These giant cannons can be found on all types of ships, but It is especially indispensable for passenger ships.While it is very obvious on some ships, it may be hidden somewhere on others.

Bride, What is the use of this interesting ball? let’s see.

These big white balls on ships are called radomes.

A radome consists of two parts, a radar and a dome, and is therefore also called a ra-dome. Radomes are basically It contains rotating radar antennas and satellite disks that are in constant motion.

These white balls are designed to move not only from the radar itself but also from the ship. The ship is exposed to the movements caused by the sea and the air. Therefore It is critical that the radome be large enough to allow for this movement.

Radomes are used for many purposes, especially by cruise ships.

Most importantly, for radar equipment provide a weatherproof enclosure. Because they are located on the upper deck of the ship, the equipment must be resistant to adverse weather conditions such as wind, hail, rain and snow.

Also, having the radar equipment inside the radome provides protection for the passengers. Some parts of the radar rotate and Keeping them hidden in the radome reduces the risk of a possible accident.

These white balls can actually be constructed in any way, but Generally, a spherical shape is preferred. The important thing is that they have a sloping top. This slope helps to cope with wind coming from any direction.

Finally, radomes are usually white because a black or dark colored radome, It absorbs heat from the sun and can cause various problems for the equipment inside.
