The Vahklas class was a Vulcan design [1] common in the late 21st and early 22nd century. The ship shows tyical design features of Vulcan ships of this period; the nacelles show clear progression towards the ring structure [2] which would be a feature of the Surak, [3] Sh'Ran [4] and D'Kyr [5] classes, while the large central hull is an ancestor of the more streamlined axial hulls of the Surak [3] and Sh'Ran [4] classes.

By 2150 the Vahklas class was considered obsolete, though a handful remained in use by civilians. [1] By 2154 a group of these ships had been reactivated by the High Command for use in the planned war against the Andorians. [6]

The Vahklas was first seen in Enterprise "Fusion". We know relatively little about the ship except that it is pretty much obsolete by this episode - T'Pol declares that the ships have not been used in a long time, and considering Vulcan life spans that could mean centuries.

The most interesting feature is the partially ring-shaped nacelles. Since enterprise-era ships have full ring nacelles, it seems that this is a feature which has evolved over time - early Vulcan ships probably had nacelles on either side, and these gradually become more elongated and curved until they finally met above and below. It is always nice to see a logical progression in ship designs like this.

We don't have a class name for the Vahklas, so I have followed my policy of using the name of the first ship seen as the class name until we get something more official.
