So I've just finished a major rebuild of the Constitution class... What next? The next step is to knock out a couple variations on the same essential hull configuration. Those include the
Andromeda, Apollo, Kirov, Slava, maybe one or two others.

Edit: So lets see...
1. Add the upper Nacelle to make an Andromeda
2. Lower the side Nacelles to make the Slava.
3. Remove the upper Nacelle to make a Kirov
4. Remove the secondary hull from the Slava to make a Carlson
5. Something like that. I may be tired of this series by then...
I also have some TMP era Miranda variants that are about 90% complete. None of these are new projects, but a squadron of new ships for the effort of a few nacelles is hard to pass up.
