The Shi'Kahr-class (also spelled ShiKahr-class) was a type of frigate in service to the Federation Starfleet in the 24th century. (Last Unicorn RPG module: The Price of Freedom; ST video game: Star Trek Online)
The Shi'Kahr vessels were constructed as a modification of the design of the venerable Miranda-class. By the 25th century, Shi'Kahr-class vessels filled a role as a Starfleet light cruiser.
Shi'Kahr-class ships were also occasionally seen under the command of the Imperial Starfleet, who considered them frigates. (STO video game: Star Trek Online)
The class was presumably named for the city of Shi'Kahr on Vulcan.
