What is the meaning of ASAT (Anti-satellite Weapons)?

This system is mostly used by the countries like United States, Russia, China, and India, especially during the war. This system is specifically designed for destroying satellites. But its role is not restricted to this extend but also it also works towards taking defensive measures against an adversary's space-based and nuclear weapons, a force multiplier for a nuclear first strike, a countermeasure against an adversary's anti-ballistic missile defense (ABM), an asymmetric counter to a technologically superior adversary, and a counter-value weapon.

History:

The original work in progress started from the early 1950s followed by launching multiple on-ground missiles to space for the ultimate testing. The thought was first proceeded by the United States during times of turmoil and war.

The first missile to be sent in the space was named U.S. ASM-135ASAT missile. That marked the starting of such projects luring other war-afflicted countries to follow up to this practice. Now with the advancement of technology, the system is updated to match with the newfound potential to meet today’s needs.

Functioning:

The general use of high altitude nuclear explosions coherent to destroy the target acquired leaving behind no trace of evidence.
