Introduction: The strongest army in Europe by 2039

Germany has pushed through a 2026 federal budget that allocates €82.69 billion to the Bundeswehr, an increase of €20.2 billion on 2025 and the largest single-year increase in defence spending the country has approved since the end of the Cold War. Combined with the Sondervermögen — the €100 billion special fund agreed after Russia’s full-scale invasion of Ukraine — total federal defence spending now sits at around €108 billion for the calendar year.

Within the same week, Defence Minister Boris Pistorius unveiled Germany’s first ever standalone military strategy, alongside a refreshed capability profile, a personnel growth plan and a redesigned reserve strategy. The package amounts to one of the most consequential rethinks of German defence policy in living memory. Berlin has stated openly that its objective is to make the Bundeswehr the strongest conventional army in Europe by 2039 and to be capable of responding to a Russian attack on NATO territory should one materialise as soon as 2029.

For the United Kingdom, this is a development of first-order strategic significance. A militarily stronger Germany changes the political balance inside NATO, lifts the Demand/">Demand environment for the European defence industry, and creates new opportunities and competitive challenges for British primes and the Supply/">Supply chain. This article looks at how Germany got here, what is in the new budget and strategy, the implications for UK defence businesses and policy, and the risks and uncertainties around the trajectory.

Background: The Zeitenwende and the slow path to delivery

Germany’s pivot on defence began on 27 February 2022, three days after Russia launched its full invasion of Ukraine. Then-Chancellor Olaf Scholz declared a Zeitenwende — a turning point — and announced the €100 billion Sondervermögen, alongside a commitment to meet the NATO 2 per cent of GDP defence-spending target. The political moment was striking, but the implementation has been slower and more uneven than many initial commentators expected.

Bureaucratic procurement processes, parliamentary debates, contracting bottlenecks and a chronic underinvestment in the Bundeswehr’s basic infrastructure all combined to slow the pace at which the new money translated into capability. By 2024, observers were noting that the Sondervermögen would be largely committed by 2027 and that Germany would face a fiscal cliff if regular budget allocations did not rise sharply to take its place.

The 2026 budget directly addresses that concern. By lifting the regular defence allocation to €82.7 billion, Berlin has effectively committed to integrating much of what the Sondervermögen had been funding into the regular budget, securing the trajectory of Investment/">Investment beyond the current parliamentary term. Combined with parallel changes to the constitutional Debt/">Debt brake that allowed defence spending to be excluded from its provisions, the path is now financially credible in a way it was not a year ago.

The 2026 budget: What is in the package

The headline number — €82.69 billion for the Bundeswehr in 2026 — covers personnel, operations and Capital/">Capital Investment/">Investment. Underneath that figure, several specific allocations are notable.

Investment/">Investment in personnel is being prioritised. Germany aims to grow the active force from roughly 180,000 to around 203,000 by the early 2030s. To do that, it is reintroducing aspects of conscription on a selective basis, expanding Training/">Training capacity and increasing pay and accommodation budgets to make the armed forces more attractive as an employer.

Equipment programmes spread across the major service branches. The army is buying fresh tranches of Leopard 2 main battle tanks, Boxer wheeled armoured vehicles, infantry weapons and artillery systems including the Panzerhaubitze 2000 and the long-range PULS rocket artillery from Israel. The air force is taking delivery of further F-35 strike fighters, Eurofighters and replacement transport and intelligence aircraft. The navy is funding new frigates, submarines and uncrewed maritime systems.

Particular emphasis has been placed on sectors where Germany has been historically weak: air defence, where the country is funding multiple tiers from short-range systems through to the IRIS-T family and the Arrow 3 anti-ballistic-missile system; munitions, where stockpiles need to be rebuilt after deliveries to Ukraine; and digital and space capabilities, where the new budget includes significant Investment/">Investment in satellite communications, intelligence and resilience.

The defence ministry has also been clear that the procurement system itself is being reformed. The Bundesamt für Ausrüstung, Informationstechnik und Nutzung der Bundeswehr (BAAINBw), the federal agency responsible for procurement, has historically been a chokepoint. Pistorius has pushed through structural reforms aimed at faster decision-making and a higher tolerance for off-the-shelf solutions where domestic alternatives are not available on the required timeline.

