I have a character in a world i am making along with a few others who are named after real life fighter jets both new and old however i was wondering if whatever i have made took off and got poplular would i have to change their names if the respective governments that commission these jets to be named something different or would i get sued if they don't like it or see it as effecting copyright or something?
Kind of new to this concept and i'm not even sure what i am scared about is possible but i want to make sure just before i go public with these characters.
