This paper examines the role of emerging technologies in strengthening maritime security through cooperation between the North Atlantic Treaty Organization (NATO) and the Arab Gulf states. It explores how artificial intelligence, autonomous systems, and digital transformation can improve monitoring, deterrence, and crisis response in critical waterways such as the Strait of Hormuz and Bab el-Mandeb. Within the context of regional instability and global competition, the study highlights how technology can mitigate threats including piracy, terrorism, cyberattacks, and environmental risks that endanger vital trade and energy routes. It also analyzes the strategic frameworks guiding both sides, namely the GCC’s collective security vision and NATO’s strategic concept and Istanbul Cooperation Initiative (ICI). Despite shared interests in protecting navigation and energy flows, cooperation faces limitations due to differing priorities and NATO’s restricted mandate beyond its territory. The paper proposes enhanced collaboration in crisis-management training, joint naval exercises, and AI-driven surveillance systems to improve readiness and interoperability. It concludes that integrating advanced technology within a pragmatic NATO-GCC partnership is essential to ensuring maritime stability and safeguarding global trade.
