High technology

A method for technological levels:.  One way to provide for lower and
higher
tech levels might be to play with the mass a system requires at a given
tech
level with older systems being more massive for the same result and
newer
systems being less massive.  To maintain play balance charge more points
per mass for newer systems.

With this as a given at what size would stike boats become heavy
fighters
and could one make FTL fighters.
