How N. Korea suddenly had ICBMs that work

Your ignorance is showing. You do not know your guidance from your flight controls.

This appears to be a Space Shuttle (STS) main engine, a VERY sophisticated piece of turbomachinery. I seriously doubt the North Koreans could make one of these work in less than a decade. It stretched the capabilites of the US to make them work, and were a continuing source of problems throughout the program.

Wrong attribution, Jon. That was our Home Depot aerospace engineer. I'm doing my best to hold in the laughter. d8-)

Well, if the guidance system fails catastrophically, it can lead to the missile breaking up from dynamic forces. If it fails less badly, the range safety officer will have to blow it up before it hits a populated area. Most tests have command destruct systems. No idea if they do that in DPRK, though.

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

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 has 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:

It is such a simple construction, please explain to me which part you or Kim Jong Un cannot make (if you have the money and tools).

Not really. On the Trident Missile General Electric makes guidance units. Lockheed makes flight controls.

As I have explained before, all the sensors required to control a rocket

are inside a modern smartphone. Please let me repeat my post:

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.

Anyway, a modern smartphone can achieve both tasks because it has all the sensors required. Please let me repeat my post:

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

North Korea's quantum leap in missile technology coincides with their foray into smartphone manufacture:

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.

Their rocket fuel is from electrolysis of water (hydrogen and oxygen).

Their flight control sensors are from smartphone parts.

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

And you've shown us that you're a simple-minded troll.

Enjoy your psychosis.

there is no ukraine. there is only russia.

yes, very impressive, if you're in the 1960s.

"the rocket experts". LOL

More experts? better grab some paper and a pen to take notes.

None of those 5 rocket failures crashed into a city. Only china could pull off that trick.

The point I was trying to make is that North Korea's success in new missiles (not blowing up off the launch pad) has nothing to do with Clinton giving them the 'guidance system'.

Nobody needs Clinton's 'guidance system'. All the sensors required for flight control and guidance system are inside modern smartphones (and China makes almost all the smartphones in the world).
