In one timeline the Zahl had destroyed the Krenim Empire and taken over their space. In this Zahl-dominant timeline USS Voyager encountered two of these vessels whilst passing through the area. Both ships vanished when an incursion by the Krenim Timeship altered the timeline to a more Krenim dominant one.
Very little is known about the ships. They can be assumed to have significant warp capability and weaponry, but no details are available. 
|Year of Hell, Part 1
|Based on a visual comparison with Voyager in 'Year of Hell, Part 1', and on a window height of 3 metres.
Of all the Year of Hell ships, these are the ones we know least about. We see a couple of Zahl ships which meet Voyager after its first encounter with the Krenim, and their size is based on visual comparison with the Starfleet ship in this scene.
The Zahl go the way of the dodo when the Krenim blast their home world with the timeship, and that's the last we see of these ships. We never see them at warp speed, we never see them fire a weapon, never get a look at their interior. As is usual with alien ships, I've not made up any specs since the real DITL wouldn't be expected to know about the ships of a species located tens of thousands of light years away.
