To act as a capability sustainment and enhancement project designed to extend the service life of the Victoria-class submarine beyond its current mid-2020s end of life.


Re-activation of the Upholder-class submarines (renamed Victoria-class), as part of the Submarine Capability Life Extension Project, included a reassessment of their in-service life expectancy that resulted in a predicted end-of-service in the mid-2020s. The Submarine Life Extension (SELEX) Project will maintain the safety and serviceability of the "Float" components of the Victoria-class. It will maintain and, where appropriate, improve operational capabilities in both the "Move" and “Fight” components of the Victoria-class. A detailed scoping study has been completed and the recommendations of that activity will be used to define the exact scope of the SELEX Project.
