First of Its Kind with Advanced GaN Technology
Raytheon has successfully delivered the first upgraded AN/TPY-2 radar, capable of tracking hypersonic missiles, to the Missile Defense Agency (MDA). This enhanced radar, featuring cutting-edge Gallium Nitride (GaN) technology, offers increased range and improved targeting precision, marking a significant advancement in missile defense capabilities.
Enhanced Range and Versatility
According to Raytheon Vice President Jon Norman, the upgraded radar now “sees twice as far,” enabling earlier decision-making for missile interceptors like THAAD, Patriot, or SM series systems. Unlike earlier versions, the new AN/TPY-2 can be deployed as a mobile, standalone unit, not necessarily wired into a specific missile battery, supporting broader missile defense initiatives, including President Trump’s Golden Dome plan for an integrated homeland shield.
Technical Innovations: GaN and Software Upgrades
The key upgrade involves replacing the previous Gallium Arsenide (GaAs) semiconductors with GaN modules, praised for their energy efficiency, lighter weight, and higher power output. The new radar also incorporates CX6 high-performance software, which enhances target discrimination and electronic attack resilience.
Superior Tracking of Hypersonic Missiles
Hypersonic missiles, capable of maneuvering mid-flight, present increased detection challenges compared to ballistic missiles. Norman explained that this upgraded radar can identify small, maneuverable targets at the booster separation phase, enabling earlier, more accurate interception. Its improved discrimination allows operators to distinguish genuine warheads from clutter and debris, minimizing wasted interceptors.
Global Collaboration and Production
This delivery marks the 13th AN/TPY-2 system, with the first GaN-equipped unit delivered to Saudi Arabia last September. Norman highlighted that the upgrade was a collaborative effort, funded not only by the US but also through contributions from international partners—including Japan, South Korea, and others—sharing the development costs to enhance capabilities worldwide.
Funding and Future Plans
The MDA’s fiscal 2025 budget request allocates over $8 million to maintain and operate the latest radar, with nearly $29 million dedicated to procuring GaN modules to modernize the entire AN/TPY-2 fleet. This modernization seeks to replace aging Gallium Arsenide components, upgrade system performance, and expand hypersonic tracking capabilities, crucial for countering emerging threats.
Outlook
The deployment of the new GaN-based AN/TPY-2 marks a pivotal step in modern missile defense. With increased range, precision, and international cooperation, this upgraded radar enhances the US and allied defenses against ballistic and hypersonic missile threats, ensuring a more resilient and adaptive missile defense architecture moving forward.
