“This is not a normal exercise. The operation is taking place for real, and the forces are protecting the transports with live ammunition.” This blunt assessment by Swedish Navy Officer Manne Schagerström to public broadcaster SVT underscores the significance of Silver Wotan 2026, a pivotal bilateral military exercise currently underway on the strategic island of Gotland.
While Sweden and Germany have conducted joint maneuvers in the past, this latest iteration carries unprecedented weight. The drills take place against the backdrop of persistent tensions between NATO and Moscow and heightened fears of potential Russian hybrid threats along the alliance’s northeastern flank.
The 10-day bilateral exercise, which began on September 14, involves approximately 1,500 Swedish and German personnel. It marks a critical step forward in bilateral defense integration, testing how Allied reinforcements would blend into Gotland's permanent defense architecture during a contingency scenario.
Securing the 'Unsinkable Aircraft Carrier' of the Baltic
Rapid Deployment from Karlskrona to Visby
The core of Silver Wotan centers on the rapid sea-and-air transit of heavy weaponry from Karlskrona—the Swedish Navy’s primary naval base—to Visby, Gotland’s main port. The transport vessels are heavily escorted by a joint task group of Swedish and German surface combatants, including frigates and corvettes, supported by coastal artillery units and frontline fighter jets.
Deploying Strategic Assets: Anti-Ship and Air Defense Systems
The cargo deployed to the island includes advanced air defense systems and coastal anti-ship cruise missiles (ASCMs). In a conflict scenario, these mobile assets are vital to enforcing Anti-Access/Area Denial (A2/AD) bubbles. Gotland’s unique geography turns the island into a natural sentinel, offering NATO a massive advantage in regional maritime and airspace surveillance, as well as layered theater denial capabilities.
Geopolitical Vulnerabilities and the Shadow of Kaliningrad
Despite its strategic value, Gotland’s location presents significant operational challenges. Surrounded by shallow Baltic waters and situated in close proximity to the Baltic states and Russia’s heavily militarized Kaliningrad exclave, the island remains exposed. Defense planners must constantly balance its vulnerabilities—particularly regarding potential Russian hybrid operations or sabotage—against the logistical difficulties of sustained maritime maneuvering.
Stockholm officials emphasize that Silver Wotan was planned well in advance and does not respond to a specific, immediate Russian threat. However, regional security experts note that the context is impossible to ignore. Gotland has long been a foundational pillar of Swedish defense policy, but its importance has deepened following Sweden’s formal accession to NATO in 2024. Since then, Allied military planners have viewed the island as a critical asset for any prospective defense blueprint of the Baltic theater.
Germany’s Commitment on the Northeastern Flank
Berlin's Expanding Defense Role
Germany’s heavy footprint in Silver Wotan signals Berlin’s increasing defense role along NATO’s northeastern flank. Furthermore, as European capitals navigate the unpredictability surrounding Washington's foreign policy shifts under the Trump administration, testing joint reinforcement plans allows both nations to enhance their shared capabilities and streamline the logistics necessary for regional deterrence.
Luftwaffe and Marine Deployments
Germany’s contribution to the exercise spans all operational spheres:
- Air Domain: The Luftwaffe has deployed Panavia Tornado combat aircraft to secure the airspace and practice combat air patrols (CAP).
- Maritime Domain: The Deutsche Marine is providing frontline surface combatants for high-value unit (HVU) escort missions.
- Land Domain: Over 500 German ground troops are stationed in Visby to reinforce force protection.
In addition, open-source flight tracking data recorded a German Airbus A400M Atlas transport aircraft operating in the airspace between Kalmar and Gotland on Friday.
Integrating with Gotland's Permanent Defenses
Upon arrival, German forces integrated with the Swedish P18 Gotland Regiment. Formed as part of Stockholm’s remilitarization efforts on the island, this unit serves as the permanent backbone of Gotland's ground defense, designed specifically to hold the line until Allied reinforcements arrive.
“We want to send a clear message to those who threaten our peaceful communities and our countries," stated Alexander Sollfrank, Chief of Operations for the German Armed Forces. "Sweden and Germany are neighboring countries, and we want to demonstrate our determination to defend this island in a very short time.”
Reflecting the sensitive nature of the drills, operations on the ground are backed by tight security protocols to maintain operational safety. The Swedish Police are working alongside military authorities, utilizing surveillance drones to secure the area and counter potential foreign reconnaissance or unauthorized monitoring throughout the maneuvers.
