Aegis
Aegis is an advanced naval weapons system that uses powerful computers and radar to track and destroy multiple airborne and sea-based threats simultaneously. It acts as a protective shield for a warship or an entire fleet against attacks from aircraft, drones, and missiles.

TECHNICAL DEFINITION
The Aegis Combat System (ACS) is an integrated naval weapon system (IWS) developed by the US Navy, centered on the AN/SPY-1 phased-array radar and a centralized command and control (C2) suite. It provides comprehensive anti-air warfare (AAW) and ballistic missile defense (BMD) capabilities for surface combatants, such as Ticonderoga-class cruisers and Arleigh Burke-class destroyers, by performing search, track, and missile guidance functions simultaneously.
BACKGROUND
The Aegis ballistic missile defense system, also known as Sea-Based Midcourse, is a Missile Defense Agency program under the United States Department of Defense developed to provide missile defense against short and intermediate-range ballistic missiles. The program is part of the United States national missile defense strategy and European NATO missile defense system.
