Easy to use, small, and accurate.
Key point: Tactical nuclear weapons are small and meant to be used against specific military targets, but any use would breach the nuclear threshold.
The United States maintains an extensive nuclear arsenal. According to the Federation of Atomic Scientists, the United States maintained an arsenal of over 7,200 nuclear bombs. Of those, more than 2,000 were deployed (1,900 strategic nuclear weapons and 180 non-strategic weapons).
America also maintains a plethora of delivery options for its nuclear bombs. As part of its nuclear triad, it maintains some 94 nuclear-capable bombers (B-2s and B-52s), over 400 Minuteman III ICBMs and 12 Ohio-class ballistic missile nuclear submarines. The latter are equipped with modern Trident II submarine-launched ballistic missiles, which are drastic improvements over their land-based competitors.
Indeed, as Keir Lieber and Daryl Press have noted, “In 1985, a single U.S. ICBM warhead had less than a 60 percent chance of destroying a typical silo… Today, a multiple-warhead attack on a single silo using a Trident II missile would have a roughly 99 percent chance of destroying it.”
Yet the most dangerous nuclear bomb in America’s arsenal may be the new B61-12.
Much has been written about the B61-12, most of which has focused on its enormous cost. And for good reason—it is the most expensive nuclear bomb project ever.
In terms of sheer destructive capability, the B61-12 is nowhere near America’s most dangerous nuclear weapon. Indeed, the bomb has a maximum yield of just 50-kilotons, the equivalent of 50,000 tons of TNT. By contrast, the B83 nuclear bomb has a maximum yield of 1.2 megatons (1,200 kilotons).
What makes the B61-12 bomb the most dangerous nuclear weapon in America’s arsenal is its usability. This usability derives from a combination of its accuracy and low-yield.Read full article
