"This activity has been coordinated with the Kingdom of Denmark, and all supporting forces operate with the requisite diplomatic clearances. The Government of Greenland is also informed of planned activities," NORAD said.
"NORAD routinely conducts sustained, dispersed operations in the defense of North America, through one or all three NORAD regions (Alaska, Canada, and the continental U.S.)," the command added.
Trump has said in recent weeks that the U.S. needs Greenland for national security reasons. The president claims that if the U.S. does not step in, China or Russia could use the Arctic territory to their advantage.
"NATO has been telling Denmark, for 20 years, that ‘you have to get the Russian threat away from Greenland.’ Unfortunately, Denmark has been unable to do anything about it. Now it is time, and it will be done!!!" Trump said in a Truth Social post on Monday.

Despite the objections from allies, Trump administration officials have continued to argue that U.S. control of Greenland is necessary to protect national security interests in the Arctic.
On Saturday, Trump said the U.S. would impose 10% tariffs on multiple European countries unless Denmark agreed to the "complete and total purchase of Greenland," warning that global security and U.S. national defense were at stake.
The president said that starting on Feb. 1, Denmark, Norway, Sweden, France, Germany, the U.K., the Netherlands and Finland would be subjected to a 10% tariff. The tariff would then increase to 25% on June 1 and "will be due and payable until such time as a deal is reached for the complete and total purchase of Greenland," Trump wrote on Truth Social.
While addressing the World Economic Forum in Davos, Switzerland, European Commission President Ursula von der Leyen called the tariff threat "a mistake, especially between long-standing allies," according to The Associated Press.
