| - A steath aircraft uses stealth technology, which includes special airframes and various other technologies to prevent the enemy from tracking it, making the aircraft "invisible" to radar, infrared, audio and radio frequency spectrum. Development of stealth technology likely began in Germany on World War II, while the Germans had noticed that flying wing designs have a lower radar cross section than conventional aircraft designs. Very advanced stealth aircraft include the United States' F-117 Nighthawk (1981–2008), the B-2 Spirit, the F-22 Raptor and F-35 Lightning II. While no aircraft is totally invisible to radar, stealth aircraft prevent conventional radar from detecting or tracking the aircraft effectively, reducing the odds of a successful attack, so that the stealth aircraft can strikie before its enemy can engage. Stealth comes from a combination of passive low observable (LO) features and active emitters such as Low Probability of Intercept Radars, radios and laser designators. These are usually combined with active defenses such as chaff, flares, and electronic countermeasures. It is accomplished by using a complex design philosophy to reduce the ability of an opponent's sensors to detect, track, or attack the stealth aircraft. This philosophy also takes into account the heat, sound, and other emissions of the aircraft as these can also be used to locate it. In other words, the principle of a stealth design "hide" the aircraft from the enemy while leaving a minimal footprint. Full-size stealth combat aircraft demonstrators have been flown by the United States (in 1977), Russia (in 2010) and China (in 2011), while the US Armed Forces has already adopted three stealth designs, and is preparing to adopt another, the F-35 Lightning II. Most recent fighter designs will at least claim to have some sort of stealth, low observable, reduced RCS or radar jamming capability, but as of yet there has been no actual air to air combat experience against stealth aircraft.
