There is a difference between Ainu, which is supposed to be a hidden base not known to many and a Battleship that is there to serve a specific purpose, which will most likely be at least in the news for some time.
The problem with RPing that close to the base is the simple one that you as a KNF officer could find out about it if the GC would say anything.
I have seen the chat log and to be honest I wouldnt have raised a possible dangers suspicion in this case as well.
