Founding and early growth In April 1889, a conglomerate, the Hörder Bergwerks-und Hütten-Verein founded the Rheinische Metallwaren- und Maschinenfabrik Aktiengesellschaft to produce ammunition for the armed forces of the
German Empire. The first Rheinmetall factory was established by engineer
Heinrich Ehrhardt (1840–1928) in
Düsseldorf. In 1896, Rheinmetall presented the world's first rapid-fire gun suitable for field service, with variable recoil and combined barrel recoil and a forward feed device. It was based on patents by the engineer Konrad Haußner. The Prussian artillery testing commission rejected it, either misjudging or not realising the possibilities. After the successful introduction of recoil-operated guns by France (Canon de 75 mle 1897), this attitude changed and the development became a great economic success for Rheinmetall. In 1901, on the initiative of Heinrich Ehrhardt, Rheinmetall took over the bankrupt Munitions- und Waffenfabrik AG in
Sömmerda, expanding its product range.
World War I and the interwar period In the following years, Rheinmetall also grew due to orders from abroad. In 1906, the factory in Düsseldorf was expanded. At the beginning of the
First World War in 1914, Rheinmetall was one of the largest armaments manufacturers in the German Empire, and employed almost 8,000 people. By the end of the war, the workforce had increased to almost 48,000 workers and employees, including around 9,000 women. The built-up area at the main plant quadrupled during this time. After the war, the armaments production came to a standstill and Rheinmetall had to lay off employees. The provisions of the
Treaty of Versailles made it necessary to switch to civilian products. Rheinmetall therefore produced locomotives, railway carriages, agricultural machinery and steam ploughs in the Rhineland. The factory in Sömmerda produced precision mechanical devices such as typewriters and calculating machines. Steel production in Rath was increased to ensure the production of civilian goods. From 1921, Allied regulations once again permitted the production of weapons systems in small quantities. The plant in Düsseldorf-Derendorf was occupied by Belgian and French troops in 1921, during the Allied occupation of the Rhineland, and from 1923 to 1925 during the occupation of the Ruhr, and was partially devastated. Due to a lack of orders, civilian production had to be discontinued except for the manufacture of steam ploughs. In 1925, the state holding company VIAG of the German Reich bought a majority stake in Rheinmetall, as part of a capital increase. In April 1933, Rheinmetall bought the locomotive manufacturer Borsig, which was about to be liquidated, and thus came into possession of a large factory in Berlin-Tegel. This led to Rheinmetall being renamed Rheinmetall-Borsig AG in 1936. As part of the rearmament of the Wehrmacht, Rheinmetall increasingly developed and produced weapons and ammunition on behalf of the Reich Ministry of War from the mid-1930s onward. The products ranged from machine guns and cannons, anti-tank guns, mine launchers and field guns to anti-aircraft guns and railway guns. In 1937, the subsidiary
Alkett (Altmärkische Kettenwerke) was founded in Berlin for the development and construction of armoured tracked vehicles. From 1937 onward, it was the second largest German armaments company. In 1938, the company moved its headquarters from Düsseldorf to Berlin.
World War II During the
Second World War, armaments production was increased to the maximum and the development of new weapons systems was demanded. State influence through
Wehrmacht institutions and the integration of Rheinmetall-Borsig into the state-owned company
Reichswerke Hermann Göring increased to such an extent that the company came under complete state control and was integrated into the planned war preparations. The company manufactured weapons for the German armed forces that included large quantities of the AA
3.7 cm Flak 43 gun and to a lesser extent, the
5 cm Flak 41. Other weapons produced included machine guns such as the
MG 131 machine gun. In the last two years of the war, the production facilities were severely damaged or destroyed by
Allied air raids. After a heavy air raid on the factories in Düsseldorf, numerous production areas were relocated east to areas of the later
GDR, such as
Apolda and present-day Poland, such as
Guben and
Breslau. During the war, the number of employees grew to 85,000. By the end of the war, most of the Rheinmetall-Borsig plants had been destroyed. The plants in Düsseldorf, West Berlin and Unterlüß came under the control of the Western Allies, and under trusteeship. All properties in the territories occupied by the Red Army were expropriated. Some factories were completely dismantled by the victorious powers. During the Second World War, numerous
forced labourers worked in the Rheinmetall factories. In the Unterlüß plant alone, around 5,000 foreign forced labourers and
prisoners of war, approximately 2,500 Poles, 1,000 from the USSR, 500 Yugoslavs, 1,000 from other countries, were liberated by British troops at the end of the war. Between 1944 and 1945, Rheinmetall-Borsig took over the sponsorship of the nursery for foreign children in Unterlüß, which was also a maternity home for forced labourers and a killing centre for their children. At times, Hungarian Jewish women from a subcamp of the
Bergen-Belsen concentration camp were deployed in Unterlüß.

