The USS Trial was a Federation starship of the Miranda class, which was in service in the 24th century.
In 2372 the Trial visited Deep Space 9 for a brief stay. (DS9 "The Way of the Warrior")
It is implied that the Miranda class that was shown along with the USS Venture is the Trial and that it is the Ertl kit instead of the Reliant model from Star Trek: II The Wrath of Khan.
