Would Minefields Work in Space?

[@theishiopian68]

Personally, I love the idea of self-propelled mines. These are basically just modified torpedoes that sit in orbit. Essentially undetectable, as unless their engines are active they give off almost no heat. However, as soon as they detect hostile movement, or perhaps if they are triggered remotely, they lock on to the nearest heat source and fly in swarms towards the target.

[@patbracken]

Spacedock mentioned missiles loitering in space with passive sensors, which is my favorite sci-fi minefield type.

A thing we have now that science fiction writers didn't really think of too much is what's called a loitering munition, basically a suicide drone that can hang out in an area for an extended time waiting for a target to appear. That fits the profile of what most space mines seem to be, but the term hadn't been invented when a lot of this science fiction was being written.

Ive always loved Galaxy Quest and was dying all video waiting for it to come up It is my favorite use of mines in video media because the movie doesn’t try to explain why the mines are located where they are. Whatever strategic purpose they served stopped being relevant long ago when the Great War ended and the remnants of the field is so expansive and dense it appears to be a dust cloud. A folly so many shows and movies fall into is trying to justify the reason for somethings existence when explaining what something is when narratively it does not matter and only raises more questions

[@DrakeAurum]

An aspect worth exploring (but rather grim and gruesome) is the way that real-world mines are designed to do more than just immediately detonate and take out a single target. More modern minefields are designed to not even go active until people / vehicles penetrate well past their perimeter, so that once their targets do become aware of them tjhey're already pinned down. And in some cases, mines are deliberately designed to be more likely to cause crippling injuries rather than kill outright, because killing a soldier leaves their squadmates free to continue their mission, but injuring a soldier results in other soldiers needing to tend their wounds and try to carry them back to base. Likewise, a minefield designed to disable a ship will leave it stranded and in need of rescue by others, creating a high-tension situation that can easily span an episode.

[@littlekong7685]

It is a bit of a myth that mines are designed to main not kill. Some mine,s like the Russian leaf mines are main mines, designed specifically to main civilians in urban and rural settings to demoralize a nation. But most infantry mines are built small simply because it makes them cheaper, lighter, and harder to detect. Kill is the secondary goal, maim is a nice consolation, but most minefields are about area denial and locking an assault force down to be swept by the defenders. Many nations have placed signs with zero mines in the supposed "field" simply to deny an assault force a fast avenue of approach.

[@EcardEcardian]

Mines are there to stop advances. They are a denial tool. This thing that mines maim / kill, that is just a bi product of the denial part.

@@littlekong7685 Have you been at a National guard training or in the military? Maiming is very much a valid way to take out 5 soldiers out of the fight at the cost of one heavily injured. There was an excellent 23 minute drone video on Telegram showing excellent Ukrainian medic training. A group of Ukrainian soldiers were trapped in a petal minefield, most heavily injured. The medics tried to stabilize the survivors but also stepped on those mines, resulting in removal of limbs. 2 Bradley IFV's were used as medevac one of which was, sadly, later taken out by an ATGM. In the end the total number of casualties (WIA/KIA) i counted was 12 soldiers and 5 medics on video, probably more, as the FOV of the drone was rather small. For a small-ish field of green petal mines. This was during their failed counter offensive on Russian lines. Also, it wasn't the Russians who used petal mines on civilians, but Ukrainian forces.

[@littlekong7685]

@@jkl9984 Area denial is the design goal of a minefield. Training manuals (publicly available) state the goal of a minefield is to control an area and blunt assaults against a defended position. Majority of casualties should come from fire support of the minefield not the mines themselves. And no US minefield should be created outside of a fire control area as this achieves no operational support and without cover minefields can be (relatively) easily removed or avoided. Yes, under fire, inside a minefield casualties can easily stack up, and it is always good to take advantage of an enemies paralysis and reduce equipment counts to deplete enemies fighting abilities, minefield or not. Why would the Ukrainian military launch petal mines onto Ukrainian civilian areas inside their area of control, civilian transport hubs, and into Ukrainian military supply routes and depots? that seems pretty self defeating...

