What are the possible CDD speeds in a interdiction field?

Interdiction field systems serve for the purpose of blocking, within certain distances, the usage of hyperspace fold engines, certain forms of FTL travel based on subspace bubbles (like the CFS does) and prevents the use of transposition and directed fold cannons within the affected area (if the ship with a transposition weapon is inside an affected area, it would also be unable to make use of the weapon).

Now, CDD/CFS units have the note that they can function inside an anti-FTL area such as the interdiction field, but there's no mention of how well, especially in regard of speed (I assume the shielding, stealth and weapon options of the CFS remain more or less intact even then). How fast can a CFS-propelled vessel be expected to move within an interdiction field?

Is it percentile based? 0.02% of normal speed? (the Sakura would have 60c, the Miharu would have 38.4c... and that at maximum field power - AS-7 torpedoes would have 3c).

Heh. The Mindy is better off using its STL thrust. ^_^;

Or is it more like a ceiling speed much like nebulas (in which CFS vessels tend to be limited to below 10 000c speeds)... like, cannot exceed 8c or the like?

Having some remaining FTL capabilities allow for the possibility of dodging a wide area attack like the blast from a Sakura-class' aether shock cannon. It also allows to close the distance (often calculated in AUs) in a more manageable manner. It'd also shorten the times each vessel has to just move toward each other

While it does leave the Star Army of Yamatai vessel with a great mobility advantage... the Mishhuvurthyar almost outnumbers them 4-to-1 against. It would explain a lot about the SA's ability to resist the SMX (and how the newer SMX gunships and scoutships, being designed with CFS systems, are more trouble to contend with)

Also, Mishhuvurthyar quintessent hyperspace torpedoes function on fold technology with a bit of STL mingled in rather than CFS technology. This would make them rather cumbersome to use within an interdiction field... or, perhaps, not at all useable?

My current assumptions for the Miharu plot:
- CFS units when inside an interdiction field function at 0.02% efficacity. Similar deal with CFS propelled ammunition or power armors (whom are better off with STL in those instances).
- Transposition/directed fold weaponry does not function if either the attacker or the defender (or part of the zone of effect) touches an interdiction field.
- Fold drives and fold-propelled weaponry do not function at all inside the bounds of an interdiction field.

The way you're doing it sounds fine to me, and I'll support it as a SARP-wide standard. Weaker anti-FTL fields might have different percentages, though, (0.05% ?).

Sounds good to me. I suppose the actual range and scale of the impact could reflect how good the Anti-FTL field is (perhaps the CFS systems of faster ship or bigger ships could have more of an impact on this - Melisson's ship stands as one such example).

You know, the way CFS FTL speeds are, travelling through a star system is a breeze. At 9000c, the Miharu crossed, under a second, over a quarter of the radius of the Tsuyosa star system. Seeing that 9000c is barely tapping 5% of the Miharu's top speed... it's somewhat scary considering the speed ships like the Sakura can reach. Almost over the top.

But wait, we had that debate before - about insanely high speeds. Nevermind.

Who ever said that the strength of an inderdiction field is constant throughout the affected area? The strength of such fields typically varies inversely as some function of distance from whatever is creating the field; typically inverse-proportional or inverse-square, but nearly always inverse-something.

Do interdiction fields work in areas where TFCs have recently been fired (i.e. TFCs are fired shortly before the interdiction field is present)?

On a side note, would this kind of interdiction field affect space-time distortions, such as wormholes or Alcubierre warp bubbles, using exotic matter rather than subspace/hyperspace, and do they affect TTDs or similar devices?

I agree with Xerena, fields will almost always increase in strength exponentially the closer one gets to the origin.

I would assume the closer one gets to the ship projecting the intradiction field the less effective FTL would be until it reaches the point where the FTL bubble or whatever is entirely dispersed.

Okay, but are things like wormholes or Alcubierre warp bubbles that operate entirely within "ordinary" space-time and don't rely on any fancy subspace/hyperspace business affected, and if so how?

As a note, all of the functions of the CFS system (weapons, shields, stealth, and propulsion) all operate from the same system and if one aspect (propulsion) was affected I fail to see any reason all of the others would not be affected likewise.

On the exotic matter (i.e. the ones that use negative energy to maintain the field V the ST method), this setting does not, atm, have the granularity to distinguish the two types of FTL to really answer the question.

What about the effect on non CDD/CFS FTL systems?

Example, the Yggdrasill uses Hyper Pulse to attain 67,000c. Would the Ygg be limited to 0.05% (13.4c), or dead in the water?

My current assumptions for the Miharu plot:
- CFS units when inside an interdiction field function at 0.02% efficacity. Similar deal with CFS propelled ammunition or power armors (whom are better off with STL in those instances).
- Transposition/directed fold weaponry does not function if either the attacker or the defender (or part of the zone of effect) touches an interdiction field.
- Fold drives and fold-propelled weaponry do not function at all inside the bounds of an interdiction field.

Personally, I prefer Kotori's estimates.

None of these numbers reflect that a gravity field has a decaying strength the further away from the point of origin that you get.

Yeah, but they make life simple. The SARP isn't hardcore on heavy game mechanics; the SARP mechanics are more like a board game--simple, easy, and predictable without big formulas.

So then I can assume there is some discression on the effect of anti-FTL fields when proximity is involved?

If you're far away from an Anti-FTL ship, then I'm okay with you tweaking the numbers a bit to make it make better sense. For the most part, though, this shouldn't be that big of a deal.

Personally, I'd go for absolute values. I don't want to have us all grow crazy from exceptions.

That may be fine for GMs that don't want to go into to much detail but not everyone wants to do that.
