USS Pinckney Becomes First U.S. Navy Destroyer to Begin SPY-6(V)4 Radar Backfit to Boost Air and Missile Defense
USS Pinckney (DDG 91) has begun its second depot modernization period at General Dynamics NASSCO in San Diego, becoming the first in-service U.S. Navy destroyer scheduled to receive the AN/SPY-6(V)4 radar. The DDG MOD 2.0 upgrade combines Raytheon’s four-face active electronically scanned array with Aegis Baseline 10 and new High Efficiency Super-Capacity cooling plants to support greater sensor and combat-system demands. Pinckney previously received SEWIP Block 3 electronic warfare equipment during an earlier yard period in 2024. NASSCO’s September 2026 modernization contract is worth approximately $149.6 million, with completion scheduled for September 2028.
