Considering that we face no threat today similar to that of the Soviet Union 45 years ago, this should be more than adequate firepower for any defensive measure or, if need be, an offensive strike. And this would be true even if, against all expectations, our capacity was halved by an enemy’s surprise first strike. In addition, should we want to hit an enemy without destroying its society, the 311 weapons would be adequate for taking out a wide range of “hardened targets” like missile silos or command-and-control bunkers.

The key to shrinking our nuclear arsenal so radically would be dispersing the 311 weapons on land, at sea and on airplanes to get the maximum flexibility and survivability.

Ideally, 100 would be placed on single-warhead intercontinental ballistic missiles, like the Minuteman III systems now in service. These missiles, which have pinpoint accuracy, are scattered around the country in such a way that only one potential enemy, Russia, would have any chance of rendering the arsenal impotent with a surprise strike. (And it is likely that our unilateral cuts would entice Moscow, which has been retiring its systems at a fast clip in recent years, to follow suit.) Equally important, these missile sites are easily detected and monitored, which would reassure our friends and provide a credible threat to our enemies.

The sea leg of the plan would involve placing 24 Trident D-5 missiles, each with a single nuclear warhead, on each of our Ohio-class submarines. Today’s fleet of 14 can be cut to 12, with eight on patrol at a given time, together carrying 192 missiles ready to launch. The Tridents are extremely effective, as they can be moved around the globe on the submarines, cannot be easily detected, and present a risk to even hardened targets. And should any of our allies feel that our cuts in seaborne missiles are worrisome, we can remind them that the British and French will keep their complementary nuclear capabilities in the Atlantic.

Finally, for maximum flexibility in our nuclear arsenal, each of our B-2 stealth bombers could carry one air-launched nuclear cruise missile. While we have 20 such bombers, we assume that one would be undergoing repairs at any given time, giving us the final 19 warheads in our 311-missile plan. Our B-2 fleet is more than adequate for nuclear escalation control and political signaling, and giving it an exclusive role in our nuclear strategy would allow us to convert all our B-52H bombers to a conventional role, which is far more likely to be of use in our post-cold-war world.
