   Okay, let's change a few things, I messed it up a bit. The engagements start   
   at a few thousand kilometers, but there the fight goes with lasers, missiles   
   and PBWs, and at a few hundred kilos (let's say 300km) the coilguns are used.   
   I didn't hear about    
   this Russian experiment, although I knew that they were working on   
   electromagnetic guns. 2 grams at 5 km/s would probably be at firearm range of   
   energy, am I right?    
   My ships (they are for my setting) are around 700 m long, shape is most   
   closely represented by cuboid (hope dictionary is correct :p), they can   
   withstand high acceleration in line with main engines thrust direction and up   
   to 2,5 Gs left/right/up/down (I    
   know there was a better term for that, but I don't remember it), although   
   normally their manevuering thrusters go at 1G max, to not stress the   
   structure. As for armor, whole ship is covered in anti - laser something, and   
   important areas are in armored    
   belts of whipple shields, and here I don't know much about how to calculate   
   optimum thickness and mass of them, were there any studies?    
   Also, how fast blue laser dissiapate in vacuum?    
   And finally, have you got Quora account? Just today I have seen someone with   
   your name answering sfnal weapon question :D
