   How about the accompanying enormous magnetic field pulses? As far as I know   
   there's only one way to hide those, by allowing them to induce eddy currents   
   in a (thick!)    
   conductive shield, and the shield effect can't cover the muzzle. The pulses   
   will be easily detectable a long way off at light speed. Also, the eddy   
   current energy dissipates as heat putting more load on the cooling function of   
   the shroud.   
      
   Quick question, here: how are you detecting those magnetic field pulses? As I   
   understand it, you can't detect those fields directly unless you happen to be   
   IN the field itself. Indirectly, you need to detect something either radiating   
   FROM the field, or    
   you have to track something as it passes through the field.   
      
   Also, whereas you are correct that you can not cover the muzzle, you CAN    
   erect a "flash suppressor" AROUND the muzzle, so that you do not see the   
   muzzle unless you are in the immediate path (bad place to be). Thus, you can   
   not see in which direction it    
   is shooting.
