The New Era of Defense: From Value Trade to Growth Play
For decades, the defense industry was viewed as a stable “value trade”—a sector defined by massive contracts, slow-moving bureaucracies, and a handful of dominant players. That has changed. Driven by the rise of global conflict and a technological leap in AI, robotics, and unmanned systems, defense has transformed into a high-growth play.
This shift isn’t just about bigger budgets; it’s about a fundamental change in how war is fought and how military technology is developed. The current investment boom suggests a transition toward a more digital, asymmetric, and decentralized model of national security.
The Investment Boom: Primes vs. Next-Gen Tech
The financial markets are already reacting to this shift. Investment in US defense and aerospace ETFs hit a monthly record in March, with a staggering 573 per cent year-on-year increase as of the third quarter of 2025. While a significant portion of this capital still flows to the “primes”—established giants like Lockheed Martin, General Dynamics, RTX, and Northrop Grumman—the real excitement is shifting toward next-generation firms.
Companies like Anduril Industries represent this new wave. These privately owned firms are scaling rapidly, focusing on software-first approaches to hardware, and recently doubling their valuations. Their rise is fueled by the reality of modern asymmetric warfare, where smaller nations can challenge incumbent powers by using cheap, scalable technology rather than relying solely on expensive, legacy hardware.
The Three Ds: Disruption, Dual Use, and Decentralisation
To achieve better security outcomes, modern military forces must move beyond traditional procurement and adopt what are known as the “three Ds”:
- Disruption: Replacing leisurely, single-purpose equipment with agile, AI-driven systems.
- Dual Use: Integrating commercial technology into military applications to increase speed and innovation.
- Decentralisation: Moving production and data centers closer to home to ensure supply chain resilience and redundancy.
The decoupling of American and Chinese tech stacks has accelerated this trend, creating a vacuum that startups in both countries are racing to fill. The goal is to move away from a highly concentrated model toward one that is distributed and resilient.
Breaking the Military-Industrial Complex
Despite the innovation in the private sector, government institutions are struggling to keep pace. The traditional US military-industrial complex is often too rigid for the 21st century, leading to munitions shortages, budget overruns, and an inability to control maritime chokepoints using expensive hardware alone.
However, there are signs of a narrative shift. The US Navy’s recent shipbuilding plan emphasizes speed, flexibility, and the use of systems that can be produced at volume and adapted in real time across multiple yards and suppliers. Jerry Hendrix, the Office of Management and Budget’s shipbuilding tsar, has pointed to the “Finnish model” as a template. This approach involves building Arctic icebreakers both domestically and in Finland, a strategy that could guide the $65.8bn in new shipbuilding financing requested by the president.
The Frontier of Hyperlocal Logistics
The most radical shift is happening in logistics. In a world of drone warfare, any visible supply line is a target. This necessitates a move toward “hyperlocal” production—creating supplies exactly where they are needed.
A prime example is the $9mn US Army contract awarded to Biosphere. The company is developing a portable biomanufacturing system that can produce protein-based food rations for troops using only air, water, and electrical energy. This technology, which biologist Molly Jahn previously worked on at Darpa, is moving from the realm of fiction to commercial viability.
According to Jahn, this is part of a larger transition. Referencing Thomas Kuhn’s The Structure of Scientific Revolutions, she suggests we are exiting a period of “ordinary” science and entering a period of “extraordinary” disruption. This shift will likely revolutionize not just defense, but almost every major industry.
Key Takeaways for Investors and Strategists
- Diversification of Power: While “primes” provide stability, the highest growth potential now lies in AI-centric defense startups.
- Resilience over Concentration: The focus is shifting from a few massive platforms to many smaller, distributed nodes of production.
- Commercial Integration: The “dual-use” model is becoming the standard, bringing commercial speed to military procurement.
- Logistical Revolution: Biomanufacturing and hyperlocal production are the next frontiers in reducing vulnerability on the battlefield.
The transition from a centralized military-industrial complex to a decentralized tech ecosystem is fraught with institutional friction, but the momentum is clear. Those who can bridge the gap between commercial innovation and government procurement will define the next era of global security.
