so we need to determine what is a good number required to form a ring around all your primary warships
+++++ Its not only that… it was the idea that a sub could not get a clear shot and also to have a forward, rearguard and laterel defense to search for U-boats.
Thats why if a cruiser or destroyer is present the subs premtive strike is negated.
maybe the OOB rule of letting your submarine-attack casualities fire back is not realistic
in fact, should submarines fire in opening-fire?
++++ yes if you have no supporting ASW warships.
if so, should an early warning from friendly DD actually let you fire back?
++++ for who? the player with the subs? or the player who owns the ships?
destroyers are guranteed a chance to hit back…is that realistic?
++++ well the subs can still sink a ship… only that it now gets a parting shot… ok i think i see what you mean… you want to allow the sub to still maintain its premtive shot, but then also allow any destroyer/ cruiser the ability to then search and attack the sub under ASW ideas?
