Did you know2023
Rheinmetall's Automotive division makes the engine pistons for internal combustion vehicles -- the precision-machined aluminum components that convert combustion into motion in BMW, Mercedes, and Volkswagen engines. Its Defence division makes 155mm artillery shells, which are precision-machined steel cylinders that also convert propellant combustion into motion (of projectiles). The manufacturing physics overlap: both require high-precision metal machining, dimensional tolerances in the micron range, and metallurgical quality control. As automotive ICE production declines with EV transition, Rheinmetall's piston revenue will fall; as NATO defense spending rises post-Ukraine, its artillery shell revenue will grow. The company is literally in the process of replacing civilian combustion products with military combustion products, using the same German precision manufacturing base, as the energy transition and European rearmament intersect in a single Düsseldorf manufacturer.
Rheinmetall AG ↗Origin2023
Rheinmetall was founded in 1889 in Düsseldorf as Rheinische Metallwaaren- und Maschinenfabrik, initially making metalware and later precision machined parts. The company pivoted to military hardware in the 1890s-1900s and became a major WWI and WWII artillery shell and weapons manufacturer. After WWII, the Allied Control Authority banned Rheinmetall from military production, and the company pivoted to automotive pistons and engine components -- the same precision metal machining technology applicable to both shells and pistons allowed this transition. The automotive division (originally Rheinmetall Borsig, later Kolbenschmidt) sustained the company through 40 years of West German rearmament restrictions. When Germany rearmed within NATO, Rheinmetall re-entered defense and rebuilt its military hardware expertise. Today Rheinmetall is expanding 155mm artillery shell production from 70,000 to 700,000 rounds per year for the Ukraine war effort -- a German company's Cold War automotive survival strategy is now the production capacity expansion platform for European defense.
Rheinmetall AG ↗Capacity2025
Rheinmetall is scaling its group-wide propellant powder production from 5,000 tonnes/year (2022) to 12,000 tonnes/year (2027). To secure nitrocellulose supply, Rheinmetall acquired Hagedorn-NC GmbH (German nitrocellulose producer) in April 2025. The company aims to manufacture 1.1 million 155mm artillery shells annually by 2027. This represents the largest peacetime expansion of Western European propellant capacity in three decades.
