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-1F radar antenna is a modified version of proven SPY-1D installed aboard Burke-class destroyers, as well as other ships worldwide. The new radar demonstrates SPY-1 adaptability, flexibility and scalability. SPY-1F has been tailored for frigate/corvette-sized ships. SPY-1Fs are planned for installation aboard five Norway's Nansen-class frigates to be commissioned beginning in 2005. The first SPY-1F radar was activated early in 2005 aboard Norway's Fridtjof Nansen frigate.
