An experimental sounding rocket aiming for a 4 km apogee, carrying a recovery system and a custom avionics stack — the first of its kind in the Western Balkans.
Excalibur is Argo’s first large-scale rocket programme. The airframe, recovery system and avionics are developed in-house, with the Hyrax flight computer handling telemetry and deployment on the way up and back down.
The build cycle runs bench validation first, then static fire and staged flight tests, before the full-altitude attempt.