The Traveller TTRPG bypass a lot of issues about space mines with of CAPTOR (Captive Torpedo) Mines. In summary, a mine is just an bunch super-cheap of antiship torpedo lauchers linked to a cluster of IFF transponders and a manuver engine. If a ship comes close without proper traspoder codes, the mine fires a salvo of torpedoes, eventually repeating until it runs dry. The genius of the system is that the empty mine can be either rearmed or discarded, since it's very, very simple tech.

Both vertically and horizontally. The pursuing went face first into the field, with half a dozen dreadnoughts coming out burning wrecks.

[@Starwar111ITA]

Something I've not seen explored is the fact that, in a more realistic sci-fi setting, one could use mines by focusing on certain orbits and basically locking down certain approaches or departures to and from spaceports. We're assuming that the ships can't just start or complete their journey by travelling through the atmosphere for longer periods of time (but they could be stopped by lack of fuel, or risk interception en route). Also, since things like interplanetary transfers need specific orbits and dates to achieve transfers (and if fuel is a concern ideally one wants to reach a particular station/ship/base for refueling in one motion), one could use space mines to pre-emptively lock down these routes, potentially stopping trade or a big enemy fleet from reaching a planet.

[@DanielLCarrier]

The problem with that is you couldn't have a permanent minefield, since you can't make them orbit in such a way that they'll be along the orbit at the right time every time they can do a Hohmann transfer. You have to put them in an orbit where you know they'll intersect with that transfer. And then they can avoid it by using a slightly less efficient route at random.

[@thebravegallade731]

This actually works even better in more unrealistic ones too. Specifically any setting where there are things resembling hyperspace lanes. Have mines on key chokepoints in the lanes...

[@battleoid2411]

​@@DanielLCarrierYou could potentially seed the most efficient transfer routes with loitering missiles in such a way that the mines all converge when ships are most likely to be there, then an approaching enemy knowing that's likely the case will be forced to either take losses or use up precious delta v, of course executing that would require some extremely accurate Intel on when, where, and how enemy ships are approaching you.

One trick I haven't seen in any science fiction, but have seen in another channel discussing ideas like this, is just filling the orbital space of a target planet with a ton of ball bearings or something similar. Instant Kessler syndrome. It's also self sustaining as anything the ball bearings destroy becomes more debris you need to avoid or clean up. You've successfully denied access to the orbital space of that planet and it's a huge hassle to clean up (though not technologically challenging - if an alien prankster pulled that on Earth, we could probably escape with a few decades of effort at most)

[@Andy_Pengwin]

The sequel to The Mote in God’s Eye (The Gripping Hand) did something like this, but in reverse. As the human ship was fleeing toward the fixed jump point in the system, the Moties essentially “flung” all sorts of debris at the jump point on a trajectory to intercept the human ship and either force a collision, or confuse the ship’s computer enough to force it to miscalculate.

[@MonkeyJedi99]

This was done on a smaller scale (to take out a specific space station) in one of the later books in the Dorsai series. - My sci-fi TTRPG players used the idea once. They had sensor-confirmed spy data on the real-space arrival point of a fleet of bad guys and set a whole lot of asteroids and space junk on three converging orbits timed to pass through that space just as the enemy arrived. I skipped doing a lot of math and just had the tactic take out about half of the arriving fleet and make the planet dangerous to approach or leave until they (and whatever space transport from the planet survived the battle) spent weeks working to scoop up their mess. - They were psyched to have their trick work, but they hated the downtime of clean-up so much they never did it again.

