"Star Wars wouldn't be the same without the screams of TIE fighter engines or the flashes of brightly colored lasers crisscrossing space battles, but we know that no real space battle would go down the same way. Sound gives outer space character, in Star Wars--and in most science fiction--but real space battles would be soundless and a whole lot less flashy. In fact, they'd probably look nothing like the battles of Star Wars or Star Trek, which are filled with futuristic (but hardly realistic) technology…."

There were some holes in that article that made me flinch. For example, to get a 10kton ship up to a yield of 84.5 gigatons requires hitting 69.5 percent of light speed. That just doesn't happen in hard science fiction since you never have that much fuel unless you have a magi-tech drive. (I have a RKV calculator here if you want to play with the numbers,

Space combat would be far from soundless, but it would be a different set of sounds. The whine of servos and capacitors, the crack of (chemical) laser systems igniting, the mechanical undocking or launching of missiles, the noises all ships and stations make. The sounds of threat indicators, damage control alarms, explosions due to enemy action, and phalanx defense systems and counter measures going off. All that will carry though the hull even if the air has been pumped out to reduce decompression effects and stop fires.

I once heard a pretty good description of a space battle.

Go into a large, fully darkened building at night, you and your buddies are equipped with a stethoscope and a bazooka, go hunt your buddies …

The description of an interstellar conflict :

"The war began with the customary barrage of a quadrillion smart relativistic kill projectiles towards the planet."

A starship capable of traveling between stars with any amount of self-respecting firepower would hose down a planet with a capacity equal to a gatling gun shooting nukes. Once you reach a certain point there are no "unarmed ships"

I'd honestly expect the tactical computer to add surround-sound effects inside the bridge or inside the various crew's helmets, just to help with situational awareness of what is out there.

And you don't need gigaton kinetic impactors, 'mere' megatons will work. The Barringer Meteor Crater in Arizona was a ~3.5 megaton kinetic strike. The 10kton freighter would need to be going all of ~387kps for that, if I've done the math correctly. And that's a totally achievable speed in a continuous-burn drive, something getting 0.1m/s/s will be four times that fast when it hits Earth after failing to turn-over on the trip from Mars. 1342kps at impact.

Even if it just failed to burn after turnover and kept on closing at it's midpoint speed, it'd be traveling at 670kps, enough for a gigaton impact. Scale of damage from something like that? 2004 Indian Ocean tsunami.

But what would it sound like?

Ahhh, zircher; I missed that the first time through…

A much better site with more thorough analysis of space warfare

I too have a rocket simulator you can download.
It uses anti-matter as fuel but it heats an inert material to eject for propellant.
Basically, this is 90% of it's initial mass.

Now, with the SF writers discover that a suicide ship moving at very high speed can destroy anything else they have to come up with ways to stop this. Like only humans can navigate hyper-space so no AI pilot such ramming ships.
Here is a video on TIE fighter battles.

This author discovery of kinetic energy is usually a failure to do the math of their rocket design. A failure to figure out how much fuel/reaction mass/power they need to use to get the acceleration they're describing.

Like I said, you don't really need much acceleration at all to be trundling around the solar system in reasonable travel times. Well, weeks to go someplace, so think train travel across Europe or ocean liners.

Thanks for the links….

I believe that when space combat becomes common there will be in interstellar treaty requiring that a 'sound effects radio frequency' be established and every ship must broadcast 'pew-pew!' noises when their weapons fire.

Conflict in space will be conducted by AI or remotely piloted drones. The craft will look like little blocky suitcases with weapons pods and communications arrays, and an occasional solar collector deployed. Not a hint of streamlining or similarity to manned aircraft. There will be nary a sentient biological participant.

Legion 410 Jun 2019 7:29 a.m. PST

Well if I'm ever involved in one … I'll let you all know !

Aethelflaeda was framed In the TMP Dawghouse10 Jun 2019 7:34 a.m. PST

Legion, I think infantrymen will have no chance of that, the sentient part at least, now for artillerymen that might be another story….

Legion 412 Jun 2019 6:39 a.m. PST

frown Well we might be needed for boarding actions … evil grin

Lion in the Stars12 Jun 2019 1:57 p.m. PST

Yeah, I wouldn't want to be involved in a boarding action.

Read this little blurb for reasons why: link

Legion 413 Jun 2019 12:49 p.m. PST

I probably wouldn't either ! evil grin Like having a firefight on the Moon or any place with no atmosphere !

Lion in the Stars, I liked that article. I was thinking about boarding actions in the winter trying to come up with reasonable scenarios for them. Agreed that going through the airlock would be a bad choice as you're heading into a prepped kill zone. My thought was small craft carrying maybe a platoon that could land/latch on where it wanted and then blowing/cutting a way in to avoid the traps. My main question was what kind of cutter/weaponry could a small craft carry that would be able to quickly get through armour plating designed stop capital ship weapons? Any ideas people?

Mobius Supporting Member of TMP14 Jun 2019 11:51 a.m. PST

@Zinkala, you'd probably have to wait for the plating of the heavy ships to be breached before trying to board through the openings. Ships with powerful lasers must have heat radiators and cutting through them then into the ship may be a weak spot.
