SPY-6 radars are integrated, meaning they can defend against ballistic missiles, cruise missiles, hypersonic missiles, hostile aircraft and surface ships simultaneously. They offer many advantages over legacy radars, such as greater detection range, increased sensitivity and more accurate discrimination.

Delivering unmatched, scalable air and missile defense to the fleet

SPY-6 radars optimize the effectiveness of the Navy’s most advanced weapons, including all Standard Missile variants.

Precise targeting information and data on incoming threats allows weapons to maximize their performance.

Each variant uses the same hardware and software, and their construction is modular, making the SPY-6 family more reliable and less expensive to maintain.

Each radar is built with individual “building blocks” called radar modular assemblies. Each RMA is a self-contained radar antenna in a 2’x2’x2’ box. The RMAs 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.

SPY-6 radar arrays are being delivered and integrated onto all the Navy’s newest ships, including DDG 51 Flight III destroyers, frigates, aircraft carriers and amphibious warships, and are being backfit onto legacy DDG 51 Flight IIA destroyers and legacy aircraft carriers.
