The Brown class Jump Ship is a transport starship.

• It is a civilian ship and a Jump Ship.
• Some call them Jump Trains.

Description (Specifications)

The Brown class Jump Ship is designed to provide maximum flexibility in interstellar transportation. As built, it is capable of Jump-6 and 1-G. Special field cables attached to the rear of the ship extend the ship's jump field to include this additional cargo. Alterations in displacement will affect the size of the jump itself, but the amount of cargo carried can be varied to fit the needs.

Capabilities: For each 1,000 tons of cargo carried in the mesh cables behind the ship, jump is decreased by one. Thus, if the 5,000-ton ship carries 1,000 tons behind it, it can only perform Jump-5. If it carries 5,000 tons behind it, it can only perform Jump-1. In all cases, the internal fuel tankage of the ship (3,300 tons) is sufficient to support the jump.

Jump Pods: The jump ship can transport valuable raw ores, planetoid chunks, and other materials directly in its jump mesh. Only durable goods can be carried in this manner because they are exposed directly to the vacuum of space. To allow the transport of other materials, jump pods have been constructed on a variety of designs. Typically, each displaces 1,000 tons and can function independently of the jump ship.

Some basic designs for jump pods include the following:

• Cargo Pod: A bulk cargo carrier displacing 1,000 tons and carrying approximately 950.0 tons of cargo. Several varieties are available, including special liquid tankers, bulk food, or grain carriers, and compartmented transport containers. MCr100.
• Passenger Pod: A large pressurized hull with 225 staterooms, plus recreational facilities, safety compartmentalization, and fittings for comfort. MCr212.5.
• Low Pod: Similar to a passenger pod, the low pod is fitted with 1,900 low berths for carrying people or animals long distances. MCr195.
• Other Pods: Additional types of pods are possible, and have probably been produced somewhere in the Third Imperium.

Basic Ship Characteristics

Following the Imperial Navy and IISS Universal Ship Profile and data, additional information is presented in the format shown here. The small craft factor indicates the number of squadrons (...of ten subcraft) carried on the ship. Tonnage on the universal ship profile is shown in kilotons (...thousands of tons) where necessary.

Basic Ship Characteristics
No.	Category	Remarks
1.	Tonnage / Hull	The Brown class is constructed using a 5000 Ton hull built in a generally wedge-shaped configuration. The hull qualifies as partially streamlined, giving a relatively limited atmospheric performance that is reliant on its onboard gravitic systems. Individual sections of the ship are divided by bulkhead walls. There are multiple airlocks located around the vessel. The internal cargo hold is accessed by large doors and has a loading ramp. The vessel has a sturdy retractable undercarriage, allowing surface landings.
2.	Crew	Total Crew Complement: x38 x15 Command, x8 Engineering, and x15 Service Crew. Accommodations There are x20 Staterooms. x20 Staterooms are given over to crew quarters. The captain and senior staff receive individual cabins: other quarters are double occupancy. Accessible areas of the hull are fitted with grav plates and inertial compensators and have full life support and environmental systems. There are internal monitoring and security systems throughout the vessel. Sections of the ship can be isolated in the event of an emergency. There are multiple Emergency Lockers.
3.	Performance / Engineering	The vessel mounts a Jump-6 drive, a Maneuver-1 drive, and a Power Plant-6, giving a maximum performance of Jump-6 and 1G acceleration and producing 300 Energy Points. The ship has an agility rating of 1. The internal fuel tankage is sufficient for one Jump-6 and gives the power plant 4 weeks duration. The engineering section has a main control room. Ladders, gantries and platforms give access to the machinery. The jump drive utilizes a hull grid. The jump drive is fitted with a jump governor.
4.	Main Section / Electronics	Adjacent to the bridge is a Model/6 Computer: the ship is not fitted with a backup computer. There are multiple workstations and control points throughout the vessel. The vessel is fitted with communications equipment, an advanced sensor array, and has an Avionics suite. It has a transponder unit that can be deactivated on command.
5.	Hardpoints	x50 hardpoints.
6.	Armament / Weaponry	The vessel is unarmed.
7.	Defenses	The hull is unarmored. The vessel is not fitted with screens or other passive defensive systems.
8.	Craft / Drones	The vessel carries no subcraft.
9.	Fuel Treatment	The vessel has internal fuel tankage of 3,300 Tons. The hull is fitted with fuel scoops. The vessel is not equipped with fuel purification equipment.
10.	Cost	The basic cost of the vessel is MCr3,337.400 Architects Fee: MCr33.740. If multiple examples of the design are ordered all of the ships in the production run qualify for a 20% discount, which reduces the price per unit to MCr2,669.920.
11.	Construction Time	144 weeks (36 months) as standard. Build times can be reduced by mass production and the efficiencies such processes generate, by increased financing, and by allotting additional yard resources and facilities to the construction contract.
12.	Comments	Standard cargo capacity amounts to 140 dTons. The hold has independent life support and environmental systems. It can be sealed and isolated.

History & Background (Dossier)

Some have noted that a jump pod happens to be the same cargo tonnage of the much older Ghost Galleon class Cargo Ship design, which design sometimes carries pods in exactly the same way. While it is easy to imagine that the Brown class evolved from the Ghost Galleon, just up-sized to carry 6 pods and with better performance, there is no evidence to conclusively prove that this is what happened.

Class Naming Practice/s & Peculiarities

Jump Ships tend to be named in a number of fashions:

1. After famous gentlesophonts of distinction.
2. After the minerals, gems, and precious substances that they are often used to mine by belters.

In the case of the Brown class Jump Ship, it was naval by famous naval engineer T.J. Brown, a distinguished gentlesophont who designed dozens of popularly used starships, warships, and smallcraft. Modular technology has grown quite popular within Imperial Space and within the larger area of Charted Space, and his actions as a naval engineer reflect well upon him and the Imperial Navy, as well as the many megacorporations and corporations he later worked for.
