The United States has for decades operated a clear framework for sharing missile technology with allies, but the record shows that extending full co-production rights for a major air defense system like the Patriot to a non-NATO country would break long-standing precedent. Such a move would require a waiver under the Arms Export Control Act, a federal law that sets strict limits on the transfer of production know-how for advanced defense articles.
The question now is whether the current administration under President Donald Trump, with Vice President JD Vance and Secretary of State Marco Rubio, will pursue that legal pathway for Ukraine.
Historical Co-Production: A Pattern of Restraint
The United States has co-produced missile systems with its allies for decades under licensing agreements that share technology but do not transfer it outright, officials confirmed. The FIM-92 Stinger, a shoulder-fired short-range weapon produced by Raytheon, has been built under license in Germany and Turkey.
The AIM-9 Sidewinder air-to-air missile has seen production in Japan, Germany, and the United Kingdom. These programs demonstrate a consistent pattern of limited technology sharing within a circle of trusted partners—primarily NATO allies and major non-NATO security partners. The Patriot air defense system itself has been co-produced in Japan since the 1990s, with Mitsubishi Heavy Industries manufacturing components under license. In 2015, the United States approved the sale of Patriot systems to Qatar, which included technology transfer for maintenance purposes.
Officials confirmed that these arrangements have remained within the boundaries of NATO allies or major non-NATO security partners. The most extensive co-production program on record is the F-35 Joint Strike Fighter, which involves partners in the United Kingdom, Italy, the Netherlands, and others.
That program represents a multi-billion-dollar industrial partnership, not a simple transfer of finished systems. The Patriot is a mobile air defense system that tracks and engages aerial threats. Its technology includes sophisticated radar, command-and-control software, and interceptor missiles—making it one of the most advanced systems the United States exports.
U.S. missile systems are guided weapons designed to destroy aircraft, drones, or incoming missiles, ranging from shoulder-fired short-range weapons like the Stinger to large, truck-mounted systems like the Patriot.
Legal Hurdles and Strategic Implications for Ukraine
The strategic context for any potential co-production arrangement with Ukraine is fundamentally different from past partnerships. According to the statement of established policy, a full technology transfer for a major air defense system like the Patriot to a non-NATO country would be unprecedented.
Such a move would require a waiver under the Arms Export Control Act, which governs the transfer of defense articles and services. A waiver for a non-NATO country would represent a significant shift in U.S. policy, officials confirmed. The legal and political hurdles are substantial, and the decision would carry implications for alliance management across Europe and Asia.
For decades, the United States has maintained that full co-production rights are reserved for its closest allies. The Arms Export Control Act sets strict limits on sharing production know-how, especially for a major integrated system like the Patriot.
Any shift would test the limits of a legal framework designed during the Cold War to keep critical military technology out of foreign hands.
Why the Precedent Matters
The strategic calculus involves balancing support for Ukraine against the risks of setting a precedent for technology transfer that could alter the global defense industrial landscape. The rules governing missile technology reflect broader decisions about national security and alliance networks.
Shifting those rules could mean a fundamental change in how the United States partners with countries outside its traditional treaty alliances. The outcome would affect not just Ukraine, but the way the United States approaches defense cooperation with other non-NATO nations in the future. The decision ultimately rests on whether the administration will pursue a waiver under the Arms Export Control Act. The legal and political hurdles are substantial, and the implications for alliance management across Europe and Asia are significant.
The record remains clear: full technology transfer for a major air defense system to a non-NATO country would break a precedent that has held for decades.
