   Let's say a torch missile (or anything) is on an intercept trajectory towards   
   a target.   
   If the target makes a burn to counter, would it necessary take the same amount   
   of delta-v for the missile to keep the intercept?   
      
   I suspect that it's a tradeoff between efficiency of plane changes and oberth   
   effect gains.
