Brief Description

As an Engineering Technician (Marine Engineering) (Submariner), you’re the driving force of the boat. It’s down to you to keep our submarines moving, deep below the surface. You’ll often be on highly sensitive operations, where avoiding detection is paramount. Without the power you provide, the vessel, and your crewmates, are stranded.

When you join, you complete 10 weeks of basic naval training, followed by 33 weeks of role-specific training, where you’ll learn how the machinery on a submarine works and how to repair and even make components. You’ll then receive further training on submarine equipment, before going to sea for the first time. At the end of this phase, you’ll sit an exam. If you pass, you’ll earn your Dolphins - the mark of a qualified Submariner – and join your crew

Future Prospects

  • Members of the Royal Navy are promoted on merit. Work hard and you can rise through the ranks

Vacancy Detail
