Tekever AR3

Portugal's tactical fixed-wing VTOL UAS — a gasoline-powered ISR platform battle-proven in Ukraine, fielded as the RAF's StormShroud electronic warfare asset, and the hardware backbone of Europe's newest defence-technology unicorn.

Overview

The Tekever AR3 is a fixed-wing, gasoline-engine intelligence, surveillance and reconnaissance (ISR) unmanned aerial system (UAS) with an optional vertical take-off and landing (VTOL) kit. Designed by Portugal-based TEKEVER, it fills the gap between small electric quadcopters and larger medium-altitude long-endurance platforms. The airframe first gained operational relevance through an expansive UK Home Office maritime-surveillance contract and then became one of the most combat-validated NATO-side tactical drones after years of intensive use by Ukrainian forces. In its upgraded AR3 EVO guise and the Royal Air Force’s StormShroud electronic-warfare variant, the platform has steadily expanded from pure ISR into suppression of enemy air defences and manned-unmanned teaming.

Development

TEKEVER was founded in 2001 as a technology company, progressively shifting into autonomous systems. The AR3 product line consolidated around 2015–2019, and the UK Home Office awarded a maritime surveillance-as-a-service contract around 2019 that gave the drone its first large institutional launch, a deal later reported as worth up to £1 billion UK Defence Journal. When Russia’s full-scale invasion of Ukraine began in 2022, the British government started purchasing Tekever drones through Task Force Kindred on behalf of Ukraine, with cumulative spending reaching approximately £270 million as of mid-2026 Sky News. By May 2025, as TEKEVER confirmed unicorn status following a funding round that included the NATO Innovation Fund, the company disclosed that its AR3 and AR5 platforms had together accumulated over 10,000 operational combat flight hours in Ukraine FlightGlobal TEKEVER. The combat feedback fed directly into the AR3 EVO redesign, unveiled in February 2026 AR3 EVO.
