Autonomous Military Systems: Development, Deployment, and Strategic Implications

Autonomous military systems are unmanned platforms endowed with increasing levels of self-direction and decision-making by artificial intelligence. They span aerial drones, ground robots, naval vessels, and undersea vehicles designed to operate with minimal human intervention. Unlike traditional remotely piloted systems, these platforms can perceive, decide, and act to varying degrees on their own. For example, the U.S. Department of Defense (DoD) defines an autonomous weapon system as “a weapon system that, once activated, can select and engage targets without further intervention by an operator”.

This burgeoning autonomy is enabled by advances in computing, sensors, and networking – part of a broader wave of “big data, AI, automated and autonomous systems” permeating every facet of warfare. Militaries worldwide view such technologies as key to gaining battlefield advantages in the coming decade. Indeed, NATO’s 2022 Strategic Concept highlights emerging tech like AI and autonomy as critical to future security. This report will survey the capabilities of autonomous systems in the air, on land, at sea, and undersea, and analyze their operational impact, doctrinal implications (including human-machine teaming and lethal autonomous weapons), and the strategic outlook through 2035.

All information is drawn from verified, reputable sources such as official defense agencies and research institutions, focusing on demonstrated or emerging programs rather than speculation.

The U.S. Air Force’s Skyborg program has demonstrated such autonomous unmanned aerial vehicles flying in formation with manned fighters to act as force multipliers. Unmanned Aerial Vehicles (UAVs) have been a cornerstone of military autonomy, evolving from remotely piloted reconnaissance drones to increasingly autonomous combat platforms.

Current military drones range from large high-altitude long-endurance (HALE) types (e.g. Global Hawk) to medium-altitude armed UAVs (like the MQ-9 Reaper) and down to small hand-launched scouts.
