Russian Sabotage Threat in Baltics Exposes NATO’s Air Defence Deficit

What appears at first glance to be another episode in the long-running confrontation between Russia and the West points to a larger problem. Latvia’s warning is not only about Russian intentions. It is also about NATO’s limited capacity to defend every vulnerable point on its eastern frontier.

Why These Targets Matter

Military planners often distinguish between symbolic targets and systemic targets.

The Riga hydroelectric facility and the Inčukalns gas storage complex belong firmly in the second category.

An attack on either site would affect daily life almost immediately. Electricity disruptions, pressure on energy supplies and fears about further attacks could spread far faster than any physical damage. Hybrid warfare seeks precisely this outcome: maximum political effect from relatively limited action.

For Moscow, if such an operation were ever attempted, the attraction would be obvious. Damaging infrastructure creates uncertainty without crossing the threshold of conventional military conflict. The objective would not necessarily be destruction. It would be disruption.

That distinction matters.

A missile strike on a NATO city would almost certainly trigger an overwhelming alliance response. A drone incident, sabotage attempt, cyberattack or unexplained infrastructure failure creates a much murkier political environment. Governments must determine responsibility. Allies debate proportional responses. Public anxiety grows.

The grey zone between peace and war is where modern hybrid operations thrive.

The Political Shadow of the Drone Crisis

Latvia's current government is operating under unusual pressure because security failures have already produced political consequences this year.

The previous coalition collapsed after public controversy surrounding stray Ukrainian-origin drones that entered Latvian territory from Russian-controlled areas. The incident exposed weaknesses in security procedures and generated public concern over how effectively the state could monitor and respond to aerial threats.

The significance of that episode was not military.

The drones themselves were relatively minor compared with the weapons used daily in Ukraine. What proved damaging was the perception that authorities lacked control over events unfolding in Latvian airspace.

That perception helped bring down a government.

Now an election is approaching in October. Any major security incident before voters go to the polls would inevitably become a political issue. Hybrid operations do not need to alter election results directly to achieve strategic goals. Creating confusion, undermining confidence in state institutions and amplifying domestic tensions can be sufficient.

For Kulbergs, protecting infrastructure and protecting political credibility have become closely connected tasks.

NATO’s Promise Meets Military Reality

The deeper story lies in the gap between NATO's commitments and the resources available to fulfil them.

Following Russia's full-scale invasion of Ukraine, NATO repeatedly pledged stronger protection for its eastern flank. At the Vilnius Summit, allies agreed on a rotational air-defence model intended to strengthen Baltic security.

On paper, the concept appeared practical. Allied countries would rotate advanced air-defence systems into frontline states rather than permanently stationing them there.

The difficulty is not political commitment.

The difficulty is inventory.

Europe simply does not possess enough high-end air-defence batteries to maintain continuous coverage everywhere they are needed. Patriot systems remain in high demand. SAMP/T batteries are limited. Existing systems must simultaneously protect national territories, support NATO missions and help Ukraine.

As a result, rotational deployments often provide temporary reassurance rather than permanent protection.

Lithuania's current deployment of Patriot batteries demonstrates both the value and the limitation of the model. The systems strengthen regional defence while present. They cannot remain everywhere indefinitely.

Latvia's situation reveals the consequence. Despite years of discussion about strengthening NATO's eastern frontier, the country still lacks permanently stationed long-range air-defence coverage for critical infrastructure.

That reality is increasingly difficult to conceal behind summit declarations.

Building a Layered Shield

The response emerging in Latvia represents a broader shift occurring across NATO's eastern members.

For decades, deterrence largely rested on reinforcement. The assumption was that allies would come quickly if a crisis emerged.

Today, frontline states are increasingly focused on surviving the opening stages of any confrontation themselves.

This is driving the development of layered defence systems.

The long-range layer consists of allied capabilities such as Patriot batteries. Medium-range coverage comes from national acquisitions like Latvia's planned IRIS-T SLM systems. Closer protection relies on anti-drone technologies, electronic warfare and rapid-response units capable of protecting individual facilities.

No single system can solve the problem.

A hydroelectric dam requires protection from cruise missiles, drones, sabotage teams and cyber threats simultaneously. Gas infrastructure faces similar vulnerabilities.

Layered defence is less elegant than traditional deterrence theory. It is also far more practical.

Ukraine’s Unexpected Role

One of the more striking developments is the growing influence of Ukrainian defence expertise on NATO's eastern flank.

Latvia is seeking NATO integration for anti-drone systems developed with Ukrainian assistance. This reflects a broader trend that has accelerated throughout the war.

Ukraine has become Europe's largest laboratory for drone warfare and electronic countermeasures. Technologies that once seemed experimental are now tested daily under combat conditions.

For countries such as Latvia, Ukrainian experience offers something Western defence industries cannot easily replicate: real-time adaptation against a constantly evolving threat.

The relationship is also changing perceptions within NATO.

Ukraine is no longer viewed solely as a recipient of security assistance. It is increasingly becoming a provider of military knowledge and technological innovation.

That shift carries strategic significance well beyond Latvia.

Divisions Inside Europe

Security concerns in the Baltic region are colliding with a different debate unfolding inside the European Union.

Kulbergs has criticised member states that continue to resist tighter restrictions on Russian energy interests, including opposition to the proposed twenty-first sanctions package targeting Russian LNG and elements of the so-called shadow fleet.

The disagreement highlights an increasingly visible divide.

For Baltic governments, the war is viewed through the lens of physical security and national survival. Every loophole in sanctions policy is seen as a source of funding that ultimately strengthens Russian military capabilities.

Elsewhere in Europe, economic calculations often remain more prominent.

The tension is not new, but it is becoming harder to manage as frontline states demand stronger measures while some governments continue balancing security concerns against commercial interests.

From Riga's perspective, the debate is not theoretical. The infrastructure now under heightened protection represents assets that could become targets precisely because Russia can exert pressure through methods that fall below the threshold of open conflict.

The Search for a “Quick Win”

The concern expressed by Latvian officials is rooted in a broader assessment of Russian behaviour.

As the war in Ukraine continues to consume military resources, opportunities for dramatic battlefield breakthroughs remain limited. Hybrid operations offer a different route to strategic impact.

A successful provocation in Latvia would not need to involve large-scale destruction. It could consist of a cyberattack that interrupts energy distribution, a drone incident near critical infrastructure, a sabotage attempt against a key facility or a coordinated disinformation campaign surrounding such an event.

The goal would be psychological as much as operational.

Could NATO protect its members? Could governments maintain control? Would public confidence hold?

Those questions are precisely why the security measures around the Riga dam and the Inčukalns storage facility matter far beyond Latvia itself.

The warning coming from Riga is less about a specific threat than about a structural reality: on Europe's eastern frontier, infrastructure is becoming a frontline, and the alliance charged with defending it still lacks enough shields to cover every target.
