Military computer installations need protection against dust, shock, heat, cold, water, and electromagnetic pulse. Their space requirement includes cooling, networking cables, sensors, and the equipment connecting those systems. The comparison with a gun installation includes ammunition hoists, spotting, and fire-control equipment when counting the space occupied by weapons. A further example uses electrical service equipment at roughly 500 kilowatts to show how power distribution and generator windings consume substantial volume. Maintenance access adds to the room that designers must reserve.

The equipment surrounding a warship's computers
Environmental protection, cooling, cables, sensors, and electrical equipment make a combat computer installation much larger than its processor cabinets.
