Are there any Vulcan Battlecruisers shown in canonical Star Trek?

The Vulcans have at least one canonically seen combat vessel: the D'kyr class "combat cruiser". It's both well-shielded and well-armed as well as being quite nippy.

ARCHER: Take a look at your long-range sensors. There's a Vulcan combat cruiser a few million kilometres from here. Unless you want to upset them, I suggest you turn around.

This class of vessel is referred to in the scripts as being a

powerful-looking Vulcan ship[s]

In the Extended Universe, we encounter an even more formidable Vulcan ship, the ShRaan-class, described as being even more powerful than their combat cruisers.

Dropping out of warp were two more DKyr-type combat cruisers, and one of the larger, better-armed ShRaan-class ships, which looked like a spear jammed through a hoop. The weaponry the newcomers carried between them would be more than enough to blow both Columbia and the remnants of the cargo fleet to little more than drifting trails of vapor in a few seconds, polarized hull plating notwithstanding.
