Two Russian submarines and a follower ship pass through the Storeb ællt heading north today. A third submarine from the group is anchored up south of Langeland and is expected to continue later.
The passage of foreign submarines in Denmark is a normal procedure and happens completely without drama. The defense usually follows closely. Also in this case, where a Danish ship from the Nav værrnet follows the submarines.
The submarines will sail on the surface all the way. It is part of the conditions for harmless passage. If the ships sail individually through Danish waters, they are not obligated to report their passage to Denmark. But if more than three ships sail together, they must alert their sailing of the straits to the Danish authorities.
The submarines are of the KILO class, which are diesel-electric submarines, where a diesel engine operates electric engines and charges batteries for sailing underwater.
