Drive Table

[ArcaneFlash]

I'm making a hybrid between MgT and T5 and is going surprisingly well. However, The T5 Drive/Power table is enough to make you wonder. A Z maneuver drive for example only powers a z size hull to a rating of 4 but an A Hull can go as fast as 9. That A Hull is running rings around the bigger hull.

In MgT the speeds are closer together. I'll still use the T5 table but it seems for the most part ships are really fast or really slow.

Does anyone really like the table or have they changed it? (p340)

The Table is fine as far as i can see, you can make vessels go as fast or as slow as you want, but you have to consider space and cost, bigger (more Powerful) drives take more room and cost more but make your vessel go faster, smaller ones are cheaper and take up less room but slow you down. Its all about mission statement and design parameters.

Further, in T5 you can install multiples of each drive with the proper linkage.

That should not be a big surprise, since many peripheral bits of Mongoose Traveller come from Traveller5, and Marc (and Don and I) had editorial input into MgT.

Have you seen my armor and weapon damage conversion chart, my simplistic skill level conversion chart, my starship hull mapping conversion, etc?

Mapping of Armor Conversion (T5 - MgT)

That should not be a big surprise, since many peripheral bits of Mongoose Traveller come from Traveller5, and Marc (and Don and I) had editorial input into MgT.

Have you seen my armor and weapon damage conversion chart, my simplistic skill level conversion chart, my starship hull mapping conversion, etc?

I noticed that the mapping of the armor conversion on armor and weapon damage conversion chart & starship hull mapping conversion seem to be different. Am I misreading the two charts?

EDIT: Would your tables also serve as a good conversion between T5 & CT Armor Factor, since CT & MgT armor values seem to be on roughly the same scale?

Thanks,
I just remembered the multi-engine rule but I wasn't sure how to use it. (or where it was)

The interesting thing for me was For a 2k hull:
Mgt: J Drive Z (125t, 240MCr, Rating 4)
T5: JDrive Z (125t, 125MCr, Rating 2)

While the T5 drive is cheaper, how do I add a 2nd ZDrive? Then does that make it a Rating of 4 and how does that affect the P-Plant?

If you use Multi-Engines and the formulas, How effective can you make larger than Hulls of 2400 Dt?

See: T5 P.338 Table 10 & T5 P.340 Table 12.

You link them together with a "drive nexus" (which requires no tonnage). You can link up to 9 drives (of any given type) together, and you may link up to 9 such "9-linkages" together as well.

Two Z-Drives linked together is a Z2 Drive (which is on the chart). Note that the EPs for a Z2-Drive (4800 EPs) are just the sum of two Z-Drives (2400 EPs each). If I wanted to link 3 A-Drives together, it would be an A3-Drive (and draw or produce EPs equal to 3 A-Drives [300 EPs], and have the dtons of 3 A-Drives). It would have the performance equivalent of a C-Drive (which also draws/produces 300 EPs).

I could link up to 9 Z9-Drives together (a total of 81 Z-Drives), which would be noted as a "9Z9-Drive", would mass the equivalent of 81 Z-Drives, and would draw (or produce) 2400 x 81 = 194400 EPs.

You use the EPs produced/used by the drives to compare the drive performances. Two drives that both produce or draw 600 EPs (for example) have the same performance level.

If you use Multi-Engines and the formulas, How effective can you make larger than Hulls of 2400 Dt?

The ACS Ship Design system in the T5 Core Rules is not intended for ships larger than 2400dton. A forthcoming supplement (BCS Ships) will be for designing vessels 2500dton and larger.

whulorigan,

Thanks, that is awesome.

I assume then, For a Type Z Hull, A Z Drive does J-2, Z2 drive does J-4, then Z3 drive will be J-6, etc, but now it is getting both massive and expensive.

So, I assume if you use a Z3 J Drive then you need a Z3 P-Plant. Wow gets expensive.

Correct. And don't forget the fuel tankage to support those drives. (Ultimately, for certain levels of performance, you ideally need an Antimatter Power Plant if you are of sufficient TL to build them).

Also remember, though, that in T5 there are "Stage Effects", meaning that equipment manufactured at a TL higher than its baseline TL will have efficiency and size benefits. So if you are building a Jump-2 Drive, for example (which is base TL-11), if you build the drive at a TL-15 shipyard you are building an "Ultimate Jump-2 Drive" (4 TLs above baseline), and that gives you efficiency savings in terms of tonnage and fuel consumption.

See the Drive Efficiency Tables and Formulas on T5 p. 322, 338 (right column), and 362.
