Description: The AN/SPY-1 radar system is the primary air and surface radar for the AEGIS weapon system. It is a multifunction phased-array radar capable of search, automatic detection, transition to track, tracking of air and surface targets, and missile engagement support. Typically each AEGIS-equipped ship has 4 SPY-1 radar antennas continuously covering 360-degree and providing a search and tracking capability for hundreds of targets at the same time.

The SPY-1 also provides fire control capability, rapid transition from silent to full radiate mode, fast reaction semi-automatic system in less than10 seconds, high rate of fire (less than 2 seconds per launcher), illumination required only for a short period of time prior intercept, and other minor capabilities. The SPY-1 radar system also has some weakness such as false targets from land clutter, re-engage no possible, antenna height lower than other radar systems resulting in reduced radar horizon, and target engagements must be carried out by the SPY-1 radar unless equipped with Cooperative Engagement Capability (CEC).

The SPY-1 radar system was developed in the 1970s. The SPY-1D radar antenna is a derivative of proven SPY-1B installed aboard latest Ticonderoga cruisers. SPY-1D has been tailored for destroyer-sized ship. SPY-1Ds are installed aboard DDG 51-class destroyers, Kongo-class Japanese destroyers, F100-class Spanish frigates, and Korean KDX-class destroyers.

The upgraded SPY-1D(V) is being installed on DDG 51 Flight IIA ships and has been optimized against low-altitude, reduced radar cross section targets in heavy clutter and electronic countermeasures environments. It will be available in 2003 and is also known as the Littoral Warfare Radar.

On 12 July 2006, Raytheon made public that was awarded a $73 million contract for the advanced procurement of AN/SPY-1D(V) radar antennas for the first three Australian Air Warfare Destroyers (AWDs). The contract also included system transmitters, associated hardware and spares.
