Photo Of The Day – A close-in weapon system, or CIWS for short, is a point-defense weapon system for detecting and destroying incoming missiles and enemy aircraft which may have penetrated the outer defenses. It looks a bit like R2D2 in Star Wars when it has its full suite of panels on. It works well on drones.
Most of the time we see them on ships, but we get a closer look today as the Fire Control Technician is working on the system. Below you can see him as he verifies that the barrels are locked.
