The most expensive weapon system of all times

Nevertheless, such advanced low observability by radar promises to reduce substantially the range at which an enemy’s acquisition radars can detect ingressing friendly aircraft from various look angles, as well as complicate the tracking of any F-22 or F-35 momentarily detected by enemy sensors. This will have the net effect of narrowing significantly any defender’s window of opportunity for successfully engaging and downing such aircraft. Thus, the F-22 and F-35 can operate in high-threat areas with less intense concern for surface-to-air defenses and can fly on headings and at altitudes aimed at maximizing opportunities for early target acquisition.
