I agree that it's nice to have full evolutionary trees for different ship classes. I just think FM 2765 CCAF is not the best place to do that for the TA/TH. That would be something that a FM: The Age of War could do (*hint, hint*). As it stands now we have a rather large number of shiptypes for TA/TH/SL providing classes for nearly every occasion and in any desired flavour yet when it comes to the houses the list of known ship classes is depressingly short (at least IMO). I would like to see full-blown sets of domestic WarShips for all of the great houses because if they don't have them i start wonder why the TA/TH/SL kept on churning out new classes when there was basically no opponent to fight.
It's not exactly unprecedented, though - Historical: Reunification War gives us a ship listing for the AFFS fleet destroyed during Case Amber, which represented "over half of House Davion's WarShip fleet"; that fleet breaks down to the following WarShips:
3 Aegis-class cruisers
3 Congress-class frigates
7 Robinson-class transports
5 New Syrtis-class carriers
5 Baron-class destroyers
9 Davion II-class destroyer
7 Davion I-class destroyer
10 Vigilant-class corvettes
10 Vincent Mk. 39-class corvettes
So, of the 59 WarShips present, 31 were domestically produced and 28 were former Hegemony vessels. It may well be that during the Age of War, none of the House economies and technology bases were capable of producing a full range of WarShips for themselves - the Hegemony had a head start after all, while the Houses were busy fighting various internal wars of formation and building their bases up before then attacking each other.
