He has extensive combat experience having flown hundreds of operational missions from both land bases and aircraft carriers over: Bosnia; Kosovo; Serbia; Iraq; and Afghanistan.

In 2020, Smyth then became UK MOD’s inaugural Director Space, setting the foundation for UK Space Command, building the Defence Space Programme, and producing UK’s foundational National and Defence Space Strategies.

Smyth was promoted to Air Marshal (3*) in 2022 and appointed as the RAF’s Deputy Commander (Operations): this role transitioned to become the UK Air and Space Commander in 2023 and was responsible for all RAF’s air and space operations globally.

In Apr 24 Smyth became the first RAF officer to hold the role of Deputy Chief of Defence Staff (Military Strategy and Operations - DCDS (MSO)), responsible for the provision of military advice to senior leadership across government including the Prime Minister, the development of UK military strategy and its integration with partners across government and allies, and the commissioning of UK military operations at home and across the globe. During this tour Smyth was a routine member of COBR and the National Security Council.
