Cuz who doesn’t like electromagnetic projectile launchers?

Sound is bizarrely missing for large portions of the video for me.

thats an awful lot of explosion for an electromagentically launched round.
Very cool looking slow speed stuff though.
If you’re referring to the fireball in the first shot, a lot of material gets vaporized during the process, and I’m sure the electricity arcing between the projectile and the rail is a big contributor.
The first projectile has a funky shape because of the way it’s launched - it actually conducts electricity through itself, so has large “pads” to move as many electrons at once as it can. The later projectiles are probably packaged in a sabot to maintain the aerodynamics of the ejected projectile.
In that video I saw SABOT and SABOT with grape shot. I wonder it it’s possible to do HEAT / HE warhead. And actual accuracy, continued fire round/frame of time and heat generation…
Like how they figured the height the projectile would fly so it would stay in the middle the entire length of the billboard they used to calculate its speed.

Ah! The next A-10 upgrade.
How far are these projectiles going? I mean, for battle.
All the way to impact.
The predicted effective ranges for these weapons is on the order of 220 to 260 miles.
Wow, those distances definitely changes the effective offshore firing range of any ship.

Unless that thing has terminal guidance mechanism and you can see that far out to shoot and correct it, those numbers are meaningless. IMHO
I was wondering the same thing - trajectory dispersion due to normal atmospheric variation/winds/etc. would make a mess of the endgame at those ranges, but the articles I can find are pretty silent on the terminal phase. I’d expect some sort of terminal guidance is required to be effective, and it’s not like we already have some experience with guided artillery rounds.
Exactly. Lob a piece of metal at those distances and KE value will be null if it manages to hit. Also not sure SABOT is the most effective weapon of choice vs other ships. I’m guessing it’s just for demo purposes.
So the question - can an industry create senors (battery, guidance etc) that will survive acceleration. I don’t do math, but public source says its velocity is somewhere of 2.5Km/second. So we have barrel length, start state (zero velocity) and end state.
So it will take about 2.3 seconds to go 220 miles…
Let’s say the target is a ship 110 miles out. 1-1000, that’s fast.
Oh no, it’s about 70 seconds… for 110 miles
errr…2.5km/s = you travel 2.5km in a second. so that’s - 2 seconds you travel 5km.
I was trying to fix it before anyone replied
lol.
So to continue my rambling. Normal artillery shell exit velocity is around 500-700m/s and it can guide excaliber guided munition. 2,500 / 500 … so required durability of 5 fold.
Interestingly enough this little guy does 1,600 m/s only slightly less than 100 years old.
I can’t believe this bothered me so much…sorry for spamming. I can do basic math. Assume 10 meter barrel. 0 to 2,500m/s. Assume it takes .004 seconds to reach that speed/distance…625,000G.
Anyhow. Google has answers. USA Electromagnetic Rail Gun Proposal - NavWeaps
Hey,
I could really REALLY need your help.
Would you like to code for a game? Small work, I’d do the most- I was actually in need for a ballistic simulation.
Would you like to discuss about it?
Hell yeah!
