The Zybatzu Tuning House

The Zybatsu are a galactically famous group of wizard tuners and engineers who have come to develop an exclusive contract with CEC. In essence Zybatsu take in a certain number of semi-complete CEC hulls each year, and then tweak the engines, improve the CRMS systems, upgrade the computer systems and generally overhaul the basic design to create a much more powerful vessel.
Z finished CEC ships are faster, more nimble, have better range, are generally better armed and tend to have sexier interiors. Typically the exterior is more or less identical to a stock CEC model except for the small golden 'Z' fastened to the front of the canopy.
