During Exercise Bold Machina 24, NATO Special Forces divers tested underwater sensors that may be used to protect critical underwater infrastructure (CUI) in the future. Dive teams from thirteen nations participated in the exercise.

The exercise was held in La Spezia, Italy, in November and co-hosted by Allied Special Forces Command (SOFCOM) and NATO’s Centre for Maritime Research and Experimentation (CMRE). The divers were challenged to sneak past a variety of industry-developed detection systems in a “man-versus-machine” challenge.

Scientists from CMRE also showcased artificial intelligence (AI) detection systems and virtual reality tools designed to identify and respond to suspicious undersea activity.
