U.S. Navy’s SPY-6 Family of Radars

Delivering Unmatched, Scalable Air and Missile Defense to the Fleet

Body

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 are 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.

    SPY-6(V)1 simultaneously defends against:

    • Ballistic missiles
    • Cruise missiles
    • Anti-surface and anti-air threats
    • Jamming/clutter and electronic warfare

    SPY-6(V)2 – also known as the Enterprise Air Surveillance Radar (rotator variant)

    Designed for amphibious assault ships and Nimitz-class carriers, SPY-6(V)2 features:

    • 1 rotating array face – with 9 RMAs – providing continuous, 360-degree situational awareness
    • Air traffic control and ship self-defense capabilities

    SPY-6(V)2 simultaneously defends against:

    • Cruise missiles
    • Anti-surface and anti-ship threats
    • Jamming/clutter and electronic warfare

    SPY-6(V)3 – also known as the Enterprise Air Surveillance Radar (fixed-face variant) 

    Designed for Ford-class aircraft carriers and FFG(X) guided missile frigates, SPY-6(V)3 features:

    • 3 fixed-face array faces – each with 9 RMAs – providing continuous, 360-degree situational awareness
    • Air traffic control and ship self-defense capabilities

    SPY-6(V)3 simultaneously defends against:

    • Cruise missiles
    • Anti-surface and anti-ship threats
    • Jamming/clutter and electronic warfare

    SPY-6(V)4

    Designed for DDG 51 Flight IIA destroyers, SPY-6(V)4 features:

    • 4 array faces – each with 24 RMAs – providing continuous, 360-degree situational awareness
    • Significantly enhanced range and sensitivity compared to the radar it replaces

    SPY-6(V)4 simultaneously defends against:

    • Ballistic missiles
    • Cruise missiles
    • Anti-surface and anti-air threats
    • Jamming/clutter and electronic warfare