[@Kurell171]

Extremely renowned, intelligent, and handsome rocket scientist here. From my highly qualified considerations, I can definitively say it would be very hard to get the amount of material needed for that in the first place, But more importantly, deploying it is an issue, because the ball bearings will always pass through the same point they were launched from, so they could end up destroying the craft that's deploying them, especially since you have to launch them in different directions so ships can't just match the velocity of the bearings. In addition, if a society is advanced enough to lead interstellar wars, they'd probably have a fleet in a higher orbit, and cargo could be launched via a magnetic accelerator, which would allow it to be armored. It would be an incredibly effective weapo, tho: let's say our ball bearings have a radius of 10mm, so a volume of about 0.5cm^3. The material of choice would probably be iron since it's the most abundant metal, which has a density of 7.8 g/cm^3. So our mass is about 4 grams. In low earth orbit, an object has a velocity of about 28000 km/h or about 7.7km/sec. So each of our ball bearings has a kinetic energy of 1/2*0.004kg*(7700m/sec)^2 = 132kJ. For comparison a 50cal bullet typically carries around 25kJ of kinetic energy. I think it's sort of like a Dyson sphere. In concept brilliantly simple, but pretty complicated to actually achieve in practice

[@ianglenn2821]

@@Kurell171 what a coincidence, I am also an extremely renowned, intelligent, and handsome scientist. I would just like to remind you of the importance of relative velocity for calculating the impact energy. If a ball bearing is at orbital velocity and it hits something at a slight angle that is also moving at orbital velocity, their relative speed might only be a few m/s. Of course, even 100 m/s could be pretty damaging. The closer the orbits, the less dangerous the impact. So, if you got something going in orbit the other way, then you can double your speed, the relative impact velocity would be 2 x 7.7 km/s, almost 475kJ of impact energy.

The only issue would be field maintenance, in a couple decades, a century a most, there would be clear areas in the orbit. Maybe that is the goal though? Lock a planet down for a decade while your fleet assembles or rebuilds. Or as a judiciary decision by an intergalactic government as a form of temporary sanction.

You can clear a minefield by slowly advancing and triggering them one by one, letting your PD clean them up, but there's also cooperative mines that trigger the entire minefield when you get close to just one. The best part though is that the mines use an IFF system to avoid triggering on friendly vessels, which means if you're sitting in your own minefield and a stray shell knocks out your antenna, your own mines will suddenly see you as a target.

I'm surprised no-one else mentioned it.

It doesn't make sense to have them always deployed, but it acts as a good deterrent for ships trying to get close when they are. Also, they don't follow in a neat minefield, rather just circling the mothership and focusing on any ship that gets nearby. It accomplishes a similar goal to a static minefield, while also being a lot more practical, and, of course, mobile. I've also found they're good at dealing with enemy fire, because they're another, usually closer, target to hit that wasn't my ship. And, the debris from it, if they blow it up while it's on an intercept course, can still be a hazard.

[@fatcoyote2]

I think that the "best" way to utilize the concept of space mines is when the universe utilizing them has factors that predetermine the paths that space vessels will use, like jump gates or star lanes. Also, the mines must either have an exceptionally large area or effect or way to propel themselves towards a ship once activated. I can't remember which series I watched had them, but one version effectively turned the whole thing into a claymore that would explode themselves outwards after maneuvering into better positions, launching dozens of spears in a directed cloud like a massive shotgun. Other mines would do likewise, filling space with near undetectable rods of metal hurtling at near-railgun speed in multi directional clouds of projectiles which only needed to land once or twice to seriously damage any ship.

[@BlenderGeek]

Teliporting a mine into a ship, then moving the ship around the mines thusters is a genius idea.

[@martytheanimator6426]

The mines in Star Conflict vary from a cloud-like swarm of defensive mines that looks more like a bunch of hard to spot dots clustered around a frigate to singular mines placed by light scouting craft. Then theres cloaking mines deployed via gun turret by destroyers, which cloaks and arms after a short delay, but also homes in on enemy vessels passively. All these mines can be used offensively to varying degrees, but are more defensive in nature. And then theres a task specific mine attached to a warp gate but the quest dialog also sometimes refers to this device as a bomb instead, so its not exactly clear if it is a sort of proxy mine or just a bomb with a timer. Also the "alien" faction ships the player can pilot can deploy mines which seek out enemy units within a given detection distance.

