| | Angle constraint for nuclear-pumped X-ray laser weapons 180
Nuclear-pumped X-ray laser weapons are constrained to have an output beam divergence that is at least as great as a certain minimum value. Because this value is large, such weapons used for ballistic missile defence will require disturbingly high megatonnages in space: for example, a total of  73 megatons within range of 1,000 attacking missiles, with individual warheads up to 3.7 megatons or higher.
