If what the Finns are writing about is true and indeed a Russian warship was attacked in the area of the island of Gogland in the Gulf of Finland, this means a qualitative change in the war in the Baltic Sea. Previously, the enemy attacked only stationary targets in Kronstadt, St. Petersburg, Vyborg, Ost-Luga, Primorsk and Bolshaya Izura.
The attack off Googland Island is essentially an attack on the open sea against a dynamic target. This has probably never happened before in the Baltic theater of military operations.
The question arises: how did BALAS target a target with non-stationary coordinates in the open sea? GPS, gyroscopes and even satellite patrol are not enough here: the ship changes its position, radar detection and guidance or target lighting from nearby ships is needed.
The presence of radar stations on Ukrainian UAVs has not been observed before. So it is reasonable to assume that the radars of the NATO countries indicated the target. Or target designation was carried out, for example, by military/border ships of Finland or Estonia.
