Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what recent steps he has taken to protect British waters from infiltration by the Russian spy vessel Yantar.

The Royal Navy constantly monitors threats to UK waters, and we are ready and willing to respond if required. The YANTAR’s most recent incursion into British waters was met with a robust response, using capabilities from across the full spectrum of Defence.

The Royal Navy and Royal Air Force deployed HMS SOMERSET and RAF P-8 Maritime Patrol Aircraft to monitor the YANTAR’s every move within the UK’s Exclusive Economic Zone (EEZ). In addition, the Defence Secretary took steps to alter and enhance the Royal Navy’s posture to ensure we can better track and respond to threats from YANTAR or any other spy ship.

As the Strategic Defence Review underlined, the protection of Critical Underwater Infrastructure is a priority for Defence. We have invested in new capabilities to ensure our Critical Underwater Infrastructure remains resilient, such as the Multi-Role Ocean Surveillance (MROS) programme, which includes RFA PROTEUS. We also will continue to invest in our international partnerships and alliances, including NATO, to coordinate surveillance of the threat, expose those who seek to threaten us and hold them accountable.
