NATO’s weapons, training and procurement systems may not be keeping pace with the rapidly evolving, drone-dominated warfare seen in Ukraine, according to a Reuters investigation published on 17 September 2026. The report, based on interviews with five Ukrainian and Western defense officials, describes a widening gap between Ukraine’s battlefield improvisation and the alliance’s slower institutional pace.

Weeks versus decades

Ukraine, which is not a NATO member, has had to adapt its weapons and tactics within weeks to survive against Russia, Reuters reported. NATO’s own development and procurement cycles, by contrast, often take years or even decades to move from concept to battlefield deployment. That mismatch is at the heart of the concerns raised by officials interviewed for the investigation.

Denys Shtilerman, co-owner and chief designer of the Ukrainian drone and missile maker Fire Point, told Reuters that inexpensive drones costing around $5,000 can now destroy tanks worth vastly more, a shift he says renders traditional armor ‘worthless’ in some combat scenarios. Not all military analysts agree entirely, with many still seeing a continued role for tanks on the battlefield. But the broader point, that cheap drones have made troop concentrations and large convoys far easier to target, is widely echoed in the report.

Estonia’s frontline exercises

Reuters journalists observed a NATO exercise near Paldiski, Estonia, in June, where American and European troops practiced treating simulated casualties under wartime field conditions. Estonia, a small Baltic member state bordering Russia along roughly 210 miles of frontier, has been fortifying its defenses as a frontline NATO state.

The Wall Street Journal separately reported that during NATO’s 2025 ‘Hedgehog’ exercise in Estonia, which involved more than 16,000 service members from about a dozen NATO countries, Ukrainian drone operators outperformed their allied counterparts. Brigadier Giles Harris, who commands the UK contribution to NATO’s enhanced Forward Presence mission in Estonia and Poland, said the stakes of adapting quickly are high.

Reducing reliance on the US

The investigation also points to Europe’s push to develop alternatives to American air-defense systems such as Patriot, driven by concern that heavy reliance on U.S. equipment could become a strategic vulnerability. Ukraine is awaiting delivery of the French-Italian SAMP/T-NG system, designed to intercept ballistic missiles, which France has pledged to accelerate. European diplomats have previously told Reuters it was expected to arrive by around spring of next year.

Shtilerman argued that financial investment alone is not enough without independent control over the technology. ‘If you spend $20 billion on your air defense system, you must be independent in your security,’ he told Reuters. The comments come as the Pentagon reviews its military footprint in Europe, amid pressure from U.S. President Donald Trump on NATO allies to increase defense spending and reduce dependence on American protection.
