A second-line Clan 'Mech feared by many Inner Sphere pilots, the Supernova seems to be an advanced version of the Black Hawk, though it was actually developed before that venerable OmniMech. Plans to replace the King Crab's loadout with clusters of Large Lasers grew from a shortage of autocannon ammunition. The first prototypes met with little success due to the King Crab's integral Ferro Fibrous armor, but gave rise to a lighter and leaner new design.
It possessed average mobility for an assault 'Mech of its size, with a top speed of 54/kph provided by a standard fusion engine. Mobility is further increased with Jump Jets, making it capable of 90 metre leaps. It is built on a Standard chassis, with 14.5 tons of Standard Armor providing protection. Just like the Black Hawk's Prime variant, it is made to survive long battles without depending on supply lines. [Source: sarna]
