Quarren patrol ship

From Memory Alpha, the free Star Trek reference

A Quarren patrol ship was a type of 24th century patrol ship used by the Quarren for patrolling Quarra.

When Harry Kim and the Doctor were in command of USS Voyager in 2377, they were fired upon by Quarren patrol ships. They managed to disable two pursuing ships by using a photonic shock wave and they were forced to retreat. (VOY: "Workforce, Part II")
