The Wildcat represents a renewed Clan Star Adder presence in 'Mech design and production. Its inspired, razor-thin silhouette belies an Endo Steel frame and thirteen-and-a-half tons of Ferro-Fibrous armor, components normally seen on much bulkier 'Mechs. Housed within the narrow framework is a modified 300-grade engine, allowing the Wildcat to move at a respectable 65 km/h while still maintaining just enough space to include its weapons loadout. To handle the excess heat generated by its array of energy weapons, Star Adder engineers also squeezed 11 double heat sinks into an already crowded space.
The Wildcat has the necessary components to support a Guardian ECM Suite, jump jets, a Laser Anti-Missile System, and an advanced Gyro system, but does not have the space for them in its primary configuration. [Source: sarna]
