Although no Danish combat aircraft are usually based  in Greenland,  the Flyvevåbnet's F-16 fighters have, in the past flown non-stop from a base in Greenland  (Søndre Strømfjord) to Ålborg, their home base in Denmark. Obviously,  if  ever required to back up Danish claims, the F-16s – or armed helicopters - could reinforce Greenland.
