Submarine Equipment Life Extension

Replace Existing Systems


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 Equipment 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.
