A tip sets the plan in motion — a whispered warning of a North Korean nuclear launch, or of a shipment of biotoxins bound for a Hezbollah stronghold in Lebanon. Word races through the American intelligence network until it reaches U.S. Strategic Command headquarters, the Pentagon and, eventually, the White House. In the Pacific, a nuclear-powered Ohio class submarine surfaces, ready for the president's command to launch.More details over at Pop Mechanics.
When the order comes, the sub shoots a 65-ton Trident II ballistic missile into the sky. Within 2 minutes, the missile is traveling at more than 20,000 ft. per second. Up and over the oceans and out of the atmosphere it soars for thousands of miles. At the top of its parabola, hanging in space, the Trident's four warheads separate and begin their screaming descent down toward the planet. Traveling as fast as 13,000 mph, the warheads are filled with scored tungsten rods with twice the strength of steel. Just above the target, the warheads detonate, showering the area with thousands of rods-each one up to 12 times as destructive as a .50-caliber bullet. Anything within 3000 sq. ft. of this whirling, metallic storm is obliterated.
