Emerging Defense Industries and the Growing Espionage Threat: A Case Study of Türkiye

Defense industries have become one of the most critical pillars of national sovereignty and strategic autonomy in today’s world, where technological developments are accelerating and geopolitical competition is intensifying. The case of Türkiye is particularly noteworthy, as it illustrates how the achievements of emerging powers in the defense sector simultaneously generate growing security vulnerabilities. This study constitutes a single-case analysis grounded in qualitative research methods and draws on multiple sources, including official reports, think-tank publications, academic literature, and media accounts. The article examines six major espionage incidents directly targeting the Turkish defense industry and, through comparative analysis, identifies recurring patterns and threat dimensions. The findings reveal that Türkiye’s rapid advancements in unmanned aerial vehicles, guided missile technologies, and electronic warfare systems have rendered it a priority target for hostile actors. The espionage methods identified include phishing-based cyberattacks, leaks of classified project information, illicit data trade via social media platforms, and covert corporate operations. Turkish intelligence institutions, most notably the National Intelligence Organization (MİT), have developed a range of countermeasures in response, such as preventive briefings, security screenings, and targeted operations. Nevertheless, vulnerabilities in digital infrastructure and insider threats continue to expose critical components of defense projects to external exploitation. In conclusion, espionage activities directed at Türkiye’s defense sector are multifaceted, adaptive, and strategically consequential. These threats undermine not only the security of individual companies but also broader national security strategies and international credibility. The Turkish case underscores a wider reality: the faster an emerging defense industry advances, the greater the incentive for adversaries to penetrate it.
