How do I become a Submariner in the Royal Navy?
If you are giving this any kind of serious consideration the best thing you can do is visit a recruiter. Submariners cover most of the trades and roles in the Royal Navy, from Warfare Officer to Cook. You have to be one of the stronger candidates to get on submarines. You would need to get through some pretty heavy duty vetting, especially for Vanguard class subs that carry our nuclear deterrent. Britain’s subs are currently an all male zone, so if you are a woman forget it. A policy change would require new subs or a serious redesign in dry dock. The government won’t be able to afford that for a few years at least. The actual mechanics of becoming a submariner is to apply to join the Royal Navy in one of the roles that serves on subs such as ‘Engineering Technician (Marine Engineering Submariner)’ or ‘Warfare Officer (Submariner)’. They then decide whether to accept you and if accepted you ship off to a some cold corner of the British Isles for a while to train, and then get sent off
