The IRW Raptor One was a Romulan starship in service in the mid 23rd century of the Kelvin timeline. In the 2260s, the Raptor One was commanded by Commander L'Nar and served as a command ship during their alliance with Section 31.
In 2261, the Raptor One led the attack and massacre of the Klingon colony of Khitomer. Using advanced and very powerful weaponry provided by Section 31, Raptor One and the other ships were able to utterly destroy the colony leaving no one alive. (TOS - The Khitomer Conflict comic: "Part 1")
