Upgrading Battle Stations

Commercial battle stations generally don't have upgrade slots. Although the bulwark, explorer, and skirmisher frames all provide one of their default battle stations with an upgrade, that upgrade can't be removed, and it doesn't count toward the upgrade limit of the battle station. Battle stations have a single upgrade slot when they become tactical, two when they become advanced, three when they become elite, and four when they become paragon. As your crew and starship level up, you can freely experiment with different upgrades to suit your playstyle or even to prepare for a specific threat you know you're about to face during your next outing.

Your battle station upgrades also improve with your starship's level. Many upgrades have higher-level versions as well and can be installed freely while at port once your starship reaches the prerequisite level. The weapon installed in your gunnery has a grade equal to your gunnery's, allowing you to also install weapon upgrades into your starship weapon for free.
