So it was my first ever Yamato battle, didn't install any module or crew skill as I wanna test it out first. So my first spotter plane got shot down, but the range didn't go away. I then launch a second spotter plane. The range somehow stack-up! Clean client no mods or anything. Edit: I just test again after cleaning my Yamato, not working. Maybe it's just the first battle? Edit2: I've no idea Yamato stock range is 26k, apologies from a GFK player, damn Yamato's gun is crazy.
