Possum, being a cheapskate, doesn't have the sim yet. He needs to get it ASAP. Until he does, he's referencing real world vice DCS.
Yes, fuel is always a balance depending upon whether you have a bingo field in range, what the Airwing policy happens to be, and the mission. Ashore, once you had the gear down for the first pass, then you'd likely do touch and goes until you had a low fuel light. The point being that you didn't need to save fuel to troubleshoot a possible gear issue once you were fully configured.
As stated before, we left the gear and flaps down between landings (unless diverting, etc).
We flew a lot more than USAF (and way, way more than our adversaries) did when I was on active duty. I don't know what's going on now, but some of the USAF numbers I hear from recently separated Zoomies are appallingly low. I see why they are unhappy.
Possum is about two decades younger than I, so he can bring you up to speed on what came later, but it is probably true that USN spent a lot of OPTAR doing landings. In my day, we still probably flew more tactics than USAF.
The French Navy pilots by the way, all flew exactly the same number of hours, with only LCDR (equivalents) allowed to land on the ship at night. They got more hours than the daytime only Junior Officers. We in contrast, were always fighting for more time. Some of the married guys wanted to go home at night, while we bachelors snarfed their flying. ;)
