Devore warship
From Memory Alpha, the free Star Trek reference
The Devore warship was a type of starship operated by the Devore Imperium in the the 24th century. Two of these vessels substantially outgun a Federation Intrepid-class starship. They are equipped with refractive shielding, which renders them difficult to detect on sensors.
The USS Voyager was stopped for inspection by several pairs of Devore warships while passing through the Devore Imperium in 2375. (VOY: "Counterpoint")