The strategy: A new military doctrine

The strategic package unveiled in late April 2026 represents an even more significant break with the past than the budget alone. Germany has not previously had a standalone military strategy in its post-war history. The new document defines the country’s objectives, identifies its primary threat — clearly Russia — and sets out the operational concepts that the Bundeswehr will develop to meet them.

Several themes stand out. Speed is one: the new strategy emphasises the ability to deploy forces rapidly to NATO’s eastern flank, in line with the alliance’s New Force Model. Deterrence is another: Germany has explicitly stated that the credibility of conventional deterrence is foundational to alliance cohesion and is investing accordingly.

Integration with allies is a third: the strategy emphasises close cooperation with France, Poland, the United Kingdom and the Nordic states, particularly on capability development, exercises and joint doctrine. The willingness to work bilaterally and minilaterally outside the formal EU framework is a notable shift.

Internal resilience is a fourth: the strategy acknowledges that German society itself needs to be more prepared for crisis, including through expanded reserves, civil-defence planning and protection of critical infrastructure including energy, telecommunications and transport.

NATO’s 5 per cent target and Germany’s response

The NATO summit communiqué of late 2025 set out a new and significantly more demanding target: 5 per cent of GDP for defence-related spending by 2035, of which at least 3.5 per cent should be on core military expenditure and up to 1.5 per cent on broader defence and security-related items. The headline number was driven heavily by US insistence and reflects the alliance’s collective assessment of the deteriorating security environment in Europe and the Indo-Pacific.

For Germany, meeting that target by 2035 implies a near doubling of defence-related spending from current levels in nominal terms and, depending on growth assumptions, a significant share of overall federal expenditure. The 2026 budget is consistent with a measured ramp toward the target and with reaching the 3.5 per cent core threshold during the early 2030s.

Politically, the commitment is more difficult than the financial arithmetic suggests. German voters remain broadly supportive of higher defence spending in the abstract, but the trade-offs against social spending, infrastructure and the energy transition are real. Both the governing coalition and the opposition will be tested by the practical consequences of sustained spending at this level.

Implications for the European defence industry

The German defence industry is an immediate beneficiary of the new budget environment. Rheinmetall, the country’s largest defence prime, has reported a Backlog/">Backlog at multi-year highs and has been expanding capacity for ammunition, vehicles and air-defence systems. The company’s share price has been one of the strongest performers on the DAX over the past two years. Hensoldt, in defence electronics, and Diehl, in air-defence missiles, have similarly seen Demand/">Demand surge.

Beyond the German national champions, the spending wave is lifting the wider European defence ecosystem. France’s Thales, Italy’s Leonardo, Germany’s MTU Aero Engines and the trans-European missile group MBDA all stand to benefit from German orders or from the broader industrial pull that German rearmament generates. Smaller specialist suppliers in cyber, autonomy, sensors and additive Manufacturing/">Manufacturing are also riding the wave.

For UK defence companies, the picture is mixed. BAE Systems, the UK’s largest defence prime, has long-standing partnerships with German industry and benefits from increased Eurofighter and naval-systems Demand/">Demand. Babcock, QinetiQ and Chemring all have export-oriented businesses that should benefit from a stronger European defence market. At the same time, German policy is explicit about the importance of supporting domestic and European-Union industry, and UK firms outside specific government-to-government arrangements may face higher hurdles than their EU counterparts in some procurement processes.

Implications for the UK

For UK policymakers, German rearmament is welcome but requires a strategic response. Three issues are particularly important.

The first is industrial: the UK government, through the Strategic Defence Review and the integrated review refresh, has signalled an intent to accelerate UK defence-industrial Investment/">Investment. A more capable Bundeswehr means more orders for European primes; the UK needs to ensure its Supply/">Supply chain captures a share of that flow rather than ceding it entirely to continental and US firms.

The second is operational: a stronger Germany allows more effective burden-sharing within NATO. UK military planners, already stretched across commitments in northern Europe, the Indo-Pacific and elsewhere, can in principle rely more on German contributions to the eastern flank. That should free UK forces for other priorities, although in practice the picture will depend on how integrated UK-German operational planning becomes.

