We have never asked Lockheed Martin to postpone the completion date for JSF. We have not even declared an In Service Date for this programme in the UK and will only do so when the programme is sufficiently mature. We are one of nine participant nations in the JSF programme and its completion date cannot be determined by one participant in isolation.
We will not be setting in-service dates for the Joint Combat Aircraft (JCA) until we take the main investment decision, and we will take that decision when the project is sufficiently mature. The Joint Strike Fighter remains our preferred solution to meet the JCA requirement and our current plans for JCA remain coherent with the CVF programme.
