Rheinmetall began in 1889 under Heinrich Ehrhardt as a Ruhr-area metals and munitions works. It grew with German rearmament before 1914 and again in the 1930s -- a firm file that includes the Nazi-era armaments economy and the 1945 collapse. This page will not turn those years into a production lesson. It will name them as dated industrial history beside Krupp and other Ruhr names.
The postwar legal and political break matters: West German rearmament from 1955-56 (Bundeswehr, NATO) brought the firm back as a land-systems supplier -- guns, then vehicles, then electronics. The Rh-120 smoothbore is the English hobby-and-staff-college name; Leopard 2 is the vehicle everyone photographs. Armin Papperger is the late public CEO of the 2010s-20s export and "Zeitenwende" years after Russia's 2022 full-scale invasion of Ukraine recast German defence budgets.
Korean readers should treat this page as a partner-and-rival file to Hanwha: K2 powerpack and gun stories, K9 European production talk, and a European land-systems market that suddenly wanted volume. Intensity is low. Duration is long. No calibre, charge, or armour-layout content belongs here.
Frequently asked questions
When was Rheinmetall founded?
1889, associated with Heinrich Ehrhardt, in the Dusseldorf / Ruhr industrial world.
Did the firm close in 1945?
Defeat ended the Nazi-era armaments economy. The defence revival is a 1950s West German rearmament story, not a seamless shop.
What is the Rh-120 in this file?
A public designation of a late Cold War tank gun associated with the firm and with Leopard 2. Named as history. Not a specification or a build guide.
How does Korea fit?
Industrial partnerships and competitions around K2 and K9 -- a 2010s-20s firm story. See Hanwha and the ROK military pages.
What is Zeitenwende here?
A 2022 German political slogan after Russia's full-scale invasion of Ukraine, used in budget and plant-expansion news. A late chapter, not a weekly tracker.
Why mention forced labour?
Because a Ruhr armaments firm in 1939-45 shares that ledger with peers. Skipping it is a brochure.
Is this a Krupp page?
No. Krupp is a cousin name in the same industrial world. This file is Rheinmetall's letterhead.
Is this a how-to?
No. No gun, vehicle, or ammunition manufacturing or employment content.
