On May 19, 2025, Raytheon RTX officially delivered the first Gallium Nitride (GaN)-equipped AN/TPY-2 radar to the U.S. Missile Defense Agency (MDA), as reported by RTX. This cutting-edge radar system, categorized under advanced ground-based air and missile defense sensors, represents a central technological pillar in President Donald Trump’s proposed “Golden Dome” national missile shield, a concept for a layered homeland defense integrating multiple interceptor systems across the U.S.Follow Army Recognition on Google News at this link

Against the backdrop of growing threats from ballistic and hypersonic missile technologies developed by China, Russia, and other strategic competitors, the deployment of the GaN-upgraded AN/TPY-2 radar is a major leap forward in missile detection and early warning capabilities. Designed to operate in the X-band of the electromagnetic spectrum, the radar provides significantly higher resolution than previous systems. Its mission: detect, track, and discriminate among complex missile threats across multiple phases of flight. The system can function independently of THAAD batteries, enhancing flexibility and strategic placement for U.S. homeland defense. The relevance of this deployment is underscored by the urgent need to modernize America’s missile defense network in the face of evolving hypersonic threats. With the inclusion of high-performance CX6 computing software, this radar marks a turning point in how the U.S. handles early detection and discrimination, critical for initiating timely interception and avoiding wasted missile launches on decoys.
The AN/TPY-2, measuring over nine meters in height and weighing approximately 30 tons, is a mobile, truck-transportable radar originally designed to guide THAAD interceptors. However, with the GaN array, its operational scope has expanded to include support for Patriot and SM-series missiles. GaN semiconductors offer higher power output, better efficiency, and greater thermal stability than the older Gallium Arsenide (GaAs) components. These attributes translate into double the detection range and a much earlier command-and-control window for operators to select the appropriate missile defense effector. The radar’s precise discrimination capabilities are crucial against modern threats, such as hypersonic glide vehicles, which maneuver unpredictably and produce minimal radar signatures compared to traditional ballistic warheads. Its integration into both forward-deployed and homeland-based defense networks makes it a key enabler in the Pentagon’s push for comprehensive 360-degree missile defense coverage.
Operationally, the AN/TPY-2 has already seen extensive deployment in U.S. and allied missile defense architecture. Early versions are active in Japan, South Korea, and the Middle East, where they provide vital coverage against regional missile threats. The development of the GaN variant was pioneered by Saudi Arabia, which received the first upgraded unit in 2024. Raytheon initiated the GaN modernization under a 2016 MDA contract, collaborating with allied nations to share both development costs and technological returns. This collaborative model not only reduced the financial burden on the U.S. but also ensured interoperability with allied systems, a key component of the Golden Dome’s multinational architecture. The upgraded AN/TPY-2 is now the 13th such radar delivered to the MDA, but the first with the new technology, highlighting a new operational chapter in the radar’s lifecycle.
Compared to its predecessors and peer systems such as the Israeli EL/M-2080 Green Pine or the French Ground Master 400, the upgraded AN/TPY-2 offers superior detection at longer ranges and greater resilience against electronic attack. Unlike these systems, which are often fixed-site installations or optimized for shorter-range threats, the AN/TPY-2 combines mobility, scale, and deep integration with layered U.S. missile defense networks. Its role in hypersonic missile detection, in particular, places it in a different category of operational relevance, one tailored for future threats rather than legacy ballistic missile defense.
Strategically, the deployment of the upgraded radar fits squarely into the framework of Trump’s Golden Dome initiative. Designed to create a national missile shield analogous to Israel’s Iron Dome, but scaled for continental defense, the Golden Dome depends on layered detection and engagement: from long-range radars like the AN/TPY-2 to interceptors like THAAD, Patriot, and the SM-3 and SM-6. This radar’s ability to interface across all those systems ensures that the first link in the kill chain, detection, is both reliable and timely. Its integration allows military decision-makers to “shoot earlier” and with greater precision, especially against emerging threats like maneuverable hypersonic glide vehicles.
From a budgetary standpoint, the AN/TPY-2 program has seen increasing investment. The MDA’s FY2025 budget includes more than $8 million for operational sustainment of the 13th radar and an additional $29 million to accelerate the acquisition of GaN-based components. These figures highlight the radar’s strategic priority amid tightening defense budgets and shifting Pentagon focus toward great-power competition. Although Raytheon holds the principal production and upgrade contract, the internationalization of the program, with early adoption by Saudi Arabia and future potential partners like the UAE (which recently signed a memorandum with RTX to develop regional GaN production capacity), adds a broader geopolitical dimension to the system’s deployment.
The delivery of the GaN-upgraded AN/TPY-2 radar from Raytheon to the U.S. Missile Defense Agency is more than a technical milestone, it is a strategic statement. As a cornerstone of the envisioned Golden Dome missile defense shield, this radar system addresses the pressing need for early, accurate, and reliable detection in an age of hypersonic threats. Its enhanced range, mobility, and precision mark a transformative leap in radar capability, one that reinforces U.S. homeland defense and enables a more integrated missile defense strategy with key allies. As adversaries push the limits of speed and maneuverability in missile technology, systems like the AN/TPY-2 ensure that the U.S. remains not just reactive, but prepared.
