Opel automobile production ended in October 1940, after the company's American leadership had rejected an "invitation" to switch to munitions manufacture a few months earlier. In 1942 Opel switched to wartime production, making aircraft parts and tanks. They kept manufacturing trucks at the Brandenburg plant, where the 3.6-liter Opel Blitz truck had been built since 1938. These trucks were also built under license by Daimler-Benz in Mannheim.
