Halo taught me that you need both: energy weapons are more efficient against shields and kinetic are more efficient against armor. Although in Stellaris it's the other way around.

[@23AlexandreJ]

In a more realistic scenario, it would come to witch type of weapon against which type of defense. Eg, lasers are bad against mirrowed armor; kinectics are bad against deflector shields, etc.

[@Nostripe361]

Using both is my favorite style. There are many reasons you need both. As you maybe shields are weak to one but armor weak to the other. Have different countermeasures that can negate one or the other. Even just have some environments screw with one or the other is

[@gokbay3057]

My general preference is kinetics (well, electro-magnetic accelaration. Though I can accept straight up ballistics as CIWS as well) as main anti-ship guns and lasers as point defense (plus missiles for both roles) (somewhat influenced by Children of a Dead Earth) But depending on your tech level and what technologies you have in your setting you can easily justify whichever is used or even both being used simultenously as anti-ship weapons because they have different strengths (especially if you have shields and one is better against shields and other against armour as you mention and is the case a lot of the time).

[@warmachine5835]

@@gokbay3057 there's also social and doctrinal concerns, such as how the tug-of-war between offense and defense played out for the culture that made the weapons. For the Halo example, the Covenant had a religious reason for their preference for energy weapons. Given that we can just make things up in fiction, I think using "soft" factors to justify a group's use of a weapon and then presenting a counter-example of a group that came to the opposite conclusion in the same setting is one of the more alluring ideas.

[@FGMagala]

It's really ironic that artificial gravity is everywhere in sci-fi, except to be used in any way except to keep things stuck to the 'ground.' I mean, imagine a mothership that fires extremely powerful lasers or railgun rounds, and a forward observation ship that uses artificial gravity to bend the shot closer to the target to increase accuracy? Or gravity missiles that turn ships into micro-black holes for a few microseconds. Sci-fi authors always seems to want to invent something completely exotic rather than simply applying their existing technology to do the same thing.

[@telestobreakerofgames1033]

One of my favorite examples of Energy vs. Kinetic weaponry is found in the Space Battleship Yamato. It's primary armament is Positron Shock Cannons, which as the name implies, fires high energy positron beams. However, in certain cases, the Yamato's guns can also fire Type 3 shells, which can be fired even with the engine off (which supplies energy for the energy beam attacks). This flexibility is a good compromise I believe.

[@hellacoorinna9995]

Yamato, Hasshin!

[@benlyon4739]

They'd need to factor in gravity as a variable when plotting firing solutions since you won't get a ballistic arc in a zero g environment

[@ElSendler]

I love the impact sounds of the shells in Yamato.

[@gegeji6442]

Loved the scene where enemies tried to attack Yamato while they where in subspace while traveling through the hyperspace gates. Due to the Law of the subspace -laser beams- energy weapons couldn't effectively be use since they just simply dissipated and forced them to charge their mega weapon the Desslar gun. Meanwhile Yamato immediately started to lob physical cannon shells back at them at full effect and managed to destroy them before they even could fully charge up.

[@nicholaswalsh4462]

As an example, I'm deeply fascinated by Steel Battleships. Yellow Sea, Tsushima, and Jutland are fascinating naval Battles and I would love to see that sort of Warfare translated into space. It wouldn't be a setting where missiles would work well. The justification could simply be that the combination of electronic warfare and point defense have made missiles impractical or something like that. Instead, Warfare is dominated by powerful batteries of kinetic energy weapons. The vibes very much work better in a soft sci-fi story where technology is closer to magic.

[@isned2000]

A something to consider, weapons that require large amounts of electricity might still have the risk for something like magazine explosions even if there are no chemical propellants or explosive shells to worry about. Capacitors and high power batteries can react violently to being damaged, catching fire, shooting jets of molten material, or just straight up exploding, and that's with relatively low power devices today. Scale that up the energy requirements of something like a laser weapon and overloaded phaser pistols acting like grenades in star trek seems pretty reasonable. This applies to other methods of energy storage too, flywheel storage systems can rip themselves into a spray of shrapnel or send heavy metal disks bouncing around if damaged the right way and superconducting loop storage can straight up vaporize itself if the cooling fails while the loop is charged up.

