A Son'a battle cruiser in the Briar Patch.
Son'a battle cruisers were large warships utilized by the Son'a during the late-24th century. These vessels were 837m in length, and were known to be equipped with isolytic subspace weapons, as well as conventional photon torpedoes.
In 2375, two of these vessels escorted the Son'a collector through the Briar Patch to the Ba'ku planet. Their purpose in the Briar Patch was to protect the Son'a's interests in completing their mission.
They were later sent to prevent the USS Enterprise-E from leaving the Briar Patch, as it attempted to clear the volatile region of space in order to contact the Federation Council. The cruisers, which were outfitted with the capability of traverse the Briar Patch much faster than the Enterprise, intercepted the Enterprise nearly thirty minutes from the entry point into the Patch.
The two cruisers attacked the Enterprise causing moderate damage to the vessel, before firing an isolytic burst in its' proximity, forcing the Enterprise to eject its' warp core.
Then Riker, who was commanding the Enterprise, initiated a unique battle tactic that neutralized the Son'a threat. In the end, one of the battle cruisers was destroyed, while the other was on fire requesting assistance. (Star Trek: Insurrection)
- The Son'a battle cruiser was designed by John Eaves; the computer generated model was built by Blue Sky/VIFX. According to Eaves, the Son'a battle cruiser was created to resemble the appearance of a boomerang.
