Some of us older guys have said it often before, but it's worth keeping in mind: it doesn't matter how good you are in the plane. Sure, it doesn't hurt to be a good stick or tactically proficient, but it is far from the most important factor. And in some communities, some of the "best" qualifications are reserved for the chosen ones, so they won't always be a good indicator of which guy is the best in the cockpit (or tube, as the case may be).
This is true - in our community, stick skills are secondary. There is value, I believe, in doing other things outside the plane. As much as I hated being sent to Japan, I did learn a lot about the big navy and my "expertise" in the plane was directly injected into the tactics developed for several plans. I'd like to think that my operational experience and input made the plans better - certainly a lot of people bought off on the plans... If you don't have people who have operated going to fill jobs developing plans, policy, and strategy, then you're going to get crappy plans, poor policy, and ineffective strategies. You wouldn't want me as a P-3 guy planning TacAir missions, and you don't want a TacAir guy planning ASW, or a SWO planning anything.
Since I was "sent forward" (P-3 skipper double speak, trying to make it sound like a good deal), and since I went to another shore tour after that on a different staff, my skills in the plane have atrophied significantly. The planning I do now in a joint billet is completely unrelated to ASW or anything MPRA - though occasionally I do get asked a question about ASW. I'm not sure there is a huge amount of value to the P-3 community with me going to a joint job as a JO, but I didn't take this job for the community's sake. Joint is directed by law, however, so eventually an officer will have to learn how to speak Army and Air Force to help integrate the Navy's capabilities into a seamless operation (in theory). This is a good thing, though painful.
I'd still like to see a program that allows officers to stay in the plane for as long as they would like, achieving a level of expertise not seen today. This is how they do it in Australia, where you can choose to stay operational your whole career, but you won't make it past O-3 or O-4 - but that's OK. If you want to be a skipper or higher still, you need to do the same staff crap we do. Of course, this would probably reduce the pool of P-3 officers going into the higher ranks and there is something to be said about having a community specific presence at higher levels to protect your platform.
