Is there any way to remove enemy mines other than using mine sweepers or throwing ships at them? Will 20 fighters in a group destroy 20 mines (and die)? If I have a ship that can sweep 100 mine fields, and we encounter a field with 100 mines, do all get swept, or is there some risk that some will go off? If I have a fleet at a wormhole and give them orders to return to a base and be mothballed, will they be mothballed at the base? Does the base need a shipyard?

Thanks!
