RTX’s missile and defence business has received a $511.5m US Navy contract modification to produce hardware and purchase spares for the AN/SPY-6(V) family of radars.
The sole-source award modifies previously granted contract N00024-22-C-5500 and is structured across fixed-price incentive (firm-target), firm-fixed-price and cost-only terms.

Naval Sea Systems Command in Washington, DC, serves as the contracting activity.
The work will be carried out at more than a dozen locations across the US. Andover, Massachusetts, accounts for the largest share at 30%, followed by San Diego, California, and Scottsdale, Arizona, each at 10%. Completion is expected by November 2031.
Funding is drawn predominantly from fiscal 2025 shipbuilding and conversion (Navy) appropriations totalling roughly $499.9m, representing 98% of the obligated amount. The remainder comes from fiscal 2026 operations and maintenance funds of approximately $9.6m and fiscal 2026 other procurement funds of about $2m.
The modification follows a separate $515m contract awarded to Raytheon, part of RTX, in June 2026 to continue supporting the SPY-6 radar programme.
The SPY-6 serves as the primary air and missile defence sensor across seven classes of US Navy vessel. Arrays are currently being installed on DDG 51 Flight III destroyers, frigates, aircraft carriers and amphibious warships, while legacy DDG 51 Flight IIA destroyers and older carriers are being retrofitted with the system.
Central to the radar’s design is a modular architecture built around radar modular assemblies, compact self-contained antenna units that can be combined in varying quantities to suit different platform requirements. RTX describes this approach as making the SPY-6 the Navy’s first truly scalable radar family.
As every variant shares identical hardware and software, the company says the design reduces maintenance costs and improves reliability.
The radars are built to detect and engage a broad spectrum of threats simultaneously, spanning ballistic missiles, cruise missiles, hypersonic weapons, hostile aircraft and surface combatants.
RTX says the system provides weapons such as Standard Missile variants with the precise targeting and threat data needed to maximise their effectiveness.
