Diehl has established a new production line in Germany for 155mm artillery shell bodies, expanding its capacity to supply ammunition to the Bundeswehr and allied forces.
Diehl Metall and Diehl Defence inaugurated the facility in Röthenbach an der Pegnitz on November 10, following a project launched in June 2024 with Norway’s Nammo.
The companies converted an existing 7,000-square-meter (75,347-square-foot) factory hall and installed new equipment, including two forging presses.
The facility will manufacture the metal shell bodies for the DiNa 155mm artillery round. Diehl Metall will produce the bodies, while Diehl Defence will oversee quality and integration requirements before incorporating them into finished ammunition.
Nammo, which developed the DiNa round, is contributing technology and production expertise to the project.
“Delivering the defence capabilities needed for Europe requires a strong defence industrial base and close cooperation across industry,” Nammo AS CEO Morten Brandtzæg said.
Diehl’s Production Expansion
The Röthenbach facility is part of Diehl Defence’s broader production expansion in Germany as demand for military equipment and ammunition grows.
The company has resumed defense-related production at Spreewerk Lübben in Brandenburg. The site is being developed to manufacture ammunition components and fuzes, with plans to create around 150 jobs by 2027.
The latest expansion follows a major 2024 order awarded to the Diehl-Nammo consortium by Germany’s Federal Office of Bundeswehr Equipment, Information Technology and In-Service Support.
Diehl has also invested in other production facilities, including a new missile integration center at Nonnweiler, which opened in January.
