Shipping lanes and warships
 

Is there anysuch thing as a warship cruising lane? Big ones, like CV's and BB's. Sometimes I see a task force cruising up and down the coast between Rockall and the northern approaches, all the way down to the southern approaches. But theyre fast and I never see them.

I don't think so. Warships usually have a specific goal rather than cruising between A and B, like merchants do.
