While the color tones may vary slightly, most warships in the world are painted gray, instead of blue?

At a sufficient distance, the gray paint will make the warship more difficult to detect, especially when it is close to the horizon, the gray paint will make the warship nearly invisible from the human eye.

In foggy weather, the gray paintwork will also make warships more concealed, avoiding detection from long distances.

Another feature, the gray paint color, makes it difficult to determine the height of the warship with the naked eye, since it closely resembles the color of the sky when viewed from a distance. Therefore, it will be extremely difficult to determine the distance to a warship with conventional observation equipment, and it will be impossible to fire accurately.

Not only the color of the ship’s hull, the paint color of the deck, is also influenced by many factors. Specifically, the floor surface of American warships is often gray. Meanwhile, Russian warships often have red painted floors. Basically, the paint on the deck must ensure the durability due to continuous sunlight for many months. It also needs to be cheap, as it will have to be repainted repeatedly. The red paint on the Russian deck, also plays a role in anti-corrosion, helping to increase the durability of the ship when operating continuously in inclement weather.

Because there are so many warships painted in gray, the nationality of these warships in international waters is often based on communication systems, or their designs. Historically, there have been catastrophic mistakes when submarine sailors misidentified the design, type and nationality of a surface ship, leading to the disaster of mistaking the warship.

With today’s advanced technology, distinguishing warships of nations has been much simpler. At the present time, large warships can be detected on the radar very early, instead of trying to search for each other on the horizon as in the past.
