Ukrainian drone operators who have spent years refining tactics against Russian forces are now sharing that hard-won battlefield expertise with NATO allies, participating in large-scale exercises designed to defend Sweden's strategically vital Gotland island—often described as an unsinkable aircraft carrier in the Baltic Sea.
Aurora 26, which ran from April 27 through May 13, involved over 16,000 Swedish troops alongside forces from 11 allied nations and Ukraine, according to United24 Media. The exercises encompassed land, naval, and air operations across Sweden and the Baltic Sea region, testing the alliance's ability to rapidly reinforce vulnerable positions in a conflict scenario.
Ukrainian participation through the UK-led Joint Expeditionary Force partnership framework represents more than symbolic solidarity. These are operators who have faced the Russian military daily for over three years, developing countermeasures and tactics that NATO forces have primarily studied in theory.
Ukraine's Combat-Tested Expertise
"Ukrainian drone operators reportedly led parts of the unmanned systems training component during the exercises," according to the Swedish Armed Forces. The role reversal—Ukraine teaching NATO rather than receiving instruction—reflects how the war has transformed Ukrainian forces into the most experienced practitioners of modern drone warfare.
Ukrainian teams also trained Swedish units on countermeasures against explosive-dropping drones, tactics refined through brutal necessity as Russian forces employ commercial and military drones to attack everything from infantry positions to rear-area logistics hubs. The dropping of munitions from small commercial drones has become one of the most prevalent and deadly features of the Ukraine conflict, killing thousands of soldiers on both sides.
These techniques—identifying drone operators through signal detection, employing electronic jamming, using net guns and trained raptors, and implementing dispersion tactics to minimize casualties—were developed through trial, error, and tragic losses. NATO forces now benefit from this knowledge without paying the same price in blood.
Gotland: The Baltic's Strategic Pivot
The exercise focused on "reinforcing and defending Gotland, the strategically located island viewed as central to NATO's defense posture in the region." The island, Sweden's largest, sits in the middle of the Baltic Sea approximately 90 kilometers from the Swedish mainland.
Military planners describe Gotland as an aircraft carrier that cannot be sunk. Control of the island would allow a hostile power to dominate air and sea approaches across the Baltic, potentially cutting Estonia, Latvia, and Lithuania off from reinforcement and threatening Poland's northern flank.
Conversely, in NATO hands, Gotland serves as an unsinkable platform for air defense systems, anti-ship missiles, and surveillance assets that can monitor vast expanses of the Baltic. The island's geographic position makes it the single most important piece of terrain for Baltic Sea control.
Sweden demilitarized Gotland in the 2000s, a decision later recognized as premature given Russian military modernization. Following Russia's 2014 annexation of Crimea, Swedish forces returned to the island permanently, rebuilding defenses that had been dismantled.
The Rapid Reinforcement Challenge
A key operational objective of Aurora 26 involved "rapid deployment of allied forces from mainland Sweden to Gotland." Exercise commander Rear Admiral Jonas Wikström emphasized that success requires "ensuring that units arrive in the right place, at the right time, and with the right capabilities."
This seemingly straightforward requirement presents enormous logistical complexity. Moving thousands of troops with their equipment, ammunition, and supplies across 90 kilometers of open water while potentially under air and naval attack represents one of the most challenging military operations. Sweden maintains limited amphibious transport capacity, requiring allied assistance to move significant forces to the island in crisis.
The exercises tested coordination between Swedish, NATO, and partner nation forces—ensuring communications systems interoperate, understanding different tactical doctrines, and practicing the unglamorous but critical logistics that determine whether reinforcements arrive in fighting condition or piecemeal and disorganized.
NATO's Baltic Vulnerability
The Baltic states—Estonia, Latvia, and Lithuania—represent NATO's most vulnerable territory. The Suwalki Gap, a narrow stretch of Polish territory connecting the Baltic states to the rest of NATO, could potentially be cut by Russian and Belarusian forces, isolating the three nations.
Defending the Baltic states requires both credible conventional forces positioned to deter aggression and the ability to rapidly reinforce if deterrence fails. Control of the Baltic Sea and air space is essential for such reinforcement, making Gotland's defense a prerequisite for honoring NATO's Article 5 collective defense commitments to its northeastern members.
Russia maintains significant military forces in its Western Military District and Kaliningrad exclave, positioned to threaten the Baltic region. While the war in Ukraine has degraded Russian conventional capabilities, Moscow retains substantial air and naval assets in the region, including advanced anti-access/area-denial systems.
Sweden and Finland's NATO Accession
Sweden's recent accession to NATO, completed in 2024 along with Finland, fundamentally transformed Baltic security dynamics. What was once a semi-enclosed sea with NATO members controlling only portions of the coastline is now overwhelmingly dominated by alliance members.
Finnish and Swedish membership extends NATO's defensive perimeter significantly northward, complicating Russian military planning and providing new bases for allied forces. However, integrating two new members with distinct military traditions and equipment requires extensive exercises like Aurora 26 to build genuine interoperability.
The Ukraine Partnership
Ukraine's participation in Aurora 26, while not reflecting NATO membership, demonstrates the alliance's commitment to deepening practical cooperation with Kyiv. The Joint Expeditionary Force framework, led by the United Kingdom, provides mechanisms for engaging partners who are not full NATO members.
For Ukrainian forces, the exercises offer opportunities to train alongside potential future allies using their equipment and doctrine. For NATO, Ukraine provides access to personnel who understand Russian military capabilities and tactics from direct combat experience—knowledge that no amount of theoretical study can replicate.
The integration of Ukrainian drone warfare expertise into NATO exercises represents a preview of broader military transformation. The war in Ukraine has demonstrated that small, inexpensive drones can fundamentally alter battlefield dynamics, forcing armies to rethink everything from infantry tactics to base security.
As one NATO official observed, "We're learning lessons from Ukraine in real-time and incorporating them into our doctrine and training. That's unprecedented." The presence of Ukrainian operators at Aurora 26, teaching Swedish and allied forces how to counter drone threats, exemplifies this knowledge transfer in action.
To understand today's headlines, we must look at yesterday's decisions. NATO's expanded focus on Baltic defense, Sweden and Finland's membership applications, and integration of Ukrainian combat experience all stem from Russia's decision to invade Ukraine in 2022. That choice triggered the most significant reconfiguration of European security architecture since the end of the Cold War—one whose full implications will shape the continent for decades.
