China's best pupil to reenact the DF-5 ICBM first ever full range test flight

[Galactic Penguin SST]

China's best pupil, namely North Korea to reenact the nuclear deterrent DF-5 ICBM first ever full range test flight

The need for China to raise all doubt in the West about the credibility of its nuclear deterrent has pushed Mao back in 1972 to perform a full test flight of its ICBM. Due to numerous delays and political changes, the flight test of the DF-5 would be demonstrated only 8 years later on May 18th, 1980, in the Pacific Ocean, and not in the Indian Ocean as originally planned.

This year of Fire Rooster will see a North Korean demonstration of its capability, necessitated by the West's scepticism. The missile will only be a modest Hwasong-12 IRBM with a maximum range of ~6,500 km. But the quadruple multiple launches will increase the difficulty level of the operation! The highly lofted trajectory is meant to escape all conventional kinetic interceptions, such as Patriots, SM-3, and THAAD... As a Mach 25 speed reentry will render an interception unlikely.

Reasons illustrating the North Korean decision:

Is Russia Sightless or Is It Mimicking Blind

Ri Chol Ho, a researcher of the Institute for International Studies of the DPRK, on August 9 issued the following article, titled, "Is Russia Sightless or Is It Mimicking Blind":

The news of the successful launch of inter-continental ballistic rockets of the DPRK, which put the whole land of the US, the empire of evil, within its striking range, has been afloat all over the world as breaking news.

The US, an aggression state which has brandished a nuclear stick of aggression and oppression century after century, has finally been dumbfounded in the face of the Juche weapon, and the whole world is now turning its eyes to Songun Korea with admiration.

The international community was unanimous in commenting in high terms that the fact that the DPRK's ICBM reached the maximum height of more than 3 700 km and flew nearly 1 000 km and that the launch was made at high angle launch system more rigorous than actual maximum range flight conditions is demonstrative of the substantial might which is capable of putting even the eastern areas of the US, including New York, to say nothing of the western areas of the US, within the firing range.

The DPRK's ICBM, a noble fruition of its great policy of simultaneously developing the economic construction and the buildup of nuclear force, is clearly recorded in space as a pronoun of defence of international justice and peace, both in name and reality.

But only Russia is making a far-fetched assertion, denying this stark fact unanimously acknowledged by the world community, while feigning blind and deaf.

Russia, a country bordering the Korean peninsula, is calling the DPRK's ICBM a medium-range ballistic rocket with 681 km of height and 732 km of distance. This is utterly ironical.

The US, situated in the American continent across the ocean, dares not deny the fact even though it is reluctant more than others to acknowledge the DPRK's success in the ICBM launch. A big question is how come the ICBM of the DPRK is taken as a medium-range ballistic rocket by Russia, a country very close to the DPRK.

Another question is that Russia, which will be grouchy if it is ranked second in military standings, is making desperate efforts to make its far-fetched assertions sound plausible while misusing even the name of the Defence Ministry.

The world people are watching the erratic act of Russia with surprise as its authorities and the public have differing stand over the launch. Lots of military experts, media and social circles of Russia are unanimously acknowledging it as ICBM launch, but this is denied only by the authorities.

What is skeptical is that whether Russia's virtual concept on object is not ruled by its perversity and jealousy that a big country's rifle should be regarded as a rocket and a small country's rocket should be taken as a rifle.

For years, Russia took outwardly strong stand toward the US, as it used to say that "sanctions resolutions" against the DPRK should not affect the normal economic and trade activities of the DPRK and its people's living at a time when the issue was on agenda at the UN even though Russia was subject to trouble as a key target of sanctions and pressure by the US. Therefore, the world has been skeptical about its assertion of calling the ICBM a medium-range ballistic rocket. However, Russia, which had showed bravery as if it was going to hinder the adoption of the "resolution sanctions" against the DPRK, boarded the ship operated by the US all of a sudden to be "complimented" by Trump. This is quite enough for the world to guess what was the true aim sought by Russia in insisting that the ICBM of the DPRK was a medium-range ballistic rocket.

The far-fetched assertion of Russia has become an engine that heartened the DPRK to work for more launches of ICBM and compelled it to take new measures for action.

It will be clear to Russia itself whether it is really the blind or is feigning the blind.

If Russia does not drop its own "big power concept" which it values so much, the reality in which it is not treated as a big power even though it is a big power will be its permanent destiny.

