Delivering unmatched, scalable air and missile defense to the fleet

SPY-6 is the U.S. Navy family of radars that perform air and missile defense on seven classes of ships.

The SPY-6 family is integrated, meaning they can defend against ballistic missiles, cruise missiles, hostile aircraft and surface ships simultaneously. They provide several advantages over legacy radars, including significantly greater detection range, increased sensitivity and more accurate discrimination. 

Each variant uses the same hardware and software, and their construction is modular, making them more reliable and less expensive to maintain.

SPY-6 radars are built from individual ‘building blocks’ called Radar Modular Assemblies, or self-contained radars that come in 2’x2’x2’ boxes. Those boxes stack together to fit the mission requirements of any ship – a feature that makes the SPY-6 family the Navy’s first truly scalable radars.

A closer look at the SPY-6 variants
