Why war accelerates military technological change

Some of the most consequential technologies of the modern era emerged from periods of conflict. Radar accelerated during World War II as Britain searched for ways to detect incoming aircraft. The Cold War helped produce satellite navigation systems that later evolved into GPS, while the internet traces part of its origins to military research programs designed to ensure communications could survive a nuclear attack.

Yet the most important relationship between war and innovation extends beyond any individual invention. As military historian Michael O'Hanlon argued in a 2022 Brookings Institution report, technological breakthroughs alone rarely transform military capability. Innovation depends equally on an organization's ability to adopt, integrate, and employ new ideas effectively.

For much of the past four years, Ukraine has been viewed as a uniquely powerful laboratory for military innovation. The 2026 Israel-Iran war, however, suggests that Ukraine may be less an exception than part of a broader pattern. Despite significant differences in geography, military capabilities, and strategic objectives, both conflicts demonstrate how war accelerates innovation by concentrating conditions that rarely converge in peacetime: urgency, funding, political permission, and real-world testing.

Urgency and resources

War imposes a level of urgency that few other forces can replicate.

Ukraine provides perhaps the clearest contemporary example. A December 2025 commentary published by the Royal United Services Institute argued that the conflict has generated military and industrial lessons already influencing defense planning far beyond the war itself. Faced with immediate operational demands, governments and defense companies have pursued solutions on timelines rarely seen during peacetime.

Urgency alone, however, is rarely sufficient. Innovation also requires resources, and wars have a remarkable ability to unlock them.

Global military expenditure reached a record $2.89 trillion in 2025, according to the Stockholm International Peace Research Institute, marking the highest level ever recorded. Governments that might struggle to secure political support for ambitious research initiatives during peacetime often discover far greater financial flexibility when confronted with pressing security threats.

Following Russia's invasion of Ukraine, Germany announced a €100 billion defense modernization fund, one of the most significant shifts in German defense policy since the end of the Cold War. Ukraine, meanwhile, has directed substantial resources toward domestic defense production, particularly in the drone sector. Across the Middle East, the growing prominence of missile and drone warfare has accelerated investment in missile defense, integrated air-defense systems, and counter-drone capabilities.

Wartime spending does more than expand military capacity. It creates the financial conditions necessary for experimentation, allowing governments and industries to pursue projects that might otherwise be difficult to justify.

The freedom to experiment

Innovation requires not only urgency and resources, but also institutions willing to accept risk.

Under normal circumstances, procurement systems favor predictability, bureaucracies reward caution, and emerging technologies often face lengthy approval processes. Wartime conditions can reverse those incentives.

Ukraine provides a striking example. Faced with immediate operational demands, the government moved to support the rapid expansion of domestic drone production. According to a June 2026 analysis published by Just Security, a U.S.-based national security and law publication, Ukrainian production of first-person view (FPV) drones grew from roughly 3,000-5,000 units annually in 2022 to around 3 million in 2025. The country's defense industry now has the capacity to produce more than 8 million FPV drones per year.

Similar pressures emerged during the Israel-Iran war. According to a March 2026 Center for Strategic & International Studies (CSIS) assessment, Iran launched more than 500 ballistic missiles during the first three weeks of the conflict, creating immediate demand for new defensive capabilities and exposing air-defense networks to one of their most demanding operational tests in recent history. Reuters reported in May 2026 that Israeli defense contractor Elbit Systems was already developing new hardware designed specifically to counter drone threats based on lessons drawn from Hezbollah and Iranian operations.

Wartime innovation therefore often depends less on new technologies than on institutions' ability to adapt quickly.

Combat is the ultimate test

Urgency, funding, and institutional flexibility can accelerate innovation, but none can substitute for the feedback provided by combat itself.

A 2025 CSIS analysis argues that contemporary conflicts are increasingly defined by rapid cycles of experimentation and adaptation. The wars in Ukraine and between Israel and Iran have demonstrated how operational experience can accelerate technological refinement while quickly exposing concepts that fail to perform as expected.

Unlike laboratories, simulations, or military exercises, combat immediately reveals which ideas work, which fail, and which require further adaptation.

When war stifles innovation

Yet the relationship between war and innovation is more complicated than many popular accounts suggest.

Conflict can destroy research institutions, divert scientific talent, consume investment capital, and encourage short-term adaptation at the expense of long-term discovery. Countries devastated by war have often experienced decades of lost scientific and industrial capacity. World War II left large parts of Europe and Asia with damaged universities, destroyed laboratories, and displaced researchers. While some nations transformed wartime research into postwar innovation, others spent years rebuilding.

Russia provides a contemporary example of this tension. While the war in Ukraine has driven significant adaptation in military technology and defense production, it has also required enormous financial and industrial resources. Innovation increasingly becomes oriented toward solving immediate battlefield problems rather than pursuing longer-term scientific or technological breakthroughs.

The Soviet Union offers a similar lesson. Its achievements in rocketry, nuclear technology, and space exploration are often cited as evidence that military competition drives innovation. Yet many historians and economists argue that deeper structural weaknesses became apparent once Cold War military spending receded.

The historical lesson is not that war creates innovation, but that it concentrates the conditions that make innovation possible. Ukraine and the Israel-Iran war demonstrate how rapidly institutions can adapt when urgency, funding, political permission, and real-world testing align. They also raise a broader question: if those conditions are already understood, must societies continue relying on conflict to create them?
