It was the heaviest known projectile to be used in a coil gun experiment. A normal torpedo move at 58 mph and have a 24 mile range. The China coilgun torpedo looks like it is 15 inches wide instead of the US coilgun system with 4 inch wide projectiles.

A 120mm-calibre (4 inches wide) electromagnetic coil mortar test device at the Sandia National Laboratories in the United States is one of the closest rivals to the Chinese coil gun. Among the largest of these devices ever built, the device is capable of firing a projectile weighing 18kg.

According to Professor Guan Xiaocun of the Naval University of Engineering, the coil gun has several advantages over traditional artillery, including faster launch speeds and lower launch costs.
