Enterprise engages in combat with the Kovaalans
The Kovaalans were a species native to the Delphic Expanse in the Milky Way Galaxy.
The Kovaalans were an aggressive and territorial, technologically advanced species who controlled a nebula in the Delphic Expanse during the 22nd century in which one terminus of a subspace corridor was located.
In 2154, while attempting to utilize the corridor to reach a rendezvous with the Xindi-Primate Degra, the crew of Enterprise NX-01 were forced to combat a number of Kovaalan starships. With the help of their counterparts from a temporally-displaced version of Enterprise from an alternate timeline, the crew was able to successfully negotiate their way past the Kovaalans, and safely pass through the corridor.

According to the Star Trek Encyclopedia, 4th ed., vol. 1, p. 441, the Kovaalans are the unnamed species from ENT: "Silent Enemy". The same model was seen to represent both species' ships.
