[House Rule] armour adjustments by dton range

[F33D]

This rule brings vehicles into the starship armor paradigm. In my game vehicles are <10 dtons to a minimum of 1 dton.


Figure armor factor as normal then apply the mod by tonnage.

Hull/chassis size less than 10 dtons (min. 1 dton), multiply armor points by 0.25
Hull size 10 - 99 dtons, multiply by 0.5
Hull size 100 - 2,000 dtons is no modifier.
Hull size greater than 2,000 and up to 10,000 dtons, multiply by 1.5
Hull size greater than 10,000 tdons, multiply by 2.
(round down fractional results)

Chart is useless. Mongoose Traveller already scales damage according to personal/vehicle/ship target.

ADDED:
New chart isn't needed at all. Your idea though is just more math for nothing gained really.

:lol: God, what an idiot.

Does the dtonnage/cost increase as well, or just the armor factor itself?

I don't really understand your chart. I can see one axis is volume and the other is Armour, but I don't understand all why you seem to have curved lines for what appears to be a fairly linear description. I also don't understand what the iconography represents. Your words are good, and informative. Your chart is confusing.

I don't think A and V are armour and volume because they are both on the same scale. Ship volumes go up way beyond 350. SO I've really no diea what the axes represent. At first I thought the different coloured lines represented this different multiplication factors, but there are six coloured lines and five multiplication factors so that's not it.

I understand the prinicple behind the rule. 5% of a large vessel is a lot greater thickness of armour than 5% of a similarly shaped smaller vessel. One mittigating factor could be to assume that for armoured ships the internal bulkheads are also armoured, maybe not to the same armour strength as the hull but increasing in proportion to hull armour. But then maybe that's tracked separrately by structure points.

It's obvious that the thickness of armour is going to be different between a half a megaton spherical Tigress and whatever a two hundred kay tee Plankwell is, let alone an assault shuttle.

Though representing this, besides stating the actual armour thickness, general or sectionally specific, would require a little effort.

 

[F33D]

The picture merely shows the surface area to volume ratio curve of a solid. The general basis for scaling the armor by dton volume.

Sorry for the confusion on that. On the pic, A = surface area. V = volume of the solid.

I changed the picture to better demonstrate

The armour factor just goes up, or down. It would make no sense to pay more for the exact same volume of armour material.

Or you could go back to FF&S's way and choose a thickness of armour then calculate it's volume.

Your idea is simpler and there's a fair bit of simplification in FF&S's way of calculating surface area and volumes as the shape of the hull changes but FF&S's way offers a consistent between vehicles/small craft/ships of different sizes and gets rid of the damage scaling that Mongoose uses which I personally don't care for.

Yes, FF&S's was far more detailed/complex and like much of its rules, very unpopular.

Unlike MGT, hull material in my rules radically changes at the end of TL 9 as there is no way that soft materials like Titanium could be made thick enough for even basic protection from particles in space of up to 0.5 grams. That necessarily makes obsolete any current day weapons (excepting nukes) if they go up against ships. Only nukes and ship type weapons can effect hulls.

Which is the trouble with threads like this, taken in isolation and out of the context of what appears to be a hybrid system that only you (and your players?) have access to, it's really hard to actually comment on your ideas.

As for FF&S's popularity, if you're going to publish your rules for sale I can see why this might be of concern, from the point of view of improving your own house rules that precious few people will see, i.e. they're off the bottom end of the scale in popularity, it's not at all relevant.

Will you be publishing?

The rule I propose is self contained and contextual as it can be dropped in without other changes.

It's very relevant. Why would you want to introduce rules for your players that have already been proven very unpopular with players??????? :?

Then go ahead and drop it in and don't ask questions of the rest of us.

If your players don't like it then fair enough, there are some of us like the detailed tools to construct the setting so that we don't have to house rule a popular rule book.

I can ask what I want you little punk. Now, drop dead or practice trolling elsewhere.

Would you really talk to me like that in real life?

I think not.

No. You'd be on the floor unable to hear anything for trying to dictate who I may communicate with.

 

[Anonymous]

Really?

You're threatening me with physical violence?

Where do you live? Let's meet.

I'd take this to PM but I can't, you don't allow members to PM you. Why is that?

 

[F33D]

Really?

Yes, I am honest. I never threaten btw.