[@wyrmh0le]

Really good point. One thing that's still an advantage is most of those types of failures would release the energy of one shot, as opposed to a magazine explosion which can release the energy of every shot you could take, nearly at once.

[@TheAchilles26]

​@@wyrmh0le not necessarily just the energy of one shot, as you can absolutely charge up a capacitor bank for multiple shots AND the energy required to power a shot is greater than the amount of energy that shot delivers to the target, ESPECIALLY with lasers

[@mnxs]

​@@wyrmh0leIf I have a rifle-ish raingun that, say, is capable of launching hundreds to thousands of bullets per minute at sci-fi-worthy velocities, it would obviously need to have somewhere it could either store, or produce, all the requisite energy. All the energy that is in normal bullet propellants, in fact... It's a lot of juice. Take something like modern lithium batteries. They don't even come close to having the requisite energy density, and you've surely seen how volatile they can be under some (very specific) circumstances. Something that is much more powerful, well, it's not guaranteed, but it follows that there's a good chance that the handwavium can go kaboom.

[@drewrussell8531]

@@mnxs I ran into this when trying to figure out how a character's railgun pistol could work in one of my stories after I'd tweaked the setting as a whole to be more "realistic." I realized that the energy density requirements for the battery and capacitor system of a pistol-sized anti-materiel weapon would not only be well beyond the capabilities of the setting, but it would also effectively have the explosive potential of multiple hand grenades at once if it ever blew a fuse. So my character got a "normal" gun instead, which honestly felt better anyway. "Over-engineered hand-held artillery piece that only a cybernetically-enhanced individual can effectively use" ended up being way more fun to write than "handwavy sci-fi brick that makes cool noises when it shoots."

[@Zankaroo]

A more recent example of this is the Railgun in Helldivers 2. It has a safe mode and unsafe mode. In unsafe mode you can very much charge for more penetration power but charge it to long and it explodes killing you and destroying the weapon so you can't pick it back up when you respawn like other support weapons.

If we want to stick to realism, I think it all comes down to two questions: - Over what distance can laser beams be focussed effectively, without overheating? - Over what distance will kinetic projectiles be able to reach their target before they can be dodged or intercepted? (To which velocities can kinetic projectiles be accelerated?) In the void of space, range is everything and stealth is basically impossible, so whatever weapon type will have the longest reach will render the other one obsolete. I personally think lasers are more plausible, but it’s hard to say.

[@sam23696]

I agree about everything except when it comes to stealth. If you're soft sci-fi then you can have cloaking, or any kind of crazy tech, and then if you're hard sci-fi you can have conventional stealth, with a hull that absorbs as much radiation as possible with internal heatsinks. The second one works in that setting because also in hard sci-fi you'll reinforce the vastness of space, where even radar/ lidar and optical sensor systems have an unbelievable amount of vacuum to scan.

[@neooblisk0084]

I kinda disagree with the notion stealth is impossible in space, I definitly think we could see techniques used to lower the crossection, or infrared radiation or whatever of the ship. Kinda like modern stealth you don't make the plane invisible you just make it seem smaller, and even a tiny reduction in radar crossection in the vastness of space could mean a lot.

[@DecidedlyNinja]

An important note about kinetic weapons (guns, missiles, and guided shells in between) is that they become more effective in damage, range (based on difficulty to evade), and difficulty to intercept as the closure rate between the two ships increases. This means that a ship with slow weapons going up against a ship with fast weapons (especially beams) should aim to approach at the highest possible speed and will be in trouble if it fails to destroy the enemy before closest point of approach. Unfortunately, when both ships use the same weapons, neither one can gain a relative advantage this way, so it's harder to come up with interesting maneuvers.

