July 23, 2007 Just how important does someone have to be to have their own 30,000 pound bomb delivered by a billion dollar aircraft? We'll soon know. We have written about the Massive Penetrator weapon before here and detailed the awesome firepower and effectively infinite range of the US$1.157 billion B-2 here. The B-2 is a multi-role bomber capable of delivering both conventional and nuclear munitions through previously impenetrable defenses. The B-2’s low-observable technologies with high aerodynamic efficiency, large payload and an unrefueled range of approximately 6,000 nautical miles (9,600 kilometers) give it the unique ability to penetrate an enemy's most sophisticated defenses and threaten its most valued, and heavily defended, targets.
