Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what approvals process is required for the Merlin Out of Service Date Extension Programme; and what the timescale is for that process.

The Royal Navy’s Merlin helicopter Out-of-Service Date Extension Programme, to retain the capability in service from 2029-30 until 2040, is currently underway through standard Ministry of Defence processes. The Outline Business Case was approved in October 2023. A Review Note was approved in December 2024. Departmental Spend Control Approvals are currently considering whether to commit expenditure for this Programme in 2025-26. The forecast for a Full Business Case submission is in early 2027.
