The AN/SPY-l radar system is the primary search and track radar for AEGIS-equipped ships. It is a multifunction, phased array radar, capable of three-dimensional surveillance, while simultaneously providing fire control tracking for hundreds of air and surface targets in clear and ECM environments. In addition to search and track, it provides midcourse guidance to the Standard missile (SM-2).

Command and Decision System

The command and decision (C&D) system is a manned computer and display complex that coordinates and controls the AEGIS mission. C&D operators manage automatic CIC operations related to the following:

l Air, surface, and subsurface engagements

l Electronic warfare system control

l Data link control

l IFF challenges

l User defined information alerts

l Weapon tight zones

Weapons Control System

The weapons control system (WCS) schedules, controls, and assesses all air, surface, and subsurface engagements. It is the interface between the C&D and the FCS of the delivery system.

Fire Control System

The fire control system (FCS) provides illumination control for Standard missile engagements. WCS assignment orders and AN/SPY-1 target data make a designation source for the FCS illuminators. The FCS consists of four AN/SPG-62A radar sets. These four sets permit the illumination of multiple targets simultaneously.

AEGIS Display System

The AEGIS display system (ADS) is a computer-controlled display complex that provides various pictures and information of the tactical environment. With the ADS, commanders can observe and control a graphic representation of selected tracks, coastal maps, weapons release zones, and specific warfare environments. After entry of selected information, the displays are automatically updated in regard to own-ship's position. The ADS receives all track information from the C&D system.

Operational Readiness Test System

The operational readiness test system (ORTS) is a computer-controlled test and monitor system that performs automatic fault detection, fault isolation, status monitoring, and system reconfiguration. When a fault occurs, the ORTS automatically assesses and displays the highest level of system impact. Through a keyboard, the operator can initiate tests, evaluate system performance, and load programs into the various AEGIS computers. When tests are being conducted the system uses embedded test equipment throughout the system to measure voltages, analyze data, and measure power and phase.

AEGIS Combat Training System

The AEGIS combat training system (ACTS) enables shipboard personnel to conduct highly integrated multifaceted warfare training scenarios. It also provides the capability to record and print out specific training events for self-evaluation.

All these elements form the core of the AEGIS combat system (ACS). The ACS also integrates and controls the following elements:

l Harpoon weapons system

l Gun weapon system

l LAMPS helicopter

l Electronic warfare system

l sonar

l Air and surface search radars

l Navigation system

The complete integration of all these systems serves to enhance the capability of a ship to engage and defeat numerous multiwarfare threats simultaneously.
