   Els - do I understand correctly that your analysis are for coilgun that has   
   just one coil? I am completely ok with multiple coils accelerating projectile   
   on these 25 meters. Also, the width of projectile is 5 cm, not 10cm. I am   
   thinking what would be    
   better than iron in making it, something that could resist more heat. What do   
   you think?    
   I think I have missed exactly this equation you say, although I am not sure if   
   I just didn't put super high Tesla field and efficiency in it. It depresses me   
   that you say the high speed coilguns wouldn't make sense, because in my   
   settings lasers are    
   pretty uncommon and unreliable weapons. :(    
   How about helical coilgun? Would it make any diferrence?    
   Mr Feergerson - After reading about space fighters on Atomic Rockets, I came   
   up with justification for them in my setting. So, as you know, the outer   
   planets are trying to fight Arda and Loyalist worlds. Making a normal, big   
   ships could be a bad idea,    
   because they could afford just a few of these probably. So, they start making   
   small "space fighter" like vehicles, that give them advantage of having   
   multiple angles of attack on the Arda ships. So, Ardans, to counter it, make   
   their own fighters, with a    
   purpose of destroying the rebels before they get to the positions. Also,   
   fighters can serve as additional platforms for orbital bombardment, and, if   
   they can fly in atmosphere, aerial superiority and ground attack. What do you   
   think?
