True, but weapons, especially kinetic energy weapons, want to do the opposite of "matching speed and position". They just need to attempt to occupy the same point in space at the same time as the target. There are literally an infinite number of possible orbits that would do that. Matching speed and position of the target is the last thing you would want to do with a kinetic energy weapon. It is the matching speed and position that takes all the time.psCargile wrote: Even while traveling 17,500 miles per hour in low Earth orbit, getting to the ISS ( International Space Station )takes a few days of maneuvering using phasing orbits to match the speed and position of the target.
Physics determine what happens when two objects traveling at very high relative rates of speed attempt to occupy the same space at the same time. The result is the same, even if one of the objects is very small.
