And here it is, the 600 ton cargo barge as detachable cargo for surplus Copley’s following Jeff’s comments.

This is an example of a 600 ton cargo barge developed for use with Home Navy surplus Copley Class System Defence Boat Jump Shuttles. Standard operating procedure is for the barge to be loaded with cargo containers for a just in time arrival of the Copley Jump Shuttle. The surplus Copley arrives with a 600 ton barge, detaches, re-fuels, resupplies, changes crews when needed and then picks up the loaded barge for a jump to the next destination. This allows for the barges to be loaded and unloaded as needed, at leisure so to speak, while the Copley’s turn around is completely minimised allowing for the maximum amount of jumps per year.

The barge requires an engineer as crew and a small stateroom is provided, however the engineer usually stays in the spare stateroom on the Copley during jump. Extended life support is only provided in the stateroom and the engineering workspace. When attached the barge and the Copley are connected allowing the crews to move between both as needed.

The excess power provided from the minimum size fusion plant, allows for any refrigerated cargo containers to be powered from the barge directly, and allows for the full recharging of their batteries while in Jump.

Hi Jeff,

Now that’s a really interesting idea that just hadn’t crossed my mind. Thanks Jeff.

Basically just replace the SDB with 600 tons of detachable cargo, in whatever configuration you like. You could have a modular space frame, and just plug bits onto it as needed. Or you could have a 600 ton hull with minimal everything just full of cargo containers, or just as a bulk carrier full or ore.

Copley comes in with 600 tons of detachable cargo, drops it off, refuels/re-supplies/changes crew, picks up the 600 tons that’s waiting for it and jumps out. Which leaves the loading and unloading @ the destination and the Copley in space being efficient with as many jumps as it can make.

It would have to be between known destinations, but hay the efficiency of it would be the key.

Best regards,

Ewan

Pretty slick!

I can see a market for the older Copley's though.
Change the grapple around and you could carry a dozen cutters... or 6 cutters and a bunch of cargo pods.
Jump in, make deliveries to all the planets in the system, jump out.

Well I got to thinking about deployments and schedules and maintenance etc. So this is the evolution of the TL9 Jump Shuttle (next is the TL10 SDB and then SBDs as battle riders as per TNE but originating from the maintenance perspective (as per my thinking about deployments)). Anyway.

Comments welcome.

The Nicholson class System Defence Jump Shuttle is a county design using the latest in shipbuilding techniques as a replacement to the Copley class. Designed to move the Cane class SDB to where they need to be deployed the County Navy learnt lessons from the continued and non-stop movement of SDBs for maintenance and repair and these were incorporated into the Nicholson.
The main development was the ability for the Nicholson to re-fuel itself my means of the Pawel Class Modular cutter and a fuel module. It takes 10 fuel runs to replenish the Nicholson’s tanks. The other lessons were around the fact that the arrival of a Jump Shuttle usually heralded requests for assistance from the long duration SDB patrols including medial assistance, the need for replacement crew and the occasional re-supply of armament. With patrols of SBDs being usually two or four vessels the Jump Shuttle would only be replacing one of the SDBs, sometimes without a replacement crew accidents happen or crew health declines, so the Navy instigated a Medic in the crew of the Nicholson along with 5 frozen watch members to act as replacement crew as needed. Patients could then be treated in the sickbay as needed, and members of the SDB patrols can access the Nicholson’s Gym for the time the Jump shuttle is on station.
The Nicholson is luxurious compared to other county ships. Each crew members gets their own full size stateroom, although if there is a need to carry passengers double bucking is provided for the artificial gravity and inertial compensation mean that a normal 1G environment can be maintained for optimum crew health without degrading from a microgravity environment.
                When the Nicholson is on it’s on it achieves the stats listed above, and has fuel for 2x jump 1s, however it’s expected function is to move Cane’s where they need to be. When the Jump Shuttle is docked with a Cane the combined 1000 tons of vessel can achieve 0.4 G and Jump 1, and while the ships are not expected to fight while docked, it is possible to do so, and all crews drill to do so. While the ships are docked they are connected allowing the crews to mingle while in jump which can be a relief for a Cane crew that has been on a long deployment allowing them access to the 1G environment of the Nicholson.
