The bay will have grand total of three floors and the construction will be the largest version yet.
This bay will look something like precursor array’s underwater entrance, which is massive enough to fit the Cyclops. Much like moon pool base piece, the enclosed docking bay will recharge the Cyclops and the Vehicle it carries while docked.
Once docked and clamped into place, the doors will automatically close and the water will begin to drain, thus will be allowed to exit. It should have mechanical arms that clamps onto the ship, guide it into position where you will proceed to step away from the controls. Much like real life docking bays, we need one that allows for the submarine to be docked below or above water.
