Obriy

Obriy is a professional unmanned aerial vehicle mission simulator developed by the Kyiv-based firm Twist Robotics. Designed for operator qualification, unit training, and mission planning, the software recreates modern combat conditions to allow military personnel to rehearse operational scenarios without risking personnel or physical equipment. The platform covers more than 50,000 square kilometers of detailed operational terrain, derived from real satellite data and frontline topography. It is positioned as a NATO-compatible training tool, intended for use by Ukrainian combat units, training centers, and international partners to develop mission workflows and prepare crews for unpredictable operational environments.

The simulator’s technical architecture focuses on replicating the full operational environment of mission execution, including terrain, weather conditions, and electronic warfare effects. It simulates the impact of these factors on communication, video transmission, and flight control. Obriy supports a wide range of UAV types, including 5-inch, 7-inch, and 10-inch FPV platforms, fixed-wing UAVs, and VTOL or tail-sitter configurations. Specific models available for training include the Saker Scout, Saker Hunter, VB 140, Blyskavka, Bullet, and Sting. The system integrates with third-party simulators, radars, air defense systems, infantry modules, and external situational systems, allowing it to operate as part of a shared synthetic environment. It also supports the simulation of ground assets such as armored vehicles, artillery, infantry, logistics transport, and fortifications within the same digital battlespace.

A significant update to the platform, designated “Obriy Antishahid,” was presented in March 2026, focusing on training crews to intercept long-range strike drones. This version simulates the full cycle of small air defense, from target detection to the decision to destroy it. The update includes a radar module that simulates radar operations at distances of up to 25 kilometers. It reproduces the detection and tracking of targets on a tactical map, crew coordination, and the timing of interceptions. The simulator allows operators to practice the interaction between pilots and navigators using models of the Octopus and Sting interceptors. To increase realism, scenarios incorporate the presence of infantry and armored vehicles, as well as electronic warfare interference and communication limitations.

Twist Robotics began developing the interceptor training direction in the summer of 2024, scaling the solution to small air defense units throughout 2025. The company reports that the simulator has yielded practical results, citing instances where operators successfully shot down real Shahed drones during their first combat duty after completing a two-week virtual training course. As of the latest reporting, the platform is used free of charge by over 150 combat units and 50 training centers of the Defense Forces of Ukraine. The system is available in configurations for individual operator training, shared training environments with DIS integration, and R&D activities for validating new UAV platforms.
