Posted on CDF a while ago, don't think it was cross posted over here. Don't think we have a rail gun thread so may as we'll include it with lasers.

Simulation of a 200mm rail gun. If they're considering a rail gun of such calibre you'd think they must have done some smaller scale practical rigs too.

The English abstract speaks for itself.

I posted this earlier in July in the General Chinese Military and Defense (sp) thread.

Found here at this blog.

Rick Fisher thinks it's legitimate enough (though the blog seems rather general in tone, spends a lot of time talking about foreign technology).

I must confess that that report is a lot more speculative on the subject of Chinese railguns than I remembered it (having read it 3 years ago).

Edit: the blog says that China tested a railgun in August 2006 that fired a 25 kg shell over 250km in Inner Mongolia, and work is being done on a railgun with 50kg shells*.

The Beijing Nonferrous Metal Research Institute and Harbin Institute of Technology are apparently leading Chinese researchers into railgun technology (the blog post also notes that Chinese literature onto railgun research is relatively open, compared to the US (their words, not mine. Should be an interesting endeavor to dig into Chinese scientific abstracts on the subject one day)). Apparently one Richard Marshall spoke at a Dalian university and got to see one of their coilguns.

Again, credit to Fisher for finding that blog post.

*I highly doubt that China has a remotely practical railgun. A railgun is straightforward enough to build. But building a railgun capable of multiple firings is another matter entirely (not much use in mounting a one shot railgun turret on a 055 CG, I'd say), so the U.S. is most likely ahead in fielding an operational railgun.

Edit: Appears to be this Richard Marshall, an Australian who was on the US National Advisory Panel on EML Tech. Interesting. Had a lab in Beijing too (though obviously of civilian purpose).

Recent Xinhua news revealed a portable laser air-defense system for low-flying, small, and slow air targets. It was designed to secure large venues from unauthorized drones, as AA missiles or guns will be too loud and too dangerous to use near crowds.

It was claimed to have shot down fixed wing, helicopter, and multicoptor drones in 30+ trials with 100% success rate. They said its output level is around 10kw and can intercept flying objects within 2km radius in under 5 seconds. They're also said to be developing similar devices with higher power and longer range.

Not to mention totally unsuitable, as I don't think AA guns can effectively track such small, lower flying targets as commercial drones, never mind be able to effectively engage them. Police would probably have a far better chance of shooting such things down with their sidearms.

But this is a very interesting technology development that fills a new niche. I can see it being popular if ever offered up for export.

Before the above was developed they have already fielded special "missiles" equipped with low noise propellant and a 3m^2 net warhead to capture low-flying drones. They started using it to secure large events as early as 2010. This is what it looks like:

I wonder if any other country has developed anything similar for this purpose. It is quite easy and relatively affordable nowadays to get commercial drones which you can not only remote-control, but also pre-program to fly to a location a few kilometers away with a few Kgs of payload. It's only a matter of time that some people take advantage of this for malicious purposes. There is certainly a need for anti-drone security equipments around the world.

Interesting. Looks like China might have beaten Israel's Iron Beam to the punch (though the later might be planned to have a more powerful laser).

True but missiles still creates back blast from the engines that has fire potential hazards in a tight urban environment.

Yeah but those commercial drones are easily susceptible to small EMP weapons or electronic jamming devices that can take away it's power and control. Although I do agreed with you that some terrorists are probably studying this option.

That is very interesting, its always a treat to learn about something new you never knew about, and I thank you for letting me know about the Chinese 'skynet' (that's what the direct translation of the name of the missile would be).

If I was in charge of Chinese state security, I would have been sorely tempted to leak just the name and the fact that the 'system' was nearing operational use just to mess with western intelligence analysists. :D

But on a more serious note, I think the commerical drone industry really needs to be reigned in for security and privacy concerns, because the potential for misuse is far too great with the current limitless free-for-all.

A drone with even a few KG of HE can cause enormous damage since the drone can circumvent most conventional security measures and so could delivery its payload to where it would do the most damage.

Imagine someone flying a drone packed with HE into a sports stadium, or landing it on top of an oil/LNG silo or a packed commerical air liner on the ground at an airport...

But even those horrific scenarios pale in comparison to the nightmare scenario or terrorists attacking a radiological device onto a drone an detonating it high above a major population centre.

Even if the device doesn't go full critical and produce a nuclear explosion, the fallout from the dirty bomb would be dispersed exponentially wider than even a far larger dirty bomb going off at ground level.

The target is literally burned out of the sky by the laser. I suppose the 5 secs involve the targeting and the time it takes to burn the target. Could a more powerful laser, like 100kw, cause the target to explode in a direct hit?
