Aircraft carrier maintenance fortune telling

Why do aircraft carriers spend a lot of time on maintenance?

Because the aircraft carrier is a huge and complicated weapon and equipment, its maintenance is also a very complicated project.

Generally speaking, the maintenance of aircraft carriers is divided into two categories: one is minor repairs, which are mainly aimed at some common components of aircraft carriers. For example: the elevator of the aircraft carrier, the anti-skid layer of the flight deck and the compartment of the hangar. Refurbish or repaint the surface corroded by seawater, and replace the damaged valves and cables to ensure the normal use of the aircraft carrier in the future.

If "minor repairs" are just minor repairs, they are not "bone-breaking" and do not involve high-tech fields (the cost ranges from millions to tens of millions of dollars). Then there is another category that belongs to overhaul.

The overhaul of aircraft carrier generally involves the important components or core technologies of aircraft carrier, such as power system, electronic warfare, weapon launch and communication of aircraft carrier. These tasks sometimes require the carrier to return to the shipyard (the cost ranges from tens of millions of dollars to hundreds of millions of dollars, or even billions of dollars).
