Two of the fastest medium mechs in existence, the Wraith and the Lightray were staple Word of Blake designs. Incredibly quick and maneuverable, they could act as heavy harassing units and point scouts for cutting apart enemy formations.
Nevertheless, Word of Blake engineers, ever trying to squeeze out more performance from their mechs, managed to combine the best features of both mechs into one stunning package: the STB-1U Starburst.

Just as fast as the Lightray, and jumping just as far as the Wraith, the Starburst shaves off five tons for more armor and accurate firepower.
Instead of arming the Starburst with a Wraith like loadout of pulse lasers, the engineers went with tried and tested technologies.
Armed with a Cyclops extended range large laser, and three standard medium lasers, the Starburst does not have a lot of firepower. However, it makes up for that by linking the lasers with an advanced targeting computer. This allows the Starburst to pick apart opponents with just a few laser shots.
The final piece of equipment is an improved C3 module. Since the Starburst is an infighter design, placing the C3i system on the mech makes it an excellent spotter for its combat mates.
With larger mechs like the Vanquisher punching holes in the armor of its opponents, the Starburst can target these locations to put down enemy mechs fast and effectively.

With the liberation of Terra, Starbursts, like many other former Word of Blake mechs, were earmarked for the various regiments of the Star League and Comstar. The impressive manufacturing might of Terra has been a boon to Comstar and the Star League, enabling the Star League to quickly assemble two new regiments from the volunteers from fighting the jihad.
Recently, almost a full Level 3 of Comstar Starbursts were deployed to the Free Rasalhague Republic, in order to hold against any Wolf or Ghost Bear aggression.
