These numbers are expected to increase inthe next fe\.r years by at least l+o per cent with continued MrRVine, introductionof ner,r cruise nissiles and. the tieployment of the Trident subrnarine. 39. The poner anal numb er of these strategic weapon6 is difficult to grasp, consider that s. single Poseiclon subtnaline nith its 15 MIRVed nissiles can deliver warheads to 160 separate targets; these ,varheads have a total explosive yieldof 6.1] l'{t.

analysis: The text appears to be discussing the military capabilities and nuclear weapons of the United States and the Soviet Union, specifically the numbers and types of weapons, their ranges, and their potential impact. The text also mentions the strategic and regional nuclear forces, as well as the explosive power of these weapons. Given the focus on military capabilities and nuclear weapons, it is likely that the text falls under the categories related to defense and security.
