Ghostie,
I'll leave the Navy guys to answer your questions in detail, but I'll hazard a guess as to why you haven't seen Navy fliers complaining on here:
1. The FAA is a much smaller outfit than the RAF => fewer people overall means fewer people unhappy (even if the percentage of unhappy people is the same as or higher than the RAF) => fewer moans on here.
2. The Navy have always spent a lot of time away from home, whereas for the RAF this is a relatively new development (Desert Shield/Storm was the beginning of it, but the major increase in op tempo was only 6 years ago); being away from home is by no means the only gripe RAF people have, but when compounded by all the other issues which people face, it adds up. The Navy, by comparison, are more used to being away - and I would guess that being on a ship would cocoon people from a lot of the nuisance of military life (Stn Cdr's training days? JPA?)
3. Bear in mind that plenty of people (well, some!) in the RAF are quite content with their lot, but those people are reluctant to write posts going on about what a great life they have out of respect for those colleagues of ours who are getting the ****ty end of the stick!
Notwithstanding the above, there may well be something that the Navy is doing right which the RAF could learn from - please tell us, o Senior Service stoics!
