The ships are fairly obviously kit-bashed from a set of central sections, engine mounts and peripheral equipment/weapons. I highly doubt much or any of the 2gigs of data was devoted to them tbqh. It is more likely that the vast majority of ship components are already in game.. they may have added a new variation or 2 on certain parts to the pool but we're talking small potatoes in terms of file size.

Malovi, you are talking graphical assets. It doesn't cost them extra space to store that. But when they put the assets together they create a FILE. Each ship is an individual FILE that takes space, 3d models take a decent amount of space. As far as the 2gigs you're talking about dark below. The 30 ships are in house of wolves. Get your expansion talk straight before you bring on an argument

There were new ships in TDB and you did not specify what you were referencing. Again, the amount of file size (and art team time) devoted to ships is likely minimal based on the kit-bash workflow they appear to use to create them.
