The Finnish Defence Forces and NATO


Finland became a NATO member state on April 4th, 2023. As a NATO member, Finland is a part of alliance's common defence. A NATO membership does not diminish the need for a strong own defence. Finland's military defence remains the core task of the Defence Forces, and Finland continues to decide on the principles for the implementation of military national defence itself.

The Finnish Defence Forces prepare for possible threats to Finland in cooperation with other authorities, and our ability to defend Finland against military violence is also good. The preventive capability is formed by adequate military capability, the desire to defend the country and the ability of society to support the implementation of the defense with all resources. Military ally strengthens Finland's national defence capability.
