KINETICS IN SCI-FI | Why do guns keep showing up in science fiction?

[@tomc.5704]

Gunnery Chief: This, recruits, is a 20-kilo ferrous slug. Feel the weight. Every five seconds, the main gun of an Everest-class dreadnought accelerates one to 1.3 percent of light speed. It impacts with the force of a 38-kiloton bomb. That is three times the yield of the city-buster dropped on Hiroshima back on Earth. That means Sir Isaac Newton is the deadliest son-of-a-b*tch in space. Now! Serviceman Burnside! What is Newton's First Law? Serviceman Burnside: Sir! An object in motion stays in motion, sir! Gunnery Chief: No credit for partial answers, maggot! Serviceman Burnside: Sir! Unless acted on by an outside force, sir! Gunnery Chief: Damn straight! I dare to assume you ignorant jackasses know that space is empty. Once you fire this hunk of metal, it keeps going till it hits something. That can be a ship, or the planet behind that ship. It might go off into deep space and hit somebody else in ten thousand years. If you pull the trigger on this, you are ruining someone's day, somewhere and sometime. That is why you check your damn targets! That is why you wait for the computer to give you a damn firing solution! That is why, Serviceman Chung, we do not "eyeball it!" This is a weapon of mass destruction. You are not a cowboy shooting from the hip! Serviceman Chung: Sir, yes sir!

Neat trivia - Gunny is within an order of magnitude, if not closer on the amount of energy carried by a 20 kilo slug doing 0.013C. Impact energy will depend on how much of that energy is dumped into the target, how quickly. (anything from a hole the diameter of the slug straight through from one end to the other, on up to a 6 mile diameter crater that doesn't quite penetrate the 7 mile thick armor)

I think with kinetic weapons it's also often a matter of aesthetics and how "realistic" they want things to come across. Reboot Galactica and The Expanse were definitely going for a much more grounded grim and gritty mood than something like Star Wars or Star Trek, and part of that was using more "realistic" weapons than bright colorful lasers beams. I also really liked how Halo used the UNSC relying or kinetic weapons while the Covenant used energy weapons, to highlight how the Covenant had more advanced technology.

[@jacobnebel7282]

Kinetic weapons are absolutely terrifying if allowed to benefit from the same technological advancement that makes DEWs viable in a setting. Not only do kinetic weapons do significantly more damage for a given amount of energy than lasers, they also have this interesting property where their wattage on target increases the quicker defenses try to stop it. UNSC technology was inferior to the covenant's, but that has nothing to do with kinetic weapons. If UNSC small arms used MAC technology, ground battles would have been a slaughter. A tungsten toothpick doing even mach 20 is going to do terrible things to whoever it hits.

A practical reason for not using high energy weapons in space scifi is heat management (which is frequently neglected). Getting rid of heat in a vaccume is difficult and flying around mid combat with huge radiators deployed sound like a good way to break them. Lower energy requirements -> less heat generated -> better combat stamina before cooking your crew alive.

[@certhass]

well, to some extent that also applys also for kinetic weapons. the need for cooling the barrels is ignored almost 100% but there are some sci-fi books which at least adress the issue of radiating heat of the ships. just recently read one where ships had to drop out of a battle and deploy radiators. if they dont, the crew gets cooked...

[@Ser-Vex131]

I always thought a cool idea for space heat dissipation would be to have a backup stock of a liquid compound that has a ridiculously high boiling point and temperature transfer. You fire until the liquid hits a pre-specified heat and then vacuum it into space and turn it into a heat ghost in space. Or store it so deep in a vacuum container the middle of the ship until the end of combat that a scanner couldn't just read the heat. (Of course this may not be great in an extended battle)

Gunpowder does have oxidizer, so does nitrocellulose (smokeless powder) and so does cordite, all common gun propellants have included oxidizers, because in the chamber and barrel of a gun the access to atmospheric oxygen is practically none, especially with the very short combustion times available.

[@rhodes3983]

The Expanse solves the recoil proble really well. If you look closely at the martian PDCs you can see a small rocket engine firing out of the back of them. They have a built in recoil compensation rocket engine. And with the railguns they are usually mounted on warships massive enough to not be affected by the recoil or they are built in a way so that the ship's main engine automatically fires every time the railgun is used.

[@onerxowns2202]

I was thinking about SPG-9 style recoilless guns but belt fed, i mean ignition problem (see RPG-7 firing pin placement and method of actuation), we could use electric spark instead. This way we have guns that have no positive or negative recoil and thus did not disturb space ship movement pattern. Actually in space we could make recoilless guns of practically any size if there be no atmosphere (cause that would be dangerous).

