Just read through this thread.

As far as I recall (and you would have to trawl the archives) the “standard” jump drives in book 2 are the most efficient drives you can get in CT.

Which suggests, and what I believe the consensus of the list was, that they are all built at the best tech level they can be (TL15), and then shipped to various shipyards as “standard” drives you can just buy “off the shelf”.

This then provides justification against different drive letters providing different jump distances in different hull sized (they are all TL15) so they can provide higher jump distances in smaller hulls, or smaller distance in bigger hulls (as long as you have the computer to back them up).

But what they are not is a TL12 drive that can provide jump 4, because Jump 4 is TL13.

The TL to jump range is in CT. The TL charts in the Traveller book have them defined, and they may well be in starter Traveller or elsewhere as well.

Best regards,

Ewan

Hello Greg Nokes,

I can share the spreadsheet with the caveat that it is a slapped together construct that appears, aside from cost and crew, to work good enough for me, I think it works anyway.

Send me an e-mail and I'll send you a copy of the spreadsheet which is an Microsoft Office 2010 Excel Spreadsheet.

Are you sharing these creation system sheets that you are using? I’d love to have access to some sheets for older systems.

Hello Phil,

I'm trying to work on the calculations but the scratch spreadsheet I hastily put together is slowing me way down. I hope to have something in the next couple of days.

Before I get to deep I wan to make a quick check to ensure I'm calculating the right instance of J-max.

CT LBB 2 1977, 1981 and CT LBB 3 1977, 1981

TL 9 100 ton hull standard: J2 constrained by 15 ton drive space requirement and custom J3 by reducing Power Plant fuel tankage to 2 or 3 weeks of operation.

Is this want is being asked for?
