What you’ll do

As a Marine Engineer Officer (Submariner), it’s your job to lead a highly trained team in some of the most challenging conditions imaginable. Working on a submarine isn’t for everyone. That’s what makes you, and your team, elite.

Being a Submariner Engineer Officer means overseeing the maintenance and operation of a nuclear reactor. It’s a role that comes with huge responsibility, because without you the boat is stranded, and some top secret missions don’t happen. You’ll push your engineering knowledge to the limit, as you find solutions to complex problems, and work with the most advanced kit imaginable.

Starting your career

Joining process

Once you’ve confirmed your eligibility, the joining process is as follows:

  • Submit an application

    Once you’ve registered your interest, we’ll be in touch to discuss your options

  • Defence Aptitude Assessment (DAA)

    You’ll be tested on: Verbal Reasoning, Numerical Reasoning, Work Rate, Spatial Reasoning, Electrical Comprehension and Mechanical Comprehension.
    To prepare, you can practise the DAA

  • Interview

     A formal interview to talk through your suitability for the role

  • Medical and eye tests

    These are quite comprehensive and must be completed by one of our Ministry of Defence-approved doctors

  • Pre-Joining Fitness Test (PJFT)

    This involves completing a 2.4km run on a treadmill within a certain time, at a fitness centre near you

  • Interview

    You’ll have a short interview to assess your suitability for a career in the Royal Navy, and to ensure you’re ready for the Admiralty Interview Board (AIB)

  • Admiralty Interview Board (AIB)

    This stage is unique to officers and takes place in two parts. A Pre Recorded Interview (PRI) is an online assessment which assesses your motivation to join the Royal Navy as an officer and your awareness of the Royal Navy. The Group Planning Exercise (GPE) is the second stage of the AIB and is an online competency based assessment which will take place on a separate day to the PRI. It will be conducted in a virtual group environment and you will be assessed on your contribution to the team based on your individual performance


Initial training

You’ll spend 30 weeks training at Britannia Royal Naval College (BRNC) in Dartmouth, focusing on: military skills, maritime skills and initial fleet time. The military skills phase includes learning leadership and teamwork skills, and the principles of command and management. You will put this into practice during several exercises on Dartmoor.

Aim to get yourself as fit as you can before you arrive. You’ll be doing a lot of physical exercise, and you’ll find it much easier if you’re already in good shape.

There's also a swimming test, so if you can't swim, make sure you learn by the time you join us.


Professional training

Your professional training starts with a 10-month systems engineering and management course, focussing on:

  • Learning about gas turbines, diesel generators, hydraulics and air systems
  • In-depth study of avionics, engines and weapon systems
  • Managing an engineering department
  • Maintaining and operating a nuclear reactor, resulting in Diploma in Nuclear Reactor Technology 
  • Learning about all the systems on board a submarine, from warfare and weapons, to propulsion

After successfully completing your professional training, you will stay another four months at HMS Raleigh in the Submarine School. You’ll learn about submarine operations, including warfare, weapons, nuclear propulsion and escape training, and go to sea in a submarine. After this, there’ll be a test to check your knowledge. When you pass, you’ll earn your ‘Dolphins’ – the coveted badge of a qualified Submariner.

Once you’ve refined your skills, you’ll take your place on board an active submarine, where you’ll lead a team of engineers on deployments all over the world.