[@alasiadarthe001actual9]

Depending on technology level you can do area denial with lots of micro asteroids or even debris in a planets atmosphere. Shards of broken ships asteroids or anything can damage a ship even more so if the objects can be propelled at the ship.

[@thethan302]

There’s a mission in the original X-wing, where you have to destroy a minefield in an A-wing. These mines are basically nothing more than automated turrets. Flying into its range causes it to target and fire at you. And there’s like 35 of them. Really mines work on a small scale. Protect a location like a buoy, a TFL entrance point. A wormhole; things like that. Trying to mine the space between us and mars is rather out of the scope of reasonable use.

Personally, the only sci-fi mines I like are the seismic charges used in Star Wars (because who doesn't love that moment of silence before they go off). Otherwise, chaff and flak missiles work just as well and can be designed much simpler than mines. The missiles can be designed with mechanical fuses, meaning electronic warfare equipment can't interfere with them. Plus, by physics, flak can just remain in a single spot and wreck havoc on any ship that passes through it. And chaff works best if one is being pursued, as the enemy likely won't have time to dodge the debris depending on how close they're chasing

I think Nebulous has a great example of mines. Mines are deployed via self propelled rocket containers into strategic locations. Some are typical magnetic mines whereas others are sprinter mines that will initiate a boost phase when a ship is detected, so basically the same concept as stationary missiles from earlier in the video.

[@dereksherwood3794]

To avoid the monstrous logistics problem of needing infinite numbers of the things, you could mine lagrange points between celestial bodies that you're trying to control access to. There's only something like 4 or 5 points for each pair of objects, so the area you'd have to cover is much smaller and easier to monitor. Key locations on common transfer orbits between locations you're trying to control would be another sort of 'choke point' relatively speaking. Combine that with mines that project intense radiation blasts, or "mines" that are more like railgun platforms, and you've got some reasonable military options.

[@isaacgraff8288]

an idea for space mines. repurposed missiles. Give them functional sensors and you're practically done. "any ship enters X range, chase down and blow up." Gets rid of old missiles that are just taking up space somewhere. Continuing that thought, if a faction needs to put a bunch of missiles somewhere and don't have the room in their normal warehouse, modified mine field. Have a code that you can go and acquire a few of your missiles that are just chilling in space. If someone doesn't have the code the missiles you made go and do their job. There is plenty of space in outer space.

I think you hit everything on the nail on this one. Even great comparisons to reality with both naval and aerial mines/ barrage balloons as well as going into the use cases. Something I wonder though is would you consider a form of kinetic mine that is effectively a bunch of ball bearings in orbit as mines? It is most certainly a form of aerial denial especially in the more hard sci-fi settings.

In a Sci-fi series I'm working on, a key battle used stealth mines, where they are coated to reduce their signature and are nukes. How they work is that a vessel would normally get caught on one of its wires, which will cause the mine to swing around, hit the ships, then explode to launch jets of plasma and melt metal into the target and nearby ships.

Same thing in the Lost Fleet series by Jack Campbell. Mines are pretty much exclusively used at system jump points and occasionally at their artificial "Hypergates" and are also combined with tactics such as fleeing along a specific vector to goad pursuing ships into the minefield. But FTL location restrictions like jump points, various flavors of "gates," and wormholes are all major solid justifications for mines in sci-fi settings.

I thought a lot about mines for my Guardian of the Stars setting. While a mine more on terms we think of them is really only useful around a planet at most or some very fixed location, true mines in space are most likely a specialized stealth missile with a relatively small range that sits 'in place' until it detects a hostile target. A sudden launch from 'close range' (for space) is fairly hard to deal with, which let's them act as a area denial tool. You still need quite a lot of them to make it work, but it can work. Advanced sensors in turn are the answer to mines, letting any vessel with good sensors act as a 'mine sweeper'. It also makes recon vessels useful.

