AEGIS

The Oxford Companion to American Military History | 2000 | | Copyright

AEGIS. The AEGIS Combat System is a sophisticated shipborne target detection and tracking system developed by the U.S. Navy and currently installed in twenty‐eight Ticonderoga‐class guided missile cruisers and eighteen Arleigh Burke–class fleet escorts.

The U.S. Navy developed AEGIS in the 1970s in response to the Soviet threat of saturation missile attacks against American carrier forces. Conventional rotating radars cannot rapidly track and process multiple targets, but AEGIS planar arrays are able to track an unlimited number of targets and relay the data instantaneously to a main computer in the ship's combat information center. The system then rapidly prioritizes the target data received from its SPY‐1 phased array radars and assigns targets to the ship's weapons systems. Superior to more conventional radar systems and highly resistant to electronic countermeasures, AEGIS has also enhanced the target collection and processing capability of Ticonderoga‐class cruisers serving as flagships for battle groups.

Budget limitations prompted the navy, which originally intended AEGIS for nuclear‐powered escorts, to substitute the less expensive, but proven, oil‐fired Spruance‐class design for its new guided missile cruisers In 1988, the first of an AEGIS‐equipped class of fleet escorts, USS Arleigh Burke (DDG 51), was launched, and to date twenty‐eight have been completed.

To support joint and coalition operations against adversaries in littoral areas, the U.S. Navy has offered the AEGIS system to allied navies. Japan already has a significant AEGIS capability and Spain plans to install the lighter, more compact SPY‐1F arrays in its new F‐100 class frigates.