KPA Will Take Practical Action

General Kim Rak Gyom, commander of the Strategic Force of the Korean People's Army, released the following statement on August 9:

As already clarified, the Strategic Force of the KPA is seriously examining a plan for an enveloping strike at Guam through simultaneous fire of four Hwasong-12 intermediate-range strategic ballistic rockets in order to interdict the enemy forces on major military bases on Guam and to signal a crucial warning to the US.

On August 8, the KPA Strategic Force through a statement of its spokesman fully warned the US against its all-round sanctions on the DPRK and moves of maximizing military threats to it. But the US President at a golf links let out again a load of nonsense about "fire and fury," failing to grasp the on-going grave situation. This is extremely getting on the nerves of the infuriated Hwasong artillerymen of the KPA.

It seems that he has not yet understood the statement.

Sound dialogue is not possible with such a guy bereft of reason, and only absolute force can work on him. This is the judgment made by the service personnel of the KPA Strategic Force.

The military action the KPA is about to take will be an effective remedy for restraining the frantic moves of the US in the southern part of the Korean peninsula and its vicinity.

The Hwasong artillerymen of the KPA Strategic Force are replete with a strong determination to fully demonstrate once again the invincible might of the force, which has developed into a reliable nuclear force of the Workers' Party of Korea and the world's strongest strike service, through the planned enveloping strike targeting the US imperialist bases of aggression.

The Strategic Force is also considering a plan for opening to the public the historic enveloping fire at Guam, a practical action targeting the US bases of aggression.

This unprecedented step is to give stronger confidence in certain victory and courage to the Korean people and help them witness the wretched plight of the US imperialists.

The Hwasong-12 rockets to be launched by the KPA will cross the sky above Shimane, Hiroshima and Kochi prefectures of Japan. They will fly 3 356.7 km for 1 065 seconds and hit the waters 30 to 40 km away from Guam.

The KPA Strategic Force will finally complete the plan until mid-August and report it to the Commander-in-chief of the DPRK Nuclear Force and wait for his order.

We keep closely watching the speech and behaviour of the US.

The role of Space Tracking Ships

2009-10-26

In 1965, Premier Zhou Enlai first proposed the concept of China developing its own ocean-going space tracking ships. In July 1967, the Chinese leadership approved a large-scale shipbuilding project known as Project 718 to support China's first full-range ICBM test flight from Shuangchengzi missile test site in Northwest China to the target zone in the South Pacific. The project included two 21,000t missile and spaceraft tracking ships (Yuanwang 1 and 2), an ocean scientific survey ship (Xiangyanghong 10), and an ocean rescue ship (Dajiang class), all to be constructed by Jianan Shipyard in Shanghai.

The first missile and space tracking ship Yuanwang 1 was launched on 31 August 1977, followed by the second ship on 1 September 1978. In early 1980, a large naval task force consisting 20 surface ships departed from Shanghai to the South Pacific for the scheduled missile test. On 18 May 1980, a Dongfeng-5 ICBM was launched from Shuangchengzi and the warhead was successfully recovered by the naval task force waiting in the target zone in the South Pacific.

In the mid-1980s, Yuanwang 1 and 2 were also involved in the full-range test flight of the Julang-1 submarine-launched ballistic missile (SLBM) and the tracking of China's first geostationary orbit communications satellite DFH-2 and the third-stage of its Changzheng-3 launch vehicle. In 1986, the two ships received their first modernisation refit to support China's commercial launch services for international customers. In the late 1990s, Yuanwang 1 and 2 received their second major refit to support the flight missions of China's Shenzhou manned spacecraft.

Since North Korea is not known to have developed ocean scientific survey ship for mapping the gravity field and magnetic field of the Guam region, they must have used other means to acquire these critical data.

·To support North Korea's first full-range ICBM test program (Project XXX): Gravity and magnetic survey for missile ballistic correction

Gravity field information of the American continent must be collected as it plays a critical role in any future ballistic re-entry of nuclear warhead, and because it is kept for this same reason as a state secret by all nations.
Whithout gravity field data, it is not possible to hit targets. During WWII, the Nazi Germans failed in their attempt to strike London with their newly developed Aggregat SRBM, because they were unable to obtain gravity field data of London.

The North Korean satellite navigation system

2017/07/24

The North Korean missile launch control station receives radio signal from radars on board Kwangmyongsong-3 and Kwangmyongsong-4, respectively, and sends them to inflight missiles. The missiles receive the radio signal and updates their flight directions in real time. The satellite navigation system will be in operation. This satellite navigation system is linked to the satellite navigation system installed on the North Korean IRBM/ICBM, medium range ballistic missile, and submarine launch ballistic missile. It is only natural that the ballistic missiles equipped with such satellite navigation devices have precision strike capabilities.

