Approved Cost

Approved In-service Date


£1996 million



£634 million

Project MENSA received a revised approval to its cost and in-service date in February 2022 reflecting, inter alia, the impacts of COVID-19 and amendments to the project to support the future warhead programme.

All outstanding infrastructure related projects at AWE are still subject to internal departmental approval processes and approved outturn cost and in-service dates are not yet available.
