German munitions production is rising rapidly, but the limit has not yet been reached, Defence Minister Boris Pistorius said on Monday while on a visit to a company that manufactures detonators and explosives, reported dpa. Pistorius was speaking at the production site of Dynitec in Troisdorf to the north of Bonn. The company is a subsidiary of Diehl Defence, which makes missiles and ammunition. He described the company as an example of how Germany should become less dependent, "wherever possible through technological development and also through expanding industrial production sites and capacities in Germany." The government in Berlin wants to boost arms production amid Russia's war in Ukraine and US President Donald Trump's "America First" policy. Diehl Defence chief executive Helmut Rauch said capacity had been doubled at the Troisdorf plant and would be doubled again next year. Diehl Defence is investing billions of euros in German factories, he said. He pointed to the IRIS-T air defence system, where capacity had been increased tenfold. Rauch said that eight IRIS-T units had been supplied to Ukraine and that a further eight would follow. He described the system, which is for short-range use, as the most modern air defence system in Ukraine that had demonstrated great effectiveness. "The success rate approaches close to 100%," Rauch said. Aims by the local authority to build housing on the Troisdorf production site almost prevented its expansion.
