This is correct. Fred's design unfortunately doesn't work as written, but could be fixed with fusion rockets.

Unrelated, when adjusting combat range downward, I might just do that automatically after 10 rounds even if ships have managed to inflict *some* damage on each other. That way, having weapons with Extreme range is worthwhile, but you avoid the thing where it's literally impossible for ships with less than 0.5G acceleration to close on each other after well over an hour.
