F-22 Raptor

Program began F - 22 Raptor in the early eighties to develop fighter advanced tactical, this is a fighter first-generation fighter planes V and is designed to meet the Russian Air Force during the Cold War between America and the Soviet Union, with the fall of the Berlin Wall has expanded the role of tactical fighter developed to include the capabilities of multiple tasks such as tasks beating the precise objectives of the floor.

Technical descriptionAlukihid Martin f-22 Raptor, is a fighter aircraft with one seat and fitted with a twin-engine and has a high capacity maneuver over its counterparts from the fifth generation is using technology to sneak Stealth. It was designed initially air superiority fighter, but enjoyed the additional capabilities include ground attack, electronic warfare. The Lockheed Martin aerospace prime contractor for the project, which is responsible for the majority of the airframe, weapon systems and final assembly of the 22 - F. The partner Boeing space and defense industries supplying the wings, the fuselage at the rear, and avionics-ROMs, and training systems. And appointed different aircraft model F - 22 and F/A-22 during the years prior to entering the service USAF officially in December 2005 as F - 22A . Although the development of long and costly, the United States considers that the plane F - 22 crucial element of the strength of the U.S. tactical air, and claims that the plane is not matched by any fighter in the world, while Lockheed Martin says that mixing the components of phantom, speed and maneuverability with fighting capabilities of the land of Joe Joe Joe makes the best of the plane at all in the world today. Air Chief Marshal (Angus Houston), former president of the Australian Defence Force in 2004 that the "F - 22 will be a fighter jet the most exclusive at all." And led the high cost of the plane, and the apparent lack of missions fighting air due to the delay fighters fifth generation in Russia and China, and a ban on U.S. exports of aircraft, and continued development of the plans are cheaper and more versatile resulted ultimately in the production of the aircraft f-35, which is a less-expensive than the f-22 and can be exported to friendly countries. In April 2009, the production of 187 aircraft only and refused to Congress to fund any new purchase payments from the plane and stopped production at this number.

Strategic objectives of the F-22

Achieve control of the airspace of any battlefield through the skilful blending of stealth technologies and engines that support the long-range aviation, sensors and avionics, and maneuverability, agility and speed of movement and long-term, portable weapons inside. There are motors Pratt & Whitney F-119 - BW -100, enables it to fly to high altitudes does not compete and achieve speeds of offensive pressure and continued strong payment is superior to the fighter today.

Of weapons of Home - reinforcing

Major weapons platform carrying either: 6 medium-range missile guidance radar IM er -120 er or two IM 120. Two missiles 1000 - LB GBU -32 missile attack, the joint direct attack ground. It also carries two missiles Mtaatbaan temperature short-term er any M c -9, one on each side of the platform of weapons, and as a result can Raptor can fly at altitudes too high and too far, too fast with the proportion of the risk of a few that are exposed or intercepted and then hit full immunity against airborne targets and ground targets alike. This is a private U.S. military aircraft only.

Features
Plane F-22 air refueling

     4 columns of success - long-range flights - the speed and agility - stealth - and advanced avionics
     Ultrasound for long periods of time without having to run the secondary combustion devices afterburners or what is called the feature supercruise
     Ease of maintenance - requires periodic maintenance to make engine Pratt & Whitney F-119 - BW only 6 -100 commercially available tools
     Common integrated processor - CIB - the heart of integrated electronics suite, this super-computers can process 10.3 billion bytes per second.

Defects

Defects encountered in this plane are the disadvantages of cost and time rather than technical defects or workmanship, workmanship and the high cost of space in time of the aircraft maintenance are the most prominent flaws, A report from the Pentagon Bjabth the results of tests carried out by the ministry that the plane
     Cost 44 thousand dollars per flying hour
     30-hour maintenance per flying hour
     Low economic feasibility of production claiming the existence of competition from cheaper fighters and horses.
     Hull of the plane because of the erosion of its articles of high absorbency of the waves falling upon Alkashovah
     Exposed to damage if flew 1.7 hours without maintenance.
     Is redundant in the era of small wars and terrorist threats with reference to its potential in excess of the required.