[@Beuwen_The_Dragon]

It is likely not a rocket per se, but redirected gasses from the fired cartridges. It would reduce the overall velocity of the fired munitions slightly, but it would reduce a percentage of the total force of recoil.

[@weasel003gaming7]

There's also the factors of recoilless rifles which we still use in modern day, like onerxowns2202 talked a bit on. So long as you design it recoilless, a weapon can technically be as powerful as you wish it to. Just be sure of the backblast, of course.

The meta angle on including kinetic weapons in military sci-fi (of varying hardness) is a fascinating one. A standard slug or an HE shell is understandable for the general audience, one thing punches a hole in thing, and the other explodes in its face with sharpel. But then you can really scratch the proverbial technobabble itch with various colorful and cool descriptions. A guided HEAT shell, a gigantic uranium spike, the holy canister of flak. It kind of manages to satisfy both the casual part of the audience and the hardcore military science enjoyers. To various degrees depending on execution but still. And yes, guns are simply cool as hell.

[@Myuutsuu85]

It is relatively easy to shield something against heat. Laser weapons are nothing but heat. Shielding something against kinetic energy is actually quite harder.

[@mage3690]

Yeah, clouds already attenuate lasers to the point that most wavelengths longer than X-ray are nearly useless at any range longer than a CWIS shot. Imagine what would happen in space if a military ship started dumping literal tons of shredded aluminum foil into the battlespace.

The Expanse's guns don't push their ships back because the gun turrets themselves have thrusters behind them to compensate for the recoil (the thrusters ignite whenever the guns shoots). Battlestar Galactica guns may have a system to compensate recoil too.

Energy weapons should have heat or power draw limitations, but most settings with that sort of stuff assume some kind of limitless energy and then handwave the heat.

[@FearlessSon]

A note on the railgun versus coilguns: railguns are certainly physically simpler than coilguns and easier to engineer, but they're not necessarily easier to maintain. The rails need a gap between them to fit the projectile, and the narrower the gap the easier it is to fire. It needs to do that because the projectile is a point in the circuit and the electricity needs to arc between it and the rails. This arc though can create problems with ablating the surface of the rails every time it fires. After a few shots it begins to degrade. So something using a railgun is going to need to replace the rails between battles, and probably will need a machine-shop to smooth the rails again after they've been used. It might also involve secondary systems on the railgun itself. For example, railguns in The Expanse mitigate the wear by pre-cooling the rails with chilled hydrogen gas vented over them. This gas also becomes the medium the electrical arc goes through, so they can have a wider barrel gap. This also produces the visual effect of the gas glowing purple from the arc and getting blown away when it fires because it too had become charged. (which also just looks really cool on camera.)

[@grimm516]

[@GoranXII]

Guns are simple, both to understand, and to engineer. They can also be much more robust, have a _theoretically_ unlimited range (the round will travel until it hits something, which energy weapons will lose energy or cohesion with distance), and depending on size can be loaded with a variety of rounds. It's also imaginable to have different types of projectiles on the same vessel, big coil/rail-guns for anti-ship work, and chemical-projectiles for point-defence work.

[@duckpotat9818]

[@Tourniquet]

A note on flexibility with kinetics; in universe they are also flexible due to being able to be loaded with different kinds of ammunition (HE, incendiary, various sub-munitions, hollow point rail gun slugs like the Autumn in Halo, etc.). There's also the brutality implied in kinetics (something lent into by the original 40k designers), a laser or other energy weapon will burn a little hole or disintegrate a target and is very clean, a kinetic will punch a giant hole doing insane damage to the target if it didn't paint the room with their insides.

[@mage3690]

Actually, pulsed lasers can basically deliver an explosive right to the skin of a target. They're experimenting with that for non-lethal use and secondary effects on target, because explosions on a hard surface have a nasty habit of propagating through the material and creating shrapnel on the inside, a la the HESH round in common British use. Additionally, you could use an AESA as a weapon by focusing the effects on a particular area, flash-boiling the water _inside_ a target. From the outside, it would look like nothing, and then the guy just explodes into steaming chunky salsa. No crack-bang, no nothing other than maybe a mild sunburn, just BOOM, cooked Jerry nuggets.

