Thesis: 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.
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.
