Stella Tecnologia conducted its first test flight of the Albatroz tactical UAV featuring the ATJR 15-5 turbine engine on 17 December 2025 at Santa Cruz Air Base, Brazil. This new configuration allows the Albatroz Vortex to achieve a top speed of 250 km/h.

The ATJR 15-5 turbine, developed by Brazilian AERO Concepts, has a thrust capability of 500 N and received funding from the Brazilian state-owned Funding Authority for Studies and Projects. The development of the Albatroz Vortex is part of a Technology Development Cooperation Agreement signed with the Brazilian Air Force in November 2025.

Stella has been integrating the turbine into the UAV since April 2024, following a cooperation agreement with AERO Concepts. The Albatroz was previously equipped with a modified 215 hp Desert Aircraft DA215 engine, achieving approximately 50 flight hours.
