Denmark has announced $4.2 billion (£3.2 billion) of extra defence spending to boost security in the Arctic and North Atlantic regions, including Greenland.

It will also spend $4.5 billion buying 16 more F-35 fighter jets from the US, bringing its total fleet of such advanced planes to 43.

With this... agreement we significantly strengthen the capabilities of the Danish Armed Forces in the region, Denmark's Defence Minister Troels Lund Poulsen said in a statement on Friday.

The Arctic is at a critical crossroads between North America, Russia and the rest of Europe. The statement by the Danish defence ministry states that the purpose of its military is security, and if necessary, defence in the NATO security alliance.

The task of the Armed Forces is to ensure security throughout the Kingdom - and, if necessary, to defend Greenland, the Faroe Islands and Denmark within the framework of NATO in all domains, the Chief of Defence, Michael Hyldgaard, told Danish public broadcaster DR, without specifying potential adversaries.

Denmark worked on the new defence package with the governments of Greenland and the Faroe Islands.

It will buy two new Arctic ships, maritime patrol planes, drones, and early warning radar.

Crucially, a new Arctic command headquarters will be established in the Greenlandic capital, Nuuk, along with a new military unit under Joint Arctic Command in Greenland.

In addition, an undersea cable connecting Greenland and Denmark will be funded.

Greenland is critically located between North America and Russia, and while it enjoys significant autonomy, it remains part of the kingdom of Denmark. The island has drawn increased interest due to its natural resources, including rare earth minerals, uranium, and iron.

Greenland also serves as a strategic military location, facilitating US military operations and surveillance in the region.

The region's geopolitical importance has been highlighted by past comments from US political figures, notably former President Donald Trump, regarding Greenland's strategic value in military and economic terms. Greenland’s leadership has insisted, however, that the island is not for sale.
