Swedish island of Gotland prepares for potential Russian attack amid remilitarisation
Gotland prepares for potential Russian attack

Only four months ago, Ella Adman had just finished school and had never before held a gun. Now, standing in the shade between drills at a military base on Gotland, the strategically important Swedish Baltic island where she grew up, the 19-year-old conscript carries a powerful assault rifle. In days, she is due to carry out her first official mission in Stockholm, guarding the royal family.

Conscription and remilitarisation on Gotland

Adman is one of hundreds of conscripts sent to the base near the medieval walled city of Visby as part of a rapid remilitarisation process on Gotland, a popular summer holiday destination for Swedes, amid the country's wider rearmament. At the height of the cold war, Gotland had four regiments and at full mobilisation a strength of 25,000 soldiers. But in 2005 the last of its regiments, P18, was closed, leaving only a reduced Home Guard battalion.

Positioned 275km from Kaliningrad – the militarised Russian exclave between Lithuania and Poland – and 87km from the Swedish mainland, Gotland is seen as ideally positioned for the Russian president, Vladimir Putin, to get a foothold in the Baltic, sometimes referred to as the “Nato sea”. As Sweden's largest island, home to 60,858 people and host to the country's political leaders for Almedalen, an annual democracy festival, an attack would have huge symbolic significance.

Strategic importance and Nato integration

In Swedish defence plans for 2025-30, a surprise attack on Gotland – either by air or sea aimed at setting up air and naval defence zones – was named as one of seven potential situations requiring prioritised planning. According to Swedish defence chiefs, from Gotland it is possible to control sea and air operations in the Baltic Sea region and to control the entrance of reinforcements to Baltic states.

“If you are able to control Gotland, you are able to control the Baltic Sea as well,” said Col Andreas Gustafsson, the commanding officer for the Swedish army in Gotland. “So we need to keep control of Gotland – for Sweden, but also for Nato's sake.” Since being re-established in 2018, P18 has been built up at unprecedented speed, accelerated by Russia's full-scale invasion of Ukraine. Since Sweden's accession to the alliance, the island is becoming a regular host for Nato training exercises.

Challenges of rearmament

Despite Sweden upping its defence contributions to 2.8% of GDP for 2026 and 3.1% from 2028, rearmament is proving difficult, said Gustafsson. “Nato is currently in a major growth phase, which means everyone is out looking for military hardware which means it takes time to get hold of military equipment, particularly artillery systems, and acts as a limiting factor for expanding our capabilities.”

For now, there is not an immediate threat of a “conventional attack” on Gotland, said Gustafsson, with espionage and sabotage more likely, but it cannot be ruled out. The island could be particularly vulnerable in the event of a ceasefire or peace deal with Ukraine, in which case Russian forces could be quickly redispersed towards Finland and the Baltic states. “The risk is always that Russia becomes desperate. The more pressure Russia is under, the more desperate they can be as well.”

Civilian defence initiatives

If Russia were to attack, Sweden plans to defend itself and keep its civilians largely in place. When mobilised, the combat group to protect Gotland is about 4,500. “Of course, we would defend Gotland and do all we can to stop Russia getting a foothold on Gotland,” said Gustafsson. But the hope is that remilitarisation will act as a sufficient deterrent, and Gotland is also acting as a test platform for defending the whole of Sweden, particularly in a civilian capacity.

Eva Rinblad, a doctor, has long been interested in self-sufficiency at her rural Gotland home. A year ago, amid growing warnings from authorities, she decided to set up an emergency preparedness group in her neighbourhood. Following the advice of the Stark socken (strong parish) scheme, a Gotland-wide civil preparedness initiative, they started by carrying out a collective neighbourhood inventory of supplies including water, electricity and communication. Next they plan to map all available water sources.

Rinblad also plans to set up a local safety hub in case of emergency where residents can go for updated information, heat, cooking facilities, phone charging and overnight shelter. At home they have a dedicated food cellar, extensive fruit and vegetable patches shared with another family, chickens, ducks, solar panels and rain collection butts. If Russia were to attack tomorrow, Rinblad hopes local authorities would help the most vulnerable but that, if possible, wider society should continue daily life where possible.

Total defence approach

Later this year, Gotland will carry out a test emergency evacuation of several hundred people from one part of the island to another. Mikael Frisell, the director general of the Swedish civil defence and resilience agency (MSB), said: “We have a very serious world situation and we notice out on the Baltic Sea that it is an area in which we are very close to Russia and there are incidents both above and below the surface.” To ensure “total defence” of Gotland, Frisell said a military presence and a “strong and robust and resilient civilian defence” were needed. “If we have that it contributes to the whole of Nato's collective defence in this region.”

In case of attack, Gotland risks becoming “isolated” and having supply flows disrupted, said Frisell. “We are working to get Gotland to be as self-sufficient as possible as it is an island in the Baltic Sea.” As part of that, they are working on strengthening emergency services using findings from Ukraine, including handling mass casualties, managing unexploded ammunition and searching demolished buildings.

Friction and future outlook

Emil Edenborg, a Stockholm University professor who studies the changing role of the Baltic islands, said although most people supported the return of the military on Gotland, the changes had not been without friction. As well as discourse over building permits and implications to windfarm development, it was sometimes referred to as a “wet blanket on island life”. “Complaints are not so much about local armed forces but about Stockholm and bureaucrats, seen as neglecting the interests of islanders.”

Standing in Visby harbour as a ferry full of holidaymakers comes in, Per Wikberg, the preparedness strategist for Gotland, describes it as the “highway” to Gotland. While the island is well on its way to self-sufficiency, there is still much to be done. “You can never be finished,” he said. “When shit hits the fan, what happens then? Is our planning good enough or do we need to make changes?”
