Does anybody else out there consider the method of sweeping mines by chucking lots of small ships at them a little odd ?

Ok. Everyone does it, but do you think it is a sensible mechanism for removing mines, or perhaps a sensible idea, but the sums aren't quite right ?
Was it intended by the designers or did they just get their sums wrong ?

Consider this !

Mines are space at 1 per l.y. squared.
Now this is a massive area.
A ship (say maximum size 1000m in length) that detonates one mine would only really detonate one mine.

So perhaps it's just the reduction in the minefield size after a hit that is wrong ?

But you have to consider all the pieces of the ships and the mines that fly everywhere at warp 10 after the ship gets blown up. Not to mention these ships carry antimatter in their fuel tanks and that would make a big explosion as well. What's a little strange is that an exploding ship on the battle board doesn't damage any ships near it.

Very Happy To believe the unbelievable you have to have faith. You have to separate reality from game fantasy. Stars! is not a simulation of reality, it is merely a strategy game. Therefore the world of Stars! is quite different from real world physics. There are no size measurements of ships in Stars!. Ships are measured in mass not meters? Planets are not ruled by gravity. Colonists live without oxygen and lunch. And where have you ever seen a plumber in Stars! anywhere? Very Happy

Also consider other such "odd" things with minefields...

Mines do not move... so how come minelayers sit in the middle... and yet the field expands

How come mini and super mine layers don't get damage by detonating mines? Surely if mines can't damage them then thay can run through enemy minefields without worry? How come one ship sweeping a minefield on the far south can sweep the mines in the far north... yet has to be in orbit of planet to attack the starbase?

And never mind the bloody plumbers, have you EVER EVER EVER seen even a single school? Are we to believe that in a universe where faster than light travel is possible there's not a single piece of information that isn't handed down generation to generation??

A minefield works under a hive mind - every mine in a minefield is linked to other ones. As soon as some are laid, all mines are pushed out to accommodate the new residents. As soon as some are lost, mines shift to fill in the gap to protect the all-important juicy center.

And mine layers are equipped with special technology which enables them to interact with the minefield's hive mind. This drives the exploding mines away from them (see bottom) meaning they are immune to their own explosions.

Bureaucracy. Do you have any idea how long it takes to get a stargate travel permit? 1 year!

As for the original objection, the answer is easy - the faster you go, the more attractive you are to mines. At warp 4, you can pass through harmlessly, not disturbing anything present. Due to the size of space relative to the size of the mines, the chance of hitting a mine that isn't actively pursuing you is infinitisimmely small. SS, because of their natural stealth, can go 1 warp faster, and SD have all their ships equipped with 'Someone Else's Mine' fields which allows them to go 2 warps faster. At warp 10, every mine in the field is after you, so you'd better duck! :duck:

What I want to know is, who are the Smaugarians, and why is one of my ships always named after them?!??!?! Mad

I think the nature of minefields is more complex to what you are describing here.

Note that all travelling ship do not actually move linearly thought the space but they make jumps (hyperspace jumps). Vessels dive into ocean of matter to emerge in other places. The higher warp speed is the greater amount of energy is emitted when emerging and this portion of energy can trigger a mine (the amount of energy do not depend on mass but only on hyper-speed). The deeper in minefields a vessel re-appears the more mines are around and ignition is more like to happen.

Guttling guns do not make swept by direct hitting a mine with bullet, but by shooting into space kind of explosive bullets which emit the energy and trigger a mine remotely. In battle, gattling guns (bullets) or laser have effective range to penetrate/burn a hull of enemy's ships (or decrease energy shield), but gattling guns have ability to shot bullets at hyper speeds when it is shot in deep space and make them best minesweepers.

Lasers also emit energy by it more condensed and a mine is swept only by direct hitting. The maximum speed of laser beam is light speed i.e. at warp 1 max, so it can't hit the mine on other side of a minefield at same year (here "hive-mind" theory can be applied).

Missiles are too dangerous for mine sweeping as explosion can emit too large energy which can damage the vessel it is fired from. Additionally mines can use jammers too (which can't be counteracted by ship's computers as the safe distance to a mine must be preserved).

Vessels which are shot down, in battle do not explode, but they lose maneuverability and hull integrity so they either fall on A planet or as wrecks remain in space (that's why salvage teams can recover minerals both in space and on ground).

Any gaps in this theory?

Some interesting "sci-fi" theories to try and explain minefields. Rolling Eyes

I realise now that trying to explain mine sweeping from an actual physical standpoint won't work. Sad
Perhaps a discussion of the physics behind Stars minefields could be in another post.

