The B-2 is a multi-role advanced technology bomber with stealth characteristics. The B-2's low observable, or stealth, characteristics give it the ability to penetrate an enemy's most sophisticated defenses. This low observability allows it to fly more flexible routes at higher altitudes, thus increasing its range and providing a better field of view for the crew and the aircraft's sensors. The low observability traits of the B-2 include greatly reduced infrared, acoustic, electromagnetic, visual and radar signatures. These signatures make it extremely difficult for even the most sophisticated defensive systems to detect, track and engage the bomber. Many aspects of the stealth feature remain classified. However, the B-2's composite materials, special coatings and flying wing design all contribute to its stealth.
The first B-2 rolled out of its hangar at Air Force Plant 42, Palmdale, Calif., in November 1988. Its first flight was July 17, 1989.
