How to join the Royal Navy: the application process explained

A career in the Royal Navy can take you around the world, but getting in follows a clear, multi-stage process. This guide explains the Royal Navy application journey from first contact to starting training, including the Defence Aptitude Assessment (DAA), the Royal Navy Swim Test and the fitness assessment. The exact steps and standards vary by role and are updated over time, so always confirm the current details on the official careers site at royalnavy.mod.uk before applying.

Step 1: Register and apply

You begin by applying online through the Royal Navy careers website, choosing the role or branch you are interested in. There is a huge range of jobs at sea and ashore, from engineering and warfare to logistics, medical and aircrew, and each has its own requirements. A recruiter or careers office will usually be in touch to help you through the process once you have applied.

Step 2: Check your eligibility

Make sure you meet the basic entry criteria before going further. In general terms these cover:

• Age — there is a minimum joining age (commonly around 16) and an upper limit that depends on the role.
• Nationality and residency — requirements are tied to security vetting and depend on the role, including consideration of your background and close family.
• Health and fitness — you must be medically fit for naval service, and your body weight relative to height (BMI) is assessed within a healthy range for the demands of training.
• Swimming — everyone who joins the Royal Navy must be able to swim, as life at sea demands it.
• Qualifications — some branches ask for specific GCSEs or higher qualifications, while others have no formal academic entry requirement.

Because these vary by role and change over time, use the above as a general guide and confirm the specifics for your chosen branch on the official website.

Step 3: Sit the Defence Aptitude Assessment

Like the RAF, the Royal Navy uses the DAA as a core part of selection. It is a timed, multiple-choice aptitude test with six sections — verbal reasoning, numerical reasoning, work rate, spatial reasoning, mechanical comprehension and electrical comprehension — sat without a calculator. There is no single pass mark; your section scores help determine which branches you qualify for. Learn more in our Defence Aptitude Assessment explained guide and get ready with our practice tests.

Step 4: Interview and selection

Successful applicants are invited to an interview, which explores your motivation, your knowledge of the role and the Royal Navy, and your readiness for service life. Recruiters look for people who have genuinely researched what they are signing up for, so be ready to talk specifically about your chosen branch and why it appeals to you.

Step 5: The Royal Navy Swim Test

Because you will live and work at sea, the Royal Navy assesses your swimming before you join. A typical Swim Test involves entering the water at the deep end, treading water, swimming a set distance without stopping or touching the side, and climbing out of the pool unaided — often while wearing an issued set of overalls and completed within a time limit. You do not need to be a competitive swimmer, but you must be comfortable and capable in the water, so it is well worth practising in advance if you are rusty.

Step 6: The fitness test

You will also complete a Pre-Joining Fitness Test (PJFT), most commonly a timed 2.4km run, with the standard set by your age and gender. Some specialist branches, such as divers, have significantly tougher fitness standards and fixed times to beat regardless of age. Start your fitness preparation early and build up steadily rather than cramming close to the test date.

Step 7: Medical and eye test

A medical assessment, including an eye test, confirms you are fit for naval service. It reviews your medical history and general health, and certain conditions may affect eligibility or need further review. Being open and accurate about your history avoids complications later in the process.

Step 8: Security checks and offer

The Royal Navy carries out background and security checks, which can take time depending on the level of vetting your role requires. Once you have cleared every stage and confirmed you understand the terms of service, you will receive your joining instructions.

Step 9: Basic training

Your naval career starts with basic training, where you learn the fundamentals of service life — fitness, discipline, teamwork, seamanship and core military skills — before moving on to the specialist training for your chosen branch. It is demanding but designed to build you up progressively, and arriving already fit makes a real difference.

Preparing for success

The two things most in your control before you apply are your fitness and your DAA performance. Get comfortable in the pool, build up your running, and practise each DAA section under timed conditions. If you are still deciding between services, our guide on how to join the RAF covers the equivalent air force journey, which uses the same aptitude test.
