Changing CO/XO Tour Paradigm?

Word on the street is that the Submarine Force Flag Officers are going to be discussing (at an upcoming "Clambake") the desirability of changing the current model whereby a submarine officer serves as XO on a boat for less than 2 years, then goes to shore duty, thence to PCO training and then a 2-3 year CO tour on a different boat. They're looking at the SWO/Airdale model, where a guy goes through PCO training, then shows up as XO, does that for 18 months, then relieves the CO and stays in command for another 18 months. The theory is, I suppose, that this could help reduce the number of Class "A" mishaps.

What do you think? Assuming NR buys off, do you think this model could work in the Sub Force? Or should we stick with what we have, or go off in some other direction?
