During the Gulf war, much to the Pentagon’s chagrin, F-117 Stealth light bombers were detected by the British and the Iraqis with antiquated radar systems. During the bombing of Kosovo, one F-117 was shot down by Yugoslav anti-aircraft with a Russian made missile of 1964 vintage.
A second F-117, though not downed, was severely damaged during the conflict.

The point of stealth is that fewer of
your assets are destroyed in combat, it is not possible to guarantee that none of them are.
