Fuel Storage Issue

[JRoss]

Apologies if I'm not the first to note this. So, we have to devote 10 x Jump rating hull points towards fuel storage. Here's what's weird to me. If a Jump 9 (!) drive requires 22% of your hull points, you can't ever fuel it because you need 90% of your space devoted to fuel, and that's 112%. Additionally, a Jump 8 engine takes up 20% of space, and requires 80% of the hull for fuel storage.

Could be done with drop tanks. There's also reduced fuel consumption for higher TL drives.

 

[JRoss]

True. Reduced fuel consumption can decrease by up to15%, which in the case of Jump 9, reduces it to 75%, so you end up with 2.5% left over for a bridge, power plant, life support, crew quarters and anything else.

Probably why I'm not even peeking above Jump 6. Granted, yeah, Jump 9 - even if attainable is a little heft

Collectors! All the fun of Jumping, none of the fuel issues. Not for time sensitive issues however. Slow and steady wins the race.

 

[JRoss]

But don't they send fuel to tanks?

Also, collectors are still faster than flying to the Gass giant and skimming.

I've not even begun to look at the >15TL stuff... there is naturally an end point of the current ship build paradigm with its percentages. I'd mentioned this previously when looking at TL curves and how sometimes it's not 'natural' in Traveller. Generally things don't just get uniformly larger, and the advantages attempt to address that to a point. But maybe at TL18 or something it's time to roll out warp drive

Jump 9 obviously needs to be able to work, but it _is_ in there out of a sense of completeness more than anything...

Oops, sorry I'm late to the game, but I assumed without checking that this was >>TL15.

I remade a test BB from another thread (210 kt, J3,9G,Prot15, 8*PA spinal,CGr142) with Collectors instead of jump fuel. The new ship with the same performance and offensive weaponry is 70 kt and GCr49.

So I get THREE times as many ships with a total of THREE times as much offensive weaponry for the same price. And this was a J3 design, J4 will be much bigger difference.

Please move this beyond TL15, or beyond TL17 (I will of course use Early Prototypes of Collectors if I can).

Probably best to start a dedicated thread on the High Technology chapter so these loose ends all get tidied up together AnotherDilbert.
