Background
Since the beginning of the 21st century, the Arctic's strategic importance has grown significantly, as sea ice has been reduced and maritime routes became accessible, enabling easier approach to natural resources. Since around 2007, the Putin regime has been pursuing an aggressive foreign policy against the Western world and NATO.
The new climate in the region brought expanded military and economic activity by both Arctic and non-Arctic nations, mainly China and Russia. In recent years Russia significantly increased is military infrastructure in the Arctic, by reopening, reinforcing and modernizing some bases along the northern coastline, while increasing air and naval patrols. Meanwhile, China that stated that it is a "near Arctic state", has also increased its scientific, commercial, and logistical operations in the area.
After Finland and Sweden joined NATO, seven of the eight Arctic countries became members of the alliance. This has given NATO a stronger and more direct role in Arctic security. Because of this, NATO has launched Arctic Sentry as part of its wider efforts to strengthen shared defense and deterrence in Northern Europe.
Objectives NATO Arctic Sentry's designated mission is to increase NATO’s presence in the region, by enhancing intelligence, surveillance, and reconnaissance activities. The aim is to strengthen NATO’s offensive and defensive capabilities while improving coordination between the allied forces, operating in Arctic and sub-Arctic conditions. The mission also supports and connects existing national and multinational exercises in the region while helping to protect critical infrastructure and important sea routes. Arctic Sentry operates across several areas, including air, sea, land, cyber, and space.
One focus is the GIUK gap between Greenland, Iceland, and the United Kingdom as a route from the Arctic Ocean to the North Atlantic, which is also used by submarines of the Russian Navy.

This will include maritime patrols and naval deployments, air policing and long range reconnaissance missions, and military exercises focused on Arctic conditions.
