Germany has agreed to deliver anti-aircraft tanks to Ukraine, the German Defense Ministry announced on Tuesday, a move that underscores a major shift in its approach to providing military help to Ukraine.

The commitment to deliver the Gepard anti-aircraft systems was announced by defense minister Christine Lambrecht during a meeting of international defense officials at the Ramstein US Air Force base in Germany on Tuesday.

“We decided yesterday that we will support Ukraine with anti-aircraft systems … which is exactly what Ukraine needs now to secure the airspace from the ground,” Lambrecht said during the meeting at the base.

This is significant as it is the first time Germany has agreed to provide this type of heavy weaponry to Ukraine as it fights off the Russian invasion. The Gepard systems were phased out from active duty in Germany in 2010.

Germany initially resisted calls to provide weaponry to Kyiv, agreeing only to provide humanitarian help and medical equipment. That approach was in line with Germany’s decades-long policy of not supplying lethal weapons to crisis zone.

Just months before Russian President Vladimir Putin order the invasion into Ukraine, the then new German government agreed to include the restrictive arms export policy into its coalition agreement.

But facing pressure from allies and the German public, the government was forced to overhaul the rules. By late February, German Chancellor Olaf Scholz announced Germany would start delivering some weapons to Ukraine, although at that point he insisted on calling them “defensive.”

He also announced Germany would start pumping more money into its own armed forces.

First such investment was publicly confirmed last month when Germany announced it would buy 35 US-made F-35A fighter jets.
