The Standing NATO Maritime Groups are a multinational, integrated maritime force made up of vessels from various allied countries. These vessels (including their helicopters) are permanently available to NATO to perform different tasks ranging from participating in exercises to actually intervening in operational missions. These groups provide NATO with a continuous maritime capability for operations and other activities in peacetime and in periods of crisis and conflict. They also help to establish Alliance presence, demonstrate solidarity, conduct routine diplomatic visits to different countries, support transformation and provide a variety of maritime military capabilities to ongoing missions.
NATO has two Immediate Reaction Forces: the Standing NATO Maritime Groups composed of the SNMG1 and the SNMG2; and the Standing NATO Maritime Mine Countermeasure Groups (SNMCMG1 and SNMCMG2).