[@griffinfaulkner3514]

This principle also makes chasing a fleeing target a riskier proposition than it might be otherwise, since the pursuing vessel would be actively accelerating into any incoming fire, increasing its effectiveness. I've been working on a setting for a while that features a trio of highly-specialized cruisers that are designed to exploit the living hell out of that principle, sacrificing effectiveness against lighter craft for the sake of having incredibly powerful reverse thrust and a fixed gravity-boosted rail cannon normally found turreted on dreadnoughts. The idea behind them was they'd be able to keep ahead of any ship in their own weight class even with the ship flying backwards to keep the main gun on target. The theory works, but the incredible cost of the ships combined with their need for a robust picket screen means the production run is limited to just three ships.

[@DecidedlyNinja]

@@griffinfaulkner3514 An even more specialized design only has powerful thrust in one direction (forward) and just has the gun mounted backwards. That has difficulty chasing down fleeing enemies, though.

[@griffinfaulkner3514]

@DecidedlyNinja The whole design was incredibly focused on shredding apart more conventional cruisers, so being able to run down fleeing enemies with extreme prejudice is extremely important. Most of the reverse thrust would be accomplished with literal thrust reversers (think Saab J-37 Viggen), so you wind up with a ship that's obscenely fast in more conventional flight regimes for its mass. For reference, the top-down profile of the ships somewhat resembles the Concorde, since shield effectiveness is directly proportional to angle of impact. The whole ship almost has a blended wing design, with the furthest outboard and rearward sections of the "wings" housing the radiator panels, and the tail protrusion housing the dampers that keep the spinal railgun from literally ripping the ship in half. The railgun itself is a whole other can of worms, but I could probably write a 60+ page design history of these things, but I digress. Suffice to say, the only conventional thing about the ships in-setting is their FTL system.

[@epicassassin8502]

@@DecidedlyNinja halo has really good examples of this with the keys loop, taking the tech advantage of shielding out of the question by ramming a ship and hiding a nuke to emp other ships, ramming is a tactic the unsc navy uses whenever possible at least in the early war because one ship of similar weight can decimate one of any tonnage where without the tactic it would take at least 3 ships of similar tonnage take out a single covenant ship while also likely losing 2-3 of the 3 ships in the process and 3-1 isn’t even a guaranteed victory it’s an even playing field

[@DecidedlyNinja]

@@epicassassin8502 I'm not talking about ramming at all (and at the speed the book implies, really both ships should have been vaporized by the collision), but I can see that battle as an example anyway. Iroquois successfully employed the slowest weapon of the engagement (a drifting nuke) by launching it at a high closure rate. However, it only worked because Iroquois was able to simply sidestep with emergency thrusters the also somewhat slow plasma torpedoes; otherwise, charging straight at them at flank speed would have been the fastest way to die. In the Nylund space battles, those emergency thrusters proved to be quite an excellent defense, somewhat undercutting the theme of human technical inferiority.

[@Gaarafan007]

Mobile Suit Gundam Iron Blooded Orphans was an interesting subversion of expectations when it came out. Energy weapons were a staple of the series up to that point, so it was a surprise that they weren't used for most of IBO's run, and one did show up, it was a big deal.

@@Tuning3434 True, but as the original series progressed, more and more units came out with beam weapons, and the main character in the show always had one.

I like how in Dune, lasguns are extremely powerful, but noone typically uses them because most things are shielded making them kind of a kamikaze weapon. Yet, for the same reason, shields are inherently risky because if someone really wanted to kill you, a lasgun would insure destruction. It also makes things interesting since shields don't work well on Arrakis, so lasguns can be used, but there's still that risk.

[@Sicarius888]

Weren't lasguns weak and ineffective in Dune and only changed to powerful in movies? I remember from books that even before shields during war with robots, ships and infantry had kinetic weapons.

