Recently there has been an increasing interest in military topics. Normally, Aviation does include military aircraft. Since e.g. this question got 4 close votes, and other missile-related questions get nominated as well, the opinion seems to be divided on missiles.
There was a brief related discussion on Meta 7 years ago, but it was for a very narrow question. I'd like to ask a broader one: should we consider missiles on topic, as a subset of aircraft, or off topic?
For on-topic, I see the point that cruise missiles are, for many intents, aircraft. They have similar major parts, fly the same way, and for large cruise missiles, are designed and built in part by the same companies, and the difference from UCAV comes down only to reusability.
For off-topic, there's the counterexamples of Space and Drones SE. It also risks an increased shift of military topics here (which isn't necessarily bad), with how much role missiles play in modern warfare.
However, there is no Military.SE, which would be the perfect fit. As the Aviation SE has a number of combat pilots and aerospace engineers, at this point, it's likely to have the most missile-related knowledge on the SE network.
What is the community's opinion on this? Should we establish a guideline, or leave it case-by case?