Ok. To try and get back to the gist of what I was asking.
Teleport
Do people think that sweeping minefields by using chaff is either too easy or too cheap ?
Do you agree that mine sweeping should be more difficult than just chucking a few cheap old ships at a field.
Does this tactic reduce the effectiveness of mines far below that which was intended in the games design ?

I'd just like opinions on how much you think it affects game play and whether that is good or bad.

O.K. I'll add my two cents to the mix.

First, chaff cost both resources and minerals so I don't think reducing a minefield with chaff is too cheap. If you build overlapping minefields, then chaff sweeping is even more expensive. minefields are already very powerful and shouldn't dominate the game anymore than they do already. Everybody keeps theorizing about the scientific bases to support game mechanics but let's remember, there are no faster than light ships, space mines, Big Muthas or small ships built to act as chaff in space.

If you want to draw parallels let's do it to actual military history. Mines have always been an obstacle, not a barrier. They will slow down an enemy, inflict minor losses, but that is all. And as technology has improved, they have become less and less effective over time. During the Gulf war, the Iraqi minefields barely presented any obstacle at all.

This is true in Stars as well. Prior to decent armour and shields, SD minefields rule, and non-SD minefields are very strong. As Gatlings and Cruisers start to appear, they become less powerful. By the time chaff becomes very cheap and Nubians appear, mines only slow an enemy down a little.

I know this does not explain the "Science" behind mines, but it does how that Stars minefields have a similar effect to the "real" counterpart.

One other expense of chaff sweeping, is that you have to have each chaff in a seperate fleet. In most games, by the time chaff is cheap, getting a spare 100 to 200 fleets is very difficult.

I sort of get this explanation.

You are saying that it is a natural progression of different phases throughout the game ?
Until chaff-sweeping becomes cheap enough to be just that, then it is better to sweep with (armored) Cruisers, or whatever takes your PRT fancy, and try and keep them alive and actually sweep with weapons rather than sweeping by detonation.

IMHO, Chaff Sweeping should be considered a cheat, as it involves
numbering of fleets on purpose and the other side can't really
do anything to counter such form of an attack.

Of course, that would make me to think Split Fleet Dodge is a
cheat also, but I still have to see it used effectively.

All IMHO, of course.

I disagree. Manipulating fleet numbers, at least in this case, is simply a matter of scheduling movement. This is pretty basic to operational planning and I see it as a feature of Stars!, not a bug Wink

Yes, but exactly the same technique (fleet numbering) applies to battle board overload.

Battle board overload is not the same thing as operational scheduling. That exploits a limitation of Stars! to enable a player to manipulate what fleets engage in battle, even when they are all at the same location. That is a cheat.

Manipulating fleet numbers in chaff sweeping doesn't allow you to choose what fleets will engage in combat, just the order in which your fleets transit a minefield. In real world terms chaff sweeping is like what the Iranians did in the Iran/Iraq war, sending waves of untrained conscripts through Iraqi minefields BEFORE moving the trained troops through.

Completely disagree chaff-sweeping is a cheat.

Hell, minefields only really matter, lateish game, *against* chaff.

(You don't send your mainfleet ahead of the chaff because it will *die* against their chaffed fleet, and you don't send your mainfleet with chaff through minefields above safe speed, because your *chaff* will die if you hit.)

But skirmishers will routinely run through minefields going "Lah de dah" because you can afford the damage more than you can afford the time or to let them be caught.

As has been said, minefields are an obstacle, not a barrier.

All they do is slow things down and buy time, they don't *stop* them. (SD exploding fields an exception, and those again really only against chaff, once BBs and up are fielded in numbers.)

Crash sweeping goes beyond using chaff to do it in any case.

You see the big, multiple fleet, chaff sweeps when a field has to go down *now* for a following fleet to immediately use.

Given longer time ranges you see sweepers (especially specialized designs) purposely do high speed runs into minefields. One of the earliest Stars! articles I ever saw on minefields talked about sending groups of individual beamers (BB or Nubian) into minefields at high warp - figuring that one of the five or six sent would make it far in, and then sweep most of the field.

From my POV you have four methods for getting an attack fleet through a minefield:
1. Wade through at the safe speed
PRO:
o Minimum number of fleets used
o No ship losses/damage (barring SD exploding standard fields)
CON:
o SLOW, very slow.
o Tends to telegraph your target to the opponent
o Easy for enemy to shift minelayers behind you and wall you in; this can be a very *bad* thing.

