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.

Deep introduction
A Ruhr works that outlived two German armies
Rheinmetall is a continuity of place and metal with a political discontinuity in 1945 -- then a NATO supplier, then a 2020s headline.
1889-1945
Ehrhardt's works, the First World War munitions economy, Weimar contraction, and Nazi-era expansion are one long Ruhr sentence. Forced labour in the second war is part of the ledger, as with other German armaments firms.
No recipe from those factories will be copied here.
1956-90
Bundeswehr rearmament and Leopard generations made a democratic-German contractor. Franz Josef Strauss-era politics sit in the background of that return.
The tank page holds type history; this page holds the firm.
1990-2021
Post-Cold War shrink, then export hunts, then electronics and vehicle packages. Partnerships with other European firms and with ROK industry begin as footnotes and thicken.
K2/K9 sentences belong also on the Hanwha page.
After 2022
Zeitenwende speeches and plant-expansion headlines are a late political chapter -- recorded as budget history, not as a current order book to update weekly.
The European works that the tank type and the Hanwha export story both keep running into.

Key terms
Heinrich Ehrhardt
1889 founder name.
Rh-120
Late Cold War tank-gun designation in English hobby speech -- named, not specified as a build.
Bundeswehr return
1955-56 West German rearmament that legally restarted a defence contractor.
Zeitenwende
2022 German political slogan for a budget turn -- a late caption.
K2 / K9 talk
ROK types in European industrial negotiations -- firm history.
Forced labour ledger
Nazi-era cost that a firm page must not skip.
Continuity and break
The same Ruhr place; a different German state after 1949/55.
Duration is high because the place is old; politics are not a straight line.
Partner to Korea
Guns, vehicles, and ammunition-plant headlines with Hanwha are a two-firm story.
Neither page is a joint-venture manual.
Hobby vs archive
Leopard posters outrun the 1944 labour file. This atlas will not let them.
Keep Hobby vs archive pinned to 1979-80s (Leopard 2 / Rh-120 public era): The poster types. Rheinmetall remains a 1889-present as a firm (defence revival after 1956 Bundeswehr rearmament) file in Dusseldorf and Ruhr works; Bundeswehr procurement; later European and Korean partnerships, not a playbook.

Frequently asked questions
Are the scores a ranking of nations or armies?
No. Scores are browsing aids inside an era-bounded atlas — not live league tables of countries.
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.
