Sir John Stringer delivered a blunt assessment in mid-June. The days when NATO could sit back, wait for threats to appear, and knock them from the sky with fast jets or pricey surface-to-air missiles have ended. Cheap drones and mass attacks now strain the old playbook. The NATO Deputy Supreme Allied Commander Europe spoke with Business Insider on June 21, 2026. His words landed as fresh reports highlighted American plans to cut fighter jet commitments to Europe.
The threat spectrum runs from low-cost uncrewed systems to hypersonic weapons. Stringer described it plainly. One end features inexpensive drones. The other includes air-launched ballistic missiles traveling at extreme speeds. Western forces once counted on technological superiority and deep stockpiles. Those assumptions face pressure from adversaries who launch volleys cheaper than the cost of interception.
Consider the numbers. A single Patriot Advanced Capability-3 missile runs about $3.7 million. Shahed-style one-way attack drones, supplied by Iran to Russia and others, cost between $20,000 and $50,000. Using the former against the latter proves unsustainable over time. Stockpiles dwindle. Replenishment takes years. And the math favors the attacker who can produce drones at scale.
Stringer drove the point home. “The most obvious example of getting that wrong would be using US-made Patriot air defense missiles against the kind of Shahed-style drones Iran and Russia are fielding. That’s unsustainable.” He added that Western militaries must build defenses at scale. The volume of incoming threats exceeds what current systems can handle affordably.
Recent events reinforce the warning. Russian-linked drones have crossed into NATO airspace on multiple occasions. U.S. Army air defenders from the 10th Army Air and Missile Defense Command discussed these incursions at Eurosatory 2026. They stressed the need for faster innovation along the eastern flank. The command’s new leader, Brig. Gen. Glenn Henke, assumed duties this month amid heightened activity. Stars and Stripes reported the change of command on June 18, 2026.
Meanwhile the United States signaled reduced support. Plans call for cutting the number of F-16 and F-15E fighter jets available to NATO in Europe from roughly 150 to 100. Maritime reconnaissance aircraft would drop from 26 to 15. All eight aerial refueling tankers previously committed would go away. The New York Times broke the story on June 12, citing senior European officials who reviewed the document. The move accelerates a broader American effort to scale back eight decades of protection.
European allies now confront hard realities. They cannot protect every city, base, and piece of infrastructure in a major conflict. Tough choices loom. Some targets will go undefended. Command centers themselves must disperse. Fixed, large facilities become easy prey for precision strikes or swarms. Stringer noted the requirement for more mobile, hardened coordination nodes.
Offense matters as much as defense. “Your defense needs a good offense,” the commander said. Striking launch sites, production facilities, and command chains prevents weapons from flying in the first place. Relying solely on shooting arrows proves insufficient. One must target the archers too. Ukraine’s experience shows the value. Kyiv developed cheap interceptor drones while Western partners scrambled to match production tempos.
Yet production shortfalls persist across the alliance. European systems such as IRIS-T, SAMP/T, and NASAMS exist. They have not scaled fast enough to offset demand for Patriot-class interceptors against ballistic and cruise missiles. A report from the Clingendael Institute in May 2026 outlined these gaps in detail. It highlighted how simultaneous demands from Ukraine, Israel, and potential NATO contingencies stretch finite supplies. The analysis warned that low-risk incursions by Russia could test alliance cohesion without triggering full collective defense.
NATO trains to meet the challenge. Exercise Ramstein Flag 2026 tested integrated air and missile defense across the northern flank. Finnish, Spanish, and other allies practiced sensor fusion, command links, and layered responses in Rovaniemi and beyond. Senior leaders observed how AWACS, deployable control centers, and multinational refueling units knit operations together. Similar drills focus on counter-drone technologies. Still, orchestration remains difficult. One expert likened current efforts to assembling ingredients without a chef directing the kitchen.
The 10th Army Air and Missile Defense Command pushes the Eastern Flank Deterrence Initiative. It seeks to connect sensors, shooters, networks, and decision makers more tightly. Uncrewed systems, live data feeds, and scalable effects form the core. Officials at Eurosatory emphasized seeing first, deciding faster, and striking effectively. These steps aim to close gaps identified in recent border violations.
Air superiority itself may prove fleeting. Stringer acknowledged that future fights against peer adversaries like Russia or China could allow only temporary control of the skies. Bursts of dominance rather than permanent command. The principle still underpins joint operations. Ground forces, naval units, and logistics all depend on some measure of protection from above.
European voices grow louder on the need for autonomous capacity. The International Institute for Strategic Studies published analysis in June 2026 arguing that European NATO holds substantial combat power in tanks, brigades, and artillery. The question is whether political will matches the inventories. Parliamentary assemblies within NATO stress increased defense spending and innovation. Estonia and Finland lead efforts on resilience. Southern flank concerns around migration and Mediterranean security add layers of complexity.
Industry must expand output. Ukraine demonstrated how nimble firms can pivot to wartime needs. Western defense contractors face backlogs in radars, launchers, and interceptors. Electronic warfare capabilities require parallel growth to jam or spoof incoming drones. Artificial intelligence could help prioritize threats, yet integration across 32 allies brings friction.
Stringer offered no easy fixes. The shift demands new thinking on cost curves, dispersal, and offensive action. It requires accepting that homelands once considered safe may face direct attack in large-scale war. NATO can no longer assume reactive defense suffices. The commander put it succinctly. Those days are over.
Fresh exercises and command changes show movement. Cuts in U.S. commitments add urgency. Allies now race to field layered defenses that mix cheap counters with high-end systems. They must coordinate at speed across domains. Failure carries steep risks. The skies over Europe have grown contested. NATO’s response will shape deterrence for years ahead.