2. Charge in at a higher, potentially unsafe speed
PRO:
o Mininum number of fleets used
o Potential tactical surprise
CON:
o A minehit stops you. Kills chaff, most SFX designs, most non-B52 hull bombers, and generally messes things up. A heavy hit being nastier still depending on ship designs.

3. Advance use of sweepers. They could have "waded" in previously, or be doing a "charge and sweep" a year in advance of the main fleet. Various tactics available.
PRO:
o Generally safe for the attack fleet
o A good sweeping job might set up a potential "fork" attack.
[see below for meaning of "fork attack" if you don't know it.]
CON:
o Gives opponent notification that you're interested in that area
o Uses up fleets. And design slots if you have a specialized sweeper or skirmisher out there.

4. The classic "chaff sweep"
PRO:
o Usually safe for the attack fleet
o Potential tactical surprise
CON:
o Uses up a pile of fleets
o Chaff losses (minor, but still losses)

Option Zero of course is to kill his minelayers beforehand. OR to be playing against a Warmonger without allies or a certain MT-supplied part. Twisted Evil

"fork attack": I think "fork" is a term borrowed from chess. Essentially getting an attack fleet into a position were it can make viable attacks on multiple targets (usually planets). Usually puts the opponent on the horns of a dilemma since (hopefully) he lacks the forces to successfully defend all the potential targets simutaneously. Options abound at this point.

You are correct. The term "fork" is used in chess when two or more pieces are theatened in the same move. The classic example: a knight moves into a square that threatens both the enemy king and queen in the same turn from a safe position. Therefore, the only move for the enemy is to move the king and lose the queen.

Yep. I've been forked many a Starsy night. But I wish you would keep your forking strategy in your chess. Someone just tried to fork me this last turn. And now after reading this, I am sure there will be others trying to fork me as well. This is going to be a big forking mess now. Very Happy

Hi!
> From my POV you have four methods for getting an attack fleet
> through a minefield:
> 1. Wade through at the safe speed
I'd like to remind you to a simple fact that NO minefield can defend itself properly. Even SD minefields can be cleared very fast if there are no ships to defend them. You can afford this tactics only if you know your opponent doesn't have warships close. If he has them there, your sweepers become just sitting ducks.

> 2. Charge in at a higher, potentially unsafe speed
Highly recommended. But at the speed that will maximize number of sweeped mines.

> 3. Advance use of sweepers.
Almost always. Needs high amount of MM though, like sweeping with pairs of sweeper groups, targeting potentiall interceptors before they are launched etc.

BR, Iztok
> 4. The classic "chaff sweep"
Somewhat expensive and risky (*), but makes the best and fastest surprise attack possible. Also, there's NO defense against that kind of sweeping.
(*) You can loose all support ships by hitting micro-minefield that was left after unsuccessful sweeping. Happened to me with an exploding minefield of radius 1 or 2 in orbit of an attacked SD planet.

something about chaffsweeping detonating SD fields...

i figured out, that when you chaffsweep a SD minefield
and attack the same turn, you get the damage from detonation
even if you swept the whole field.
(i used 300 chaff to sweep a 40ly field, should have done
the job).

how can it be that still it detonates?

can this be avoided???

and as i am asking stupid questions (and am too lazy to find
out myself):

i know that if i got 2 overlapping detonating fields, the
fleets get only damage from 1 field. what if the 2 detonating
fields belong to 2 different SDs???
double damage???

thanks

I guess, that shows, that in The Order of Events, checking if
the field still exists happens after sweeping (not before
detonation - another example of Chaff Sweeping being a bug,
therefore cheat).

Quote:

If field exists (detonates) and has 0 mines, it's radius would
be 0 l.y. And detonation would happen in the circle of
COORDS+radius, what leaves us with detonation only at one point
(where the field resided).

Quote:

Nope, You still get damage only from the lower_player_ID field.

You didn't sweep the whole field with your chaff. Probably due to reduced speed in travelling only 40 ly.

Send your split chaff at warp10 beyond the planet. I think 49 ly will work, perhaps 64 ly. And if your not lazy... Very Happy
try a retest using this method and you should see different results. There should now be a fleet at the planet including any chaff that were included with this fleet, and the minefield is gone, and no explosion damage happened. Cool
Now what would happen if the minelayer race sets you to friend? Confused

I thought detonation happened before sweeping, that would explain it. I know it's immediately after movement but before production, so in defending your planet you can detonate on enemy chaff and then churn out 200 of your own and whoop his socks off. Very Happy

Crash sweeping is not the same as the normal sweeping that beams do, the crash and decrease of the minefield happens before the beam sweeping, but mabye still after detonation ...
Anyone testing that right now? Wink
