Classify the ship that is fitted

Should ship classification count equipment a vessel is designed for but does not carry?

No; count what is fitted, not what the ship is merely prepared to receive later.

Classification should describe the capability installed on the ship now. Space, wiring, or structural provision for a future weapon does not make that system operational. A vessel that is fitted for but not with equipment has useful growth potential, but it cannot employ the absent equipment on deployment. Counting paper options would turn classification into a catalogue of possibilities rather than a description of the fleet in service.
