The rail gun system can make all chinese missiles completely obsolete.

Rail Gun or Lasers - which is better?
One thingy for sure, Rail Gun need heavy lifting power, Laser needs powerful fuel cells!

hmmmm

Problems with railguns

In theory, rail guns are the perfect solution for short- and long-range firepower. In reality, they present several serious problems:

Power supply: Generating the power necessary to accelerate rail gun projectiles is a real challenge. Capacitors must store electric charge until a sufficiently large current can be accumulated. While capacitors can be small for some applications, the capacitors found in rail guns are many cubic meters in size.

Resistive heating: When an electric current passes through a conductor, it meets resistence in the conductive material -- in this case, the rails. The current excites the rail's molecules, causing them to heat. In rail guns, this effect results in intense heat.

Melting: The high velocity of the armature and the heat caused by resistive heating damages the surface of the rails.

Repulsion: The current in each rail of a rail gun runs in opposite directions. This creates a repulsive force, proportional to the current, that attempts to push the rails apart. Because the currents in a rail gun are so large, the repulsion between the two rails is significant.

Wear and tear on rail guns is a serious problem. Many break after a few uses, and sometimes they can only be used once.

Replicating a COMET strikes, this "Rail gun" weapon......
But it needs HUGE PAYLOAD capability in order to weaponized....

How about atmospheric burnt out upon re entry into the atmosphere?

cheerios!
