F 22 Raptor certainly is the most modern and efficient fighter aircraft on this planet. It replaced the F15 Eagle, surpassing it at all and becoming the defender and guardian of the United States sky. F22 Raptor incorporates the main features of invisibility to radar and constant super cruise speed without using afterburner. F22 Raptor's radar is able to detect and attack multiple targets simultaneously a great distance. Carries all the weapons in hidden internal compartments, which increases its invisibility feature against the enemy radar. The first flight of an F22 Raptor was held in 1990 and for two decades no aircraft could match it. Today Russia and China are developing similar to Raptor aircrafts.
