you are forgiven schem you looked up a weapon not a system
The name is sometimes spelled AEGIS, supposedly an acronym for phrases such as Advanced Electronic Guidance Information System. However, such attributions seem to be backronyms or fake etymologies. (It is also possible there has been some confusion with the EGIS software used by some AWACS aircraft.) The main manufacturer of the Aegis combat system, Lockheed Martin, makes no mention of it being an acronym.
Combat Information Center (CIC) consoles aboard USS Normandy, 1997.The heart of the system is an advanced, automatic detect-and-track, multi-function three-dimensional passive electronically scanned array radar, the AN/SPY-1. Known as "THE SHIELD OF THE FLEET", the Aegis high-powered (four megawatt) radar is able to perform search, tracking, and missile guidance functions simultaneously with a track capacity of over 100 targets at more than 100 nautical miles.[1] The first Engineering Development Model (EDM-1) was installed in the test ship, USS Norton Sound, in 1973. The Aegis system uses missile uplink using the AN/SPY-1 radar for midcourse guidance of Standard missiles during engagements, but still requires the AN/SPG-62 radar for terminal guidance. This means that with proper scheduling of intercepts, a large number of targets can be engaged simultaneously.
The computer-based command-and-decision element is the core of the Aegis combat system. This interface makes the Aegis combat system capable of simultaneous operation against a multi-mission threat: anti-air, anti-surface and anti-submarine warfare. The Aegis system is being enhanced to act in a Theater Missile Defense role, to counter short- and medium-range ballistic missiles of the variety typically employed by rogue states (see Aegis Ballistic Missile Defense System).

Destroyers have two displays while cruisers have four.The Navy built the first Aegis-equipped cruisers using the hull and machinery designs of Spruance-class destroyers. The first cruiser of this class was the Ticonderoga, which uses two twin-armed Mark-26 missile launchers, fore and aft. The commissioning of the sixth ship of the class, the Bunker Hill opened a new era in surface warfare as the first Aegis ship outfitted with the Martin Marietta Mark-41 Vertical Launching System (VLS), allowing a wider missile selection, more firepower, and survivability. The improved AN/SPY-1B radar went to sea in the Princeton, ushering in another advance in Aegis capabilities. The Chosin introduced the AN/UYK-43/44 computers, which provide increased processing capabilities.
In 1980, a destroyer was designed using an improved sea-keeping hull form, reduced infrared, and radar cross-section and upgrades to the Aegis Combat System. The first ship of the Arleigh Burke class, the USS Arleigh Burke, was commissioned in 1991. Because the Aegis system dominates the ship's architecture, ships equipped with it are sometimes mistakenly called Aegis class ships.
Flight II of the Arleigh Burke class, introduced in 1992, incorporates improvements to the SPY radar, and to the Standard missile, active electronic countermeasures, and communications. Flight IIA, introduced in 2000, added a helicopter hangar with one anti-submarine helicopter and one armed attack helicopter. The Aegis program has also projected reducing the cost of each Flight IIA ship by at least $30 million.
