A turret assembly without deck penetration for minimizing exposure of combatants to enemy forces when accessing above deck equipment comprises a base plate on top of which is mounted at least one finable and remotely operable combatant interfaceable implement, the base plate being rotatable about a substantially vertical axis and supported for rotation by bearing means mounted within a deck of a military facility; a hatch displaceably connected to the base plate, for normally covering a hatchway formed in said base plate and for exposing said hatchway when displaced; and a rotatable disc of a slip ring unit carried by the hatch, by which electricity for operating equipment mounted on top of the deck and for initiating control signals is transmitted to the equipment.
