Hi All,
I've just seen this thread and thought I would add some information for you. Following on from a recent RJP @RAF Shawbury. You will likely be streamed into either ATC (School of Air Ops Control) based at Shawbury or Weapons Control (School of Aerospace Battle Management) at RAF Boulmer following graduation from IOT. Both will start with a 3 week common air ops course, following completion you will go to JATCC (Joint Air Traffic Controllers Course) for ATC or WCC (Weapons Controller Course) at Boulmer which are both 22 weeks in length.
This is all subject to change, due to the recent amalgamation of roles. But at the moment, Air Ops Control is being heavilly recruited to my knowledge. And by the looks of it the RAF are addressing the time at which you will be streamed.
Hope this Helps
