Rheinmetall's Kassel Blueprint: From Locomotive Halls to Europe's Tank Capital
Published on 08/29/2026 at 21:01 | Editorial boerse-global.de
The industrial landscape of northern Hesse is being redrawn at a pace that Germany's defense sector has rarely witnessed. Rheinmetall is pushing ahead on multiple fronts in Kassel — from a potential takeover of Alstom's locomotive plant to a clandestine mega-project that would turn the city into the heart of European armored vehicle production. Yet for all the factory-floor ambition, the company's share price tells a more cautious story.
A City Transformed
The numbers behind the Kassel expansion are staggering. Under the codename "Arminius," Rheinmetall is reportedly planning to expand its tank production so dramatically that the site would become Europe's largest armored vehicle factory. The driving force: potential Bundeswehr orders for the Boxer wheeled armored vehicle worth up to €40 billion, which could keep the plant busy through 2040.
The first tranche alone is substantial — €12.4 billion for more than 1,500 Boxer vehicles, with a possible framework agreement of €14 billion to €26 billion covering over 5,000 units. The workforce at the site is slated to grow from 2,200 employees today to 3,000 by the end of 2028 — a remarkable trajectory given that the facility employed just 1,000 people in 2022. Annual production could reach 500 Boxers, with plant revenue climbing from €1.5 billion to roughly €5 billion.
The Alstom Question
In parallel, Rheinmetall is in talks to acquire Alstom's Kassel locomotive works, a move that CEO Armin Papperger confirmed during a recent appearance. A meeting with Alstom's chief executive is scheduled within the next four weeks, and the future of the site's 900 employees hangs in the balance. Papperger has indicated that taking on the workforce is a possibility.
The negotiations are a second attempt — initial discussions in June ended without a resolution, but talks have since resumed. Alstom expects clarity within weeks. Not everyone is waiting patiently: the works council and IG Metall have already announced protest actions, with employees worried about a transformation from locomotive manufacturing to arms production.
Should investors sell immediately? Or is it worth buying Rheinmetall?
Building the Defense Hub
The Alstom talks sit alongside an already-announced investment in the region. Rheinmetall's "Defence Hub Nordhessen" at Kassel Airport — a logistics and training center spanning 30,000 square meters with a drone testing facility — carries a price tag exceeding €260 million, supported by the state of Hesse with a double-digit million-euro subsidy.
The airport itself has become a point of political friction. The Greens have criticized annual subsidies of €20 million for Kassel-Calden airport, the Left party warns of militarization, and the "Kassel Airport stoppen" alliance is mobilizing against the plans. Local politicians and business leaders, by contrast, largely back the expansion.
The Order Book Backbone
These investments aren't being made on speculation alone. At mid-year, Rheinmetall's order backlog stood at €63.8 billion, up from €49.9 billion a year earlier. The air defense segment lifted its first-half revenue to €478 million.
Recent contract awards reinforce the picture. In late August, the Bundeswehr placed its first call-off for a modular camp for up to 2,000 soldiers in Lithuania, worth €250 million to build plus around €40 million annually for operations. Earlier, the military had ordered 149 additional mobile rescue stations at a gross volume exceeding €500 million.
On the technology front, Rheinmetall's Skymaster command and weapon engagement system was successfully integrated with Hensoldt's Twinvis passive radar during the NATO-compatible exercise "Timber Express 2026," strengthening the company's position in air defense.
Market Skepticism Persists
The stock market, however, remains unimpressed. Shares closed Friday at €1,152.40, down 2.1 percent on the day. The stock has lost 26 percent since the start of the year and sits 43 percent below its 52-week high of approximately €2,007, set in early October. The slide reflects investor concerns about margin pressure and the capital tied up in these ambitious investment plans — even with full order books.
Rheinmetall at a turning point? This analysis reveals what investors need to know now.
Not everyone shares that pessimism. Morningstar's analysis pegs the fair value at €2,380, more than double the current trading level, suggesting the market may be overlooking the long-term earnings potential.
What's Next
Key decision points are approaching. A decision on next steps is expected in the first week of September, with a €25 million proposal slated for December 9. Management will also present at the Berenberg Stockholm Seminar in early September and later at Morgan Stanley's "Industrial CEOs unplugged" conference.
The central question for investors: is the Kassel build-out a prudent capacity expansion ahead of confirmed billion-euro orders, or an expensive bet on demand that has yet to materialize? The answer to the Alstom question — and the fate of those 900 locomotive workers — will arrive within weeks.
