China Develops Global Missile Defense System

China has created a prototype defense system that can watch for missiles worldwide.

It is like a shield, able to spot missiles from anywhere.

This system, the 'big data platform,' uses sensors to track a thousand missiles at once.

The U.S. has a similar plan called the 'Golden Dome.'

The U.S. project includes interceptors in space, on land, and at sea, with some on the mainland, Hawaii, and Alaska.

The Chinese system gathers data to figure out what each missile is, while the U.S. plan is expected to be very costly.

Both systems are designed to defend against missile attacks.
