Never before has it been so clear that defense investment is not an expense, but an essential investment to guarantee the security and development of nations. Spain, in line with its European partners and other allies in our region, is leading a historic investment cycle, which, however, is only one part of the equation. To guarantee success, it is imperative to consolidate a strong, diversified, agile, resilient, and efficient national industrial base. A sector that does not depend solely on large contractors, but fosters an ecosystem where innovation flows, allowing Spain to remain at the forefront of technology. Strategic sovereignty necessarily depends on an industry capable of developing its own solutions, reducing external dependencies and boosting local talent.
From this perspective, Zelenza, a Spanish company that provides technological solutions and innovative services, has identified the seven trends that will define the defense sector in 2026 and that will most likely extend beyond that time: 1
Maintaining and Optimizing Economic Effort: While defense investment is expected to continue rising, the challenge for 2026 will not only be "how much," but "how." The key to industrial success will lie in capillarity: ensuring that the flow of economic resources descends from the large, leading corporations to the technology-based SMEs. It is in these more agile companies where the disruptive innovation needed for modern challenges often resides. Guaranteeing and strengthening this supply chain is vital for the health of the sector.
2. The Era of Massive Artificial Intelligence As Wellington aptly put it, warfare has always been about "knowing what lies on the other side of the hill." By 2026, that hill is digital.
Information superiority will depend on the widespread use of algorithms and artificial intelligence systems, as simply collecting data is no longer enough; it is necessary to process it in real time to accelerate the decision-making cycle. Thus, AI will be the engine that enables the management of uncertainty and provides a decisive operational advantage.
3. Unmanned Platform and Swarm Revolution The conflict in Ukraine has acted as an exponential catalyst, rendering the traditional "one pilot, one drone" model obsolete.
The year 2026 will mark the definitive takeoff of advanced command and control (C2) tools, designed to manage multiple assets simultaneously. We are heading towards a scenario of "intelligent" swarms with a high degree of automation, prepared to work in degraded communication environments, capable of operating in a coordinated manner across different domains while minimizing human intervention.
4. National Sovereignty: The End of "Let Them Invent It" Strategic autonomy also requires achieving the highest possible percentage of domestic development in the defense sector. Spain must aspire to own its critical capabilities and, in those cases where maintaining full national sovereignty is not feasible, the acquisition of foreign systems must be accompanied by a high level of technology transfer, thus guaranteeing the control, maintenance, and evolution of material resources within the national enterprise and administration.
5. Cross-cutting and Multi-Domain Approach. Modern operational art no longer operates in silos. Solutions cannot be exclusive to the land, naval, or air domains. The trend for 2026 demands a holistic and collaborative vision, where interoperability, integration, and joint operations are mandatory from the very first conceptual and design stages. Furthermore, the cyberspace domain, a cross-cutting layer that encompasses everything, connecting sensors and effectors in a unified combat network, must be a priority in this approach, with particular emphasis on the following point.
6. Cybersecurity or Irrelevance: Cybersecurity is no longer an add-on; it has become an existential requirement. In an environment saturated with electronic warfare (EW) threats, cyberattacks, and NAVWAR (navigation warfare), any system that is not robust and secure from its inception simply will not be operational. The premise is clear: be cybersecure or cease to exist.
7. Dual-Use Technologies: Two-Way Synergies. The boundary between civilian and military technology is blurring, to the benefit of both. The "militarization" of effective civilian solutions allows for the rapid and cost-effective adoption of innovations. Conversely, technology developed for defense must find its way into the civilian market, increasing the return on investment and ensuring that security advances benefit society as much as possible.
