The F-22 jet, built by Lockheed-Martin and designated the Raptor, is the most advanced and most expensive United States fighter aircraft to date. Its supercruise and
stealth capabilities, maneuverability and speed make it the most survivable fighter aircraft ever produced.
The F-22 jet was originally scheduled to begin production in 1996 with a total of 750 aircraft. That was subsequently reduced to 442
aircraft slated to enter service in 2003 and 2004. Then the Department of Defense reduced the number to 339 aircraft, then 277, and most recently to 187 aircraft.
The aircraft is a stealth fighter that is capable of speeds over Mach One without the use of afterburners. This is know as
supercruise. It enables the F-22 jet to travel long distances quickly, while conserving fuel. Using supercruise, fuel consumption of the
Raptor is among the lowest of any modern fighter. Yet, if necessary, the aircraft is capable of tremendous acceleration.
All weapons of the F-22 jet are carried internally. These include practically every modern weapon the USAF has.
Advanced controls enable the aircraft to have the maneuverability of the most advanced fighters in the world today.
The F-22 jet has much of the same stealth technology used in earlier aircraft.
Because it has a more stealth profile, less radar absorbing paints have to be used on it, saving
weight. Also, by eliminating the canopy frames, there is less chance of reflecting radar beams.
The new engines of the F-22 jet should last longer than conventional jet engines and they have far less
parts. They are also said to have excellent thrust to weight. The engines are controlled by two
computer systems, so that if one fails or is is put out of order, the other can continue functioning.
A "smokeless engine" feature helps keep the aircraft stealthy.
Aircraft maintenance is made easier with all components being easily accessible. Only six standard tools are used on the engine.
The first production fully vectorable nozzle is used on the engine. It can move up and down by twenty degrees.
Computers aboard check all systems so that the aircraft is self-diagnosing.
All instruments in the F-22 jet are digital. The cockpit can hold pilots of all sizes, from the very smallest to largest.
The aircraft is ready to taxi in about half a minute after the engine starts. To start the aircraft, the pilot turns on the
battery switch, puts the throttles to idle, and loads the mission into the computer. That's all!
Air to air weapons include up to eight of the latest missiles, with ground
attack weapons including JDAM's of up to 1,000 lbs. each, and air to ground missiles.
The F-22 jet is said to be the only modern fighter that is able to fire weapons while performing rolling maneuvers of up to 100 degrees
per second during extreme combat. A unique weapons launching system for the internal ordnance enables missiles to exit the
aircraft using hydraulics. A complete cycle for launching, including bay opening, the egress of the missile, and engine
start can take less than five seconds. The volumetric pressure on each missile during this process exceeds forty times the force of gravity at a speed of almost 30 fps.
The combat radius of the F-22 jet is enhanced by not having drag producing
ordnance on the exterior of the aircraft. Additional benefits from
having internal ordnance are increased maneuverability and speed. This
method of carrying ordnance is a vast improvement over other aircraft that carry their ordnance externally.
At this time a great deal of controversy surrounds the F-22 jet. Japan and Israel both want to
equip their air forces with the aircraft, but that is not permitted.
Many say the F-22 jet should be deployed in numbers greater than the production limit of 187
aircraft. They argue that although the F-22 jet is superior in virtually any combat environment to
any aircraft produced in the world, its numbers are simply not sufficient should the aircraft be needed in a two front conventional war.
Critics of continuing the F-22 jet production say that there is no need for an air superiority aircraft in today's world where anti terrorism, not
strategic battles, are a priority. They tell us that drones, electronics warfare aircraft, and weapons platform aircraft such as
the Lightning II are where the limited U.S. defense budget for aircraft should be spent.
We are told that the Lightning II will use virtually the same stealth technology for covering the aircraft that makes maintenance of the F-22 jet so costly. As of this writing the Lightning II is behind schedule
and over budget. Its speed, maneuverability, and weapons capacity is inferior to the F-22 jet.
Some argue that it is better to build more of the F-22 jet, that has been proven the best fighter aircraft in the world,
rather than gambling on unproven alternatives. Building more of the F-22 jet for the U.S., plus selling them to Allies would also lower the unit cost of the aircraft.
Russia is building a stealth fifth generation fighter aircraft, with the help of India, that will most likely be exported. It is
expected to be ready by 2016 and cost less than half as much as the F-22 jet.
The F-22 jet has had a number of issues with its oxygen system. The system is unique in that, rather than using an oxygen tank as on conventional jet fighters,
it uses compressed air from the engines. Problems have occurred when computers aboard the F-22 jet have turned off pilot oxygen in order to keep aircraft systems
from being damaged by engine system malfunctions.
The F-22 jet does not have an automated emergency oxygen system. The pilot is required to use about 40 lbs. of force to pull a ring
located under the seat in order to activate the emergency oxygen system. Some aviation experts have argued that activating the emergency oxygen system while doing an emergency
dive to an altitude where there is enough oxygen to breathe, all the while being oxygen deprived, would take a super-human effort.
The F-22 jet has been grounded several times while engineers have attempted to find the cause of the oxygen system failures. To date no cause has been found and the fighter jets are flying again.
Production of the F-22 jet ended at a total of 187 aircraft.

Jim
Young of Phelps, NY writes: "On our first trip to
the flying field with the Hanger 9 rc F-22 jet, Darrell
started
the engine and it sounded good. The airplane
took off with a
little climb, and Darrell brought it back
over the field for a
trim pass. "It really moves out!",
Darrell said,
as he pulled up in to a vertical roll. He made a slow fly
pass,
followed by a touch and go, where the rc F-22 jet prop
helped
with the field maintenance by mowing some weeds. Darrell put
his
airplane into a right spin, then changed to a left spin,
and
continued spinning right into the ground! He chopped
the
throttle just before his rc F-22 jet hit, and said, "I
didn't have it there at the last."
We trekked 300 yards through brush to collect the airplane.
"Must be my lucky day,"
said Darrell as he
surveyed scene. The main damage
was where the rc F-22 jet wing
tore loose from the fuselage. The
wing was cracked on the right
side.
Further inspection indicated that the aileron servo may
have
come loose during the spin. Another theory is that the model
may
have been tail heavy, snapping into a left spin
when up elevator
was used to try and break out of the right spin."
