Not enough google-fu, maybe.
COGAG is sometimes used to mean that a ship has two different models of gas turbine for cruising and sprinting. The Arleigh Burkes have four turbines, all the same model, but I bet they can declutch one from each shaft. The engine manufacturer describes the ABs as COGAG: http://www.geaviation.com/press/marine/marine_19980225.html John _______________________________________________ GurpsNet-L mailing list <[email protected]> http://mail.sjgames.com/mailman/listinfo/gurpsnet-l
