Ships that are quite large(i.e. the odyssey, all carriers except for the escort ones, bortas/'qu,etc.), should have either 5 forward and 4 aftward weapon slots or 5 forward and 5 aftward ones(considering the size of these ships). I think that all non-escort carriers and the flagships for Starfleet and the KDF and the new Romulan dreads should have 5 and 5 weapon slots, while the Dominion escort carrier would have 5 forward and 4 aftward weapon slots.
