During the same incident in which Captain Picard encountered the refitted Enterprise-D, he also encountered a Klingon vessel similar to the current Negh'Var class. The history and capabilities of the class are largely uncertain. They are known to have possessed shield systems and disruptor armament 
, but it is reasonably safe to assume that torpedoes were also fitted to these ships and armour at least the equal of the standard Negh'Var is likely. Some form of transwarp drive is also likely to have been present, since the Federation of this timeline possessed this technology.  Externally similar to the standard Negh'Var, the Voodieh did have some detail differences on the hull which are 
probably related to more advanced sensors, weapons and drive systems. Two of these vessels attacked the USS Pasteur, inflicting fatal damage. The USS Enterprise-D arrived to assist, and although it was unable to save the medical vessel it did destroy one Klingon ship and force the other to retreat. The brevity of the battle indicates that the refitted Galaxy class outgunned the Voodieh by a comfortable margin.

||Stated in the DS9 TM. We're assuming that this ship is the same size as its DS9 counterpart.
The episode "All Good Things..." was actually the first appearence of what would later come to be known as the Negh'Var class. The ships seen here differed somewhat from the DS9 version, in that they had some extra doodads on the hull - most notably two fang-like features on the undersiade of the head. Relatively little is known about the ships, but while it's possible that they were some entirely different class than the DS9 Negh'Var, my best guess is that they are descendants of the DS9 ship slightly refitted.
We know little of their capabilities, but transwarp is almost a certainty. When the surviving Klingon ship retreats from the Enterprise, it covers half a light year in a matter of 30 seconds or so. This is over half a million times the speed of light, and clearly indicates some kind of advanced drive system.
