The Royal Navy reported on 8 October that Zulu Squadron of its Mine and Threat Exploitation Group is preparing to use three autonomous mine-warfare technologies: Thales' mine-countermeasures system, TKMS's SeaCat medium uncrewed underwater vehicle and a Sweep Portable System that tows an acoustic target-signature emulator. The Navy says the squadron should have trained on and taken delivery of the equipment by the end of 2026. That is a stated near-term plan, not confirmation that the whole set has been accepted or deployed on operations.
Training and sea-trial status
According to the Navy, Zulu Unit 1 has spent much of 2026 in Plymouth training operators and maintainers for the Thales equipment. Unit 2 has trained with TKMS equipment in Weymouth. With those training phases finished, the units are moving into sea trials to validate procedures in representative conditions. The report does not give trial performance metrics, acceptance criteria, delivery dates for individual vehicles or the number of SeaCat systems assigned to the Royal Navy.
The Navy also describes separate activity by its X-Ray Squadron during Exercise Sea Breeze, including completion of a detect-classify-identify cycle on several contacts, two assessed as historic ordnance. This is not a reported live mine-neutralisation result for Zulu Squadron's incoming SeaCat or Thales equipment. The report describes other mine-warfare personnel aboard RFA Lyme Bay in the Middle East, but it should not be read as evidence that the complete new Zulu equipment set has reached that deployment.
The significance is a service-led transition from commercial off-the-shelf equipment toward purpose-built mine-warfare systems, with operator training and validation under way. Further evidence will be formal delivery or acceptance notices, system-specific sea-trial outcomes and documented operational tasking. SeaCat's existing library profile describes its modular underwater-vehicle design; the Navy's October account adds the UK training and planned handover context, not a new manufacturer performance claim.
