As of patch 1.14 (November 2021) this refit is no longer possible. I will get a new one on the channel asap!

I have been talking about upgrading the Sevastopol from the 'hanger queen' default fit-out for a long time in my campaign. In this video I go over some simple changes to the Sevastopol and then continue onward until the refit I am going to use in my playthrough for the endgame.
