   Which gets you either a diffuse shot that probably won't do anything or a   
   narrow one that will probably miss.   
      
   (Not that getting this kind of even distribution is exactly easy.)

   And it's still really hard to hit because of the long time in flight and   
   the need for information which is impossible to have because it doesn't   
   exist yet.

   He flat out made the argument "you can't hide the sensor platforms   
   either."  It is 100% relevant to respond to that by pointing out that I   
   was not making an argument based on hiding the sensor platforms.

   They aren't anywhere near as tight as you seem to think, (given that you   
   have now revealed that you think a 100km wide attack is almost certain to   
   hit).

   Spotting the launching of a large, coordinated, attack is a lot easier   
   than compromising a important and highly redundant system.  To use an   
   analogy:  I'm trying to spot when your ship leaves harbour while you are   
   trying to get a saboteur into each of my coastal forts.

   You are misunderstanding the adage.

   False.  Even most of the small arms had been replaced by new designs.

   Those ships haven't gone a generation without systems upgrades.   
      
   They also don't have a crew that's a generation out of date, (although   
   you can get around that in space war).

   IOW:  You'll have nice bright radiators.
