The Strategic Defence Review – setting out a path for the next decade and beyond to transform Defence – has been published.

The Strategic Defence Review (SDR)  signifies a landmark shift in deterrence and defence: moving to warfighting readiness to deter threats and strengthen security in the Euro-Atlantic.

The SDR’s vision for UK Defence:

  • Move to warfighting readiness — establishing a more lethal ‘integrated force’ equipped for the future, and strengthened homeland defence.
  • Engine for growth — driving jobs and prosperity through a new partnership with industry, radical procurement reforms and backing UK businesses.
  • ‘NATO first’ — stepping up on European security by leading in NATO, with strengthened nuclear, new tech and updated conventional capabilities.
  • UK innovation driven by lessons from Ukraine — harnessing drones, data and digital warfare to make our Armed Forces stronger and safer.
  • Whole-of-society approach — widening participation in national resilience, and renewing the Nation’s contract with those who serve.
