Pentagon Developing Prompt Global Strike Weapons as 'Non-Nuclear Deterrent'

"Nuclear" and "deterrence" have rolled off my tongue so many times that this WaPo headline struck me as supremely odd: "U.S. looks to nonnuclear weapons to use as deterrent."

As the White House pushes for cuts in the U.S. nuclear arsenal, the Pentagon is developing a weapon to help fill the gap: missiles armed with conventional warheads that could strike anywhere in the world in less than an hour.

U.S. military officials say the intercontinental ballistic missiles, known as Prompt Global Strike weapons, are a necessary new form of deterrence against terrorist networks and other adversaries. As envisioned, the conventional missiles would give the White House a fresh military option to consider in a crisis that would not result in a radioactive mushroom cloud.

The Prompt Global Strike program, which the Pentagon has been developing for several years, is already raising hackles in Moscow, where Russian officials predict it could trigger a nonnuclear arms race and complicate President Obama's long-term vision of ridding the world of nuclear weapons. U.S. military officials are also struggling to solve a separate major obstacle: the risk that Russia or China could mistake the launch of a conventional Prompt Global Strike missile for a nuclear one.

"World states will hardly accept a situation in which nuclear weapons disappear, but weapons that are no less destabilizing emerge in the hands of certain members of the international community," Russian Foreign Minister Sergei Lavrov told reporters Tuesday in Moscow.

The White House says that development of Prompt Global Strike is not affected by the new Strategic Arms Reduction Treaty (START), which Obama and Russian President Dmitry Medvedev are scheduled to sign Thursday in Prague. Analysts say, however, that any conventional ballistic missiles would count the same as nuclear ones under the treaty, which places new limits on each country's stockpile.

At first "non-nuclear deterrence" sounded kinda impotent, but perhaps I was mistaken.

See, Noah Shachtman, "Hypersonic Cruise Missile: America's New Global Strike Weapon - The mission: Attack anywhere in the world in less than an hour. But is the Pentagon's bold program a critical new weapon for hitting elusive targets, or a good way to set off a nuclear war?":

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.

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.

If Pentagon strategists get their way, there will be no place on the planet to hide from such an assault. The plan is part of a program — in slow development since the 1990s, and now quickly coalescing in military circles — called Prompt Global Strike. It will begin with modified Tridents. But eventually, Prompt Global Strike could encompass new generations of aircraft and armaments five times faster than anything in the current American arsenal. One candidate: the X-51 hypersonic cruise missile, which is designed to hit Mach 5 — roughly 3600 mph. The goal, according to the U.S. Strategic Command's deputy commander Lt. Gen. C. Robert Kehler, is "to strike virtually anywhere on the face of the Earth within 60 minutes."

The question is whether such an attack can be deployed without triggering World War III: Those tungsten-armed Tridents look, and fly, exactly like the deadliest weapons in the American nuclear arsenal.
