Continuation of unexploded ordnance neutralization in the Gulf of Gdańsk. Water entry ban from Stogi to Sobieszewo
From March 19 to 21, a large-scale operation to neutralize unexploded ordnance (UXO) lying on the seabed of the Gulf of Gdańsk will take place. Due to the operation, a temporary ban on entering the water has been imposed on Gdańsk's beaches, covering the stretch from entrance No. 26 (Stogi) to entrance No. 11 (Orle) on Sobieszewo Island.

UXO in the Gulf of Gdańsk – Scale of the threat and the need for clearance
A significant number of unexploded ordnance, remnants of military operations from World War II, remain on the seabed of the Gulf of Gdańsk. This phase of the operation will neutralize approximately 100 artillery shells and one aerial bomb, totaling nearly 1,200 kg of explosive materials. These objects pose a threat not only to navigation and fisheries but also to the marine environment.
This operation is a continuation of actions initially conducted from March 11 to 14, 2025, which had to be suspended due to unfavorable weather conditions in the Gulf of Gdańsk.
How is UXO neutralization conducted at sea?
The neutralization will be carried out by combat divers from the 13th Minesweeper Squadron, named after Fleet Admiral Andrzej Karweta. The operation involves transporting the UXO to a controlled detonation site located at a depth of approximately 20 meters, about 5 km offshore. Residents and visitors may experience noticeable tremors and hear explosions during the operation.
To ensure public safety, from 9:00 AM to 4:00 PM, the area will be patrolled by officers from the Police, Municipal Guard, and Territorial Defense Forces. Information boards warning about the water entry ban will also be placed on the beaches.
Impact of UXO detonations on the marine environment and economy
Underwater detonations can temporarily disrupt the marine ecosystem. Experts are closely monitoring the impact on flora and fauna and are taking measures to minimize potential adverse effects. The operation is also crucial for maritime economy—removing these hazardous objects will enhance navigation safety and allow for further development of port infrastructure.
Important information and recommendations for residents and tourists
Local authorities and emergency services urge the public to comply with the restrictions and refrain from entering the water in the designated area. It is also recommended to follow updates from local authorities and media outlets.
The UXO neutralization operation is another step toward improving the safety of Polish territorial waters. Although such activities are complex and require extensive expertise, their results contribute significantly to the security of maritime operations and coastal recreational areas.
