Problem

Small, low-cost drones are increasingly used to disrupt civilian infrastructure and create military and security threats, yet conventional detection systems can miss them or confuse them with birds and other airborne clutter. The economics of failure are substantial: the 2018 Gatwick disruption reportedly cost stakeholders more than £50 million, while drone activity in the Red Sea was associated with doubled global shipping costs. The principal “killer” use case is reliable protection of airports and other restricted airspace, where a missed drone can create safety risks and prolonged operational shutdowns.

The same problem applies to critical infrastructure, venues, VIP protection and defence. DroneTector is aimed at the difficult end of the market—small, low-signature aircraft, including inexpensive quadcopters and autonomous swarms—where false positives waste operators’ attention and false negatives leave genuine threats undetected.

Product / Service

DroneTector provides a hardware-led airspace-security system centered on high-frequency millimeter-wave radar engineered to detect, track and classify small drones. Its radar is combined with camera and acoustic arrays to improve identification, distinguish drones from birds and clutter in real time, and provide operators with more reliable situational awareness. The sensors can operate independently or as part of a distributed detection network, allowing deployment to scale across complex environments.

The public description points to an enterprise, infrastructure and defence deployment model rather than a consumer product: the company invites organizations responsible for airports, critical infrastructure, venues, VIP protection and defence to engage directly. The benefit is earlier and more dependable awareness of what is actually in protected airspace, including targets that other detection systems miss.

Market

DroneTector competes in counter-UAS, drone-detection radar and broader airspace-security markets. Its relevant competitive set includes radar and integrated detection providers such as DeTect, Weibel, Robin Radar and QinetiQ’s Obsidian counter-drone system, alongside broader counter-drone vendors. The category is expanding rapidly; one market forecast cited in the research projects the global anti-drone market from $4.48 billion in 2025 to $14.51 billion by 2030.

The company appears to be an early-stage deep-tech venture rather than an established revenue-scale supplier. DroneTector Limited was incorporated in November 2023 and remains active; the company now presents publicly under the Milliray name, is listed as an active YC Winter 2026 company, and reports support from the UK Ministry of Defence’s Defence and Security Accelerator, NATO DIANA and the Royal Academy of Engineering. No named customer deployments, revenue figures or commercial contracts were found in the available evidence, so the most defensible diligence characterization is pre-revenue or not-yet-publicly revenue-generating, with traction currently demonstrated mainly through technical development, institutional support and market outreach.
