NATO's 32 member states collectively spent over $1.4 trillion on defense in 2025, the first time all members simultaneously met the 2% GDP baseline. A binding pledge at The Hague to reach 5% of GDP by 2035 has triggered a structural procurement cycle that is reshaping demand across the global aerospace and defense market, now valued at approximately $847 billion to $918 billion. With the Ankara Summit on July 7-8, 2026 serving as the first compliance checkpoint, contractors from Rheinmetall to Lockheed Martin are accelerating production capacity in anticipation of a decade-long spending surge.
All 32 NATO Members Hit the 2% Target for the First Time
Combined defense spending by NATO nations in 2025 topped $1.4 trillion, according to Secretary General Mark Rutte's Annual Report released on March 26, 2026. All military-equipped NATO nations met the 2% GDP baseline for the first time, with many reporting steep year-on-year increases.
The United States remained the single largest contributor, with its share equaling 3.19% of its national GDP, though that figure fell slightly from $850 billion the previous year when total alliance spending stood at roughly $1.3 trillion. Non-US contributions rose approximately 20% year-over-year, a shift with structural significance for European defense industrial policy.
The milestone follows the 2025 Hague Summit's binding commitment requiring all 32 NATO members to invest 5% of GDP annually by 2035, structured as at least 3.5% of GDP for core military requirements and up to 1.5% for cybersecurity, critical infrastructure, and defense industrial capacity. All member states except Spain, which received an exemption, are party to the commitment.
The Hague Framework and What $2.9 Trillion in Annual Spending Means
The scale of the commitment is historically without precedent among peacetime alliances. If all NATO allies met the 3.5% core target by 2035, they would need to allocate approximately $1.4 trillion more in annual military spending than they did in 2024. Total NATO annual military spending would reach roughly $2.9 trillion under that scenario, and hitting the full 5% target would require an additional nearly $2.7 trillion, bringing total spend to around $4.2 trillion per year.
NATO Secretary General Rutte described the commitment as a "transformational leap" and a "quantum leap" for collective defense. The practical constraint, however, is industrial capacity rather than political will. Munitions shortages, MRO backlogs, and labor gaps across the defense manufacturing base represent the binding constraint on how quickly those budget commitments translate into delivered equipment. -
At the Ankara Summit on July 7-8, 2026, allies are expected to present their national plans for accelerating toward the Hague targets, making it the first concrete compliance test of the 5% pledge.
The Ankara Summit: A Procurement Catalyst Under Transatlantic Pressure
The Ankara gathering arrives amid significant friction in the transatlantic relationship. Disputes over Iran and Greenland, among other issues, have heightened tensions in the transatlantic partnership ahead of the summit, though defense spending and scaling up industrial output remain shared values on both sides of the Atlantic.
Germany is circulating a proposal to commit €70 billion in military aid to Ukraine, with €30 billion from an already-agreed EU loan and €40 billion in bilateral member state commitments, which is expected to be announced at Ankara. The proposal underlines how the political center of gravity in NATO burden-sharing has shifted toward Berlin under Chancellor Friedrich Merz following US troop reductions in Europe.
The Atlantic Council has noted that a precarious gap may emerge between the mindset shift and full implementation of a rebalanced defense posture, citing strategic lift, missile defenses, air refueling, and operational intelligence as key US enablers that European allies cannot yet replicate.
How NATO Spending Is Flowing to Aerospace and Defense Contractors
The procurement pipeline is already rewarding both European and US prime contractors. US prime contractors including RTX, Boeing, and Lockheed Martin are selling F-35s and Patriot batteries to European militaries through Foreign Military Sales, while European contractors such as Rheinmetall, BAE Systems, and Leonardo are capturing domestic procurement orders tied directly to EU rearmament budgets.
Rheinmetall represents the most visible industrial beneficiary of the cycle. The German defense group has forecast sales of approximately €50 billion by 2030, up from €10 billion in 2024, with growth driven primarily by its military vehicle systems, weapons, and ammunition divisions. Its operating margin is expected to expand to approximately 20% from 15% in 2024, and shares have risen roughly 900% over the past three years.
Within the European Union's parallel defense funding architecture, Thales leads with a €74.8 million cloud contract, Leonardo has drawn €162.4 million from the European Defence Fund, and Rheinmetall, Eurenco, and HENSOLDT have each secured grants of over €30 million to address Europe's ammunition production shortfall.
Global revenue across the top 100 aerospace and defense companies reached $922 billion in 2024, with demand strong across both civil and defense sectors, constrained by labor shortages and supply chain fragility rather than order flow.
The Global Aerospace and Defense Market: Size, Growth, and Where the Money Goes
The global aerospace and defense market is estimated at $918 billion in 2026 and is projected to reach $1.61 trillion by 2033, growing at a CAGR of 8.4%. Defense systems and services account for an estimated 58.2% of total market value in 2026, with North America holding a 45.2% share and Asia-Pacific at 21.8% and growing fastest.
An alternative estimate values the market at $899.65 billion in 2026, growing at a 6.2% CAGR, with expectations of reaching $1.18 trillion by 2030. Growth is attributed to next-generation military platform demand, autonomous and unmanned aerial systems adoption, and cybersecurity integration across defense networks.
Defense activities account for approximately 58% of total demand within the broader aerospace and defense sector, while commercial aerospace represents roughly 32%, and military aviation holds about a 41% share. Space and satellite systems contribute nearly 14% of sector value.
The MRO segment is a direct beneficiary of sustained spending. Global commercial aftermarket MRO demand is projected to grow at a 3.2% CAGR between 2026 and 2035, with the engine segment's share of total MRO demand expected to rise to 53%.
Supply Chain Constraints: The Binding Constraint on NATO's Ambitions
Budget commitments do not automatically translate into delivered capability. There is an acute supply gap in 155mm artillery shells and precision-guided munitions being replenished across NATO, with specialist munitions funds concentrating on this shortfall.
The EU is attempting to address this through dedicated industrial funding. Rheinmetall has a €300 million ammunition logistics contract entering decision stage in Q3 2026, while MBDA and RTX are competing for a €150 million enhanced air-defense contract expected to be awarded by August 2026.
US defense appropriations provide a parallel demand signal. The FY2026 US defense budget request includes $152.8 billion for procurement and $142 billion for research, development, testing, and evaluation, which anchors near-term demand for platforms, munitions, microelectronics, and digital defense programs.
Outlook: 12 to 24 Months
Three structural outcomes are probable over the near term. First, the Ankara Summit will crystallize national defense investment plans, converting political pledges into multi-year procurement contracts that provide visibility for contractors. Second, European defense industrial capacity will remain the binding constraint, with Rheinmetall, BAE Systems, Leonardo, and Thales each needing to expand manufacturing footprints substantially to meet contracted volumes. Third, the divergence between the US contribution rate and European spending velocity will continue to compress, shifting procurement leverage gradually toward European buyers.
Goldman Sachs has pointed to the EU's ReArm Europe plan as adding more than €800 billion of defense spend over the medium term, with European defense technology identified as a key growth opportunity linked to the 5% commitment. 24/7 Wall St.
The technology investment layer is expanding in parallel with hardware procurement. AI, big data analytics, and unmanned systems are seeing accelerating adoption to improve operational efficiency and combat capabilities, alongside growing investment in fuel-efficient aircraft and green defense technologies.
