What drives the cost to retrofit a fleet

endless-spaceendless-space-disharmony

I was wondering if it would not be more practical to build hollow ships with nothing on board, and to retrofit them to match an ennemy's weaknes when time comes.

Would it be more expensive to retrofit ships that were built with nothing in them (i.e. with a much lower industry cost) ? Is it more expensive to retrofit several steps at a time ? How is the cost calculated ?

What I have in mind is to find a cheaper solution than stacking dust and buying everything when you are attacked.

Refitting/upgrading ships appears to be done at a fixed cost based on the hull size - this is regardless of how much is being changed.

There appears to be no discount when refitting multiple ships.

It's rather expensive and so it would probably make your plan not feasible.
