Milipol 2025: France's Elistair unveils Khronos Dual Payload advancing aerial tactical support capabilities.

France's Elistair introduced its Khronos Dual Payload tethered drone system at Milipol 2025 in Paris, integrating a Silvus StreamCaster 4200P tactical radio and a DragonEye2 electro-optical camera. The configuration combines secure communication, relay, and persistent ISR inside a single aerial platform.

Elistair announced a significant expansion of its tethered drone portfolio at Milipol 2025 in Paris, including the debut of the Khronos Dual Payload system, which combines communications and imaging capabilities in a single platform. The release confirms that the system integrates a Silvus StreamCaster 4200P tactical radio with a Nextvision DragonEye2 electro-optical camera, enabling operators to establish a secure communication relay while maintaining uninterrupted surveillance.

Designed to function as a multi-mission aerial mast, the Khronos Dual Payload provides tactical teams with secure communication, relay, and ISR (Intelligence, Surveillance, and Reconnaissance) capabilities. Its role as a Variable Height Antenna (VHA) extends the reach of tactical mesh networks. This ensures reliable connectivity even in GPS-denied environments or challenging terrain, where traditional systems might falter.

Elistair emphasizes that the new configuration maintains the performance characteristics that have defined the Khronos platform. These include a 24-hour operational tethered endurance and a maximum operating altitude of 60 meters. This long-duration aerial persistence allows field units to maintain overwatch or uninterrupted communications without the limitations of battery-powered drones, making it particularly suited for special operations and rapid-deployment forces.

The Dual Payload system is the latest response to evolving battlefield requirements, where interoperability and operational consolidation are increasingly critical. Elistair developed this upgrade to meet the growing demand for systems that merge real-time situational awareness with robust digital communications, all within a single, operator-controlled platform.

According to the company, the Khronos Dual Payload has been tailored for modern defense. It supports operations from special forces missions to conventional deployments. The system delivers rapid, flexible, and resilient solutions. It unifies data gathering and communications at the tactical edge.

The unveiling at Milipol 2025 highlights Elistair’s broader strategy to push tethered drone technologies beyond ISR roles. Embedding dual-functionality into the Khronos platform aims to deliver mission-ready tools for operational efficiency. This approach supports teams in increasingly complex and contested environments.
