Commander of the Royal Netherlands Navy

The Commander of the Royal Netherlands Navy () (CZsk) is the highest-ranking officer of the Royal Netherlands Navy. The CZsk reports directly to the Chief of the Netherlands Defence Staff.
The position of CZsk was created on 5 September 2005, following a large overhaul of the command structure of the Dutch armed forces. In this overhaul the position of "Bevelhebber der Zeestrijdkrachten" was dropped and the position of "Commander of the Naval Force in The Netherlands" was upgraded to the current CZsk position. Ever since the integration of the Royal Netherlands Marine Corps into the Navy, the former Commander of the Marine Corps has held the position of Deputy Commander of the Royal Netherlands Navy. 
In addition to being the commanding officer of the Dutch Navy, under the terms of the BENESAM Treaty the CZsk is also the Admiral of the Benelux (the commanding officer of the integrated command of the Dutch and Belgian fleets). This means the CZsk is the commanding officer of the operational units of the Royal Netherlands Navy and the Belgian Naval Component.
Also, the CZsk shares command responsibility with the Chief of the Netherlands Defence Staff for units that have been deployed on international missions (under the colors of the United Nations).
The position of CZsk is statutorily held by a Vice Admiral or Lieutenant General of the Marines (NATO OF-8). The current CZsk is Vice-admiraal Rob Kramer, who succeeded Lieutenant general Rob Verkerk in the position in September 2017.
