LOKHEED MARTIN F-22 RAPTOR:

In the previous session we have posted the first part of the information that was about the F-22 Raptor In the low observable technologies the improvement and Advances provided significantly improved the lethality and survivability against surface to surface threats and the air to air. The fighter F-22 Raptor brings stealth into the day, it not only enabling to protect itself but also protects the other assets.

As compared to the any other present time fighter jets engines the engine of the fighter F-22 rapter jet produce the more thrust. Without using the after burner the combination of the increased thrust and sleek aerodynamic design allows the F-22 to cruise at the supersonic air speeds (that is greater than 1.5 Mach) -- a characteristic that is known as the super cruise. Super cruise greatly expands the fighter jet F-22's operating envelope in both range and speed over the current time fighter jets, which must use the fuel consuming after burner to operate at supersonic speeds.

The sophisticated fighter jet F-22 aero design, advanced the controls of the flight, high thrust to weight ratio and thrust vectoring provide the capability to out maneuver all projected and the current fighter air craft. The design of the fighter jet F-22 Raptor has been extensively refined and tested aero dynamically during the processes of the development of the aircraft.

The fighter jet F-22's characteristics provide a synergistic effect ensuring F-22A lethality against the all advanced current time fighter aircraft threats. Combination of the stealth, super cruise drastically and integrated avionics shrinks surface to air missile engagement minimize and envelopes enemy capabilities to engage and track the fighter jet F-22. Combination of the reduced super cruise and observe-ability accentuates the advantage of the surprise in a tactical environment.

The fighter jet F-22 Raptor will have better maintainability and reliability than any other fighter aircraft in the history. Increased F-22 fighter jet maintainability and reliability pays off in less manpower required the ability to operate more efficiently and to fix the aircraft.

In 1986 the Advanced Tactical Fighter entered the validation and Demonstration phase. In late 1990 both the proto type aircraft YF-22 and YF-23 both completed their first flights. Ultimately the YF-22 fighter aircraft was selected as best fighting aircraft of the two mentioned above aircrafts and the advanced manufacturing development and engineering effort began in 1991 with the development contracts to Lockheed\Boeing (airframe) and whitney (engines) and Pratt. EMD included the system testing and extensive sub system as well as flight testing with the nine air craft at the base of the Edwards Air Force, Calif. In 1997 was the first EMD flight at the completion of its flight test life this fighting aircraft was used for live fire testing.

In 2001 the program received the approval to enter the low rates initial production. In 2004 Test evaluation and Initial operational by the Air Force evaluation centre and Operational Test was successfully completed. In 2005 Based on the maturity of the design and other factors the program received approval for the full rate of production. Training command and Air Education, Pacific Air Forces and Air Combat Command are the primary Air Force organizations flying the fighter jet F-22 Raptor. In December 2005 the fighter aircraft designation was the FA-22 for a short time before being renamed F-22A.