[@larsmurdochkalsta8808]

@@groomschild1617 TLDR: I agree with the broad strokes I just think APFSDS is a better comparison than HEAT a whipple shield or spaced armor which would be the nearest ground vehicle equivalent work for very different reasons. But I definitely get what you're saying. Spaced armor works against heat because the plasma jet from a heat warhead can only remain cohesive for a certain distance, and you're just keeping that distance further away from important stuff. Whereas a whipple shield relies on that projectile fracturing you mentioned. By shattering the projectile and scattering it in a bunch of different directions making it so each piece doesn't actually have enough energy or mass to penetrate. But APFSDS doesn't just instantly break up on impact, It is essentially erodes itself and the armor simultaneously. The rate at which either one is eroded is based on the relative density of the materials. But this only applies for relatively homogeneous armor. If there's a big enough gap in spaced armor It can actually work like a whipple shield causing the projectile to deflect witch changes the impact angle. Which could do anything from shatter the projectile to just increase the apparent angle of the armor by forcing the projectile to hit it at an angle. My understanding of rail guns is they're going to behave like something between modern sabot and very heavy space debris. Which is handy cuz they both do damage in a similar way. Which is essentially the projectile and or the armor shattering inside of the vehicle. Shooting spall everywhere.

[@adamrak7560]

that only works if laser weapons are very rare, otherwise every warship would have special sensors for detecting lasers and dielectric mirror cover to reflect 99.9% of the energy. And other countermeasures, like ejecting lots of small thin plastic dielectric mirrors (glitter). Covering the warship with a mirror layer would work better than throwing out glitter. Below the mirrors could be a thin ablative layer to delay the overheating somewhat by boiling away (and the gases also catch some of the laser too). These mirrors weight almost nothing, but would wear out under harsh conditions, so that layer would need regular maintenance. If mass allows it, the ships could have an emergency phase change cooler, the simplest is just water, but there may be better choices. Also if the range allows it moving randomly can help to avoid being focused on. That only works with long range like 300 000 km, but it would be interesting to calculate what is the closest range where the random movement avoids most of the laser energy, but the acceleration does not kill the occupants.

Capital Naval Autocannons in Battletech use a plasma explosion to fire the projectile several kilometers at the target. At least in game there is a reason to have them since they can to critical damage through armor, just like ACs on tanks and Battlemechs, since lasers are mostly used to melt away armor. And the larger the cannon, the greater the damage but the shorter the range, just like regular ACs. For example, the Naval AC 10 (10 Capital Damage, 100 Standard) has a maximum range of 44 hex, which are 792 Km (one hex on a space map is 18 Km if I remember correctly), the NAC40 (40 capital damage, 400m standard) only got 24 hexes, but can almost one shot any smaller ship. Or to just to bomb a city from orbit if you don't want to deal with it and save the nukes for later. The ballistic weapon with the most range is the Light Naval Gauss Rifle, with a max range of 56 hexes, or 1008 Km. That is the same range at which railguns in The Expanse are used in CQB.

I would just like to note that while your ranges for the hex grid are indeed correct, the in universe weapons ranges would not be the same.

It isn't more about how far a round can go but it's operational range. If you're too far or the round is too slow, it can be detected and intercepted by point defense or evaded.

Kinetically hitting something with a lotta speed shall never come out of fashion

[@animeyhem9780]

Simple...because they work. Rail guns, slug throwers, flechette guns, shard shotguns, flak guns, they all have real world analogues that we all can understand. Also, projectile weapons require less power than energy weapons, and are more ruggedly designed and less likely to malfunction than those delicate high energy components that compose energy weapons. And there's something just so satisfying making something go "bang" and then seeing holes appear in whatever you're shooting at.

[@joshuaturner4602]

Its important to note, that as kinetic weapons approach a reasonable fraction of the speed of light they approach atomic weapons in destructive yeild. if about 1% of the mass of a hydrogen bomb is converted into energy (probably an overestimation) we get m/100*c^2, A kinetic weapon fired at 1% the speed of light has a yieled equal to m/20000 *C^2 (1/200th), but that gap lessons significantly as you account for relativistic effects and simply make the slug bigger. As for the flexibility of railguns, you can definately use single slugs, canister/grape shot turns it into a relativistic shot gun, and once you deal with the effects of being really fast I think you can get significantly more creative. In a TTRPG I am running where railguns are the standard weapon there is a railgun round that functions like a shape charge, where upon impact is fires a lance of liquid lead to burn through armor plating before the remains of the round fragment after it giving it significantly more through armor effectiveness.

