the problem with the nav buoy is that the ships don't target it at all. Unfortunately, ramming it is a bit fiddly, because I usually limit ship class to destroyer-class or lower. With infinite resources for all. That means there are many neverending battles. Yeah, so please take out the nav buoy for facilities build mode. Please? The Impstar Deuce don't seem to have any submodules on it, apart from 'shields'. Also, an Impstar I seems to have some kind of super mag-pulse missiles, which can disable another destroyer or almost anything else in one salvo. Other than that, great work! Especially with the multiple torpedoe/missile launching things in again. The Vic one and the torpedoe sphere in 0.45 were my favourite because of the reason.
