US has now proven to be the leader of military power. America is now stockpiling for later use of their weapons. Also with their variety and update weapons, America CAN be the leader for a very long time. [-----] Total Time (speech): 7min and 14secs!
