These include the landing ships Alexandr Otrakovsky (Ropucha-class) and Ivan Gren (Ivan Gren-class), the supply ship Yelnya (Altay-class), the oil tanker General Skobelev, and the transport ships Sparta and Sparta II.
The 6 ships were guided through the so-called Dutch Exclusive Economic Zone. After the passage, other NATO partners took over the escort. The navy deployed HNLMS Johan de Witt for the escort. The maritime helicopter NH90 was also used.
Right of Passage
Russian units frequently navigate through the Dutch Exclusive Economic Zone. There is an internationally agreed right of passage here. Nevertheless, the Netherlands escorts such fleet formations. This is not only to remain vigilant but also to intervene in case of suspicious actions or disturbances. Defence thus protects critical underwater infrastructure.
