Abstract

Today (mid-2026) UASs are a mature technology, quickly expanding, with two distinct tracks: a civil/commercial ecosystem that is moving from hobbyist and line-of-sight ops toward scaled commercial BVLOS and logistics, and an advanced industrial ecosystem that is rapidly adopting increasingly autonomous, networked, and innovative drone types (from tactical ISR to loitering, delivery, and swarm concepts). Regulators (FAA, EASA, and national authorities) are actively updating rules to enable safe BVLOS and integrated operations; at the same time, demand for counter-UAS capabilities is surging. This study presents an extensive review of UAV technologies, outlining their applications in both civilian and industrial domains. It further analyzes principal use cases alongside the related technical and operational challenges. Moreover, prospective research directions are proposed with the aim of advancing the technology framework. The insights provided are intended to offer meaningful guidance and inspiration for researchers in this area. The paper also emphasizes the existing framework while discussing potential future developments.