Rheinmetall Rh-120 tank gun The Düsseldorf plant was not fully destroyed after the Second World War. While production ceased, a small number of employees and workers apparently remained in service, carrying out clean-up work and small-scale civilian production. The Rheinmetall sites were not severely affected by dismantling following their capture by the Western Allies and the Soviet forces. In the
East Germany, state-owned spinoffs of Rheinmetall manufactured office machines (including
typewriters, automotive parts and moped engines, cameras, and later printers and personal computers. Much of the production took place at
Sömmerda. In the following years, the company's civilian division was reorganised and strengthened in 1981 with the purchasing of multiple companies, although the company was unsuccessful in acquiring the
WMF Group. In 1999, Rheinmetall sold off its packaging technology division to IWKA AG. In 1986, the Automotive Technology division was established through the acquisition of carburettor manufacturer Pierburg GmbH. Together with Diehl Munitionssysteme, Rheinmetall founded the Gesellschaft für Intelligente Wirksysteme (GIWS). GIWS specialised in intelligent ammunition, projectiles and other defence technology systems. In 1989, due to the changed global political situation at the end of the
Cold War, Rheinmetall diversified into civilian industrial products.
1990s By acquiring a 100 per cent stake in MaK System Gesellschaft, part of Friedrich Krupp AG, between 1990 and 1992, Rheinmetall expanded its expertise in the field of new systems for land forces and special vehicles. For example, for use in environmental protection. In the same year, Rheinmetall delivered the first
Wiesel armoured weapon carrier to the German armed forces. The company strengthened its involvement in the field of ammunition production by acquiring a stake in WNC-Nitrochemie GmbH in Aschau am Inn. In 1993, Rheinmetall expanded its civilian product range by acquiring Mauser Waldeck AG to build up the Office Systems division, taking over Heimann Systems GmbH to strengthen the Security Technology division and acquiring a majority stake in Preh-Werke to expand the Automotive Technology division. In 1995, Rheinmetall expanded its expertise in medium-calibre automatic cannon systems, by acquiring a majority stake in Mauser-Werke Oberndorf Waffensysteme GmbH and increasing Pierburg's involvement in the USA. In the same year, Rheinmetall acquired a stake in STN Atlas Elektronik in order to strengthen its expertise in defence electronics. In 1997, Rheinmetall underwent a fundamental reorganisation, in the form of mergers and new acquisitions, including acquiring Hirschmann, an electronics communication company. In 1998, the first unit of the new gun artillery system
Panzerhaubitze 2000, developed by Rheinmetall and MaK Systemgesellschaft, was handed over to the Bundeswehr, and the Rhino minesweeper from MaK Systemgesellschaft was deployed in the former Yugoslavia. Rheinmetall took over the defence technology of BUCK System GmbH and formed BUCK Neue Technologien. In 1999, Rheinmetall acquired a majority stake in Oerlikon Contraves, a supplier of combined cannon and guided missile systems for air defence, and Eurometaal Holding N.V., a manufacturer of medium calibre artillery. In late 1999, Rheinmetall took over the companies KUKA Wehrtechnik and Henschel Wehrtechnik, and later combined the two with MaK Systemgesellschaft, to form the new company, Rheinmetall Landsysteme.
