When Starfeld realized that the Z-10 Seeker was gong over big in the freighter market, it quickly designed a dedicated freighter using using the Seeker as a model but eliminating most of the Seeker's flaws. The resulting ship was the ZH-25 Questor.
The ZH-25 uses the Z-10 fuselage with two additional hull sections, for extra room and a one hundred percent increase in cargo pod size. The additions increased the ship's mass by almost 300 percent, requiring the Novaldex JV-71 ion engines to be upgraded to more powerful JV-74s. In spite of the improvement, the ZH-25 is still slower than the Z-10, and somewhat less maneuverable.
Arms and armor were a real shortcoming in the Z-10 parent model. The BlasTech Prim-3 lasers were completely replaced with Taim and Bak pulse lasers, a favorite in Corellian-designed ships, with independent targeting/ firing computers, eliminating the sensor blackout problems that plagued the Z-10. Perhaps most significant is the inclusion of a Sirplex P-12 shield generator, greatly increasing the ship's durability. |