I must admit that I'm a sucker for conventional kinetic and/or explosive weapons, even in science fiction. Guns, cannons, missiles, bombs, torpedoes, it's not just about the damage they deal, but the physical factors involved in using them. If you've ever seen a submarine movie where you have scenes of the crew loading torpedoes into their tubes, if you've ever seen the broadside guns in Revenge of the Sith spit out those massive shells accompanied by awesome sound effects, if you've ever played Halo 2 and heard the MAC gun on Cairo Station spooling up to fire from right below the barrel, and if you've ever seen Galactica absolutely fill the black of space with heavy cannon rounds and tracers from point-defense turrets, then you know the sheer satisfaction ballistic weapons can have in any setting. Sure, energy weapons might be more practical or effective, and definitely more creative in many examples of sci-fi franchises... but they'll never be as COOL as the good ol' gun.

[@ckl9390]

Using a laser to entertain the cats, we can see the "beam" by it partially reflecting off dust in the air. Perhaps in the given sci-fi setting, even if the laser is not visible light, what is being seen is small particles and debris intercepting the beam being superheated to plasma. Similarly, a "smoke" screen or flack cloud would act as a particle screen to disperse the beam and dissipate the laser's energy.

[@cisclanu3421]

yes but taking this into consideration, in the vacuum of space the only particles that would make the laser visible would be the parts been destroyed by the weapon, that could be launched creating a small area around the point of impact where the laser would be visible.

[@Keemperor40K]

For me it depends on the feel of the faction and what the weapon type says about said faction, add to that the effect the weapon will have and you have a lot of options to play with. Want a factions grounded in reality?, give them chemically propelled guns and leave it at that, with the occasional laser weapon (as was done with BSG and the Expanse). Want a faction to fell high tech? Give them particle/plasma/ion weapons and a sleek look. Want a faction to feel brutish? Give them large weapons, that fire obscenely large rounds for their given size and make the weapon effect feel more like an impact, than a cut. Want your faction to feel mysterious? Give them weapons that are so out of the realm of the possible that they feel like magic or that they create things that we consider impossible. Intent and effect are essential to developing the feel of the setting and the factions within. The 40K Orks would feel very different if all their weapons where shiny and efficient, similarly the Shadows wouldn't work if their weapons weren't so brutally efficient and terrifying, all of this matters when creating our sci-fi setting.

My favourite weapon mix was described in the Honorverse. Missiles with Nuke or X-ray Laser head for long range (5+ million km range); and Grazers, over powered beam weapons for short range (≤1000 km).

[@richardrothkugel8131]

I ran into this energy / kinetic weapon problem and came up with an elegant solution. In my game, weapons (armaments) are split into delivery systems, rather then damage types; projectiles (ballistic, gauss, casimir, etc., any unguided missile), beam (laser, plasma, ion, etc., a stream of energy) and munitions (mines, torpedoes, missiles etc., any guided missile or bomb). There's a good mechanical reason for this. Projectiles, based on their velocity, have drift and aren't 100% accurate. Projectile damage is relative to distance and velocity, the further away or close-in you fire, the less likely you are to hit the target, making them an ideal medium range weapon. Beams on the other hand are relatively instantaneous and are 100% accurate, however distance diffracts / reduces damage, so long range does damage, but is sub-optimal, but short range ramps damage up, making them an ideal weapon for short range combat against faster or smaller targets. Munitions are staged and guided with near 100% accuracy unless being jammed or disrupted, making them ideal for long range combat, but useless at short range combat (dead / arming zone). Being a game, players build around these limitations to maximise their ship's effectiveness while having access to many different damage types and not being restricted / shoe horned into a specific damage or weapon type.

I feel like this is the best solution. I've always thought it was silly when I saw people claim, "x is the best for space combat and makes all other weapons obsolete." They never seeem to consider the downsides of their preferred system or the advantages of the dismissed systems.

