Shipboard electronics must survive conditions that ordinary computer hardware never faces. Graphics, memory, networking, and processing equipment need shock resistance and may require protection from electromagnetic pulse effects. Closely coupled processors also need tight consistency because small differences can introduce errors into a shared radar picture. Those demands make modern combat systems far more expensive than consumer electronics with superficially similar functions.

Why shipboard electronics cost more than consumer hardware
Shock, electromagnetic protection, and tightly matched processing requirements make shipboard electronics far costlier than superficially similar consumer hardware.
