Extended Fuel Tank

The concept of the extended fuel tank is hardly new, but entered widespread use in the days of pre-myomer, ICE-driven IndustrialMechs, when those walking monstrosities chugged away entire liters of fossil fuels every minute. Today’s far more efficient engines have made great strides—no pun intended—since those days, but even so, fuel remains the limiting factor for all non-fusion/non-fission units.
Using the same basic technology as the external hardpoints described later for aircraft units—but mounted internally to protect the reserves of volatile chemicals or fuels—extended fuel tanks (available for ICEs and fuel cell engines) vastly improve a unit’s basic operating range, depending on how many are installed. In the case of most internal combustion engines, a single tank weighing one tenth as much as the engine itself can add about 600 kilometers’ worth of mobility, doubling its effective range. Matching such capabilities point by point, fuel cell-powered units gain about 450 extra kilometers for the equivalent ratio of added tanks, which also effectively doubles their stamina in the field.
Each filled or partially filled extended fuel tank is treated as an ammo bin in combat, and will explode for 40 points per ton of tank if it suffers a critical hit (regardless of whether or not the unit is shut down or the pilot is conscious).
May be mounted on any available unit type with adherence to the following construction rules:
Not allowed if Fission, Fusion, Primitive Fission, or Primitive Fusion is selected for the unit’s Engine Type May only be mounted in the Torsos
