Securing advantage with undersea tech innovation
Rear Admiral (Retd) Jon Pentreath on translating undersea innovation into operational effect ahead of UDT 2026, as defence assesses emerging subsea threats and capability gaps
ukdefencejournal.org.uk
The undersea domain is one of the most strategically significant arenas in modern defence, long providing advantages in times of peace while also proving a decisive factor in times of war.
....advances in artificial intelligence, data processing and quantum computing are likely to reshape the undersea battlespace through acceleration rather than disruption. For decades, navies have collected vast volumes of sonar and sensor data but lacked the computing power to exploit it fully. That is now changing. Machine processing is beginning to unlock that data at scale, while developments in compact computing architectures are pushing analytical capability closer to the tactical edge. The trajectory is therefore evolutionary, with autonomy representing the continuation of a long-term trend towards more capable, responsive and operationally effective undersea systems.
