While the system gives you a good range of sizes to pick from, from SM+4 up to SM+15 but... what happens in you want a ship bigger or even smaller?

Well, wonder no more!

Below is a extended hull table covering ship sizes from a partly SM0 all the way up to a massive SM+31!

Of course how boring would it be if I just gave you the same data the books do? So I figured I'd throw in a few extra tidbits you guys might find useful. Since

*on pg. 9 lets us know that the ships were figured as unstreamlined cylinder I used that data to give you not only the radius of the ships end caps but the ship but in another table below I also show you what the volume and surface area for a given SM is!*

Now just in case this expanded table is not enough for you (and let's face it, might as well push things as far as you can go), it's pretty easy to keep it going. As you might of noticed, everything follows a nice and neat pattern of progression.

The ships loaded mass follows a 1-3 progression increased by a factor of 10 every time the pattern repeats.

Length in yards follows the every versatile SS/R tables progression of 1, 1.5, 2, 3, 5, 7 and 10 with the pattern going up by a factor of 10 every time it repeats.

The radius in yards is equal to the length/10.

dST/HP follows the same sort of 1, 1.5, 2, 3, 5, 7 and 10 pattern as the the ships length.

Handling goes down by 1 and SR goes up by 1 every three changes in SM. SR can not go higher then 5.

The ships volume is equal to 100 cubic feet per ton of mass.

The ships surface area follows a 3, 6, 15 progression which goes up by a factor of 10 every time it repeats.

Eh?

What's that?

What if you want to be a non-conforming special snow flake and ditch the 1-3 progression so you can make a ship that's, oh I don't know, 2 or 50,000 tons?

Oh.

That's all you need?

That's easy!

Now for most systems so long as you know the ships loaded mass you're G to G but there are a few systems that need to know the ships SM to work and in general you are going to need to know what SM the odd sized ship fall under.

To figure a ships SM use this formula: 2×Log

_{10}(ships loaded mass)+2. Round up to see what SM your ship falls under but use the full fractional number (though rounding it to 1 or 2 decimal places wouldn't hurt) to figure the stats of systems that work off a SMs,

To figure its length in yards use 15×(ships loaded mass/30)

^{(1/3)}. Radius is 1/10th of the ships length. Surface area can be figured by converting length and radius to feet and figuring 2×π×radius×length+2×π×radius2. Ships volume is its loaded weight times 100.

And what they hey, what if you want to figure the ships loaded mass from its SM? Piece of cake. Ships loaded weight is equal to 10

^{((ships SM-2)/2)}.

But wait! There's more!

What's the point of giving you more ship sizes to work off of if I wasn't also going to show you how to expand the systems you can load onto said ships to follow suit?

Below I will show you how to expand the various systems in

*to fit into any sized hull you want. I'm only covering the systems that have stats that change with SM (for example I don't cover Reactors since the amount of power points they gives does not change with SM) and I only cover systems from the first*

**GURPS Spaceships***book. I fired my brain trying to unwrap one book thank you very much heh but I will get back to systems covered in the future books in due time.*

**Spaceships****Cost**

This is pretty simply. All costs follow two price points, one for odd SM systems and one for even SM systems, that repeats increasing/decreasing by 10 every time the pattern repeats. For example SM +5 Steel armor costs $6,000 dollars and SM +6 costs $20,000 dollars so if I'm right SM+7 steel armor should costs $60,000 and if we look it up on

*pg 11, yep, that's what it costs.*

**Spaceships**So for a quick way to work out what the cost of a system of any size is to subtract subtract 5 from its SM is your ship is an odd SM or 6 if its an even SM and then divide the difference by 2. Then raise 10 to the power of the remainder and lastly multiply the exponent by how much a SM+5 version of the system costs if odd or by how much a SM+6 version costs if even.

*.*

**Example: To figure the cost of a SM+22 fusion rector first we subtract 6 from its SM since its an even SM getting a difference of 16 which then halved to 8. We then raise to to the power of 8 or 100,000,000 and then multiply that by the $1 million cost of a SM+6 reactor for a total cost of $100 trillion****Workspaces**

The number of workspaces a system needs is the same for a given SM no matter what system it is.

Number of workspaces is equal to ships loaded mass/10,000.

**Armor**

dDR: Ac×(ships loaded mass/30)

^{(1/3)}. Round numbers off to match a 1, 2, 3, 5, 7, 10, and 15 progression.

Ac is 0.33 if ice, 0.5 if stone, 1.5 if steel, 2 if light alloy or organic, 3 if metallic laminate, 5 if advanced metallic laminate, 7 if nanocomposite, 10 if diamondoid, and 15 if exotic laminate.

If your ships is streamlined then use the weight of a ship one SM smaller.

Of course since I gave you guys the surface area of each size of ship some of you are going to want to play around use the greater range of options that the

*and*

**Cutting Edge***systems give you. In that case remember that each system of armor only covers 1/3rd of the ships surface area.*

Nice work, really really be nice ot see this in a Pyramid.

ReplyDeleteI've been getting this a lot lately heh. I do have some Pyramid plans in the works but the ones I got in the works are originals.

DeleteOnce I can start moving forwards with them I'll see if they'll be ok with me using content on my blog as article fodder.

Combine this, your post about missile, and the current post about power cells, and you've given me the tools to answer the questions I was about to ask.
