Tristar-class cruisers often served as Flagships of the Southern Cross, and led squadrons of vessels in the REF.

The Tristar was a fold-capable vessel, and it was this class of vessel that first employed a hazardous variation of the usual fold to create an "orbital warp blast", which was used to destroy an attacking force of Robotech Master battleships and bioroids by dragging them into an artificial singularity. It also had powerful conventional engines, arranged into a cruciform pattern on the rear hull. Indeed, because these and the other second-generation naval vessels were all of similar shapes and painted in dark colors to minimize visibility in space, it was often only the engine configuration that allowed one to distinguish one vessel from another.

The most famous ship of this class was the vessel that bore the class name, which was the flagship of General Rolf Emerson throughout the latter half of the Second Robotech War. This vessel led missions to refurbish Luna and ALuCE bases on the moon, before returning to Earth to lead the penultimate and final attacks on the Masters' fleet. She was finally lost in a ram against one of the Motherships. Some several dozen vessels of this class were built, and most were lost in the Second Robotech War.


The Tristar is the most heavily armed vessel of Earth's fleet in the Masters series. These vessels also have the largest bridge by area and crew of all Earth's Robotech forces.

In the Masters series one Tristar is destroyed and there is another three seen throughout the series.
