B-2 Spirit: $2.4 billion. The B-2 bomber was so costly that Congress cut its initial 1987 purchase order from 132 to 21. (A 2008 crash leaves the current number at 20.) The B-2 is hard to detect via infrared, acoustic, electromagnetic, visual or radar signals. This stealth capability makes it able to attack enemy targets with less fear of retaliation. "
