Two of Tret's containment vessels and Enterprise in orbit of the Loque'eque homeworld.
Tret's containment vessel was a class of starship utilized by Tret's species to prevent any individual infected from the Loque'eque mutagenic virus from leaving the Loque'eque homeworld and infecting neighboring star systems. This class of vessel was armed with dual forward particle cannons, and were capable of exceeding warp 4. During the 2150s, a vessel of this class was commanded by Tret.
In 2153, Tret's containment vessel, and one of her sister ships, intercepted Enterprise in orbit of the Loque'eque homewhere, where they discovered a Loque'eque aboard the Human vessel. They declared that Enterprise was under quarantine, and that it they should prepare to be boarded. The commander of Enterprise at the time, Trip Tucker refused to be boarded, but offered to Tret that he may come aboard to discuss the situation. After departing Enterprise, Tret returned to his vessel, which remained in orbit alongside her sister ship and the Earth ship.
After Enterprise attempted to flee the two containment vessels, they both took chase, and quickly caught Enterprise, after nearly disabling her aft hull plating. Threatening to destroy Enterprise, the two ships stood down after they were offered an anti-toxin capable of reversing the mutagen. (ENT: "Extinction")
