Rheinmetall Waffe Munition GmbH is a German Rheinmetall Group manufacturer based in Unterluss and focused on weapon systems, ammunition, pyrotechnics, and protection systems.

Rheinmetall Waffe Munition GmbH was created in 2004 through the step-by-step merger of Rheinmetall W&M GmbH, Mauser-Werke Oberndorf Waffensysteme GmbH, BUCK Neue Technologien GmbH, Pyrotechnik Silberhuette GmbH, and NICO-Pyrotechnik Hanns-Jurgen Diederichs GmbH & Co. KG. Rheinmetall says the merger brought an important part of its weapon and munitions activities under centralized management.

The company's German footprint is spread across Unterluss, Berlin, Dusseldorf, Neuenburg, Oberndorf, Silberhutte, Trittau, and Schneizlreuth/Fronau, with an additional RWM presence in Rijswijk in the Netherlands. Rheinmetall's location listing places the Unterluss address at Heinrich-Ehrhardt-Strasse 2, while the company page describes Unterluss as the headquarters.

For the catalog, Rheinmetall Waffe Munition GmbH is most visible through Rheinmetall-linked ammunition and naval weapon entries. SMArt 155 connects the profile to German sensor-fuzed 155 mm artillery ammunition through the GIWS Diehl-Rheinmetall joint venture, while Marineleichtgeschutz 27 mm connects it to the Mauser/Oberndorf and Rheinmetall naval-gun line built around the BK-27M revolver cannon.
