re: My concept.
Two questions, what would be the advantage of launching them ten years apart instead of simultaneously. One would think the more initial resources the colonists arrived with, the more robust the colony would be.
Second, Wouldn't it be difficult to launch ten identical ships over a century, there would be technical progress in both propulsion and cargo during the intervals, and it would be very difficult to send out the last ship, for example, with century-old gear.
What if the advance in propulsion systems was such that the last ship launched actually arrived ahead of some of the others.?
