The USS Bretha (NCC-3325) was a Hellespont-class escort that saw service with the Federation Starfleet during the 23rd century.
In 2277, the Bretha accidentally crossed into Gorn space and was engaged by two Gorn vessels, sparking a major diplomatic incident. (Ship Recognition Manual, Volume 4: Starships of the Original Series Era)
