Autonomous Warfare Systems in Undersea Warfare: Operational Utility, Strategic Implications and Future Challenges

Abstract

The rapid advancement of artificial intelligence (AI), autonomous systems, sensor technologies, and network-centric warfare capabilities has transformed the character of maritime conflict in the twenty-first century. Autonomous Warfare Systems (AWS) are increasingly being integrated into naval operations to improve persistence, operational reach, surveillance capability, and decision-making speed in contested maritime environments. Within the maritime domain, undersea warfare has emerged as one of the most technologically demanding and strategically significant dimensions of modern conflict due to the increasing proliferation of advanced submarines, underwater sensors, and autonomous underwater platforms. The inherent stealth, survivability, and strategic utility of submarines continue to make them central instruments of sea denial, intelligence gathering, strategic deterrence, and power projection.

This paper examines the role of Autonomous Warfare Systems in undersea warfare, particularly in anti-submarine warfare (ASW), mine countermeasure operations, maritime surveillance, and network-centric naval operations. It analyses the operational utility of airborne, surface, and underwater autonomous platforms and evaluates how AI-enabled systems are reshaping contemporary naval doctrine. The study further explores lessons from recent conflicts, especially the Russia–Ukraine conflict, which has demonstrated the growing relevance of low-cost unmanned maritime systems in asymmetric warfare. In addition, the paper assesses the technological, strategic, ethical, and legal challenges associated with the deployment of autonomous systems in undersea operations.

The study concludes that while AWS significantly enhance operational effectiveness through persistent surveillance, force multiplication, and reduced risk to human operators, they are unlikely to replace human decision-making in high-intensity naval warfare. Instead, future undersea warfare will increasingly depend upon integrated human-machine teaming, robust command-and-control architectures, and internationally accepted legal and ethical frameworks governing the use of autonomous lethal systems.