The third is political: a more militarily significant Germany inevitably becomes a more politically significant Germany inside NATO and on the broader European stage. UK foreign and defence policy needs to be calibrated to this new reality, with a focus on bilateral engagement, joint capability programmes and shared strategic communications.

Risks and uncertainties

Several risks deserve explicit attention.

The first is execution. Higher budgets do not automatically translate into capability. Germany’s procurement system has a long history of slipping deadlines and over-running on cost. Without sustained reform of the BAAINBw and disciplined programme management, the headline numbers may not produce the expected output for several more years.

The second is industrial capacity. Even where contracts are signed promptly, the European defence industrial base needs to expand significantly to deliver on the full range of new orders. Specific bottlenecks exist in solid rocket motors, semiconductors and certain rare materials. Investment/">Investment is being made, but lead times are long.

The third is political durability. The current governing coalition is committed to the new spending trajectory, but elections will eventually test that commitment. A future German government less convinced of the threat environment, or more sensitive to fiscal trade-offs, could slow the programme. The opposition has been broadly supportive to date but will face its own pressures on priorities.

The fourth is the broader European response. Sustainably higher German defence spending only delivers full alliance benefits if other major European NATO members — France, Italy, Spain, Poland and the UK — match the trajectory. There are encouraging signs in some capitals; the picture in others is more uneven.

The fifth is the trans-Atlantic relationship. The 5 per cent target is, in part, a product of US pressure. A change in the US administration’s posture on European security could either reinforce the trajectory or, in some scenarios, alter it. German planners are aware of this and are emphasising European autonomy in some areas as a hedge.

Expert-style analysis: What to watch

Several specific developments will shape the trajectory of German rearmament over the next 12 to 24 months.

The first is the autumn 2026 medium-term financial plan, which will indicate the trajectory of defence spending through 2030. A clear path to the 3.5 per cent core target by, say, 2032 would be a strong signal of seriousness.

The second is procurement decisions on a small number of strategic programmes: the Future Combat Air System, the Main Ground Combat System, deep-precision-strike weapons and integrated air-defence. Each of these will involve trade-offs between European and trans-Atlantic partners, and the decisions will set capability and industrial trajectories for decades.

The third is the operational rollout of new units, including the brigade Germany has committed to forward-deploy in Lithuania. Meeting the 2027 readiness milestone for that brigade is a key litmus test for the wider rearmament programme.

The fourth is the evolving security environment. Russia’s posture, the trajectory of the war in Ukraine, the Iran war and other regional crises will all shape the political space within which the budget trajectory is sustained.

Future outlook

Most informed analysts expect German defence spending to continue rising through the late 2020s, broadly consistent with the trajectory implied by the 2026 budget. The most plausible central case has Germany at 3.0–3.5 per cent of GDP by 2030, with the higher end of the NATO target reached in the early 2030s.

For the European defence industry, the 2025-2030 period is likely to be the strongest sustained growth phase in two generations. For the broader European economy, defence is becoming a meaningful new source of Demand/">Demand, supporting employment, Capital/">Capital Investment/">Investment and industrial innovation in a number of regions.

For UK policymakers and businesses, the strategic opportunity is significant but conditional. Capturing a fair share of the European defence wave requires proactive industrial policy, deeper alliances with European partners and continued Investment/">Investment in UK domestic defence capability.

Conclusion

Germany’s 2026 budget and the accompanying strategy package mark the most significant deepening of German defence policy since 1955. The country is committing real money — €82.7 billion in 2026, with a path toward NATO’s 5 per cent target — to a coherent strategic programme aimed at making the Bundeswehr the strongest conventional army in Europe by 2039.

For the United Kingdom, this is a moment that combines reassurance and challenge. A militarily stronger Germany is a stronger NATO, and a stronger NATO is a more secure UK. At the same time, the European defence industrial wave creates opportunities and competitive pressures that UK policymakers and industry will need to navigate with care.

The next decade will be defined by how effectively Germany converts its new financial commitments into deployable capability, by how durable the political consensus around defence proves to be, and by how the UK and other allies respond to the new continental balance. The numbers in the 2026 budget are striking on their own terms. Their full strategic significance will be measured in the security environment of the early 2030s.
