Naval electronics must withstand salt water as well as the shock and damage of combat. Protection also has to account for electromagnetic pulses, spoofing, and other interference. Some early shipboard computers suffered interference from their own ship's radar, an example of why powerful systems must be designed to operate together. Phased arrays can direct their energy away from the ship, but the electronics still need protection against accidental exposure. Rapid understanding of the tactical picture depends on capable computers, sensors, and an integrated engagement system. All of that requires substantial electrical generation as well as money, personnel, and protected space.

Protecting naval electronics from seawater, shock, and radar
A warship must protect its computers from the maritime environment and its own emissions while supplying the power needed for rapid tactical decisions.
