How about implementing a cost reduction bonus based on production numbers so that older designs can be put to good use?
This could create an interesting real-world industrial/economic-like dynamic, as people would be able to choose between expensive but performance-driven modern designs and inexpensive, reliable older designs.
From a gameplay perspective, it would be desirable to have a choice for players who have scarce funds but need a ship too.
It would also be good to get a sense of typical space opera elements. (Kind of like the YT series, TIE fighters, and Y-wings in Star Wars)
