The Tal'Kir was a Vulcan D'Kyr-type combat cruiser that was in service with the Vulcan High Command in the mid-22nd century.
In 2152, the Tal'Kir was assigned to rendezvous with Starfleet's Enterprise NX-01 to transfer a time travel pod from the 31st century back to Earth. While waiting at the rendezvous coordinates, the vessel was attacked by four Tholian starships, which disabled the Tal'Kir's engines and weapons and badly breached the hull on its port side, though life support remained stable.
After the Tholians withdrew, the captain of the Tal'Kir pointed out to Captain Archer that "a ship can be replaced." Archer noted he wanted to send his appreciation for helping them, and Enterprise continued on its mission. A Vulcan ship was later sent to tow the Tal'Kir back to Vulcan
The ship itself is a nice model, the same as the previous D'Kyr, though the science module is the other way up on this one. I think it is a great looking ship, and a good addition to a very limited faction.
