The “Jumbo”-Class DropShip represents not so much an individual design, than it does an entire class of DropShip designs. The race to space and colonization boom in the 22nd and 23rd centuries gave rise to the basic naval technologies and design philosophies still employed today, while the 24th century saw those concepts rapidly mature with the general technological boom. More and more ships were needed to transport more and more cargo to more and more worlds. In an era of relatively small DropShips with limited cargo capacities, such as the Manatee-Class, the Jumbo was the answer to out-of-control shipping costs.

Unsurprisingly, it was the Terran Hegemony that debuted the first Jumbo-Class DropShips – each of the massive spheroids capable of carrying more than ten-thousand metric tons of cargo – in the early decades of the 25th century. But as soon as these first “Jumbo” ships started plying the interstellar shipping lanes, DropShip manufacturers across the Inner Sphere began designing and building their own versions of the Jumbo.

In their day, the Jumbos were the pinnacle of civilian shipping, and in fact, moved more than their share of military cargoes during the final days of the Age of War, and the early days of the Reunification Wars. They all had massive cargo capacities, and were very hardy vessels built to survive rough handling as well as limited combat operations. The two small craft bays are very much a hold-over from its older design paradigm that saw a majority of the ship’s cargo transferred using shuttles, but did give Jumbo operators an improved flexibility in operations.

When they debuted, the Jumbos were revolutionary DropShips that changed the face of interstellar shipping. They ruled the space lanes for more than two centuries before advances in naval design and automation made newer designs with smaller crews and more reliable engines far more cost effective to operate. In the 28th century, the reliable Mule-Class DropShip took the place of the Jumbo in most shipping concerns, and ultimately replaced many as worn-out Jumbos were scrapped. Nonetheless Jumbos have continued to remain in service throughout the Succession Wars.

The Jumbo’s interior resembles that of other spheroid DropShips, such as the Union or the Seeker. Its fusion power plant and engine core are contained in a fat, cylindrical section that runs about two-thirds of the way from the bottom to the center of the ship.

In a ring at the outer edge of the Jumbo’s lower deck is an equipment section for the maintenance of the ship’s four sturdy, permanent landing legs. Also in this ring are the ship’s main heat sinks, fuel tankage and aft weapons bays.

Filling the space between the equipment rings and the engine core is the lower cargo bay, which holds 4400 tons of cargo, or approximately 45% of the Jumbo’s total capacity. Near the center of the bay are the central well of four (4) 200-ton capacity cargo elevators used to carry cargo between this deck and the two other cargo decks in the upper area, and on towards the docking collar at the front. Opposite the elevators, are the loading ramps used when the ship is grounded.

Two other cargo decks lie above the ship’s drives, the lowest holding 4400 tons of cargo, while the upper contains space for only 1330. The reasons for the smaller capacity of the upper level is its narrower circumference, but it also shares space with the two small craft bays and their maintenance and their own separate fuel tankage. This last deck also connects directly with the docking collar through its central elevator wells, and is often used as the loading/unloading area during docking operations.

Above the cargo decks are the three large command decks. The top-most deck contains the docking collar, the ship’s avionics and electronics, and forward weapon’s bays. On the deck below it are the vessel’s spacious bridge, a large personnel airlock for direct docking with other ships, water tankage, food storage, personal gear lockers, the medical bay, a large mess facility, a comfortable lounge, and the numerous single-occupancy staterooms for the ship’s crew.

The bottom-most deck of the command section are the waste-processing facilities, including a large hydroponics garden, the ship’s laundry, life support and emergency batteries. Also in this deck are several specialized areas. One is an observation room that overlooks the upper cargo deck and docking collar connection with numerous angled windows and a large communications suite capable of reaching anywhere within the local system (1000 AUs range), keeping contact with purchasing agents and trade factors. The crew and passengers often use this area as a separate lounge.

The second contains three large, wall-sized screens that display local system exchange rates, and pricing for local services and trade goods. The screens are tied to the ship’s communications suite to provide various system marketing agencies, and updates in as real-time as distance will allow. Many periphery or backwater planets do not have access to this sort of information in a central hub, and so the screens will display estimated market prices and exchange rates. In the room is a central communications console, and a table with chairs to allow the ship’s captain/owner to plan trade opportunities.

The final section of the lowest command deck is a passenger area with rooms for eight (8) second-class travelers, and a common room providing barrack-style space for ten (10) steerage-class passengers. All passengers share the same washroom facilities, and have access to the ship’s various command deck areas, such as the laundry and main lounge. Typically, Jumbo’s haul various factors from various shipping firms, who broker their company’s goods as the ship travels from port to port; few independent merchants can afford their own ship.
