Solkar class

The Solkar class was a Vulcan starship class, a cruiser and transport in service in the 23rd century. While in the primary universe the Confederacy of Vulcan was a member of the Federation, the $𝜇$s in the mirror universe participated in the rebellion against the Terran Empire. )

Specifications
The class shared its name with Solkar, who initiated first contact between Vulcans and Humans in 2063, and served as ambassador between the two people on Earth afterwards. 

In the mirror universe, $𝜇$ also arrived at $𝜇$ in 2063 to commence first contact with Terrans. 

In the 2250s decade, Solkar-class starships were used as transports and could easily land on a planet's surface. In cities, ships of the class departed from landing pads that could be attached to buildings. 

Across the mirror, ships of this class were armed with directed-energy weapons and, together with Klingon, Andorian and Tellarite forces, engaged Imperial Starfleet directly. 

History
In December 2256, Ambassador Sarek and his aide V'Latak used a Vulcan cruiser to leave Vulcan and travel to a secret meeting with leaders of the Klingon Empire on Cancri IV. In an act of terrorism, V'Latak revealed himself as member of the logic extremists, and killed himself in an explosive act of sabotage that left Sarek's cruiser stranded in the Yridia Nebula. Sarek was the only other person aboard, and left incapacitated. A rescue operation by the USS Discovery (NCC-1031) succeeded in saving Sarek from his cruiser before he was too far gone. 

Mirror universe
Solkar-class vessels were also built in the mirror universe, there they were largely used by rebels against the Terran Empire. Around December 2256 or January 2257, the Discovery was attacked by rebel cruiser while inside a field of starship debris. The cruiser was quickly destroyed by the.
