Defending a common Nordic air space may be the solution to keeping military costs down in Sweden. The Supreme Commander of the Swedish Armed Forces, Sverker Göranson, suggested this measure when the annual Society and Defence conference got underway in Sälen Sunday.

A common Nordic air space would mean that Finland and Norway would be responsible for Sweden’s national security, and vice versa. It is possible that Denmark would also participate, according to newspaper Dagens Nyheter.

“We have flown together in military efforts and training, we have a common technical system. So, we have to review the legal conditions and see how far we’re prepared to go in letting go control of the national defense,” says Göranson, adding, “There’s a potential to save money here.”

As many European countries plan to make big cuts into their military spending, Sweden’s own armed forces have been coalescing more and more with the defense structures of neighboring countries, the European Union and NATO.
