Beltstrike introduces a new CT ship, the Mining Platform.

Code: 
                 Tons  Cost
Hull             5000   500
W Maneuver        -41    84

50 sing turr             10
50 pulse las             25
175 statrms      -700    87.5

2x pinnace        -80    40

mass driver       -25   ???
process bay      -400
seeker bay      -1000

I have 680 tons still open by my count, and the cost is MCr1044. What's the missing space, and how much should that mass driver and/or processing bay cost?

Lessee... Model 5 costs MCr45, not 18


1330.7 * 100/101 (removing the architecht fees) = 1317.5
1317.5-1032.5 = 285

MCr285 to spend. If we call that a 25T launch capacity mass driver, and say it's a form of launch tube... that's 625T right there, so that's 600 of your missing 650, at MCr0.002 per T, for MCr1.25. We need more power, but not more space, so call it 4x cost, and make it MCr5. (Which, BTW, is the same COST and 12.5x the volume, of a 50T Repulsor bay. Which said device I can't find the operational effects of...)

MCr280 left... So the processing bay gets MCr0.7/Ton... OR... it's a 400 Ton Capacity, and takes 420 total tonnage - 400 tons of bay at MCr5 per ton, and 5%=20T @ MCr4/ton for control systems.....

1. I always build it with a Jump drive (or at least the engine room space for one), so it could transport itself to lower-TL systems that might not yet have the infrastructure to construct it. Then the J-drive can be removed and shipped elsewhere for installation in another platform, recovering the cost (if not the space).

2. I figured much of the unused extra tonnage was ore packing facilities and supplies storage, plus crew recreation and vehicle maintenance space. It is a pity Trav does not have good repair bay rules; a repair and maintenance bay is called for here.

3. The mass driver could be specced-out as alternatively a Striker-style gun, or an HG2-style launch tube. I lean towards the latter as it suggests lower velocity and payloads, making the packages too small to be useful as weapons against planets with Atmo-3+. Figure Repulsor-based technology, and therefore throwing approximately 1 dton @ 6Gs initial impulse; hardly a planet-killer or a budget-buster.

It's been a long time since I did that. I'll see if I can find any notes. If I can't, I'll re-do the reverse-engineering "out loud" to see if it helps.

Unless it's deeper in my stack of notes (entirely possible since there's probably another quarter meter to go through :o), I didn't find what I'm looking for. So I'll re-do it here.

You list the Mod/5 computer cost as 2 tons and MCr18, where I have 5 tons and MCr45. You list 50 mining lasers as MCr15, where I have 50 pulse lasers at MCr25. You have 10 buggies as 40 tons and MCr6, where I have 40 tons and MCr7.5.

Do we want to haggle over these numbers, or are we going with mine? :D

Once we have these straight, we can get to the pieces we really have questions about.

I've gone ahead with reworking the ship - and I've been even pickier than previously. I'll post the details later. I may have found our "eater of space", though not the cost sink yet.

You are right on the computer being 5/45. I thought I'd fixed that.

As to the lasers, I used the mining laser instead of the pulse laser (arrgh). And I know I saw a price for a prospecting buggy elsewhere, but since Beltstrike ACTUALLY defines them, we should use your numbers for all three.

Besides, none of that is what we're really after. Now, the good stuff.

OK, I've got BeltStrike in front of me now.
There's a "Laser Drill" listed (p9), but that's Cr7500 and 10kg. That's man-portable, not a starship weapon.

The Prospector's Buggy (also p9) is 4 tons and MCr0.750.
 
OK, the ship as we know it so far - a recap if you will. :devil:

                      40     7.5 10x Prospecting Buggy
                    1000     -   10x Seeker (optional purchase)
Other                 25     ?   1x Mass Driver
                     400     ?   1x Processing Bay
                    1690     -   Fuel for 1 yr + vehicles
Totals              4350  1044
Defined Totals      5000  1317.525
Difference           650   272.275

Crew: 1x Pilot; 1x Navigator; 3x Engineer; 0x Steward; 2x Medic; 50x Gunner.
Total Crew: 57.

If only the required crew is aboard, the second Medic position can be dispensed with. You could say the gunners can be dispensed with as well (at least just moving the ship from point A to point B), but that would leave only 6 people aboard instead of the minimum of 50 that a 5000 ton vessel is required to have.

I've left out jump drive, jump fuel, low berths, and streamlining from the listing since they'd just be blank lines (or dashes as I'd note them).

Does anyone wish to dispute (poke holes in, quibble with, view with alarm, or any other type of conversation) my numbers to this point? :D I'm using the rule sets and numbers from "The Traveller Book" and "BeltStrike". I've explicitly left the prices for the mass driver and processing bay unspecified since that's the point of the exercise. :)

Discussion Point #1

In B2, there's no carriage cost for small or big craft in either tonnage or cost. We could apply those concepts from B5 to use up some of the left over tonnage and cost as follows.

Small craft carriage:
B2: 235 tons, MCr0
B5: 305.5 tons, MCr0.611

Big craft carriage:
B2: 1000 tons, MCr0
B5: 1100 tons, MCr2.2

Total B5 carriage costs (beyond B2 levels):
170.5 tons, MCr2.811

If we applied this B5 carriage cost, we would still have a lot of tonnage and cost left over.

Difference after carriage costs:
479.5 tons, MCr283.889

Discussion Point #2

As Aramis suggests, we can conceive of the mass driver as a "launch tube" as found in B5.

If we assume the "25 tons" specified in the text description is the total for the mass driver, then we'd get a 25 ton system that could launch a one ton projectile.

Launch Tube for 1 ton: 25 tons, MCr0.05

If we assume the "25 tons" specified in the text description is the size of the projectile, we'd get a much larger launch tube.

Launch Tube for 25 tons: 625 tons, MCr1.25

The second option would take up all but 25 tons of "extra" space.

If you conceive of the launch tube as able to hold one vehicle as part of it, then you have 50 tons left to deal with (or enough for two ready packages). If your idea of launch tubes doesn't include space for the vehicle being launched as part of the tonnage, then there is only 25 tons of space left - just enough for another ready package to launch.
 
If we go with the larger Launch Tube option in Discussion Point #2, we won't have space for the vehicle carriage costs shown in Discussion Point #1. If we choose the smaller Launch Tube option, there's plenty of space for the carriage costs, but we still have a sizable space left unspecified.

My suggestion at this point is to go with the large Launch Tube option, and (one or two) extra space(s) for launch-able chunk(s). This doesn't leave space for the vehicle carriage costs, but this design is really B2 with (perhaps) a piece or two nabbed from B5. Were it a B5 design with B2 bits, I'd probably look at it the other way.

That leaves us with considerable MCr to devote to the Processing Bay.

Oops, I missed the bit in the text description saying the 1330.7 includes the architect's fee.

My practice is to round starship costs to the third decimal (so MCr1317.525 for cost before the architect's fee). I'll edit my design listing accordingly.
 
Final design if we use the large launch tube option.

That makes sense, but it doesn't tell us how to build a processing bay, for a smaller (1000-ton) platform, etc.
