Considering the first 3 missions make a Big Deal about ships, I think you shouldn't even be breaking them down. They should be in a separate list (not inventory driven) and entirely managed by the mechanic who makes a fuss about "keeping your ships in the sky". She should offer every single ship style option for sale using a variety of normal to rare to legendary to exotic materials as currency for each tier of ship design. I think it sucks that the ship design is purely cosmetic even though the cosmetic part seems to show different engines, flight profile and weapon choices built into the ship. When are we going to use these weapons strapped to the ship?
