Raytheon Completes SPY-6(V)4 Installation at Wallops; Testing Extends Through Mid-2028 Ahead of USS Pinckney Backfit
Raytheon's statement that Wallops testing 'reduces the amount of testing needed on DDG 91' and 'means less time in the shipyard' is the critical constraint: the company is frontloading integration risk to compress shipyard duration. If that bet fails—if power system or combat system interface issues emerge at Wallops that require rework before shipboard installation—the schedule compresses further, not relaxes. The Navy has already compressed DDG 91's availability window to 18-24 months during a period when surface combatants are being surged to the Indo-Pacific and Middle East; a slip on Wallops testing becomes a slip on fleet modernization at the moment when the surface fleet is most strained.
USS Pinckney's backfit window—late 2026 to 2028—overlaps the Hormuz escalation cycle already underway.
If testing at Wallops slips beyond mid-2028, DDG 91 enters the fleet without SPY-6(V)4 during the period when surface combatants face the densest air and anti-ship threat environment in a decade: PLA Type 052D destroyers now carry YJ-20 hypersonic missiles (600-900nm range), and the Red Sea/Hormuz theater is actively contested. Raytheon's $800M capacity investment targets doubling SPY-6 output by 2028, which means the company is betting the production ramp holds even if supply-chain or manufacturing delays emerge—a constraint that will surface in Q4 2026 when DDG 91 enters the shipyard. Watch whether the Navy requests acceleration of Lot 16 procurement in the FY27 supplemental; if Wallops testing reveals integration issues that push mid-2028 closer to late-2028, the backfit schedule breaks and the first-ship penalty lands on a hull that should already be modernized.
What is the actual test timeline at Wallops—is the mid-2028 completion date tied to DDG 91's availability window, or is there schedule slack if integration testing identifies design issues?
