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 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.

UK Type 31 Programme Rolls On with Roll-Out of Ship Two - Naval News

Babcock has achieved a major moment in the delivery of the Royal Navy’s Type 31, Inspiration Class programme, as two key milestones – the Steel Cut for HMS Bulldog and the Rollout of HMS Active –took place at its Rosyth facility in Scotland.

Type 31 Status

Current Project Status (As of early 2026):
  • HMS Venturer (Ship 1): The lead ship was launched (floated off) in June 2025 and is currently in the outfitting and systems integration phase at Rosyth.
  • HMS Active (Ship 2): In early 2026, the second ship emerged from the build hall and is undergoing fitting out.
  • HMS Formidable (Ship 3): Construction is underway, with the keel laid in December 2025.
  • HMS Bulldog (Ship 4): Steel was cut for the fourth vessel in early 2026.
  • HMS Campbeltown (Ship 5): The final ship of the class is planned for construction following the others.
The Type 31 frigate (Inspiration-class) has a targeted average production unit cost of £250 million (approx. $320–$336 million) to the UK MoD, with a total program cost of around £2 billion for five ships. The contract, awarded to Babcock in 2019, aims for a low-cost, general-purpose platform, though total costs per vessel may rise due to enhancements.

Type 26 Status

UK Royal Navy Construction Status
  • HMS Glasgow (1): Currently undergoing final outfitting at the Scotstoun yard. The ship was formally named in May 2025 and is on track for a 2028 service entry.
  • HMS Cardiff (2): Joined HMS Glasgow in the dry dock for outfitting.
  • HMS Belfast (3) & HMS Birmingham (4): Construction and block assembly are progressing, with modules being assembled inside the new Janet Harvey Hall.
  • HMS Sheffield (5): Steel was cut in December 2024, marking the start of its construction.
  • HMS Newcastle, Edinburgh, & London (6–8): Long-lead procurement is underway, with production scheduled to continue through the mid-2030s.
The Type 26 frigate is a high-end, anti-submarine warship with costs varying by nation and batch. The UK's Batch 1 costs roughly £1.31 billion per unit, with Batch 2 averaging just under £1 billion per unit. International projects are costlier due to technology transfer, with Canada’s 15-ship program estimated near C$70-80 billion, and Norway planning to acquire 5 for £10 billion.

....

Upcoming Type 26 Milestones
  • 2028: Expected Initial Operating Capability for HMS Glasgow.
  • Mid-2030s: All eight Type 26 frigates expected to be complete.
  • 2029: Expected delivery of the first Norwegian Type 26.

The Type 31 is a step up from the Rivers they will be replacing

I wonder if th RN is prioritzing the delvery of the Type 31s - more hulls faster for less.
 
"Kraken says it can deliver as many as 500 remote-controlled vessels in the current year and twice that in 2027, in part through deals with shipyards in places including Germany and the Pacific rim."

"Kraken now offers a range of drones, with the 8.5-metre Scout Medium currently arguably the most popular and easiest to mass-produce — but it will not say if any of its craft have so far seen action in the Middle East or the Black Sea."

"Such vessels can carry a range of weapons and other payloads, including surveillance cameras, machineguns or enough on-board explosives to sink a large ship."
