The rise of artificial intelligence (AI) and machine-learning–driven drones in Ukraine has permanently transformed the way wars are fought. This book explores the rapid development of hobby drone technology in modern warfare, from manually piloted systems to AI- and machine-learning–driven platforms. Combining real-world experience in Ukraine with clear technical explanation, it examines how unmanned systems evolved from experimental tools and hobby kits into critical battlefield assets.

Central to the book is a practical DIY drone build project, guiding readers through design, assembly, and configuration while explaining key components, software, and flight theory. The principles behind modern AI-assisted navigation, adaptive flight behaviour, and autonomous decision-making are explained in an accessible way.

The book also covers anti-drone defence systems, including detection, electronic warfare, and interception technologies, highlighting the ongoing contest between unmanned threats and countermeasures with real-life references.

This book is intended for educational and historical purposes only, offering readers an informative overview of the development and evolution of drone technology. It explores the connection between significant historical events and the advancement of unmanned aerial systems (UAS), providing context for how drones have influenced military, scientific, commercial, and recreational sectors. The content is based on publicly available information, engineering knowledge, and historical records, aiming to deepen understanding of the milestones that have shaped modern aerial robotics.

Drones, artificial intelligence, and machine learning have fundamentally redefined warfare, marking the greatest transformation in conflict since gunpowder reshaped the battlefield.

Readers must not interpret this material as instruction or endorsement for building, modifying, or operating drones in ways that breach local, national, or international laws. The construction or use of unauthorised or weaponised drones, particularly for surveillance or combat, is expressly discouraged. The authors and publishers do not support any unlawful applications of the information. Drone regulations differ across jurisdictions and are subject to frequent changes. It is each individual’s responsibility to remain informed about current legal and safety requirements concerning drone ownership and operation. This includes compliance with rules on airspace, registration, payloads, and flight conduct. This book promotes the ethical use of engineering knowledge and encourages responsible engagement with drone technology, underscoring the importance of legality, safety, and innovation.
