@Baron:
Gives +1 Move to any surface vessel (TP, DD, CVE, CV, BB) paired 1:1 with
This is an interesting idea. One adjustment I’d make, however, is to limit the accompanying surface ship +1 movement boost to just destroyers. A cruiser shouldn’t be able be able to boost the movement of a ship that’s bigger than a cruiser, so that leaves out carriers and battleships. Cruisers don’t need to boost cruisers because cruisers have the boost already built into them. A cruiser boosting a destroyer sounds fine: destroyers are smaller, and the “boost” could represent the cruiser and the accompanying destroyer operating as a small task force or task group, with the cruiser as the lead ship and with the cruiser topping up the fuel tanks of the destroyer from time to time (as was indeed done during the war). A cruiser shouldn’t be able to boost a transport ship’s movement: many transport ships are quite large – some larger than a cruiser – and most transport ships are relatively slow, so they have no speed to gain from operating alongside a cruiser. (It’s actually the cruiser that would be slowed by the transport ship.) And transport ships would typically have a long range already, in part because in WWII they tended to use old-fashioned, low-powered triple-expansion steam engines rather than turbines.
Except for the destroyer, the only ship that could realistically gain a movement boost from operating in tandem with a cruiser would be a submarine, owing to its small size. In practice, though, I don’t think that subs in WWII operated in tandem with cruisers very much, if at all.
