Overview

• The AN/SPY-6(V)4 underwent multiple trials at the Advanced Radar Detection Laboratory at the Pacific Missile Range Facility in Hawaii.
• The radar tracked air and surface targets under varied conditions, generating the first live data set for this configuration and confirming performance predicted by simulations.
• The (V)4 variant is slated for Arleigh Burke-class Flight IIA destroyers under DDG MOD 2.0, replacing legacy SPY-1 systems with a 24–Radar Modular Assembly array.
• Program officials say testing and system enhancements will continue, leveraging common SPY-6 hardware and software to ease integration across ship classes.
• Breaking Defense notes a $3.2 billion 2022 award covering production and sustainment for delivery to 31 ships over five years, with wider deployment projected to more than 60 ships over the next decade; Naval News reports USS Pinckney is expected to be the first Flight IIA upgrade starting in 2026.
