Sky-Watch

Danish manufacturer of tactical fixed-wing UAS for ISTAR, including the hand-launched RQ-35 Heidrun and the long-range RQ-70 Dainn, together with its own Zentra sensor payloads and mission software.

Sky-Watch A/S is a defence technology company based in Støvring, Denmark, founded in 2009 and today part of the US-listed AIRO Group Holdings. It develops unmanned aircraft systems for intelligence, surveillance, target acquisition and reconnaissance (ISTAR) for armed forces and runs an APAC office in Singapore. According to the company, its systems are in service with NATO and allied forces and have been used in Ukraine since 2022.

The RQ-35 Heidrun is a backpack-portable, hand-launched fixed-wing UAV with a maximum take-off weight of 3.35 kg, a wingspan of about 1.6 m, up to 180 minutes of flight time and a transmission range of up to 50 km; it lands by deep stall. The RQ-70 Dainn, introduced in June 2026, is a larger platform for deep-reach ISR and target acquisition with up to eight hours of endurance, up to 100 km of range and fixed-wing, long-range or VTOL configurations. Both interface with C4I systems such as ATAK, DELTA and SitaWare and follow STANAG 2934.

Sky-Watch develops the Zentra sensor suite in-house, with stabilised EO, IR and combined EO/IR payloads and Zentra-Nav payloads that support visual navigation when GNSS is degraded. Its Mission Software provides AI-assisted detection, tracking and DRI workflows and hands target data to C4I and fire control systems. In June 2026 the Netherlands Ministry of Defence selected the RQ-35 Heidrun for company-level ISR operations after a tender managed by COMMIT, with deliveries in 2026 and a seven-year support programme; in October 2026 the company reported a framework agreement with the NATO Support and Procurement Agency.
