RTX’s Raytheon completes installation of first SPY‑6(V)4 array at Wallops Island test siteRaytheon has installed the first land-based SPY-6(V)4 radar array at Wallops Island, Virginia, commencing land-based testing ahead of the backfit deployment on USS Pinckney (DDG 91). Raytheon press releaseRaytheon, an RTX business, has delivered and installed the first SPY-6(V)4 radar array at Surface Combat Systems Center at Wallops Island in Virginia, marking a major milestone for the U.S. Navy’s Flight IIA Destroyer modernization effort and the SPY-6 backfit program. DDG 91 is scheduled to be available for the SPY-6(V)4 backfit from late 2026 to 2028. The Navy and Raytheon are using the Wallops site to meet this tight schedule and ensure a smooth transition from maritime environment testing to shipboard installation and operation. With these upgrades, Raytheon is positioned to double SPY-6 output by 2028, helping ensure long-term availability and lowering cost for the Navy.
