European Automakers Turn to Defense—Can They Save Jobs, or Just Lose More Money?

The European auto market is stuck in a deep structural slump. While full-year 2025 sales saw a modest 2.4% increase to almost 13.3 million vehicles, the sector remains a staggering 2.5 million vehicles smaller than its 2019 peak. This isn't a cyclical dip; it's a persistent deficit that has defined the industry's trajectory for years. The recent uptick offers little comfort, as it arrives against a backdrop of a perfect storm that has eroded the sector's foundation.

The pressures are multi-pronged and intensifying. First, the promised electric transition has become a costly burden. European manufacturers are scrambling to catch up with technological leaders, forcing massive investments that will pressure profit margins for years to come. Second, demand for EVs themselves is slowing, creating a painful gap between investment and return. Third, and most critically, European automakers are losing ground to Chinese competitors who enjoy a powerful cost advantage. These rivals benefit from significant state subsidies, allowing them to flood the European market with competitively priced vehicles. The EU's 2024 tariffs have done little to close the gap, as Chinese firms have largely absorbed the costs, maintaining their price edge.

This structural disadvantage is playing out in real-time. In the first months of 2026, while European sales stagnate, Chinese EV maker BYD reported a 175% year-on-year increase in deliveries to Europe. The result is a relentless squeeze on European market share and profitability. The financial toll is clear: the Stoxx 600 Automobiles index has fallen 30% over the past five years, with major players like Volkswagen and Stellantis shedding over half their market value. In 2025, Volkswagen shut its first auto plant in history, and Stellantis lost money in the first half of the year. The industry's core business is failing, creating the conditions for a dramatic pivot.

Defense as a Macro Cycle Play: Scale and Sensitivity

The pivot to defense is a direct response to a new macro cycle. The war in Ukraine has triggered a geopolitical realignment, forcing European governments to confront a stark reality: their defense budgets were chronically underfunded for a decade. This is no longer a niche market. EU member states' defense expenditure is surging, expected to reach €381 billion in 2025, a 62.87% increase from 2020. The target is clear: a steady climb toward NATO's 2% of GDP benchmark, a commitment that has now become a strategic imperative. This is a powerful, secular tailwind for the defense sector.

Yet, the scale of this new market is critical to assess. The European defense market is projected to grow at a robust 6.42% CAGR, reaching $194.39 billion by 2031. That is a significant sum, but it remains a small fraction of the auto industry's footprint. The European auto market was valued at $1.42 trillion in 2024 and is projected to expand to $3.3 trillion by 2035. In other words, even at its peak, the defense market represents roughly 6% of the auto market's size. This is not a replacement; it is a niche expansion within a much larger industrial base.

The sensitivity of this defense cycle is also noteworthy. Its growth is directly tied to geopolitical risk and political will, which can be volatile. The current surge is a reaction to a specific crisis, and its sustainability depends on the perceived threat level. In contrast, the auto market, despite its current slump, is driven by broader, more persistent forces: population trends, urbanization, and the long-term shift to mobility services. Defense spending is a discretionary budget item for governments, while auto production is a core component of industrial output and employment.

The bottom line is one of capacity and credibility. European defense firms have the technical capability to fill the gap, but the market simply isn't large enough to absorb the massive industrial capacity and workforce currently idled by the auto slump. The pivot is a sensible move to capture a growing, well-funded sector, but it is a tactical adjustment, not a strategic cure. The credibility of the European defense industry will be tested by its ability to deliver on time and budget, while its scale will always be constrained by the fundamental arithmetic of the two markets.

Operationalizing the Trade: Capacity, Credibility, and Cycles

The pivot from wheels to weapons is moving from theory to concrete plans. Renault is developing a ground-based drone for military and civilian use, following a partnership announced in January to produce aerial drones in France. Meanwhile, German automaker Volkswagen is reportedly in talks with Israeli defense firm Rafael to produce parts for the Iron Dome missile-defense system, with plans to convert its factory in Osnabrück into a facility for these components. These are the first tangible steps of what analysts have dubbed the "anything but autos" trade, a direct attempt to leverage existing industrial muscle in a new direction.

The potential benefits are clear. Defense contracts often promise stable, high-margin work, a stark contrast to the razor-thin profits in the current auto slump. For companies like Volkswagen, which faces deteriorating profitability and plans to cut 35,000 jobs, repurposing idle capacity could be a lifeline. The Osnabrück plant, slated for closure in 2027, could see its output redirected, potentially saving up to 2,300 jobs. More broadly, defense spending is a government-backed, discretionary budget item that is currently surging, offering a predictable revenue stream as Europe rearms.

Yet, the operational hurdles are substantial. The defense industry operates on a fundamentally different scale and rhythm than automotive manufacturing. It is dominated by small-batch production, not the high-volume assembly lines that define the auto sector. As Germany's largest trade union, IG Metall, noted, transferring large numbers of workers from automotive to defense is "unrealistic" because the two sectors operate too differently. This mismatch creates a credibility test: can auto firms adapt their lean, efficient systems to the bespoke, complex demands of defense production without crippling costs or delays?

Ethical concerns add another layer of friction. The shift from building consumer vehicles to producing weaponry could spark internal resistance and reputational risk. Workers may face a difficult choice between preserving a job and contributing to a defense product, raising questions about morale and social license. This internal tension could complicate the transition, turning a strategic pivot into a source of operational instability.

Viewed through the macro cycle lens, the defense pivot is a sensible tactical adjustment to a powerful geopolitical tailwind. But it is not a cure for the industry's deeper structural problems. The defense market, while growing, remains a small fraction of the auto market's size. The real test is whether this capacity shift can be executed efficiently and credibly, or if it merely represents a costly, disruptive reallocation of resources in a sector already struggling to find its footing.

Catalysts and Watchpoints for the Thesis

The viability of the defense pivot hinges on a few critical watchpoints. The primary catalyst is the sustained execution of the EU's defense budget surge. The data shows a powerful trend: member states' defense expenditure is expected to reach €381 billion in 2025, up 11% from the prior year and a 62.87% increase since 2020. This isn't just a one-time spike; it's a structural shift toward NATO's 2% of GDP benchmark. The key question is whether this spending translates into concrete, timely contracts for European manufacturers. Success will depend on the EU Defense Fund's ability to create cross-border industrial projects that can absorb the scale of auto-industry capacity. Without this, the budget growth may simply flow to established defense primes, leaving auto firms on the sidelines.

The second watchpoint is commercial viability. The initial announcements from Renault and Volkswagen are promising, but they are just that-announcements. The thesis requires tangible production plans and order books to signal that these partnerships are more than PR exercises. Concrete details on contract values, production timelines, and the volume of components to be manufactured will be the first real test of whether the "anything but autos" trade can generate meaningful revenue. For Volkswagen, converting its Osnabrück plant is a potential lifeline, but only if it leads to a firm, long-term order from Rafael. The market will be watching for these milestones to move from concept to cash flow.

The overarching risk is cyclical reversal. The defense boom is a direct reaction to a specific geopolitical crisis. As noted, shifts in government priorities, coalition changes or budget trade-offs can change the pace and direction of defense spending. The recent escalation in global military activity is a positive catalyst, but it is inherently volatile. If geopolitical tensions ease or if economic pressures force governments to cut budgets, the core growth thesis for auto-defense partnerships could quickly unravel. The industry's pivot is a bet on a sustained, high-level geopolitical risk premium. If that premium fades, the entire narrative faces a steep correction.
