Though impractical to mount on BattleMechs or ProtoMechs, bulk cargo bays are a common sight on nearly any other type of long-haul mobile unit, including Combat Vehicles, Support Vehicles, DropShips and other capital spacecraft. Even some models of IndustrialMechs and the occasional aerospace and conventional fighter have been known to devote space and tonnage to internalized cargo bays.
Most cargo bays are generic—little more than an open space within the unit’s framework, with clamps and other anchor points for retention straps. Precious little else goes into these bays, as the aim is simply to maximize load space at any given time. Variations include fixed-cubicle style “container storage bays,” liquid stores, insulated stores, refrigerated stores and even bays developed primarily to haul livestock in something approaching safety (if not necessarily comfort). The weight and volume devoted to these bays varies with the needs and design of the hauling unit.
Vehicle engine and chassis designs today account for such bays as “fully-loaded” items, and thus do not gain appreciable speeds or better handling from running with empty cargo stores. The reasons for this engineering standard are beyond the scope of this discussion.
If a critical slot containing cargo is hit, all cargo in that location is destroyed.
May be mounted on any available unit type with adherence to the following construction rules:
Not allowed if Land-Air (Bimodal), or Land-Air (Standard) is selected for the unit’s Chassis
