/k/ - Weapons

I don't mind it at all if China increases military spending to an absurd degree and starts doing WW2 Germany prototype weapon-tier projects for kicks.

Either it's bullshit propaganda they set up to start rumours, or they too are retarded and waste their time and effort on this.

>railgun shooting railway tracks

Is there a DnD spinoff with Chinese workers and railway tracks? https://1d4chan.org/wiki/Peasant_Railgun

>>547589

The USA Navy also has railguns, no big deal.

I'll be excited when they manage to make a gun out of a Plasma Focus

>a fixed coastal artillery defense for their islands than something to fit on a ship

Then could it be a conventional gun, and the containers are for power and to house the crew and comm and targeting systems? After all, it's a lot easier to move the system to its intended position if the only non-standard component is the gun itself. Maybe it's just a 130mm H/PJ38 with a funky barrel sleeve.

You mean the "we totally didn't steal anything from General Dynamics" Railgun?

>>547657

Left to right translation of captions.

Electrical fragmentation system, Transformers and circuit breakers, Operations box, Fire control Station, System radar.

I'm guessing 936 will be either based out of Hainan or Liaoning, probably Hainan. CCP had at one point outlined the need for "offensive" maritime weapons before I'm guessing this might be a unit for artillery support on coastal assaults in the SChina sea

It could totally be a 180mm (I do think china did have some) firing a saboted 100mm or 110mm guided. It would have a stupid range and a good fire rate.

>>547723

Could be. Have you hear any news of Ukranian/Polish/ former Soviet block engineers being hire en mass? Rumors in China were that they were trying to design a crusier like the Kirov but also as an agies system.

Its a shit weapon system, like lasers, except railguns are outperformed in every metric by CLGG. Its even shit for spacelaunch, since precooler SSTO can do manned launches for cheaper. Thats why anyone with any sense is abandoning railguns.

If you want to use electromagnets to throw matter, then your best bet is a particle gun of some kind. Maybe laumching atomic nuclei stripped of electrons, that would fuck someone up.

>>547708

Inb4 Yugoslavia had a military railgun in the 80s, with 7kJ power, and American railguns are partially based on it.

>nuclear water mine

go on

>>547781

I thought the only big selling factor of a railgun was safety–a few capacitors getting hit will fuck up your ship a lot less than a powder magazine getting hit.

>I have middle school science notions.

Railguns, just like lasers, are retarded passed the theoretical field because with the amount of energy you need to actually launch a kinetic projectile at the same distance and do the same damage upon arrival as a random 155mm HE would is ridiculous.

If you're gonna use that much energy, there are ways to discharge it that would have a much better "generator to bang" efficiency.

The US navy railguns, are gigantic (internal space) with a usable range as a weapon between a 76mm and a 155mm (without RAP).

>But but but muh BAE range.

In test they have only succeed in 10MJ, because the capacitors to fire it at the power required to toss the thing out at 32MJ simply don't exist.

And at 10 MJ you still need 25 Megawatt to run it for a muzzle velocity of around 1300 ft/s of muzzle velocity, out of an 18 inch gun firing a full metal 23 lb projectile...

A Mk 45 (5 inch) gun reduced velocity comes out at 1,500 ft/s with a 70lb round... of HE

An 18 inch gun (40 cm/45 Type 94 Japanese... AKA the biggest gun ever fitted on a battleship) fire a 3 200lb shell at 2,420 ft/s.

Do I have to explain to you that if I put the powder charge of an 18inch conventional shell that is 140 times heavier and is coming out at twice the speed, under the 23lb 18inch railgun shell, you can probably land it on the moon?

>>547754

Sure.

>>548864

So what is better:

Railgun 1 kilo slug moving at mach 7

10x cheaper, simpler and more compact CLGG doing the same

Particle gun moving 1 gram of ionized gas at 0.98c?

Thats even ignoring the fact that there literally is no way to armor against some particle beams… electron beams can quantum tunnel through armor, muon beams collapse the armor into micro black holes that instantly explode….

>>548930

I think mystery-anon was saying that the CLGG was an order of magnitude better than railmemes, not worse.

>>548933

I know, all I want to say that they are even better than that.

>>548935

>>548930

tl;dr i was lowballing it for simplicity

in terms of energy delivered nothing beats a particle cannon

>>549901

Made a thread for it. >>549903

>>549906

Hmm? Math?

23lb= 10.43kg

I'm assuming when they speak in MegaJoule it's of kinetic energy out of the muzzle (and not the energy they put in the thing).

Kinetic energy law K=1/2mv².

64000000 = (10.43/2) x v²

v²= 32000000/5.22

v²= 6130268.2

v=√6130268.2

v= 3501.5 m/s

3501.5 m/s = 11487.86ft/s

So the 23lb 18inch shell need to fly out of the gun at 11,487.86ft/s to get 64MJ of muzzle energy.

That looks amazing right? Let's do the old jap conventional 18inch gun...

3,200lbs = 1,451.5kg

2,420 ft/s = 737.62 m/s

K= (1451.5/2)x 737.62²

K= 725.75 x 544083.26

K= 394868425.95

So... it's a 395 MegaJoules gun. So yeah, we know how to make guns that do discharge way way way way more energy.

Let's do the Mk 45 (127mm) regular naval shell.

2,500 ft/s = 762.0 m/s

70.0 lb = 31.75 kg

It's 9.22 MJ.

As for sauce, pick any really here from this summer

https://insidedefense.com/insider/electromagnetic-railgun-will-demo-10-rounds-minute

>Within the year, Thomas Beutner, Naval Air Warfare and Weapons department head at the Office of Naval Research, told reporters July 20, a 32 megajoules electromagnetic railgun will be demonstrated at Naval Surface Warfare Center Dalhgren, VA, using a new composite launcher firing at 10 rounds per minute.

(They didn't)

>The service will also conduct the first-ever hypervelocity projectile flight demonstration in 2019, Beutner said.

Now what is hypervelocity?

Well you go grab your AR 310-25 for the pentagon approved definition:

>Hypervelocity:

>1. Muzzle velocity of an artillery projectile of 3,500 feet per second or more.

>2. Muzzle velocity of a small arms projectile of 5,000 feet per second or more.

>3. Muzzle velocities of tank cannon projectiles in excess of 3,350 feet per second.

3,499ft/s = 1066m/s

1066.8²x5.22 = 5931778.32

So almost 6MJ.

10MJ which is the thing that comes back in most sources about successful testing, with a 23lbs shell is 4540.68ft/s. And 10MJ is only gonna get as hard hitting as a MK45 (well no, because the M45 is full of a high explosive and not just metal).

Which is nothing to brag home about out of an 18inch gun, to give you an idea the basic OTO Melara that on nearly every ship in the world 3inch gun is a 14lb shell at 3000ft/s and 120 rounds per minutes in it's newest edition... (instead of 2 so far, 10 planned).

Also the shells are clearly some type of sabot... meaning I have no fucking clue if the projectile is actually 23lb or if it's the whole thing.
