Question to the Ministry of Defence:

To ask the Secretary of State for Defence, with reference to his Department's press release entitled 20,000 UK jobs secured as Türkiye buys 20 Typhoon jets in biggest fighter jet deal in a generation, published on 27 October 2025, when he plans to place a contract for a Phase 4 Enhancement electronics upgrade.

The Phase 4 Enhancement capability package (P4E) is an essential enabler for the implementation of the next generation radar enhancement for the UK's Typhoon fleet.

The System Definition Contract for P4E was signed in June 2024 and since then the UK, Germany, Spain and Italy have been working closely alongside NETMA and our industry partners to agree on the final P4E capability package, which will then move into the Design, Development and Demonstration phase.

Additionally, the Core Nations have agreed to begin early design work on long lead activities, ensuring that critical path activities for P4E capability are protected. The delivery of the P4E package is planned to take place by the end of this decade.
