Naval Staff (Swedish: Marinstaben, MS) is the staff of the Chief of the Swedish Navy. Established in 1907, it originated from the Fleet Staff which was established in 1896. The Naval Staff's duties included, among other things to assist the Chief of the Navy with leadership of the Navy's mobilization, training, tactics, organization, equipment and personnel to the extent that such activity was not directly related to operational activities, which was handled by the Defence Staff. In 1994, the Swedish Armed Forces Headquarters took over the Naval Staff's duties. The Naval Staff was reestablished in 2019.
