Nuclear Weapons Are Getting Less Predictable, and More Dangerous

By Patrick Tucker – On Tuesday, U.S. Secretary of State Mike Pompeo met his counterpart, Russian Foreign Minister Sergey Lavrov, to discuss, among many things, the prospect of a new, comprehensive nuclear-weapons treaty with Russia and China.

At the same time, the Pentagon is developing a new generation of nuclear weapons to keep up with cutting-edge missiles and warheads coming out of Moscow. If the administration fails in its ambitious renegotiation, the world is headed toward a new era of heightened nuclear tension not seen in decades.

That’s because these new weapons are eroding the idea of nuclear predictability.

Since the dawn of the nuclear era, the concept of the nuclear triad — bombers, submarines, and intercontinental ballistic missiles — created a shared set of expectations around what the start of a nuclear war would look like.

If you were in NORAD’s Cheyenne Mountain Complex in Colorado and you saw ICBMs headed toward the United States, you knew that a nuclear first strike was underway. The Soviets had a similar set of expectations, and this shared understanding created the delicate balance of deterrence — a balance that is becoming unsettled.

Start with Russia’s plans for new, more-maneuverable ICBMs. Such weapons have loosely been dubbed “hypersonic weapons” — something of a misnomer because all intercontinental ballistic missiles travel at hypersonic speeds of five or more times the speed of sound — and they create new problems for America’s defenders.

“As I stand here today, I don’t know what that solution set looks like,” Gen. Paul Selva, the Vice Chairman of the Joint Chiefs of Staff, said at an Air Force Association event in April. “If you’re going Mach 13 at the very northern edge of Hudson Bay, you have enough residual velocity to hit all 48 of the continential United States and all of Alaska. You can choose [to] point it left or right, and hit Maine or Alaska, or you can hit San Diego or Key West. That’s a monstrous problem.”
