Question to the Ministry of Defence:

To ask the Secretary of State for Defence, with reference to the Answer of 20 April 2026 to Question 125978, what metrics his Department is using to assess the effectiveness of the learn and adapt cycle referenced in relation to lessons from Ukraine; and how frequently these assessments are reviewed by Ministers.

His Majesty’s Government continually monitors and assesses the threats to the United Kingdom.

Ukraine is demonstrating that the pace of the ‘learn and adapt’ cycle has accelerated exponentially. Capability concepts through acquisition to employment to countermeasures can now take weeks, if not months. Defence’s lessons governance mechanism provides interpretation of lessons and how they relate to the UK and identifies pathways for remedial action. Our relationship with Ukraine has allowed the UK to continually improve this approach.
