   Yes. the initial assumption was that the locations of the platforms were   
   known. This was followed by the suggestion that a slow repositioning will   
   prevent them from being destroyed. This assumes that the target is not going   
   to be where the attack hits,    
   which means either the target "dodged the bullet" by moving out of the way   
   faster than the attack could respond, or that the attack would be unaware of   
   the change in position. The slowness of light sails means that the array would   
   not be able to simply "   
   dodge the bullet"... not when the "bullet" is capable of course correction.   
   Using a light sail means that "not being there" is not going to work either,   
   because you are hanging up a sign saying "please track me".

   Invalid assumption. Careful planning is much more useful.

   The constant g? No, not at all. Constant manoeuvering using the "oh shit"   
   rockets to try to evade the TRACKING kill squad, however, will. Do not assume   
   that there will be a single warhead, and do not assume that someone is going   
   to just use a sniper    
   rifle... this is going to be a fleet of kill drones.

   Wrong. Military operations NEVER assume that all detectors have been   
   dispatched from service. Military engagements don't require an enemy to be   
   blind... but they WILL blind the enemy as much as possible to make responding   
   more difficult.

   Yes. Which is why strategic planners allow for contingencies. Sensor targeting   
   is NOT a one-time-only operation.   
   And, yes, I myself have pointed out subterfuge as stealth. Honestly, the   
   attacker will probably never have to launch most of those kill drones, because   
   they will already have used subterfuge to arrange premature deaths for those   
   platforms... or methods    
   for disinformation (why destroy a useful asset if you can hack it instead?).

   Yes it is... until you have everything htting at once. You have very long   
   pause intervals where nothing happens, and then a few minutes or hours of pure   
   adrenaline rush.

   Depends upon what you are hitting with... and what it looks like. Yes, they   
   will probably be seen, but there is always the question of if they will be   
   recognised for what they are. The Japanese fleet was spotted long before   
   hitting Pearl Harbor. Just    
   imagine if those zeros weren't mistaken for a training flight.   
   Yes, there will be an ongoing attempt to field new sensors throughout the war.   
   There will also be ongoing drives to knock them out of service. As I said, it   
   is not a one-time-only deal.

   There is actually quite a lot that can be concealed... if you know how.
