Quantum Systems is announcing major upgrades to its long-range intelligence, surveillance and reconnaissance (ISR) system, Reliant. Following Quantum Systems’ policy of continuous development and R&D, the new features significantly expand Reliant’s mission flexibility while maintaining the ease of deployment and low logistical footprint that define Quantum Systems’ platforms.

The latest generation of Reliant featured a hybrid-electric power unit and increases the system’s payload capacity to up to 9 kg, enabling a much broader range of missions. Depending on operational requirements, Reliant can now carry electro-optical sensors, laser-target designators, synthetic aperture radar (SAR), SIGINT and electronic warfare payloads, as well as SATCOM, relay and other mission-specific capabilities.

Despite its expanded capabilities, Reliant maintains its minimal logistical footprint with easy-packaging options and operations enablement for assembly by a two-person team and operations by a single operator. The hybrid-electric VTOL platform requires only a 10 × 10 metre (approx. 32 × 32 ft) launch and recovery area, making it independent of start- and recovery infrastructure and suitable for ship-based operations.

Europe’s security landscape is changing rapidly

As defence budgets rise and EU programmes expand, civil technology providers are becoming vital contributors to Europe’s strategic autonomy. The event will act as a neutral platform for dialogue between technology suppliers, integrators, and decision-makers shaping the next generation of European defence capabilities and aims to open doors between civil industry and defence procurement, providing practical insights.

Beyond the platform itself, Reliant is fully integrated into the MOSAIC UXS software platform, making it interoperable with other unmanned systems in multi-domain operations. Together with operator workstations, training, sustainment and lifecycle support, Quantum Systems delivers a complete long-range unmanned capability rather than a standalone aircraft.

Reliant also completes Quantum Systems’ Family of Aerial Systems, complementing the short-range Twister and the mid-range Vector AI platforms. Quantum Systems UAS solutions are already in service with a range of NATO and allied armed forces, notably with the German Armed Forces and the Armed Forces of Ukraine.

Reliant is built around a secure European supply chain and supported by Quantum Systems’ growing industrial base, providing customers with a system without any Chinese components or ITAR restrictions.

“Reliant’s upgrades are the result of continuous feedback from military users and partners, and our answer to enhance long-range capabilities for NATO, Europe and our allies,” said Martin Karkour, Chief Revenue Officer at Quantum Systems. “We can now offer a truly unique capability, with a minimal logistical footprint, payload superpower and impressive range and endurance—completely built on a resilient supply chain. We are very proud of that.”