[@doomspud6302]

The main thing I love about kinetic weapons is the potential for variety. When you get into the details, there are a TON of different kinds of munitions you can be throwing around. That's something most energy weapons don't have, unless you get so specific that only a particle physicist will understand the differences. In general, laser acts like a laser, whether its 40 megawatts or 400 terawatts. But with bullets and shells, you have SO MANY OPTIONS. Is it a kinetic penetrator? Does it fragment? Is it incendiary? Does it explode? What kind of warhead does it carry? Is it guided? How is it fired? Is it a chemical explosive? Is it magnetic? Is it rocket propelled? Is it accelerated by an artificial gravity well? Does it create an artificial gravity well when it impacts the target? I always like it when a universe makes ballistic weapons really common, coming in all shapes and sizes. And there are a few exotic energy weapons that are extra special. The game Brigador does this really well. Many of the guns in it are actually the future evolution of WWII weapons, like the Browning M2, and MG-42. But then you have some more exotic stuff, like a gamma ray emitter, sonic cannons, and a static discharge gun. And of course, some giant lasers and railguns to really make a mess of things.

[@mage3690]

Actually no, there are lasers that deliver differing effects on target that have nothing really to do with wavelength. Pulse the laser rapidly, and the laser doesn't heat as much, and you get a nice explosive effect as the laser burns off the surface material of whatever you're shooting at, then turns that little cloud into plasma. Continuous, focused use has a penetrative effect. Unfocused, it's a dazzler or heating weapon. Use a weaponized AESA to create a relatively short-ranged but much more powerful lance that you can point anywhere at will, solid-state. If you can use wavelengths that penetrate a target, that AESA could also focus its effects _inside_ the target, blowing it up from the inside out. As a bonus, an AESA also has built-in redundancy, but makes for a much larger target. If you have truly colossal amounts of power and enough precision, focusing enough lasers on one spot will create a tiny, temporary black hole, allowing you to bend a shot around a chaff screen, or redirect an enemy shot to somewhere it wasn't aimed, up to and included right back where it came from. NASA has already created a tractor beam using lasers, use that to push the chaff out of the way, or catch incoming projectiles. And I'm sure that I haven't even begin to imagine all the possibilities, just like I'm sure no one imagined all the things that projectiles would become back when the cannon was a thing only carted around by horses.

[@professorkatze1123]

Boom boom guns are usually cooler than the pew pew guns

[@Tounushi]

In my personal 'verse, infantry firearms are jacketed in an alloy that allows projectiles to go through low-level personal shields. The problem is that the jacket ablates and you're left with the core of the projectile, so you're hitting your shielded target with unjacketed bullets. An enemy faction fires pellet hyperbursts: super-hardened pellet followed by an unjacketed pellet, with a superheated or supercooled pellet as the third projectile.

[@warhiever1803]

For me, Kinetic weapons go further since the projectile is solid. Lasers are like flashlights, further out more spread. Plasma is a excited ball of energy giving off its energy throughout flight. All 3 can exist because they do different roles for damage. But good old mechanical firearm functions regardless, plus dakka

[@tarektechmarine8209]

Range will also be a factor. Plasma and lasers lose energy over distance, so that may also be another use for them, even just more penetrating power, get through stuff instead of needing to melt the entire armor section. Cost can also be a factor on larger systems where you need to use a ships power source in order to use an energy weapon.

[@sanguinetales]

Lasers have the lowest range dropoff because they're light. They can hit the furthest fastest.

[@HappyBeezerStudios]

In principle the maximum range of a kinetic projectile itself is infinite. But usually at some point it either hits something or gets moved off course by gravitational pull.

[@ProfessorRadio]

Something interesting for coil or rail guns, which also apply to normal guns but a bit more fiddly is the payload of the projectiles, or more specifically the speed is variable which is great if you want to launch a small probe to peak around that planet

[@HappyBeezerStudios]

Oh good point, the railgun can not only yeet out the brick of death, but also do low power science stuff or medium power missile launches.

[@Stormkryptonian]

​@@HappyBeezerStudiosthe scary thing is rail and coil guns can yeet out any payload as long as it's properly containerized. So you can have a rail gun yeeting out nuclear fusion explosive rounds if they were built to withstand the G force GREATLY enhancing the efficacy and destructive power of the weapon system. In the homegrown sci Fi stories I make up, larger higher end warships are absolutely terrifying because they can rapidly ripple shoot multiple of those rounds at planets completely undetected because unless you specifically saw the ship fire you'd never know the rounds were coming. Excellent deterrents

[@nagyandras8857]

Now now , you see a space ship , you know its speed and heading. You got your battery of firearms. You know how long it takes for the projectiles to get there. So , given you know how fast can the given ship change direction and velocity , you can safely calculate every possible space the ship will be present when the projectiles get there. This calculation is done on earth too. Anti aircraft defenses relayd on this. So its absolutely feasable in space too.

