How can I make a Jump-3 with "Jump-1 Drive"??

[dgmonteavaro]

How can I make a Jump-3 with "Jump-1 Drive"?? I mean, is there any posiblity that there's a kind of ship that transports other ships like a "big carrier". I don't mean a huge ship that a Fat Trader fits inside, not... I think in a long ship that can attach other ships much more little, and take them into a 3-Jump because has a big J-Drive to do that...

I say this thing because one ship can get bored of being in the same route all the time and needs to go to another group of systems.

Maybe the price should be 1 MCr/(Kton·parsec) of ship, thinking fast

I think in a long ship that can attach other ships much more little, and take them into a 3-Jump because has a big J-Drive to do that...

Of course this is possible, this kind of ship is usually called a "Jump Shutt-
le" or "Jump Tug".
All the ship needs are a jump drive and power plant powerful enough to
jump the additional volume and docking clamps as described in the High
Guard supplement.
In my opinion the price to transport another ship should be the same as
for the transport of the same volume of cargo, because in such a case
the transported ship indeed is a kind of cargo.

Yup, a carrier ship can be made. You need to figure the jump drive and fuel tonnage to be enough to support the mass of the carrier ship and whatever it is going to carry. High Guard has docking clamps that can be used for this purpose. And even mentions it:

The battle rider is a combat craft without a jump engine, typically about 30,000-tons but it can be much larger or smaller, the tender is a much larger but lightly armed ship with enough cargo capacity to hold one or more battle riders. The tender jumps into the disputed system and deploys its riders."

or if time is not a factor

Get a Navigator, who is licenced to plot deep space jumps and put enough demountable fuel tanks in your cargo hold to make 3 Jump-1 .....

Civilian jump ferrys can be modelled after military Battle Rider Tenders, or after modern wet naval carriers, or after tugs, or after river ferries. Some will be specialized, some general purpose. The term that arose late in the Rebellion era in Ley Sector is named for the region, and the Ley Liners kept commerce going even as the number of viable jump drives declined due to war.

 

[Rikki Tikki Traveller]

Personally, I would just convert some of the cargo hold to fuel tanks and make 3 Jump-1s. Takes longer (3 weeks vs 1 week), but it is perfectly doable.

 

[kristof65]

I'm with Rikki, but there are areas where civilian versions of battle riders could make some good economic sense, though.

If you have a region of space where a j-4 or up could cut weeks off of travel time, a specialty "ferry" to service independant traders could potentially be far more profitable for both the operator and the traders.

A 1000 ton dispersed structure ship with a capability of transporting 5-10 free traders (or equivelent) J-4 or more seems workable. Ship wouldn't be much more than a large J-drive, fuel, a small m-drive and crew quarters. Might be a good use for a surplus naval battle rider carrier.

Hmm - might even be a good way for a sector navy to utilize those carriers when not needed for other things.

 

[Rikki Tikki Traveller]

Depending on the star configuration, you might be able to justify something like that.

Say two fairly large clusters/mains with a J3 gap between them.

SOMEONE will set up a ferry for ships. As Kristof65 said, good use for those surplus battle tenders.

 

[kristof65]

battle tenders.

Aha! Couldn't for the life of me remember that term.

 

[GypsyComet]

Of course, Battle Tenders are often much MUCH bigger.

To keep High Liners profitable, I tend to go with a hybrid approach. Built with the ability to ship either standard containers (4 dtons each), pre-packed Cutter Cargo Modules (30 tons each) or both internally, the High Liner has a dedicated cargo capacity as a 3,000 dton ship, but also has external clamps to handle another 1,000 dtons of riders, and is route-specific in its installed jump drive.

 

[alex_greene]

I like the idea of Jump tugs. Mongoose High Guard introduced the idea of large (200kt) supersized cargo haulers owned by the Megacorps; it wouldn't be a stretch to put together the commercial version of a distributed-hull, high Jump BattleRider, designed to carry a whole lot of Type-As to a cluster otherwise not immediately accessible to the Free Traders. Each Free Trader would pay a chunk of cash to the Jump bus for the fare there, in the same way as an individual passenger books a trip on a free trader.

*reaches for his copy of High Guard*

 

[Gee4orce]

I've often thought that the Scouts could do with a J-4 frame that a type-S can slot into and give it that extra bit of range.

 

[alex_greene]

It's highly likely that they have something like that. Create a large distributed frame, a high Jump drive, fuel storage and latch on a small fleet of Type-S workshorses. The ScoutRider Jumps into the target system, unloads its fleet, and they take off in all directions to scout the surrounding worlds. A few weeks later, the survivors Jump back and it's off to the next strange new world.

And if there isn't anything like it listed in Book 3, the race will officially be on to design one.

 

[darktalon]

CT's Fighting Ships supplement had a vessel called a "Jump Ship", which was a Jump-6 equipped ship with equipment for carrying external cargo when jumping. This could conceivably include other ships, though the description indicated it was mainly used for cargo.

 

[dgmonteavaro]

In Supplement 2 i hadn't seen the Salvage hauler and Salvage Ship for three 2.000ton and one 300 ton, respec, for carrying ships.

The Makiidi class ferry ship:

http://www.stempest.demon.co.uk/traveller/SI-Makiidi.html

Extract from the blurb:

In the year 35 (Imperial Vilani date) the Shadow Emperor authorised new laws for the regulation of commerce within the Ziru Sirka. This marked the formal beginning of the makiidi or "ferry" system that would govern trade within Vilani space for the next 2,000 years.

The heart of this system was the vast dispersed-structure ferry ships built in the tens of thousands by the three Bureaux. Each of these was built around the Ziru Sirka's most precious secret: a Jump-Two drive. While Jump-One ships were plentiful in private ownership within the Imperium, the only way they could cross the rifts between clusters and mains was by hitching a ride in a state-owned Makiidi ship.

The design of the Makiidi did not vary much in the 2,000 years it was in production. When unrest within the Imperium began to be a problem, it was thought necessary to give the ships a light armament to ward off pirates and rebels, along with a security detachment of marines. However, since the ships operated between fixed bases which were normally heavily defended, there was no need for greater changes.

In operation, a Makiidi was able to carry 25 400-ton R-Class ships and 150 200-ton A-Class ships, plus 2,587 tons of cargo. The ship relied on obtaining refined fuel from starports: since they spent their careers shuttling from one side of a rift to the other that was rarely a problem. Each makiidi normally operated according to a fixed schedule, which became the foundation of patterns of trade in its sector.
