If you're interested in this story, it may be in print somewhere, but
it's also in this podcast that you can listen to online, with no

Hint: They didn't do it themselves.



It is very easy to make a rocket. The difficult part is the flight
control unit that keeps the rocket flying straight and narrow instead of
going in random directions after liftoff and crashing back to earth near
the launchpad.

A modern smartphone has all the sensors required to let the rocket
correct its course and guide itself to its destination.

All you need to do is write an App and send the output to an interface
to control the power of each of the three nozzles (a rocket as no wings
or rudder, so a minimum of three nozzles would be needed to make the
rocket go in any direction you want it to).

North Korea makes smartphones:

Download this Android App (Sensors Multitool) to read the sensors:

This "Sensors Multitool" App can read all the sensors in your Android
smartphone (everything you need to guide a missile to its destination):

The story is about the engines. N. Korea couldn't get a mid-range
rocket to fire reliably. All of a sudden, they're building ICBMs that
work.

The analysts recently realized why. The engines are Cold-War-Era
Russian -- possibly made in the old Russian heavy-engine factory in
the Ukraine.

I think you mean mean russia, not ukraine.

The factory is a holdover from the Sobiet days. It's in Ukraine.

there is no ukraine, just russia.

We must have different world maps.


But they say they're not making engines for N. Korea. The CIA probably
knows the answer to this, but it could be that Russian engineers or
unemployed Ukranians are helping N.Korea to build them.

The key point was in realizing what was new about their program. In
roughly one year, they made progress that is widely thought to have
been impossible, or nearly so.

Launching a rocket into the ocean isn't really that impressive, unless
you're trying to catch up with the 1960s.

Launching one to an altitude of 2,300 miles is very impressive. Angle
the trajectory down, and most US cities are in range.

Did you follow the analyses of the launch data? The rocket experts say
the last one is a game changer.


North korea is a joke, but at least they'd put up a fight if the russians
walked over and said "this is ours now."

Security experts are focused on other issues regarding North Korea.


Kim Jong-Un doesn't need to buy old rockets from Ukraine. Rocket engine
schematic diagrams are readily available on the internet.

RS-25 schematic:
https://en.wikipedia.org/wiki/Space_Shuttle_main_engine#/media/File:Ssme_schematic_(updated).svg

As I said before, you need at least three nozzles so that you can make
the rocket go whatever direction you want it to go (by adjusting the
power of each individual nozzle):
https://en.wikipedia.org/wiki/Space_Shuttle_main_engine#/media/File:020408_STS110_Atlantis_launch.jpg

North Korea's Kim Jong-Un and his rocket scientists had the smarts to
assemble their own rocket engine from Home Depot parts, and use the
sensors in a smartphone for the guidance system.

You seem to have a cartoonish view of engineering, a lot like the
cartoon drawing you linked to above.

The most fundamental problem with your "analysis" is that they DIDN'T
have the smarts to build even reliable shorter-range rockets, until,
quite suddenly, they had success with much larger and longer-range
rockets. Intelligence services were scratching their heads.

But Kim Jong Un's egotism led him to have photos of the new engines
published, and US intelligence analysts

The problem you have is your blind trust in your "US intelligence
analysts".

I don't have a problem, but you do, trying to explain why N. Korea
couldn't build a reliable mid-range rocket, and now, suddenly, they're
building successful ICBMs.

Explain that one with your paranoid fantasies.



They switched from 'Bing' to 'Google' and found the right schematic'.

They are the same clowns who didn't know the 9/11
perpetrators were hatching their plan for 10 years right inside the US,
and who said Saddam Hussein had WMD (which was proven didn't exist).
They are famous for writing their reports by making **** up while on the
loo.


quickly realized they're now
using Russian-designed engines from the Cold War era. Those engines
were originally made in the Ukraine.

You would know all of this if you listened to the podcast instead of
speculating about cartoon drawings and Home Depot.


Now I'm sure you're pulling our legs. No one is that stupid.

It corresponds to their getting their hands on Russian rocket engines.



Why buy when you can make your own? I have already shown you how easy it
is to make a rocket.

No, you showed us a cartoon drawing that you probably don't
understand.

That is not a 'cartoon drawing'. That is a schematic diagram of a V2
Rocket (the very first viable rocket made by Hitler's rocket
scientists). All the US rockets were based on that after the US captured
and shanghaied Hitler's rocket scientists; either bring the rocket
technology to work for Uncle Sam or face the Nuremberg Trial:

schematic ~ adj
1. represented in simplified or symbolic form

Is this a slip of the tongue? Or perhaps you just don't understand
complex matters? Have to rely on a simplified drawing?

While it may come as a surprise, some here can actually "read" a
print. Why not something a bit more detailed, say

Strange though, the three exhaust nozzles that you keep mentioning
seem strangely absent.