[@matt_1984_]

I mean, canonically Projectile Weapons in Mass Effect have near unlimited ammo. They have a chunk of metal, and a "shaver" to shave a few dust bits off and then uses mass effect fields to accelerate these specks so fast they hit with the same punch as a much larger projectile moving much slower. In Mass Effect 2, 3 and Andromeda, you're not replacing the ammo block, you're replacing a heat sink which allows the weapon to be fire sooner rather than having to let it cool off (like you did in 1)

[@CollinBuckman]

The pistol in the game Ultrakill works on the same principle- firing near microscopic flecks of metal at high speeds to deal large damage. It has effectively unlimited ammo, and even when it does run out it can be reloaded simply by chipping a small sliver of metal off of the gun's casing and using it as ammo.

[@DecidedlyNinja]

It never made much sense, though. A tiny metal flake of a presumably irregular shape going Mach Jesus through air without either veering off course and quickly slowing to uselessness or disintegrating and very quickly slowing to uselessness is not plausible. Maybe they could use force fields to create a tunnel of vacuum for the bullet, but that's never mentioned and would suggest that the technology exists to make holes from a distance without using projectiles at all.

[@Grimmance]

​@DecidedlyNinja the metal flashes to something like a plasma at the sped its fired at.

[@ARabidPie]

@@DecidedlyNinja As far as the irregular shape goes, I've headcanoned for a while now that the real way to do the ammo-block concept would be to have essentially a bunch of pre-formed projectiles held together with a binder rather than a solid chunk of metal. This way it's less paint chip, more tiny bullet with actual aerodynamic ballistics. This would be easier to engineer too, since you don't essentially need to micro-fabricate your ammo on demand at machine gun speeds. Instead you just need to laser off some glue. This would also make the in-universe ammo mods make a bit more sense. @Grimmance Depends on the the metal. Lead, yeah that probably vaporizes, but something like tungsten might hold up for instance.

[@Canadamus_Prime]

@@DecidedlyNinja Lest I'm mistaken, the guns use the same technology as the Mass Relays so whatever the shape of the shaving, it's being propelled at faster than the speed of light so it'll hit the target before it has the chance to veer off or slow down.

[@blademaster2390]

I’ve always been a fan of having a mix between kinetic and energy-based weaponry on sci-fi warships. Think a battleship with a primary armament of heavy railgun batteries, plus a trio of heavy energy beam cannons, plus a spinal-mounted superheavy particle lance, a secondary armament of coilguns, missile batteries, and pulse lasers, and a point-defense armament consisting of anti-missile lasers, CWIS-style chainguns, flak batteries, and some interceptor missiles. Or maybe a bomber carrying missiles or guided gravity bombs for precision targeting, and a plasma weapon for general carpet bombing. Or a fighter that uses missiles for long-range engagements, and a kind of nucleon shotgun for closer range. For ground combat, think a tank with a beam cannon and a coaxial machine gun. A soldier’s primary weapon being an automatic plasma gun, and their anti-tank weapon being a missile launcher of some kind. A sniper hitting their target from 5 or 6 kilometers away with a laser rifle. An artillery battery with kinetic howitzers and plasma mortars.

[@jakeaurod]

I think you missed something very important. "Kinetic" is often used not for the weapon but for the warhead action on target. In other words, I would consider kinetic warheads to be distinct from explosive warheads. Where you put other types of warheads, such as chemical or biological or communications, etc. Kinetic and explosive warheads can be propelled by laser ablation too, making lasers as much a propulsion system (or comms system) as a weapons system. I think a useful, if arbitrary, distinction between Directed Energy Beam weapons could be the size of the interacting element. If it's an atom, sub-atomic particle, or photon, then it's directed energy. I'd probably include Mascons in the Beam category, which I'd consider the same as or equivalent to Directed Energy. If it's a non-explosive bullet or shell, then it's kinetic. If it's a warhead that relies on some sort of internal release of energy (mechanical, chemical, nuclear, etc.), then it could be a third class. I'm not sure what is the best name for that class or category. Thoughts?

