At the NATO summit held in Ankara, Turkey, alongside Ukrainian President Volodymyr Zelenskyy on Wednesday, former U.S. President Donald Trump made a landmark announcement: the United States would grant Ukraine a manufacturing license to produce American-designed Patriot air defense systems, the critical defensive capability Kyiv has pursued for years to shield its population, cities and critical infrastructure from relentless Russian missile and drone attacks.
“We’ll give them the right to make Patriots. We’ll show them how to do it,” Trump told attendees, adding that he believed domestic production could be stood up relatively quickly. But the announcement left a critical detail unresolved: exactly what components or full systems Ukraine would be permitted to manufacture under the license. Zelenskyy framed the announcement as a symbolic and strategic win Thursday, telling reporters that Washington now recognizes Ukraine’s capacity to take on this manufacturing work, and that Ukrainian and U.S. diplomatic and defense teams will begin immediate work to finalize all licensing terms and arrangements.
Patriot air defense systems, and their interceptor missiles specifically, are currently manufactured by major U.S. defense contractors Lockheed Martin and Raytheon, a subsidiary of RTX. Defense analysts and Ukrainian officials emphasize that a general production license does not automatically grant Ukraine the right to build an entire Patriot battery from scratch, which includes launch systems, advanced radar arrays, command and control centers, and interceptor missiles. Instead, the license could be limited to narrower production scopes, such as manufacturing interceptor missiles alone, conducting final assembly from imported component kits, or producing only non-sensitive individual components.
Serhii Beskrestnov, an advisor to Ukraine’s minister of defense, explained that standard U.S. defense manufacturing licenses typically include access to full technical documentation, specialist training, connections to approved parts suppliers, and on-site support from foreign consultants to help launch domestic production. Even so, many experts warn that the first phase of any production will be far more limited than full domestic manufacturing of complete systems.
Anatolii Khrapchynskyi, development director of Ukraine-based defense firm Fly Group Ukraine, notes that Trump’s original announcement was intentionally ambiguous, referencing broad production of “Patriots” without clarifying whether the license covers missiles, launchers, radar, command centers or individual components. Even manufacturing Patriot interceptors alone requires an extensive, interconnected global supply chain, with hundreds of separate suppliers producing specialized parts ranging from control surfaces and rocket engines to precision guidance systems and military-grade communications electronics.
While the Trump administration has not released official details about the scope of the proposed license, an anonymous senior administration official confirmed that the U.S. is already drastically accelerating and expanding its own domestic Patriot production to meet surging global demand, and is forging new industrial partnerships with allied nations around the world to boost output of the systems. The war in Ukraine has already demonstrated how rapidly domestic weapons production can scale when a country gains access to design documentation, technical support, and a steady flow of core components: Ukraine has already become a global leader in low-cost, mass-produced expendable attack drones, while Russia has scaled up its own domestic production of Iranian-designed Shahed-type attack drones (rebranded as Gerans in Russia) at a dedicated facility in Tatarstan. But experts stress that Patriot systems are orders of magnitude more complex than these unmanned vehicles, requiring cutting-edge precision guidance, advanced radar technology, high-performance solid-fuel rocket motors, military-grade microelectronics, and rigorous quality certification standards that Ukraine’s existing defense industrial base cannot yet meet.
Yehor Chernev, deputy chairman of Ukraine’s parliamentary committee on national security, defense and intelligence, projects that while the bureaucratic and legal process for finalizing the license could begin within a few months, actually launching full production will take multiple years. Even if Ukraine receives fully assembled component kits from foreign suppliers, Chernev estimates it would take at least 18 to 24 months to launch the first pilot production line, with additional time required to roll out the first completed finished weapons. The PAC-3 MSE interceptor, the most modern variant designed to shoot down incoming ballistic missiles, takes roughly 24 months to produce in the U.S. alone, with the solid-fuel rocket motor alone requiring around 30 months of manufacturing work. Chernev added that the most sensitive technologies, particularly the interceptor’s active radar seeker, are unlikely to have their full design documentation transferred to Ukraine for domestic manufacturing, meaning Ukraine will almost certainly have to import the most complex high-tech components and focus initial efforts on final assembly, systems integration, or production of less sensitive parts.
Dr. Thomas Withington, an electronic warfare, radar and military communications analyst at the London-based Royal United Services Institute, emphasized that public expectations for quick results need to be tempered. While Ukraine’s existing defense industrial base can support early steps toward production, the country still requires significant time to construct specialized manufacturing facilities, train a skilled domestic workforce, and secure stable, uninterrupted supply chains for all required components. “This is not going to be a fix for the air-defense threats Ukraine is going to face tomorrow,” Withington noted.
The U.S. has a history of allowing allied nations to produce Patriot components under license, and these past examples illustrate that while licensed production is achievable, it proceeds far slower than many observers hope. Japan has produced Patriot missiles under U.S. license for decades: Mitsubishi Heavy Industries has assembled PAC-3 interceptors under an agreement with Lockheed Martin, and Japan relaxed its post-World War II arms export restrictions several years ago to allow for the export of U.S.-designed Patriot missiles back to the U.S., a shift that could indirectly help replenish American stocks drawn down by support to Ukraine. A more recent example comes from Germany, where Raytheon and MBDA Deutschland announced a licensed Patriot GEM-T missile production plan in 2022. A major NATO procurement contract for up to 1,000 missiles followed in 2024, with a new production facility in Schrobenhausen set to supply both Ukraine and replenish depleted European alliance stockpiles.
But Ukraine faces a unique challenge that neither Japan nor Germany has had to contend with: constant, large-scale Russian strikes on Ukrainian industrial and infrastructure targets. Khrapchynskyi explained that any Patriot production facility in Ukraine would immediately become a top priority targeting for Moscow, meaning all production operations would have to be moved to heavily protected locations, likely underground or inside hardened blast shelters. This reality frames the license agreement as a long-term strategic investment rather than an immediate solution to Ukraine’s urgent frontline air defense needs. If successfully implemented, the licensing deal would position Ukraine as a future major producer of air defense weapons, reducing its reliance on Western allies that have already seen their own weapons stockpiles severely strained by months of donations to Kyiv. As Khrapchynskyi put it: “It would not solve the current missile shortage in 2026, but it would lay the foundation for Ukraine to become one of Europe’s leading producers of air-defense systems in the future.”
