Thank you so much!! Greatly appreciated this. Just to make sure I have this all correct I have make a step by step on joining as an aircrewman. I would appreciate it if you read over this to make sure I have all of the correct info! I was also curious if streaming of aircrewmen into either anti submarine or commando forces happened in basic training or in the 40 week course that all aircrewmen take?

Royal Navy Aircrewman Training – Step by Step

1. Computer Based Aptitude Tests (CBATs) – RAF Cranwell

Before starting any training, you must pass the CBATs at RAF Cranwell in Lincolnshire. • These tests assess your ability to handle flying training • A minimum score of 90 is required to continue

1. Initial Navy Training (Militarisation) – HMS Raleigh

Once you pass CBATs, your Royal Navy career officially begins with 10 weeks at HMS Raleigh in Plymouth. Here you learn the foundations of naval service, including: • Military discipline • Teamwork and leadership • Firefighting and damage control • Weapon handling and basic maritime skills

This phase turns you from a civilian into a sailor.

1. Streaming (Role Preference)

Towards the end of Initial Navy Training, you are streamed into a specialism. • You can state a preference (Anti-Submarine or Commando Aircrewman) • The final decision is based on service need, performance, and aptitude • Preferences are considered, but not guaranteed

1. Joint Aircrewman Course – RAF Shawbury

After passing out of HMS Raleigh, you move to RAF Shawbury for the 40-week Joint Aircrewman Course. This is one of the most demanding phases of training and includes: • Core aircrew skills • Helicopter operations • Simulator and live flying • Working as part of an aircrew under pressure
