Stella Tecnologia successfully completed the first test flight of its Albatroz tactical UAV, now powered by the ATJR 15-5 turbine engine, on December 17, 2025, at Santa Cruz Air Base in Brazil. This new configuration enables the UAV to reach speeds of up to 250 km/h and is part of a development initiative in collaboration with the Brazilian Air Force and AERO Concepts. The project, funded by the Brazilian state-owned Funding Authority for Studies and Projects, marks a significant advancement from the UAV's previous engine configuration.