[@GoodOldGamer]

"And what you fail to realize is that my ship is dragging MINES!"

[@MrQuantumInc]

Weaponized defensive Kessler syndrome. The mines don't need to have explosives or station keep or have any moving parts or really parts, just tiny bits of metal moving at orbital velocity. Shrapnel stays in space indefinitely, thus shrapnel from any explosion is a space mine. Unless they happen to be in a similar orbit, the enemy will hit the fragments at incredible velocity. Activate countermeasures would struggle to even detect a relativistic kill missile, but fragments don't need to detect anything, and the extreme velocity would just make a metal fragment hit that much harder. The world ending RKM would just turn to a gas cloud in the middle of your "minefield".

[@beor2193]

Just wanted to say the same thing. A possibility for space mines would be the Kessler syndrome, just blowing up junk, asteorides or the surface of a moon or planet to shower the expected path of a spacecraft with debris for area denial, perhaps even accounting for its potential turn rate. Like up to area of effect dust guns or macrons on the higher end of the technology scale. Even the potential Kessler syndrome, rigging up stuff to kick of the cascade on demand would be pretty bad, and potentially able to go out of control, but for long lived races or those with sufficient technology it could be used to lock planets in or lock visitors out or, as @MrQuantumInc says, even potentially soak incoming fire. Perhaps even set it up in a way that the junk eventually achieves escape velocity, fall back or form a ring to deal with the aftereffect.

[@W4kT3k]

In the original Battlestar Galactica series, they had to navigate through a Nova that was mined. Two Vipers were specially armored to protect them from the heat, but the protection blinded them from locating the mines, so they needed computer assistance and basically fired blind.

[@forlogic53]

I think just spreading random debris around space just forces any form of spacecraft to go around it or have to slow down to avoid colliding into them. Then you can set up overwatching turrets on key areas and have them watch over the debris field. Just slowing down spacecraft is deadly enough, assuming humanity have highly developed their space travel capabilities then their weapons would be far more advanced than what we have now too.

[@Edge-wx7hv]

in my Mass Effect-C&C crossover, a common orbital-specific area denial weapon is what I call a Kessler Barrage, basically, a bunch of cheap fragmenting warheads launched at crucial satellite and station infrastructure, meant to saturate kinetic barriers, thus opening a normally shielded target to impact from more shrapnel, and even the stuff that gets deflected still poses a threat. it's pretty pyrric as area denial goes because the resulting debris swarm threatens everyone equally, and takes months or years to clean up, but if you're using a Kessler Barrage, preventing collateral damage is pretty low on your priority list

I remember the seeker mines from Freelancer. Rear facing launcher and it would fly towards the first target that entered its range, making it great for getting a hostile off your tail. But it lacked an IFF system so if the hostiles avoided it friendly fire could insue if allies are involved and fly too close. Said seekers could also lock on to the craft that launched it if you missed and doubled back. Great to usle when caught alone but a liability if there are any allies in the area.

[@cybernomad5971]

I think the largest part of it has to do with the setting it's in. For example, in a game called Rebel Galaxy, there are mines that I think are drawn magnetically to the hulls of ships and have an EM charge when exploded so it messes with the engines so you can't warp away for a period of time. As for application in a theoretical real world, it is largely situational, but I believe space stations would need regular resuplies from external sources leading to regular routes. Depending on the timing, the first handful could be passed off as accidents. It can also be used defenseivly if a station under attack can churn out as much as possible like interstellar chaff to slow down opposing forces, and if successful employ minesweepers after for cleanup

[@PavelPastushkha]

