The SPY-6 family is integrated, meaning it can defend against ballistic missiles, cruise missiles, hostile aircraft and surface ships simultaneously. And it offers 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

The radar optimizes the effectiveness of the Navy’s most advanced weapons, including all SM-3 interceptor and SM-6 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 SPY-6 more reliable and less expensive to maintain.

It’s 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 SPY-6 the Navy’s first truly scalable radar.

SPY-6 arrays are being delivered and integrated onto the Navy’s newest ships, including its first Flight III guided missile destroyer, the future USS Jack H. Lucas (DDG 125), and the future USS John F. Kennedy (CVN-79).

A closer look at the SPY-6 variants

  • SPY-6(V)2
  • SPY-6(V)3
  • SPY-6(V)4

Designed for the DDG 51 Flight III destroyers, SPY-6(V)1 features:

  • 4 array faces – each with 37 RMAs – providing continuous, 360-degree situational awareness
  • Significantly enhanced range and sensitivity compared to the radar it replaces

SPY-6(V)1 simultaneously defends against:

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