Sweden has, like most European countries, invested heavily in defence following Russia's invasion of Ukraine. However, Sweden's vast territory has remained vulnerable to aerial threats.
"The experience from the war in Ukraine clearly shows how crucial a robust and resilient air defence is," Defence Minister Pal Jonson told reporters at a security conference in northern Sweden.
He said Sweden would buy short-range air defence systems to protect cities, bridges, power plants and other critical infrastructure.
On Sunday Prime Minister Ulf Kristersson criticized the U.S. administration's "threatening rhetoric" against Greenland and Denmark, saying the U.S. should thank Denmark for being a loyal ally.
