USS Myrmidon (NCC-1500)

The 'USS Myrmidon (') was a Federation starship, a frigate in Starfleet service in the mid-23rd century. Captain Daugherty was the ship's commanding officer. 

Service history and disposition
In the year 2270, the crew of the Myrmidon were among the victims of blastoneuron neural parasite infection in the Deneva system, which also affected nearby Deep Space Station K-13. Under alien influence, Captain Daugherty led an attack on the USS Pioneer (NCC-1500), which arrived to render aid. A Starfleet away team eradicated the infection from the space station, and the Myrmidon joined in battle against a Na'kuhl destroyer from the 29th century.
