Rising tensions: The Kremlin prepares Kaliningrad for a potential blockade



The energy crisis in Crimea, caused by Ukraine’s regular strikes on infrastructure and logistics targets, has demonstrated the critical vulnerability of an isolated region of Russia. A similar problem could unfold in Kaliningrad Region, the Russian exclave which lies between Poland and Lithuania,. The region is heavily dependent on external supplies, making it Russia’s principal vulnerability in the event of a crisis. The Kremlin has been systematically preparing Kaliningrad to withstand isolation, and has significantly intensified its efforts in recent months.

A number of unusual steps taken by Russia’s senior leadership indicate that the federal government is revising contingency plans for the defence of Kaliningrad in the event of a complete blockade. On 1 July, Vladimir Putin held an extraordinary meeting with members of the Security Council about Kaliningrad Region. The meeting departed from the usual protocol for two reasons: it took place on a Wednesday rather than the customary Friday, and it was held in person – a format that the president uses only rarely.

The following day, Putin held an in-person meeting with the Governor of Kaliningrad Region, Alexey Besprozvannykh. The main issues they discussed were ensuring priority fuel supplies to the region and building up strategic reserves. It was under the leadership of Besprozvannykh, the former Deputy Minister of Industry and Trade of the Russian Federation, that the region’s power system was switched to fully autonomous operation in response to the simultaneous withdrawal of the Baltic states from the Brell (Belarus, Russia, Estonia, Latvia, Lithuania) power grid in early 2025. This move by the Baltic states was seen by Moscow as part of a plan to isolate Kaliningrad from Russia. 

The strong possibility of a confrontation between Russia and NATO in this theatre is reflected in the extremely tense relations between Moscow and its Baltic neighbours. Russian authorities regularly accuse the Baltic states of Russophobia, of militarising the region through the build-up of NATO forces, and of directly assisting Ukraine – in particular, by allowing Ukraine to use their airspace to carry out drone strikes on Russia. 

Against this backdrop, there is growing speculation that the Kremlin may be preparing a possible provocation in the Baltic region to demonstrate the ineffectiveness of NATO’s Article 5 and compel Western countries to end their support for Ukraine, while avoiding a full-scale conventional war. This could involve limited drone attacks on critical infrastructure or simulated air strikes designed to force the activation of allied air defence systems. One element of the information campaign preceding such a provocation was the recent promotion via social media of the narrative of a ‘Narva People’s Republic’ in the predominantly Russian-speaking city of Narva, on Estonia’s border with Russia, closely replicating the model used in Donbas in 2014.

In response to this kind of aggression, Moscow believes that NATO would be highly likely to isolate Kaliningrad Region by closing its land and maritime borders. Kaliningrad would face prolonged isolation until the blockade could be lifted, most likely via the opening of an overland supply route from Belarus through the Suwałki Corridor – a process that could take many months.

The growing tensions around Kaliningrad coincide with a temporary weakening of NATO force deployments in the Baltic region. The United States is reviewing its military presence in Europe: more than 1,000 US troops have left Lithuania as part of a routine rotation, while the timetable for the arrival of replacement units remains unclear. The core contingent of the NATO battlegroup in Estonia numbers around 1,000 personnel. At the same time, Germany is permanently establishing the 45th Armoured Brigade of the Bundeswehr in Lithuania, with a planned strength of approximately 5,000 personnel. The brigade is expected to assume part of the role currently performed by US forces, but it will not reach full operational capability until the end of 2027. 

As a result, for at least the next 18 months, the Russian leadership believes that the region will remain in a transitional period characterised by a reduced NATO presence and uncertainty about Berlin’s political willingness to deploy its forces due to concerns about further escalation.