2000 and onward In 2000, Rheinmetall's Executive Board decided to concentrate on defence technology, automotive technology and electronics. Subsequently, it sold off multiple subsidiaries. By 2004, the focus on the defence technology divisions was largely completed. In 2003, Rheinmetall Landsysteme delivered the first new
Marder 1A5 mine-protected infantry fighting vehicle. To develop the new
Puma infantry fighting vehicle for the Bundeswehr, Rheinmetall Landsysteme and Krauss-Maffei Wegmann set up the joint venture PSM GmbH, in which both companies hold a 50 per cent stake. In the Defence Technology division, Rheinmetall W&M GmbH was merged with Mauser-Werke Oberndorf Waffensysteme GmbH, Buck Neue Technologien GmbH and Pyrotechnik Silberhütte GmbH to form the new Rheinmetall Waffe Munition GmbH. Rheinmetall cooperated with Rafael Ltd. and Diehl Munitionssysteme GmbH for missile manufacturing contracts. In 2005, Rheinmetall Landsysteme became a co-partner in the newly founded Heeresinstandsetzungslogistik (HIL). The company is responsible for the maintenance of selected vehicles and weapon systems of the German Army. In May 2010, Rheinmetall and MAN founded the joint company Rheinmetall MAN Military Vehicles (RMMV). This created a full-range supplier in the market for wheeled military vehicles, covering the complete range of protected and unprotected transport, command and functional vehicles for international armed forces. Rheinmetall holds a 51 per cent stake in the company and MAN 49 per cent. Between 2010 and 2011, Rheinmetall acquired the German activities of Verseidag Ballistic Protection. In February 2011, Rheinmetall increased its stake in ADS Gesellschaft für aktive Schutzsysteme. In 2012,
KSPG took over the plain bearing manufacturing activities of Kirloskar Oil Engines Ltd (KOEL) in
Pune,
India. In January 2012, Rheinmetall and Cassidian combined their activities in the field of unmanned aerial systems and cargo loading systems in a joint venture. Cassidian holds 51 percent and Rheinmetall 49 percent of the shares in the newly founded Rheinmetall Airborne Systems GmbH. In 2019 the
Rheinmetall BAE Systems Land joint venture was formed to manufacture Boxer and Challenger 3 vehicles for the
British Army.
Post 2022 gun system Following the
Russian invasion of Ukraine in 2022, German Chancellor
Olaf Scholz gave the
Zeitenwende speech during a special session of the
Bundestag in February allocating a special fund for the Bundeswehr of 100 billion euros for increased defence spending. Rheinmetall Group CEO Armin Papperger expressed the expectation that Rheinmetall would benefit from this on a large scale by placed orders and an increased share price. In June 2022, Rheinmetall presented its latest
KF51 Panther main battle tank at the
Eurosatory arms fair. In November 2022, Rheinmetall announced the purchase of Spanish ammunition manufacturer
Expal, which was completed in August 2023 for 1.2 billion euros, although the process was subject to a competition investigation. As a result, Rheinmetall was fined 13 million euros in 2024 for providing misleading information regarding its merger with Expal Systems. In December 2022 and into early 2023, Rheinmetall increased production of ammunition in Germany, in connection with the war in Ukraine and a Swiss veto on ammunition deliveries. Rheinmetall announced that it was building a new production facility for 20-35 millimeter calibre ammunition. In July 2023, the plant started production. Also in 2023, Rheinmetall opened a service and logistics centre in
Satu Mare,
Romania for maintaining the weapons used by Ukraine. A year later, Rheinmetall confirmed that the facility was operating and that it was developed in cooperation with the
Automecanica Mediaș company. The same year, Automecanica Mediaș was renamed to Rheinmetall Automecanica after the German company purchased its majority stake. In October 2023, Ukrainian Prime Minister
Denys Shmyhal presented Chancellor Scholz with the certificate of registration of the joint venture Rheinmetall Ukrainian Defence Industry LLC, based in Kyiv, which began operations in the same month. Rheinmetall began producing the
Lynx Infantry Fighting Vehicle in Ukraine in mid 2024, with the first units expected to be delivered by the end of the year. Production of the
TPz Fuchs Armoured Personnel Carrier in Ukraine was also planned on a similar timescale, though it is unclear if this has also begun. In 2023 and early 2024, an Indian
public-owned company,
Munitions India, exported 500 tonnes of explosives to Germany's Rheinmetall. An initial shipment of 144 tonnes of explosive was sent in October 2023. Two additional shipments were undertaken with the final shipment in March 2024. In 2024, it was reported 200,000 artillery shells were to be manufactured at a new plant in
Unterlüß. In 2024, Rheinmetall signed a deal with
Lithuania to build a
155 mm artillery ammunition plant. The company will invest around €180 million and the plant will be jointly owned by Rheinmetall and the Lithuanian government. The plant is being built in
Baisogala and is expected to be operational in mid-2026. In September 2025 a similar 155 mm ammunition plant was announced to be built by Rheinmetall in
Latvia. In July 2024, US intelligence services claimed to have foiled a Russian plot to assassinate Armin Papperger (CEO and chairman of the executive board). In May 2025, the Indian
Reliance Group agreed to provide Rheinmetall with explosives and ammunition. The deal included the supply of raw materials as well as the production of munitions at a facility in India. The businesses also announced a strategic partnership to work on several joint areas of business. Rheinmetall Waffe Munition GmbH placed an export order worth from Reliance Defence. The contract is a part of the larger strategic partnership with the same company. In September 2025, the company acquired the ship producer and shipyards of
Blohm+Voss. They also agreed to establish
joint production of
155 MM artillery in Ukraine. == Divisions ==
