The Center for Autonomous Robotic Systems reported on the progress of work on the Meridian amphibious-type unmanned aerial system. The project has moved into the stage of manufacturing parts and assemblies for prototype models.
Key airframe elements have already been produced: flaps, fin, floats, elevators and rudder, stabilizer, and ailerons. At the same time, production of the wing and the tail section of the fuselage is continuing.
In addition, the company reported a high degree of readiness of the onboard equipment. Manufacturing of the servo drives, propeller, ground control station, engine units, as well as component parts of the onboard radio-electronic equipment (BREO), is nearing completion. Cables and connectors for the onboard network and power supply system units are ready. An important milestone was the successful testing of the parachute recovery system.
At the end of 2025, a large-scale model of the Meridian already confirmed its hydrodynamic qualities in the test basin of the Central Aerohydrodynamic Institute (TsAGI). Preparations are currently underway for the next stages: tests on open water and operation in a wind tunnel.
The Meridian is a fixed-wing unmanned amphibious aircraft with a takeoff weight of up to 2.5 tons and a payload capacity of 700 kg. Its flight range reaches 1,200 km, endurance is up to 11 hours, and cruising speed is about 200 km/h. The aircraft can take off and land both on land and on water, operates at temperatures from -45 to +35 °C, and can perform flights without satellite navigation.
