North Korea missiles
« on: 04/24/2016 08:34 PM »
NK missile technology is advancing across a broad front. This is the latest. Although not space-related, it shows that they're putting money into a bunch of different technologies and having some success.

Will Iran’s Simorgh Space Launcher Appear in North Korea?

http://www.nti.org/analysis/articles/will-irans-simorgh-space-launcher-appear-north-korea/

Quote
Iran has an ambitious space program. But it also has an ambitious missile program as well. Iran is now developing a larger new rocket called the Simorgh, with the goal of placing a new satellite in orbit by February 2017. Many in the United States worry that the Simorgh might also serve as the basis for an ICBM.

Concerns about Iran’s space program arise from the fact that it is largely built on technologies imported from North Korea. The collaboration between Iran and North Korea in developing rockets for civilian space launches or military missions is a subject of frequent concern in the United States. And while that collaboration has largely been seen as North Korean assistance to Iran, there are now indications that the relationship has become more collaborative over time. [1] In some instances, the flow of technology could even be shifting in the other direction, with Iran supplying North Korea with assistance. This may force us to change how we think about addressing the threat from Iran and North Korea’s missile programs.

North Korea released a propaganda film showing multiple angles of their latest submarine-launched ballistic missile test. It doesn't look like it was the healthiest rocket motor to ever fly (a significant anomaly can be seen 38 seconds into the video), but it seems to have worked.

BBC report: http://www.bbc.co.uk/news/world-asia-37670035

Not sure why there is the comment about the space programme in the above since this was clearly a missile launch and not a satellite launch attempt: for the last decade North Korea has announced its satellite launch attempts in advance and no such advance warning was given for this launch.

As the doomsday clock remains at 3 minutes to midnight, its only been closer in 1953 when the Soviets detonated a thermonuclear device within 9 months of a USA fusion test, when the clock was at 2 minutes to midnight.

How Might North Korea Test an ICBM?

http://38north.org/2017/01/jschilling011217/

Quote
In his 2017 New Year’s Address, Kim Jong Un mentioned (among many other things) that North Korea had “entered the final stage of preparation for the test launch of intercontinental ballistic missile.” It should be noted that this was neither the focus of his speech—which, for the most part, was a list of last year’s accomplishments—nor was it an announcement that a test would occur any time soon. Quite possibly, it was a signal to the new dealmaker-in-chief of the United States that North Korea might be ready to make a deal: to not conduct the provocative test for the right price. Still, we should consider the possibility that a test may occur in the near future. In which case, how might this happen and what might it mean?

Can the US Prevent North Korea from Testing an ICBM?

http://38north.org/2017/01/melleman012717/


Figure 1. The KN-14, which has only two stages, can safely be launched to various ranges without risk of the first stage striking foreign territory.


Figure 2. Launching the three-stage KN-08 to the east risks having the second stage land on Japanese territory. This would likely deter North Korea from choosing the KN-08 for its initial ICBM test launch.

On March 22, North Korea test fired another missile, which ended in failure shortly after launch.

The missile was launched near Kalma in eastern Wonsan province, where North Korea previously attempted to launch its mobile-launched Musudan intermediate-range ballistic missile.

There is not just an external audience.

The reveal of Pukguksong-1 and later Pukguksong-2 upped the ante. Solid fueled rockets always do.

One analysis says that they might be based on RT-15M 1st and second stages respectively.
Other analysis by 38north came to other, larger diameters, so RT-15M would not be a fit.

Having access to solid fueled Sowjet SLBM plans is a big deal, even if they were never fully developed.
The tracked TEL looks somewhat like the RT-15 (SS-14), biggest difference is that the original was hot launched. [link]

If Norberts size analysis checks out the chance that NK actually has something for their large ICBM canisters rises drastically. SS-13 clone anyone? - Not that they have some, that it looks like they want them to look that way...

That's a file photo of the 11 February launch of Pukguksong-2. I don't believe photos of the actual launch have been released yet. The range is given as 700 km, so this might be a Hwasong-7 launch.