[@Wastelandman7000]

This is correct. Unless the ship can teleport or similar fuckery.

[@nagyandras8857]

@@Wastelandman7000 maybe teleporting has some limits too , and thst can be factored in. Now shooting to all these locations with energy based or beam weapons or whatever .. would be extremely expensive. Missles torpedos etc are the same. And still , its in space so nothing stopping missed rounds etc till they eventually hit something. It was a problem for anti aircraft battery too on earth. Shells not hitting an aircraft did fall back down. Even if they exploded prior. From that altitude even a small fragment was a hazard. So over civilians/sensitive places it was not wise to fire em . For that reason plain old bullets kinda make a lot sense in space combat. Has to be small enough so stray projectiles don't make a mess later... and they have a very small radar / heat signature. I see plenty of reasons to have space weaponry very simular to anti aircraft battery. Many many "turrets" that can be synchronised by a ballistic computer. Given the extreme ranges thats the only likely workable thing. A guided missle of some sorths sounds nice , but it be a Hell lot of expensive , and frankly does not offers the advantage of a swarm of bullets.. limited fuel , with the ranges we talk about means , the missle would eighter be very big (easy target for a gun to hit) or would loose fuel to manuver. Then its Just.. floating away with its momentum. And way more dangerous when it finally hits something , somewhere. As.. it will. But none knows when , where, or what.

[@TarsonTalon]

The way I see ballistics vs. energy technology is this: Ballistics are more deadly, but energy weapons have better logistics. At least, that's how it would be in my world building. Your point defense weapons would likely be lasers, but your mid ranger weapons would be ballistics, and your long range weapons would be missiles.

[@Mand.alor-the-Rebel]

[@richardkenan2891]

Realistic ranges for space combat make energy weapon combat much more practical. Ships that can and do travel between stars won't be restricted to ranges that would make a tank commander flinch. They won't even be restricted to ranges that would make sea-navies think "Hmm, not much has changed." When ranges are measured in light-seconds (at least) instead of meters or kilometers, aiming with lasers seems much harder - and aiming with kinetic energy weapons seems downright impossible.

[@hammer1349]

​@richardkenan2891 tbf there is realistic range for energy weapons and then realistic range for kinetic weapons. For the most part it comes down to the power of the energy weapon and the targeting capability of the kinetic one. Energy weapons have a limited range by nature where as kinetic ones trade their range advantage for speed disadvantage. Laser weapons would be faster than plasma but also potentially substantially weaker as they required prolonged contact with the target for maximum damage. I find Halo does some of this the best as most weapons systems on UNSC ships, most definitely the MAC weapon is controlled by a miniature super computer which is able to do the calculations necessary to get an accurate enough shot.

My first Windows computer came with a Mech game called G-Nome. I was so taken by it I wrote a sci fi novel based on the game. I even acted out the battle scenes on the game. I went into detail on the advantages and disadvantages between energy weapons and missile / projectile weapons. a) Logistics: Missiles and projectile weapons require a supply chain where energy weapons only require a power supply, albeit a large power supply but if one has power for propulsion, one has power for weapons. b) Effectiveness: Missiles & projectiles are less effective against energy shields while energy weapons are less effective against armor. So the tactic would be to wear down the energy shields using energy weapons and then pound the armor using missiles and projectiles.

If memory serves in The Expanse, their point defense gatling guns got this kinda mini rocket thing at the roughly back middle of the barrels, firing in tandem with the barrels to compensate for recoil.

If the setting is anywhere close to realistic, projectiles are always going to be one of the cheapest and efficient ways to transfer destructive energy into the target. They work for the same reason wheels and levers will still be around: physics and math.

[@Wastelandman7000]

Because they work. And they don't need a science degree to do maintenance. And also, once the projectile is launched it doesn't need expensive guidance systems, and they don't diffuse at distance like lasers, dissipate like charged particles or plasma.. A projectile will still have its same kinetic energy as it did when it left the muzzle. Unless its aimed at a planet in which case it will be going even faster because of gravity.

