Considering that the US Navy has recently slowed down related green laser pointer research activities, China’s actions are particularly noticeable. Railguns do not use gunpowder, but use electromagnetic energy to fire shells, which means that the speed of the shell may be faster and the range may be longer-equivalent to a shell with a missile effect.
In essence, a rail gun is an electromagnetic-powered artillery. By applying a parallel magnetic field (or “orbit”) to the shell, a hypersonic shell is fired. It is reported that although this technology has attracted the attention of the US military, China is the country that has obtained the most non-public and peer-reviewed research results in this field.
This popular science indicates that China may put many military electromagnetic technologies into use in the future. In addition, at a report conference of Wuhan Naval University of Engineering, China has made breakthroughs in important Green Laser Pointer fields for electromagnetic applications, such as rail guns and electromagnetic catapults. It is pointed out that some of these technological breakthroughs are crucial to the construction of military railguns.
