Europe is Rearming, Wall Street is Pumping money: Why India Must Learn to Own Its Defence Supply Chains

Europe’s military buildup is creating opportunities for American investors, private-equity firms and defence technology companies. For India, the lesson is clear: becoming a major defence power requires more than assembling weapons at home. It requires control over the critical technologies, industrial capacity and supply chains that keep military production moving.

Europe’s rearmament is no longer just a story about governments ordering more tanks, aircraft and missiles. It is increasingly a story about who finances defence manufacturing, who owns the companies producing critical components, and who controls the technologies that determine military readiness.

Aerospace and defence mergers and acquisitions are emerging as a major channel for this transformation. According to the Aerospace & Defense M&A Report 2026, published by Ropes & Gray LLP on October 7, defence investment is being reshaped by rising military expenditure, technological competition and growing private-capital participation.

The implications extend well beyond the United States and Europe. For India, which is seeking to expand domestic defence manufacturing while reducing dependence on foreign suppliers, the emerging model offers an important strategic lesson: military self-reliance is impossible without industrial ownership, technological depth and control over critical supply chains.

Europe’s Rearmament Is Becoming a Financial Revolution

European governments are increasing defence spending as the continent reassesses its security requirements. Russia’s war against Ukraine, uncertainty surrounding the long-term American security commitment and NATO’s expanding military ambitions have strengthened the case for rebuilding Europe’s defence-industrial capacity.

The European Union’s Security Action for Europe initiative, or SAFE, forms part of this effort. Alongside national spending increases and other financing mechanisms, European governments are attempting to mobilise substantial resources for military procurement and industrial expansion.

Germany’s changing defence posture is particularly significant. Higher expenditure and procurement reforms could support manufacturers involved in armoured vehicles, ammunition, electronics and other military equipment.

But governments cannot build a resilient defence-industrial base simply by increasing budgets. They also need factories, skilled workers, specialised suppliers, advanced manufacturing capabilities and companies capable of delivering equipment at scale.

This is where private capital enters the picture.

The Ropes & Gray report identifies Europe as an increasingly important centre of aerospace and defence deal-making. Private-equity firms are acquiring manufacturers, consolidating fragmented businesses and positioning companies for eventual sales to strategic buyers. Venture capital is financing emerging businesses developing specialised military technologies.

The report identifies defence technology and services as its fastest-growing segment, with a compound annual growth rate of 22%, followed by aerospace at 16%, aircraft manufacturers, parts and components at 14%, and air, land and sea defence at 9%.

These figures point to an industry whose growth is no longer confined to traditional weapons manufacturers. Software, autonomy, sensors, electronics and specialised industrial components are becoming increasingly important to military capability.

GE’s $11.8 Billion Deal Reveals the Real Strategic Lesson

One of the report’s most significant transactions is GE Aerospace’s reported $11.8 billion acquisition of Consolidated Precision Products (CPP), a manufacturer of complex aerospace components.

The strategic significance of such a transaction lies in the importance of the industrial processes behind modern aircraft engines.

Advanced engines depend on precision castings, complex airfoils and components manufactured to exceptionally demanding specifications. These parts are difficult to produce, require substantial technical expertise and cannot always be replaced quickly when supply chains are disrupted.

The aerospace industry has experienced persistent production bottlenecks, while engine-related manufacturing challenges and wider supply-chain pressures have exposed the limitations of relying heavily on external suppliers.

For a major engine manufacturer, a supplier’s inability to deliver is not merely a procurement problem. It can delay aircraft deliveries, disrupt production schedules and affect relationships with airlines and other customers.

By acquiring a critical supplier, a manufacturer can gain greater visibility and control over production capacity, manufacturing processes and delivery schedules.

This illustrates a broader shift in industrial strategy. Outsourcing may reduce capital requirements and improve short-term financial efficiency, but it can also leave a company vulnerable when critical suppliers lack capacity