[@seanlee7558]

I feel the Stellaris way probably does the setting well. Energy is good against armour and hull. Kinetic is good against shields (and occasionally hulls). Though, reflective mirror like armour/hull and strong deflector shields might be special cases.

[@SamuraiL33]

A great argument of "it depends on the situation" is the anime Mobile Suit Gundam Iron-Blooded Orphans where beams weapons were considered relics of the past due to Nanolaminate armor which attenuates beam damage. So all weapons from ships and mobile suits in that setting use kinetic weapons

[@LatexMawashi]

One thing I've been curious about is how to handle debris and projectile pollution in space battles. As of today a few missing screws and bolts in orbit can cause some serious trouble, gatling cannons and exploding fleets I can only imagine would pose a similar, albeit scaled up, problem. It's easy enough to hand-wave in Sci-Fi as it's hard to imagine a proper space-faring civilization that hasn't passively dealt with the issue of debris and errant projectiles, but I feel like it would be a fun aspect to explore. The only setting I know of that spent considerable time on this topic was the anime Planetes. If anyone has some sci-fi recommendations on the topic of debris pollution I'd love to have them.

[@andrewreynolds912]

Using plasma to power a railgun like the expanse is pretty realistic as their are pros to it than a normal railgun

[@jonpinkston]

I think the simplest answer is that all weapons are energy weapons. All weapons take some form of energy and convert it into some kind of force. That, however, isn't really the point. The best way I would explain it is that kinetic weapons use the energy given to impart that energy as a physical force. Energy weapons take the energy with them and transfer that energy into the target.

[@hellacoorinna9995]

KEW v DEW

[@shorewall]

Even AP tank rounds today turn into a type of plasma when they hit the target, reshaping into a shaped charge that imparts the energy into the tank armor which cracks it open from the inside.

[@jonpinkston]

@shorewall That is a good point. I am not an expert on this. However, I would still say that it is a kinetic weapon. An example I can think of is getting hit in the eye. Whether it's a fist or firecracker, it still is a physical force. Whereas a laser transfers its energy.

[@jyzow]

3:39 Using CoaDE to illustrate "Lasers are longer ranged" is really funny to me, because my experience was that they were the short range option: kinetics don't suffer diffusion losses - they'll always hit with the same impact! Lasers are more accurate, which is great for point defense, but they take time to do damage so they work a lot better when fleets are in similar orbits and can sit and fire at each other. Meanwhile, kinetics benefit from getting into a retro orbit so you blast past each other at the sum of your orbital speeds, unloading your kinetics in advance (and then burning to the side to dodge!). Definitely doesn't result in the pirouettes that the Expanse has, though that may be more to do with engine tech. Hard to do those fancy maneuvers when you max out at tenths of a gravity.

[@martylawson1638]

CoaDE has some big limitations in the armor modeling. Specifically, you could only ablate a specific thickness of armor per second. So in the game optimal armor vs lasers was aerogell, while in reality aerogell would be less effective than smoke vs cutting intensity lasers. Also meant there was a hard-cap on the useful intensity of lasers. Afik it capped at 1/100'th to 1/1000'the the intensity of commercial laser cutters.

Favorite Exotic ship set of weapons systems was Macross from anime. Like most anime big ships it had a massive big gun for a main cannon that fired (in the American Version) protocolture for a common big gun but the thing that I am pointing out is the defense system was ultimately a weapon system as well. It had two modes one that was little w light squares and the other was the Barrior system. This Barrier system was maybe the biggest weapon in the series. When engaged, it could take insane amounts of damage from a fleet of targets and absorb it all BUT If it took to much it over loaded returning all of it own power and that fired into it by the enemy fleet. It blew it blows up like a bomb big enough to whip out fleets. Favorite single weapon on Andromeda was the Black hole guns - yes the bad guys shot mini black holes at targets (mind you their main ship was a mini- solar system.

