Will these modules fit in other ships of relative size in the future?

Potentially! We imagine using them in a larger, interconnected system in the future. These will likely follow logical rules in the game universe: Aegis might build other ships to use the same modules, while Anvil ships would have their own process. Imagine, for instance, a future medium bomber similar to the Retaliator that might let you choose only one of these modules instead of two!
