Captain Sand Dune: good point however there are many reasons why each force operate there own aircraft. Take for example a Seahawk pilot. Although he/she flies the machine, he/she is primarily firstly a Naval Officer. Generally has completed not only their aviation training, but some seamanship training (in many instances have a Bridge Watch Keeping Certificate), Naval Officer training, all the requirements to go to sea (eg NBCD, Helo and ship escape training etc). It takes a long time to get someone to the point where they are trained to fly off an FFG or an Anzac and be truely part of the team!! Its more than just talking the talk and walking the walk!! The Air Department is just one department on a ship with each relying on the other!!
I remember once chatting to the Captain of HMAS Onslow (now retired submarine) and it was in his opinion that it was harder to avoid detection by a RAN Tracker than a RAAF P3B because the Tracker Crew were taught to think like submariners.