With energy weapons, you also have to deal with all the excess heat. A laser powerful enough to damage and/or destroy an enemy ship 10,000 km away would require extensive heat management, such as extensive heat sinks and radiators.

[@DecidedlyNinja]

Everything has to deal with excess heat. Presently, lasers convert a larger proportion of their input energy into it than electric cannons, but future technology could change that. A really efficient laser would be scary.

[@shorewall]

@@DecidedlyNinja That's also a point I've heard for regular brass casings over plastic or caseless ammo. The brass casing acts as a heat sink that is ejected from the gun.

I would add that you could also interestingly reverse this by using a laser to "cook" a ship with worse heat management, overheating its systems and forcing its crew to surrender without having to kill them.

[@martylawson1638]

@@RorikH Yea, this is an under appreciated strategic use of lasers. It has the added benefit that you don't need a tight focus to get an effect.

In my little Sci-Fi setting, I actually have combinations of both. One side has Beam Weapons as well as preferring physical rounds, with the ammo essentially being the batteries for the Beam Weapons - detonating in an explosion of Beam energy after easily slipping past the Anti-Beam Fields... The other side has weapons that can fire a combination of physical and plasma projectiles. Designed primarily like a physical round weapon, the barrel in front of the firing chamber doubles as the plasma chamber, a barrier field protecting the firing chamber and any rounds in there. This allows for tactical flexibility on the battlefield, switching between between the 2 in a second or two. Not to mention being able to load a variety of ammo types with the physical rounds...

[@Jetfury-v2x]

Finally this is something i think about a lot

[@isaacgraff8288]

fun thought for a laser point defense system. For a laser to work you need 2 major things, an emitter and an energy sources. In theory, you do not need them next to each other. So you could have a massive energy source say, with your core engine or near it, and cables taking that energy to emitters. The defense emitters could therefore be a lot smaller and scattered all over the hull of your ship. You wouldn't have clear defense turrets shooting but an occasional unsuspecting panel on the ship shoot at a missile. This thought would work for a point defense and not for a 'main weapon'.

[@sonwig5186]

Yes this is the right way of looking at things.

[@knickohr01]

8:41 ironically, using kinetic weapons opens a slight plot hole in BSG. Even if they resupplied ammunition at Ragnar at the beginning of the series, it still bothers me that it never came up as a plot point that they should save ammo where ever possible, because they have no opportunity to restock (well, except if the Pegasus left behind most of their ammo before foolishly wasting itself). I think there is some throwaway line in the briefing before the attack on the Cylon colony, where Adama mentions throwing rocks if they run out of shells, but that is all I can remember in that regard. They wasted a bit of potential by not introducing ammo as a finite resource, which the colonials would have to manage. For example, the holy wall of flak is one of the best things to come out of BSG, but they somehow failed to consider its huge requirements for ammunition, which would be a huge downside in real life, severely limiting its effectiveness to protect the fleet in a multi-year conflict without the possibility to resupply.

They do start manufacturing their own ammunition, but it doesn’t go very well and I’m not convinced it would actually be enough.

[@copaceticetal]

In the book Mote In God's Eye the setting's force fields were so absurdly powerful that kinetic space weapons get barely a reference and most space battles become about overloading the enemy's force fields through a concentrated laser barrage. If you max out the force field's absorption rate the excess energy has to travel SOMEWHERE and cooks through the hull of the ship, causing power surges and 'burn throughs. While you don't see any happen in the story I thought was a very clever explanation/justification for the ubiquitous exploding control panels you see in most space operas.

- Kinetic weapons are non-self propelled and rely upon accelerated mass projectiles where primary damaging characteristics rely upon Newton's 3rd law. This could also include any type of shell that includes an explosive device as long as it also includes kinetic penetration as its primary function in its makeup. - Energy weapons are point to point(s) emitted energy devices, both focused and broadcast in which the primary damaging characteristics rely upon some form of radiation transfer of energy. This would include the electromagnetic spectrum, some plasma and accelerated particle weapons (as long as the particles remain recognizable as alpha, beta, gamma) While nuke warheads could fall under this definition, I would classify them as a hybrid (Explosive/thermal/energy) as typically deployed on earth. Exception would be if they are used primarily for their radiation effects only in space as part of an emitted radiation weapon. -This would mean that explosive and some thermal weapons are their own categories of weapons beyond these definitions, as well as self-propelled weapons like rockets, torpedoes, and drones.

