(NEWSMAX) Germany has offered Warsaw the Patriot missile defense system to help it to secure its airspace after a stray missile crashed in Poland last week, Defence Minister Christine Lambrecht told a newspaper on Sunday.

The German government had already said it would offer its neighbor further help in air policing with German Eurofighters after the incident, which initially raised fears that the war in Ukraine could spill across the border.

“We have offered Poland support in securing airspace – with our Eurofighters and with Patriot air defense systems,” Lambrecht told the Rheinische Post and General Anzeiger.

The missile that hit Poland last week, killing two people, appeared to have been fired by Ukraine’s air defenses rather than a Russian strike, NATO chief Jens Stoltenberg has said.

Ground-based air defense systems such as Raytheon’s Patriot are built to intercept incoming missiles.

NATO has moved to strengthen air defenses in eastern Europe since Russia’s invasion of Ukraine in February. More than a dozen NATO allies led by Germany in October kicked off an initiative to jointly procure air defense systems for several layers of threats, including Patriot.

Germany had 36 Patriot units when it was NATO’s frontline state during the Cold War.