[@Ashanlor]

One factor that I think makes ballistics still common is the energy density is high compared to mass. While can be heavy, the trade off is you take a stable explosive powder and slug that is able to transfer a lot of energy into a target. One thing we're seeing with things such as lasers is that they are not the scalpel that some settings show them as. They are hot, but they need to stay on target for long periods of time to heat up the surface. This requires a lot of control and a lot of energy needed to power the laser. For a bullet, just ignite the powder and make sure it is going in the right direction.

[@ashleylentz2651]

A question like this and trying to weigh in like "guns are so slow, everyone would move their ship away from them", kinda suggests a hollywood understanding of how guns work. When gunpowder detonates, it turns into gas and expands. It feels instant to us, but in reality, it is a process that takes an amount of time. The more gunpowder, the more gasses are expanding and the longer they continue to expand, until the bullet leaves the barrel. (Therefore longer barrels do impart more energy to the bullet, if there's enough gunpowder to keep pushing until the end of the barrel.) So really, you could make a bullet fly as fast as you want by just putting more gunpowder behind it. Magnum rounds are literally the same sized round, but in a longer case, with more gunpowder behind it. So for example, a .22lr might fly 500 to 1000-ish fps depending on the load and barrel length, and a .22 magnum could fly 1200 to 2000-ish fps also depending on load and barrel length. The only limitation really is: how strong the bullet is, how strong the chamber is, and how strong and long the barrel is. If you want to fire heavier slugs, or just fire the same slug faster, you just build a thicker chamber and a thicker and longer barrel and put a ton of explosives behind the bullet.

Firearms are simple machines with long life spans with proper maintenance. To make a laser, particle, or plasma weapon the size of a rifle or pistol. You have to overcome engineering and power source problems. The weapons have to be light enough to carry by an unaugmented human or alien species. Yet have enough punch to kill. Sometimes through body armor. Gun powder, brass or steel casings, and a bullet in the proper proportions can kill a bull elephant with 1 or more shots. Yet still be carried, aimed, and fired by a normal, average human male. The rifle will kick like a mule but it gets the job done in relatively small package. Now imagine a 1918 BAR chambered in .458 Winchester Magnum. Sounds crazy but some guy chambered a M1 Garand in .458 WinMag. Unless you got some incredible body armor or an energy shield that can stop Kinetic Energy projectiles. You're dead if that hits you, even if it's a arm or leg shot. Economy of energy and engineering is why Kinetic weapons will still be around in the far flung future. We still use knives. Just made with carbon steel instead of flint rock. In a SciFi setting you can limit their effectiveness by ammunition and range. Or limit their use to criminals, private citizens, or partisans. As the military personnel are armed with advance direct energy weapons. That can be mass produced.

By the way, modern propellants contain their oxidizer so you wouldn't need to change that, current guns literally work in space. Easiest way to understand this is the fact that the compellent is never exposed to air in typical operation. Because if you have big enough gaps that the propellant gets exposed to atmosphere then instead of deflagrating the charge detonates, which basically means that instead of pushing the bullet it cracks the chamber or the bolt and you know, explodes in your face. Kentucky ballistics style, Though what happened there was due to undercompressed powder which is probably kind of the same thing on a technicality but not really.

Umm, you forgot the Gyrojet guns. The projectile is fired first under very low muzzle velocity, usually just enough to spit it out the equally very short barrel at which point the bullet turns its self into a missle or rocket and accellerates itself resulting in zero recoil to what ever fired it. Bolters in WH40K and Smartguns in Cyberpunk. So you have a weapon somwhere between a missile and a gun, the simple function and use of a gun of just point and pul trigger and the target lock and follow ability of a missile.

Really great video. Small correction: Unitary explosives, both high-order (TNT, RDX, etc) and low-order (gunpowders of various kinds) usually have their own oxidizer built-in. That is usually denoted by the "-nitrate" or "-nitro-" component of the name. For instance, in blackpowder, the oxidizer is the saltpeter, aka potassium nitrate. Small opinion: Energy weapons disperse. Beams of laser light (for instance) disperse just as beams of regular light do, only much, much more slowly. The further away from the weapon you are, the less concentrated the weapon's beam is. A gigantic chunk of metal traveling at [get fucked] *%* of the speed of light **does not** disperse. You could be on the other side of the solar system, and if it hits you, you get **the full** package of energy the launching weapon gave it (minus whatever energy was scraped off by the fifty three hydrogen atoms between the point of launch and point of impact, but that affects beam weapons, too). I grant this is likely to be relevant only in edge cases, but it is nevertheless worth thinking about.
