It is Armed Forces Day tomorrow, the culmination of a week of celebrations. During my visit to HMNB Clyde, I was asked what Armed Forces Day means to me. #HMNBClyde @ArmedForcesDay @RNinScotland @SDA_mod
81 years ago today, thousands of troops landed in France in the largest amphibious assault in history. I pause to honour all who enabled that maritime operation. Then as now, the Royal Navy stood strong - thank you to all who still do today, serving at home and around the world.

Inspired to meet the team from the RN, RM, Civil Service and DSTL at the Royal Navy Operational Advantage Centre showcasing our leading edge autonomous capabilities to protect the UK’s CNI and the security of our nation. @RoyalNavy @RoyalMarines

Good to talk to VAdm Mark Hammond Chief of Royal Australian Navy, and work with the Australian High Commissioner His Excellency The Honourable Stephen Smith on our shared endeavours. I’m looking forward to engaging with allies and partners as I begin my tenure as 1SL. #ausnavy
