In brief

Eleven NATO warships from seven nations moored at the Obrońców Westerplatte Quay in the Port of Gdańsk for a working visit to resupply and rest crews. The vessels fly the flags of Lithuania, Latvia, Estonia, Germany, Sweden, the Netherlands and Belgium, led by the German replenishment ship FGS Mosel (A512), 100 metres long. NATO units engaged in Baltic MCM exercises and Operation Baltic Sentry protect undersea cables and energy installations in the Baltic Sea. The ships can be viewed until Monday 7 April.

The warships, flying flags of Lithuania, Latvia, Estonia, Germany, Sweden, the Netherlands, and Belgium, are led by the German FGS Mosel (A512). Currently engaged in Baltic MCM exercises, these NATO ships underscore the Alliance’s commitment to maritime security. Their presence ensures a safe environment for Baltic Sea transport and trade, reinforcing solidarity among member states.

Moored at the Obrońców Westerplatte Quay in Gdańsk Port, the 11 vessels were greeted by Lt. Daniel Drewniak of Poland’s 8th Coast Defense Flotilla. Visitors can view the ships until Monday, April 7. The FGS Mosel, an Elbe-class replenishment vessel, is the largest at 100 meters long, 16 meters wide, and a 4-meter draft. It supports naval autonomy by delivering fuel, provisions, ammunition, and medical services. Other ships, like the Swedish minehunter HSwMS Ulvön (47 meters), are part of SNMCMG1.

Operation Baltic Sentry: NATO’s Baltic Sea Strategy

Launched in January 2025 during the Baltic Sea States Summit in Helsinki, Operation Baltic Sentry enhances NATO’s presence in this strategic region. “NATO is prepared to defend Baltic Sea underwater infrastructure,” the Alliance stated, deploying SNMG1 and SNMCMG1 units, reconnaissance aircraft, and maritime drones. This operation boosts deterrence and response capabilities against threats like sabotage, often linked to Russia’s “shadow fleet.” A notable incident—last year’s damage to a Helsinki-Rostock cable—underscored the need for this initiative. Rotational patrols target areas near undersea cables and energy installations.

Poland’s Operation Gulf: Protecting Baltic Assets

Since 2023, the Polish Navy’s Operation “Zatoka” (Gulf) has monitored Poland’s territorial waters and exclusive economic zone. Focused on safeguarding underwater infrastructure—gas pipelines, telecommunications cables, and oil terminals—this mission counters rising sabotage risks in the Baltic Sea. Triggered by events like the Nord Stream incident, Polish ships maintain constant vigilance over critical maritime assets.
