Diehl has expanded Germany’s artillery ammunition manufacturing capacity with a new production line dedicated to 155mm shell bodies, supporting supplies to the Bundeswehr and allied militaries. Diehl Metall and Diehl Defence officially opened the facility in Röthenbach an der Pegnitz on November 10. The project began in June 2024 in partnership with Norway’s Nammo and involved converting a 7,000-square-meter (75,347-square-foot) factory hall and installing new machinery, including two forging presses. The plant will manufacture metal shell bodies for the DiNa 155mm artillery round, with Diehl Metall responsible for production and Diehl Defence handling quality assurance and integration before the components are incorporated into complete ammunition. Nammo, which developed the DiNa round, is providing the technology and manufacturing expertise. The investment is part of Diehl Defence’s broader effort to increase German production capacity as demand for military equipment and ammunition rises. The company has restarted defense-related manufacturing at Spreewerk Lübben in Brandenburg, where production of ammunition components and fuzes is planned alongside the creation of around 150 jobs by 2027. The expansion also follows a major 2024 contract awarded to the Diehl-Nammo consortium by Germany’s Federal Office of Bundeswehr Equipment, Information Technology and In-Service Support. Other investments include a missile integration centre at Nonnweiler, which opened in January.