After having played EVE, it seems more like the damage output type becomes more of a necessary point. From a base standpoint damage is damage long as there is no immunity.

So a whole big depends on the setting just like it was mentioned. That aside I love the wide variety of clips used as examples!

[@danieljackheck]

Honestly I think space combat would be a lot like submarine warfare, where sensors are usually strictly passive to prevent detection. This would give kinetic weapons, especially of the dumb gun projectile variety, a potential range advantage over something like a laser, which eventually becomes ineffective due to diffraction. If a gun fires a round a good distance away using an enemy ships known vector, what are the odds that the enemy would actually detect the projectile?

A fun thing to do can be to have different factions use different types of weapons and then use that as a starting point to build up how their ships are different. For Example: Faction A is more technologically advanced and makes extensive use of Proton Accelerator Canons. Meanwhile, the less advanced Faction B uses mostly railguns and coilguns. Because they both fight each other (because sci-fi) A optimizes their shields to counter solid objects, while B optimizes theirs to counter particle beams. As a result of this, the few old Faction A ships still in service that couldn't fit the Proton Canons for whatever reason are a huge threat to B because B's shields aren't meant to stop big lumps of metal. Adding onto that, Because B's shields are bad at stopping solid objects, they have much more extensive point defense and countermeasure systems to protect them against Missiles, while A has much lighter defenses because their shields protect them. This then leads to A making little use of offensive strike craft because B's point defenses are so thick that A's pilots have such high loss rates as to make them non-viable for offensive use, allowing them to focus on low numbers of technologically superior short-range interceptors for fleet defense to defend them against B's strike craft attempting to exploit A's poor point defenses. Eventually leading to both sides all but forgoing strike craft to focus on those big spectacle battleship battles sci-fi loves.

One problem with energy weapons is that of focusing. Any "beam" will spread over distance, the rate of spread is reduced by really good focus. So long range laser fire (in space, planetary uses don't get to this level of detail) Another problem with any direct fire weapon used in space is vibration isolation. over a couple light seconds (Earth to moon ranges) even a small vibration can throw off your aim. Assuming you have good enough fire control to hit a moving, randomly evading target at that range anyway.

@@peasant8246 Sure it does fit, Idk what you are on about. It's a weapon which can be directed and it's primary damage is caused by an energy.

Particle beam weapons in a magnetic field ( such as produced by most planets ) would be very tricky to aim, as the magnetic field would distort the beam if the particles had an electric charge and how are you going to accelerate them if they don't ? What's more, the beam bending would vary depending on the angle of the beam relative to the magnetic field, which would also vary if you were moving.

New diversionary tactic: Fire electron beams at a planet in order to create a cool Aurora Borealis (or Australis) that will cause all enemies to go outside and look, then sneak into their bases while they're taking photographs.

I think Kenetic is well kenetic energy, basically things that slam or smash something Whilst energy is thermal or electric energy, it burns or melts things. Also kinetic usually has a “round” that can be singled out as one round one shot. Whilst energy weapons are usually a fuel or power pack that each shot is part of a fuel/charge.

I always liked weapons that combine the two and fire energy-charged physical projectiles. Basically, shoot physical bullets, but surround them with an energy envelope, either plasmoid, radiation of some kind, heck even just really really hot incendiary/tracer material. The energy envelope helps with target penetration at the lower muzzle velocities, and an additional energy-based charge could be delivered on impact too. I don't know why it's not done more in sci-fi. It even accounts for most "energy weapons" shooting projectiles that move slower than the kinetic weapons!
