Chief of Defence Nuclear

Great to welcome @UKCDS_MOD to Barrow last week. A valuable opportunity to see the incredible work happening across the yard and meet the teams driving forward our National Endeavour.

A proud moment for AUKUS as HMS Anson completes her Submarine Maintenance Period in Australia. The skills, trust, and relationships built here have strengthened the foundations on which the next 125 years of collaboration will be built.

This #BritishScienceWeek is a reminder that Defence Nuclear offers rewarding careers working on some of the most challenging and important problems facing our nation. #BSW26

This #NationalApprenticeshipWeek, we celebrate the thousands of apprentices developing the specialist skills our Defence Nuclear Enterprise depends on. Your talent is building the UK's future nuclear workforce and strengthening a vital national endeavour. #NAW2026

Maintaining our submarines is a top priority for the DNE. Great to visit @HMNBClyde with @GenGJenkinsRM to see firsthand the teams driving a rapid, sustainable boost in maintenance output. Their work is critical to keeping the Fleet ready. #OneClyde

Congratulations to the @HMSOardacious crew on completing the World's Toughest Row. The Atlantic crossing raises vital funds for @RNRMC, supporting mental health and wellbeing for serving personnel and their families. An extraordinary achievement in the most demanding conditions.

In Oct 2025, King Charles III visited @BAESystemsplc in Barrow-in-Furness to mark the commissioning of the UK’s newest Astute-class submarine. Thousands at BAE are shaping the future of nuclear tech and innovation. Explore roles: destinationnuclear.com #DestinationNuclear

Excellent to see Team Plymouth showcasing their defence growth plans at Westminster. The £4.4bn investment in Devonport will enhance our submarine maintenance capability whilst driving regional growth - vital for the DNE and the communities that support our #NationalEndeavour

The #DNE has a growing demand for nuclear skills, providing new and exciting opportunities across the country. Find out what the nuclear sector has for you https://www.destinationn uclear.com/quiz

In solemn remembrance of the submariners who have given their lives in the service of our nation. Your courage, sacrifice + silent vigilance will never be forgotten. On behalf of the Defence Nuclear Enterprise, we honour your legacy and stand in gratitude.

A proud moment for the DNE! 👏 HMS Agamemnon successfully completed her first under water dive @BAEsystemplc in Barrow - a major milestone for everyone involved

Fascinating visit to our joint UK-France facility (EPURE) in Valduc together @TomDrewUK where cutting-edge technology is being used in hydrodynamic trials for the benefit of each of our programmes. An outstanding example of close collaboration by Europe’s two nuclear powers.
