Question to the Ministry of Defence:

To ask the Secretary of State for Defence, pursuant to the answer of 20 April 2026 to question 125513 on F-35 Aircraft: Procurement, by when does he plan to have completed the Block 4 upgrade programme.

I have nothing to add to the answer I gave the hon. Member on 20 April 2026 to Question 125513:

We do not routinely comment on detailed delivery schedules. However, the Block 4 upgrade programme continues, it did not impact the declaration of Lightning Full Operating Capability. The Block 4 upgrade programme will further develop our world leading Combat Air capability, the UK Lightning, through improvements in lethality, survivability and supportability.
