In the coming weeks, OPTIMAL GROUP will once again take part in REPMUS26 and ARTEx26, continuing our commitment to developing, testing and validating innovative technologies in operational environments.
Across land, air and maritime domains, we develop advanced technologies, products and solutions for demanding defence and security applications.
Our multi-domain approach brings together unmanned systems, rocket and launch technologies, advanced composite structures, ballistic protection and other mission-critical solutions — taking technology from development and manufacturing through to field experimentation and operational validation.
REPMUS26 – Robotic Experimentation and Prototyping with Maritime Unmanned Systems
Led by the Portuguese Navy, REPMUS is a major multinational exercise focused on the experimentation and validation of unmanned systems in the maritime domain, bringing together operational users, industry and academia.
Following our participation in REPMUS25, including the successful maritime launch of the HUNTER-02 rocket from NRP Figueira da Foz, we look forward to returning to the field in 2026.
ARTEx26 – Army Technological Experimentation
Hosted by the Portuguese Army at Campo Militar de Santa Margarida, ARTEx26 focuses on testing emerging technologies in realistic defence scenarios and supporting their transition towards military application.
Our participation in ARTEx25 included the successful demonstration of the HUNTER-01 launch system and field testing of our composite ballistic protection solutions.
From land to air and maritime environments, OPTIMAL GROUP remains permanently in the field — developing, manufacturing, testing, learning and delivering.
Follow us as we take part in REPMUS26 and ARTEx26.
The future of defence technology is not only developed. It is tested in the field!