Information is still sparse and subject to change but it does not look like a modified SCUD.
Roughly 700km range but highly lofted, 30 minute flight time, 2000km appogee. First analysis comes to a more conventional range of 4500km. (But beware of GIGO.)

Jeffery Lewis, @armscontrolwonk thinks that it was the KN-08 version shown in the parade. [link to video] It looks like a successfull test so we'll soon know more via NK news.

Hypergolic.  Hopefully they are designing their warheads to be able to survive a "Damascus Incident".

They are in a rush. Missing obvious steps in development. So likely they skip that too, to save time/cost.

Which is according to Jeffery Lewis one of the big problem the Chinese arms control experts have with NK.
Not so much that NK has the bomb but that they'll fsk up something. Say loosing containment of a test, again.

A much different threat perspective than in the US.

That they've studiously ignored for more than four decades ... that only they can take away. How much longer before it literally explodes in their face, when they then ... can ... no longer ... save face?  ::)

The engine used on north koreas new hwasong-12 missile is the rocket engine that will be used for their new SLV. It has been tested twice so far in september 2016 and march 2017. The exhaust from the missile is very clear and looks like the exhaust from the combustion of a N204/UDMH hypergolic propellant mixture.

It is very likely that their next generation unha rocket will have a liftoff thrust in the range of 300-400 tons and a payload of 3-5 tons LEO and 1-2 tons GTO.

North korea is clearly making rapid progress in missile/rocket/nuclear technology. I suspect that by 2020 north korea will have a level of capability that we cannot even imagine right now. South korea and japan would best boost their investment in these areas so they do not end up lagging behind north korea.

Who knows what the Chinese think?
They, and just about everyone else in the region, have thei own perspective, much different from than the others.

I'm still more concerned that a certain president decides that removing the (future) threat NK poses to his nation is worth the price the people in the region will have to pay for that. And then proceeds to find a justification to start the war. The drama has been toned down in the last days, but I'm not convinced. After all as long as the timing is right war is a tremendous way to get reelected....


For some reason I doubt that the upcoming 6th(?) nuclear test is a great reason to suddenly be all gung-ho about forcible disarmament. Not that the 7th or 8th test are a better moment.

The Hwasong 12 test and the accompanying propaganda does not help either. Most likely a single stage rocket so a lot of growth potential. By all accounts this is their own engine which removes their need to play rocket lego with knockoff engines.
Lewis thinks the emphasis on a "large and heavy" warhead in the propaganda is not so much about "Guess what, we don't need to miniaturize, we just use a bigger rocket." but rather hinting at a thermonuclear warhead.
I guess we'll find out with the next nuclear test. AFAIK most nuclear weapon states have made that step at this point in testing. - Which of course is not good news either.

China has policy about not allowing threat of any kind on its borders. Recently they've allowed critical views to be aired on the subject, where they never did before. And they have acted on that policy many times.

So already and for decades it has been against their stated interest to have North Korea act this way.

What they have lacked is the will and the initiative to remedy the policy oversight.

He's an idiot elected by idiots for the benefits of an chosen to be idiotic party, who want idiotic things done. So clearly an idiotic reaction is to be expected. This has nothing to do with China, and there are many other competing idiotic games underway aimed at others. That's unfortunately irrelevant.

Again, irrelevant. Such will find some stupid justification that the gullible will buy off on. Bread and circuses.

You look at yield, delivery system specs, and operational deployment/targets. And response to that.

You don't let irrational behavior make you irrational.

The downsides of the current nonsense in DC is that it appears to weaken the US appearance, which invites new issues as many test to see if there's really a response.

The only benefit, weak as it is, is that China has to grow a pair and see that it has far more to lose than the US does. Which, getting back to China's stated long term policy, is exactly the problem, where it's been all along.

Ironically, both China and Russia have played up against a stable US with feints. With the US possible less stable, perhaps they need to act more responsibly like "adults" instead of "kids"? Perhaps we'll see.

I sure hope our (Western) intelligence agencies do know what Chinese think.