In a science-fantasy setting of my own, the space mine warfare takes form of mine-rockets. Essentially: a launch container (or sometimes four launch containers) with space-to-space missiles, usually medium range (hundreds of km), equipped with a 360 deg FOV passive infrared target acquisition set programmed to ignore the sun, an RCS unit for orientation control, IFF apparatus, and a radio rangefinder to verify if the target is within range of the missile. That, plus a solar panel to power all of above perpetually. Mass of entire unit is between two and ten metric tons as laid, and the process of "laying" said units is done by tossing them into desired orbit and position out of a ship. Such ordnance is especially popular among triads, warlords and some pirates, who lay mine-rockets "ahead" of their target, on an intercept trajectory. Mine-rockets have been used in major interstate conflicts, but are widely disliked by military, both due to being considered a coward's weapon and the fact that once they are set, they are out there for decades to come, waiting for a target, which they won't be picky about - much like anti-personnel mines in real world.

[@WUZLE]

Mines in the old Starfire tabletop game were short ranged missiles that floated quietly until they were triggered. They were deployed in patterns, each pattern being fifty mines. They were almost exclusively used around warp points, the idea being to confine ships that come through the jump point to the area around the warp point. Eventually anti-mine missiles were developed but early on all you could do was sweep them with point defense (for which minesweepers with strong defenses and massive point defenses were used) or just sacrifice ships to clear a lane.

Something that's occurred to me that fills the *role* of a minefield, and is extremely cheap (and destructive); Kessler Weapons. Explosives? Pfah, who needs those? Just fill an orbit with [stupidly large number] of grains of sand, orbiting in opposing directions. Too small to detect, too fast to dodge, too numerous to avoid, so cheap to use that it's hardly worth worrying about. Until, of course, you need to pass through that orbit without being hammered by thousands of hypersonic projectiles.

[@cmedtheuniverseofcmed8775]

In a realistic setting where the mines never move, no. However, the concept of homing mines does work. They can be set in space to float and when a ship gets into range, the engines can activate and head straight to them. Even in naval warfare now, mines consist of many things. The favorite is one is a Soviet mine that lies at the bottom. When the ship crosses underneath it, it launches a torpedo straight underneath it. Mines in space warfare is about giving range. So, yes, I agree with Spacedock. :)

I really like the idea in the Book "Deep Black", I recently read. Because of the FTL-Travel-Logic you roughly know where a spaceship will appear in a system (more or less).

Be able to take off at least some of the technology of a spaceship at the start of the battle can give you a headstart for an upcoming ambush or battle.

One of my favorite examples of a Sci-FI-ish space mine is in a game called Treasure Planet: Battle at Procyon…where the empire and the Procyon both have minelayer ships. They are HARD to see and can “swim” towards nearby ships. Some ships have point defense systems which alert you to their presence…but strangely enough, fast ships tend to be more vulnerable to the mines in that game. They can do serious damage and completely swing a battle when used correctly.

[@MazokuJun]

If you want less mines you can do tethered mines. The tethers are harder to detect but as long as they are designed to be strong enough to withstand the average or estimated top velocity of the crafts flying over them, the tether can get hook on to crafts and the mines pull themselves towards the craft by retracting the tether. Have something like 10km long tethers and you are good to go for large areas of denial. In higher velocity locations the tethers can act as wire cutting the crafts directly as well.(hyper velocity impacts)

[@Just_Lars]

[I just watched till 3:29. sorry if this turned up later] The term you're looking for is probably "loitering ammunition". In our wourld, under this term falls stuff like 1-way-drones that, once deployed, "loiter" inside the airspace until they get locked onto a target (or find it themselves) and automatically track and attack said target without further interaction by the operator. They are limited by the time they ca nspend up in air tho, usually between 5-15 minutes. In space, this system of loitering ammunition would be infinitely more effective, since you're basically limited by size, and you don't need a constant flow of energy to "keep them flying". Those mines could be laid out at strategic points, like the one where ships can leave/enter a system (if applicable), wait months or even years until someone arrives and if it's friendly, just stay passive. But if whatever enters the system is an enemy, they activate their rocket booster and bring their payload directly into the target, leaving basically no reaction time without endangering your regular defence troops.
