How the Royal Navy is developing extra-large uncrewed submarines

Would Britain respond to a larger threat by mass-building conventional submarines or other undersea craft?

Its extra-large uncrewed underwater vehicle program could move from iterative testing to rapid batch construction and forward deployment.

The Royal Navy is building and testing successive long-range underwater uncrewed vehicles before committing to a major production design. Each prototype carries lessons into the next hull while preserving a continuing construction base. That sequence appears to prepare for rapid batch production once a threat makes numbers urgent. Such craft could then be forward-deployed around the Falklands without recreating a large fleet of crewed conventional submarines.
