W 31Edit

Could you confirm what you mean by "W 31"? The designation can refer to multiple different topics across fields, and I want to make sure I write the article you want. Here are a couple of common possibilities, just to illustrate:

• W31 (thermonuclear warhead): A historical U.S. nuclear weapon design used on missiles during the Cold War. If this is the intended topic, I can provide a historically grounded article focusing on strategic context, deterrence, and policy debates, with a conservative perspective and high-level, non-operational detail.
• Another use: It could be a model designation, a catalog entry, a place, or something else entirely.

Please tell me which interpretation you want, or provide a brief description of what W 31 refers to, and I’ll draft the encyclopedia article in the requested format.
