Yep. The Age of Sail provides the only reasonable model for Traveller interstellar warfare. Fleet commanders have tremendous autonomy, because they need it; once away from bases, their information will be at least a week fresher than HQ's, and that number increases the farther the fleet moves from the nearest base.
I once had fun trying to imagine what tactical and strategic planning maps might look like in Traveller. You'd have to label every asset with the time at which it was known to be at that location, and then have secondary versions of that asset spread across all the places it could be now, weighted by probability. I was picturing color coding -- yellow/orange/red for increasingly old intel about the enemy, violet/blue/green for increasingly old intel about friendlies. Add on notations for where friendlies are supposed to be headed in the future, where enemies are predicted to be going, and your own alternatives, and you get a map that's trying to display about nine dimensions of data in two or three dimensions of display. :) I'm sure that learning to read and use such displays takes up a fair amount of time in Naval officer training.
