In any battle, the key to victory is the ability to strike the enemy without them knowing what hit them. Within the US arsenal one such weapon can go into harm's way, deliver 40,000 pounds of either conventional or nuclear bombs, and slip away unobse... (more)rved--the B-2 Stealth Bomber. With its origins in single-wing experimentation in Germany in the 1930s, the B-2 was developed under a cloak of secrecy. But when that cloak was lifted, the world was awed by what stood before them. Able to fly over 6,000 miles without refueling, it can reach whatever target the US military wants to attack and deliver its awesome array of laser-guided weapons with pinpoint accuracy. Using state-of-the-art technology, including over 130 onboard computers, and shrouded by a mantle of stealth, it's undetectable by any radar.
