Trump Wants a New Low-Yield Nuclear Weapon. But the US Has Plenty Already.

The Trump administration’s Nuclear Posture Review (NPR), released in February of this year, calls attention to the composition of the US nuclear arsenal and its adequacy as a deterrent. The NPR calls for a new lower-yield submarine-launched nuclear warhead, arguing that it is needed to “counter any mistaken perception of an exploitable ‘gap’ in U.S. regional deterrence capabilities.” We decided to put together the chart in Fig. 1 to illustrate the range of nuclear weapons already available in the US arsenal.

One thing that this visual immediately makes clear is that it would be difficult to perceive any real gap in US capabilities—the existing arsenal certainly does not lack for nuclear options for any occasion.
