Technical Readout: 3057 Revised indicates in the description of the Texas-class battleship on page 160 that only 7 of the 52 Texas class vessels constructed survived the Hegemony Campaign and departed with General Aleksandr Kerensky on the Exodus, and that 2 of those 7 were destroyed during the Exodus civil war.
Between the various sourcebooks published to date, it appears that the 7 Texas-class vessels that survived have all been identified:
SLS Perth - boarded and captured by Absalom Truscott's forces above Arcadia during Op KLONDIKE (Historical: Op KLONDIKE)
SLS Prinz Eugen - stored in a naval cache and unclaimed by any of the Clans as late as Op REVIVAL (The Clans: Warriors of Kerensky, plus later sourcebooks like Wars of Reaving)
SLS Bismark - pulled out of the Norfolk cache in the Strana Mechty system, vanished along with Khan Trish Ebon and her group of Clan Wolverine survivors after the battles at Barbados (Betrayal of Ideals)
CCS Ancestral Home - adopted by Clan Coyote, garrison ship for Tamaron after a jump drive failure (Field Manual: Warden Clans)
CSR Mountbatten - adopted by Clan Snow Raven, originally the SLS Mountbatten (Field Manual: Warden Clans)
CWS Nicholas Kerensky - adopted by Clan Wolf (Field Manual: Crusader Clans)
CJF Falcon's Nest - adopted by Clan Jade Falcon (Field Manual: Crusader Clans)
Based on that list, it would seem most likely that the 2 Texas-class vessels that TRO:3057R reports as being destroyed in the Exodus Civil War are the SLS Perth and the SLS Bismark - the former is described as being partly non-functional, and it would seem reasonable that as a part of Nicholas Kerensky's rewriting of history he had the Bismark listed as destroyed in the civil war, rather than being stashed in the Norfolk boneyard and then stolen by the Wolverines - but I wanted to ask if that's actually correct?
I'm a little wary of making assumptions where the Bismark is concerned, because it might be that the Exodus had 8 Texas-class ships in the convoy, that the Clans fought another Texas-class ship during the Exodus Civil War that isn't named in Op KLONDIKE, and that the Bismark was simply erased completely from history. I don't know if there's a list of such minutae as the names of all seven ships in the class to survive the Hegemony Campaign and the Exodus, but the details in TRO:3057 and the various books that touch on Clan-space Texas ships are just complete enough to make me want to solve the academic puzzle they pose if it's possible.
