It does seem that the only episodes to discuss warbird performance are "Tin Man" (which establishes lower sustainable warp speed than for Galaxy
, but only if the Romulan engineer is too timid to redline the engines) and "Yesterday's Enterprise
" (which establishes that four of the old warbirds are no match for the weapons of an alternate-timeline Galaxy
and that any one of them is less maneuverable, supposedly at impulse, than the E-C).
We never learn much about the later (D'deridex
or "Type B") warbirds or their differences versus older models. "Timescape" tells us that their use of quantum singularity powerplants came as news to Starfleet in the aftermath of "Face of the Enemy", but since Romulans are so secretive, QS engines may have been in use for several centuries already... It's a bit surprising that the alternate Tasha knows enough about Romulans to establish the difference in maneuverability, but perhaps Romulans weren't quite as secretive in that alternate timeline?
