Although it may not be an American weapon, it has taken on some of the traits of one. This chinese stealth fighter has taken many ideas from US stealth bombers, and advanced it more so in military weaponry. The original stealth weapon they are copying it from was shot down, though. But, this is a good example of how American weaponry is still useful even if it was not all that successful.

Here is a link to an actual American stealth bomber incident. http://www.huffingtonpost.com/2011/03/20/us-libya-stealth-bombers-fighter-jets_n_838076.html
This tells you about an incident that happened with stealth bombers, and tells you some of the stealth bombers used in the incident. In this incident, there were 48 fatalities, and 150 wounded. Although not a great example American reasoning, it does show some uses of the stealth bomber.
