== History ==
The AN/SPY-1 radar is an passive electronically scanned radar system and one of the key components of the [[AEGIS System]]. The SPY-1 was first installed on the test ship USS Norton Sound in 1973 and entered active service in 1983 on CG-47 Ticonderoga.While the first ships with the SPY-1 radar have already been decommissioned, new ships with the latest variants of these radars are still being ordered.

So far, there have been several versions of the SPY-1 radar.
* SPY-1, the prototype installation installed on Norton Sound
* SPY-1A, the first operational type, installed on the first 11 Ticonderoga class cruisers
* SPY-1B, installed on the last 15 Ticonderoga class cruisers
* SPY-1D, installed on the DDG-51 class and all later installations with the full size antenna. 
* SPY-1F, frigate radar installation, has a 2,4 meter diameter as opposed to the 4 meter of the original antenna. Used on the Nansen class. 
* SPY-1K, or corvette variant. The size of the antenna is reduced to just 1,5 meter. None are in service so far.
