The bill requires the Secretary of Defense, in coordination with the Secretary of State, to engage the Secretary General of NATO and NATO member states to develop and implement a strategy to rapidly field a multi-layered, integrated air defense system that would defeat unmanned aerial systems and deter Russian aggression against NATO, with a focus on the alliance’s eastern flank. The strategy must identify gaps in NATO defenses against unmanned systems, address impediments to using mass-produced, low-cost munitions and next‑generation technologies, and outline future actions for the United States and NATO allies over the next five years.
It also directs submission of the strategy to Congress within 90 days of enactment and requires an interim implementation report by March 15, 2027.
At a Glance
What It Does
The Secretary of Defense, in coordination with the Secretary of State and NATO, must develop and submit a strategy to rapidly field a multi-layered, integrated air defense system to defeat unmanned aerial systems and deter Russian aggression against NATO.
Who It Affects
NATO member militaries and defense ministries, U.S. DoD and State Department, allied defense industries, and Ukraine as a cooperative partner in defense efforts.
Why It Matters
Provides a formal, up‑to‑date plan for alliance air defense against UAS threats, clarifies responsibilities and funding needs, and sets a five‑year horizon for technology development and production coordination.

What This Bill Actually Does
The bill requires the Department of Defense to lead a coordinated effort with the State Department and NATO to develop a strategy that would rapidly field an integrated, multi-layered air defense system. The aim is to defeat unmanned aerial systems and deter Russian aggression against NATO, with particular attention to eastern flank member states.
The strategy must identify gaps in NATO’s current defenses, especially around low-cost munition effectiveness, the use of AI and high‑power microwave technologies, and allied command-and-control coordination. It also calls for outlining each nation’s and the U.S.’s future actions over the next five years to close those gaps, including increasing low-cost munitions production and expanding NATO’s mass-produced unmanned systems, potentially in cooperation with Ukraine.
The DoD must submit the strategy to Congress within 90 days of enactment and provide an interim progress report by March 15, 2027, detailing resource and authority gaps. The bill defines key terms like “NATO” and “appropriate congressional committees” and sets the scope for what counts as NATO air defense collaboration.

Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Integrated NATO air defense against unmanned aerial systems
This section obligates the Secretary of Defense to work with the Secretary of State to engage the NATO Secretary General and relevant policymakers to develop and implement a strategy. The aim is to rapidly field a multi-layered, integrated air defense system capable of defeating unmanned aerial systems and deterring Russian aggression against NATO, with emphasis on alliance members along the eastern flank.
Elements of the strategy
The strategy must (1) identify gaps in NATO’s defenses against unmanned systems—especially impediments to using mass-produced, low-cost munitions and to deploying AI and high-power microwave weapons, plus coordination and interoperability hurdles—and (2) describe current U.S. contributions and five-year plans to boost low-cost munition production, advance next-generation technologies, and expand NATO production of mass-produced unmanned systems (including cooperation with Ukraine). It also covers actions NATO and individual allies should take over the same period to address these impediments and reach the stated goals.
Submission to Congress
Not later than 90 days after enactment, the Secretary of Defense must submit the strategy to the appropriate congressional committees. The submission must identify required funding and policy changes to bolster NATO’s multi-layered defense against unmanned systems and any additional resources needed to carry out the initiatives described in the strategy.
Interim report on implementation
By March 15, 2027, the Secretary of Defense must provide a report to Congress detailing progress in implementing the strategy and any gaps in resources or authorities that hinder full execution.
Definitions
Definitions cover ‘Appropriate Congressional Committees’ (the defense and foreign relations committees) and ‘NATO.’ These definitions ensure the reporting and coordination obligations are clear and bounded to the designated bodies.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- NATO as an organization and its member states gain a clear, actionable plan for air defense against unmanned systems.
- Eastern flank NATO members (Estonia, Latvia, Lithuania, Poland, Romania) receive targeted attention and coordinated defense enhancements.
- Ukraine benefits from potential cooperation with NATO on unmanned systems and defense production capabilities.
- U.S. Department of Defense and State Department gain a formal framework for coalition-based defense planning and funding
- Defense industry players focusing on low-cost munitions, AI, and high‑power microwave technologies stand to participate in expanded procurement and development.
Who Bears the Cost
- U.S. defense budget and congressional appropriations must cover strategy development and capability upgrades.
- NATO member governments must align procurement and policy changes, which may require reallocation of defense resources.
- Defense contractors and suppliers must scale up production of low-cost munitions and advanced technologies, with associated transition costs and supply chain risks.
- Administrative costs for Congress and DoD to oversee reporting, coordination, and accountability exercises.
- Potential opportunity costs as funds shift toward NATO air-defense initiatives and related industrial base investments.
Key Issues
The Core Tension
Speed and depth of multinational integration versus sovereignty, budgetary realities, and the risk that rapid, joint fielding could outpace the ability of all parties to synchronize their policies, systems, and procurement.
The bill creates a high-stakes, multinational coordination challenge. It pushes rapid planning and alignment across diverse sovereign defense establishments, which can strain timelines and procurement cycles.
The reliance on five-year action plans and cooperation with Ukraine introduces political and operational uncertainties, including how funding will be appropriated and whether allied industrial bases can scale quickly enough to meet demand. An unresolved question is whether the strategy can effectively integrate AI and high-power microwave capabilities with existing NATO systems without triggering interoperability or escalation concerns across member states.
