China Ballistic Missiles and Nuclear Arms Thread

[AndrewS]

Thaad at S Korea , and possibly later at Philippines and Taiwan means China land based nuke counter strike will become useless. It's next gen 096 and submarine based JL3 ICBM will become critical.

That's not the case. Chinese IRBMs targeting WestPac locations will be far cheaper and more prevalent than ABM missiles.

For intercontinental targets, the most sensible trajectories go over Russia. Again, ICBMs are far cheaper and more prevalent than ABM.

The most sensible trajectories (for American targets) may well go over Russia but the ascent phases for many missiles will begin in Manchuria, which will possibly become vulnerable to THAAD, which apparently does have ascent phase capabilities in addition to being a terminal phase interceptor.

If I was a strategic planner, it would be better for SSBNs to have longer ranged missiles rather than having to breakout into the Pacific. But better yet, land-based missiles would probably be more survivable.

There are too many chokepoints with too many sensors already eg. SOSUS/Seaweb

I do wonder what China has developed already, as this stuff is in the public domain.

I'm a little perplexed about ascent phase interception, it seems like the target rocket has a great deal more advantages in that its path of ascent is near vertical where the interceptor needs to travel to the same altitude at a slant angle traversing potentially a great distance inland during which it itself is vulnerable to interception... is it really very realistic?

 

[Insignius]

THAAD deployment in South Korea just means that South Korea will be nuked by IRBMs shortly before ICBMs are sent against the US.

Not very clever of the South Koreans. But if they want to commit joint-suicide with their master across the pond, so be it! Their loyalty to the death is to be commended, in any case.

THAAD

Range: 200KM
Altitude: 150KM

There's no way a Korean THAAD intercepter can reach a ICBM missiles travelling from Manchuria to North America.

I think it's the radar range that can track it in the early stage to give it an early warning system.

Yes, it seems you are right. I haven't looked at a map of the Korean peninsula for a while and my impression of it was that it was far smaller than it actually is.

if this is "China Ballistic Missiles and Nuclear Arms Thread" why you guys discuss Korea?

you'd better pay attention to the new developments in SRF, p.e. discuss new missile base in Henan, just complete...

Wu14 and DF ZF:
The problem is cooling the warhead
You can use ablative materials or, for mach 20, air film cooling

The paper says:

Objective To put forward a new approach of active thermal protection system termed as film cooling for future hypersonic vehicles (Mach 20 flow) and validate its performance by CFD. Methods By solving Reynolds-averaged Navier–Stokes equations, the finite-rate chemical reaction model with Park-I 5 components (N2, O2, N, O, NO) 17 equations was used to investigate the real gas effect. For the typical blunt body, a numerical study of the effectiveness of film cooling was presented for Mach 20 flow at 30 km, with the special designed micro inject hole located at the stagnation point. Results The reduction of heat flux on the isothermal wall (300 K) with film cooling at the vicinity of the hole could be as much as 90% compared to that without film cooling, and the covering area of the coolant flow could be 10 times larger than the out area of the hole. Conclusion The study showed promising prospect of film cooling for heat proof of future hypersonic vehicles.
