The European defense tech ecosystem as a new asset class for private equity
Decades of underinvestment, the prioritization of efficiency over capacity and a focus on a few, highly complex weapon systems (in some cases for dedicated foreign deployment scenarios) had led to an industrial landscape that had neither the necessary production volume nor the required speed for an adequate response. This wake-up call triggered a defense policy and federal budget response that became commonly known in Germany as the “Zeitenwende”, a term that aptly describes Europe’s profound strategic realignment. The realization that peace and stability, as the ultimate foundation of our free, democratic and social market economy, can no longer be taken for granted has led to a paradigm shift in defence budgets and industrial policy across the continent.
Global military spending reached a new record of USD 2,718 billion in 2024, with Europe being the main driver of this increase. The continent’s military spending rose by 17% to 693 billion US dollars. Individual countries recorded even more dramatic increases: Germany reached 88.5 billion US dollars (77.6 billion euros) in military spending, moving up from seventh to fourth place in the global ranking of military spending. This development is reflected throughout the NATO alliance.
For private equity investors, whose investment models and structures are generally designed for an investment horizon of five to ten years, this predictability of government spending in the defense sector creates an exceptionally stable investment environment.
The defense tech sector in Europe has evolved from a niche characterized by ethical concerns, regulatory hurdles and low capital flows to a core strategic asset class for private equity. The convergence of secure long-term government spending, a fundamental paradigm shift in military doctrine and deterrence, and a changing ESG narrative is creating a once-in-a-generation investment window.
For investors who are prepared to master the complexity of the sector, there are exceptional opportunities to participate in the technological modernization of European security and defence and to generate significant added value.
Networks and strategic positioning play a decisive role.
Success in the defense sector is less a question of capital alone and more a question of “smart capital”. PE funds looking to invest in defense tech need to actively build and maintain strategic networks with governments, militaries, defense contractors and technology clusters. Hiring former high-ranking military officers, procurement officials or defense company managers as advisors, venture partners or board members for portfolio companies can create a decisive competitive advantage.
