Hi! I guess I should probably start by introducing myself. My name is Tom, I'm 19 and currently training to be a Merchant Navy Officer. I had always wanted to join the Royal Navy as an officer but when the SDSR came along, the Royal Navy's future seemed very uncertain so I decided to go away and get some life experience and see how it all looks in a few years time. In my quest to find something a bit different to university I found the Merchant Navy Cadet scheme and have dived straight in. A 5 months of navigation training and 4 months of sea time later and I'm loving it but still think I'd like to go for the Royal Navy after I finish my course in a couple of years time.Anyway one of the jobs I'm considering is becoming a Warfare Officer (Submariner) and was wondering how long the average tour of duty is? I was told not more than 3 months by a careers officer a couple of years ago but then have been assured by other serving RN Officers that it's much longer. Any chance anyone could shed some light on this for me?
