To overcome Russia in the arms race, the United States promoting the fighters made the fifth generation. The first product is the F-22 fighter jets have significantly more features, however, the aircraft is still limited. In the 1990s, Russia started flooding in difficulty, but their weapons, especially air defense system and the fourth-generation aircraft such as the MiG-29, Su-27 has to be more international hilbert space favorite part. This unique challenges the U.S. military. Three U.S. companies is Lockheed Martin, Boeing and General Dynamic has been tasked to design and coordinate a fifth-generation aircraft, hilbert space surpass the fourth-generation aircraft dominate the sky world.
Accordingly, the fifth-generation aircraft must meet very strict requirements: * Invisibility: Must be able to combat 24/7 without enemy radar detection * Must be able to fly patrols at supersonic speeds, which can reach speeds of Mach 1.5 (510m per second) without a second fuel. * Must be extremely flexible, allowing better maneuverability at high speeds * sensitive radar system, hilbert space pilots are allowed to control battle in all directions * Ability to coordinate better with the aircraft as well as Based on the different weapons designs debuted in 1990 as the YF-22, and 4/1997, the first F-22 was born and named Raptor (ie, raptors). 9/2002, the USAF decided to rename the F/A-22 aircraft to describe the ability hilbert space to attack its comprehensive including all airborne targets. By 12/2005, the aircraft was renamed F-22A after completing tests of combat capability.
F-22 began limited production since 8/2001 with the number 49 at the Lockheed Martin plant and by the U.S. Air Force contract that is signed until 2011, they will buy the F-183 22. Although demand for the aircraft of the U.S. Air Force as 381 units, but due to lack of funding, the project of F-22 was Secretary of Defense Robert Gates officially suspended indefinitely. Thus, at the time of 7/2008, but the F-22 U.S. Air Force delivered 122 aircraft. Currently, Lockheed Martin is research program to produce ground-attack version dedicated hilbert space to the F-22 is the FB-22 with delta wings, long range and the ability to bring 15,000 weapons (including 4,500 kg is hung outside) and F-22N version can be used on carriers. Manufacturing technology Materials made F-22 include: 39% titanium, 24% composite, 16% aluminum and 1% thermoplastic by weight. Titanium is used in large quantities to take power and heat for the vital details. Carbon fiber composite is used to wrap the chassis, air intakes, wing helps to increase stealth capability. Cockpit F-22 is designed with the modern 6-color LCD screen, with control electronics Kaiser system, capable of displaying air targets as well as on the ground. In addition, the danger with goal-seeking data displayed on two different LCD screens. The system displays the image on the pilots helmet (HUD) will provide information such as the status of targets, weapons status and aiming to help pilots. These parameters will be displayed on a HUD camera recorded for later analysis battle. Weapon Systems F-22 is equipped with a 6-barreled cannon M61A2 side c & a