North Korean scramjet engine

2017/07/17

If North Korea had made a Hwasong-14 ICBM with triconic nuclear warhead, it would not claim the missile as a "new strategic weapon that the world does not have and can not imitate."
As you can see, the idea is that the Hwasong-14 ICBM is a completely new missile with no equivalent in the world and that can not be imitated.
Like the Russian Topol-M ICBM nosecone, the long, thick conical-shaped Hwasong-14 warhead nosecone is an indication that the nosecone contains a scramjet-powered warhead that alters course midflight.

The "plan for opening to the public the historic enveloping fire at Guam" should means live broadcasting of the operation.
From the process of moving, fueling, erecting, launching, and in flight [rocket cams] ballistic missiles, starting from showing four Hwasong-12 IRBM TEL exiting an underground base in an unknown location in the middle of the night. And it could show the scene where the Hwasong-12 IRBM warhead reentry vehicles shot by unmanned reconnaissance drones and the like hit the sea target at the end.

In order to succeed, North Korea is likely to fire at [several thousands of km perigee altitude highly lofted flight path] way over the 150 km and 500 km or even more, to overcome the SM-3 and THAAD interceptors.
North Korea's missiles are said to be able to strike targets in a way that they can go up vertically and move horizontally, then vertically down from the target. This is the information that was conveyed directly to the main office by the representative of the National Communications Agency of the DPRK.
The frequent high-angle launch drills in North Korea is meant for the training of such missile strikes. In the recent high-altitude firing method launched by North Korea, if the horizontal range is increased, then the missile would be able to hit anywhere in Guam, Hawaii, and the US mainland.

If North Korea succeeds in the enveloping fire at Guam in this way, it will deal a major blow to the US military's credibility.

North Korea's influence on China and Russia will grow even more, and it will become more difficult for the United States to pressure China and Russia over North Korea.

So there is no reason for North Korea to hesitate to demonstrate its enveloping fire at Guam.

KPA Strategic Force Command Inspected

[2017-08-15]

Kim Jong Un, Chairman of the Workers' Party of Korea, Chairman of the State Affairs Commission of the DPRK and Supreme Commander of the Korean People's Army, inspected the Command of the KPA Strategic Force on August 14.

Then, at the command post, he listened to General Kim Rak Gyom's decision on the Strategic Force's plan for an enveloping fire at Guam.

He examined the plan for a long time and discussed it with the commanding officers in real earnest.

He praised the KPA Strategic Force for drawing up a close and careful plan as planned and intended by the Party and examined the firing preparations for power demonstration.

After listening to the commander of the Strategic Force that it is waiting for the order of the Party Central Committee after rounding off the preparations for the enveloping fire at Guam, he said with great satisfaction that the spirit of Hwasong artillerymen is very high and he was freshly determined, seeing by himself the combat preparedness and the sky-high spirit of the Hwasong artillerymen of the large combined unit.

North Korea's ballistic missile strategy has been revealed for the first time officially.

At the headquarter of the North Korean Strategic Command Force, three maps are hanging on the wall behind the chairman of the Workers Party of Korea (WPK), Kim Jong Un.

These maps are clearly marked with the words South Korean Operation Area, Japanese Operations Area, and US Pacific Operation Area.


The text has not been deciphered by processing.


Inside the Strategic Command Post, there is also satellite imagery that is supposed to be the Anderson Air Force Base in Guam on the Pacific.

It shows the Anderson Air Force Base, with B-1B Lancer, B-52 bomber, etc.

On the map of 'Strategic battle plan' placed in front of Kim Jong Un, there is a long line from North Korea to Guam. It indicates the flight path of the ballistc missile.
The launching location, is situated in the area of North Hamgyong province.

What is unusual is the presence of an unknown mark at middle of the path from North Korea to Guam.

It shows that there will be some monitoring in the Pacific Ocean at that location.

It is possible to measure the distance, speed, angle and altitude of the ballistic missile from an observation ship in the Pacific Ocean mid-point from the North Korean launch site to Guam.

It is estimated that if the missile can hit its target off Guam, then that space tracking command and monitoring ship will order the rentry vehicle to self-destruct, to avoid capture an analysis by the enemy.

In addition, through the official media, North Korea has released photos of for the first time, including the strategic command post, headquarters and underground bunkers.

The center of the Strategic Force is the missile guidance station.

Pyongyang Beer Festival 2017 - Cancelled

23 Jul 2017

By Koryo Tours

Sadly today we have been informed that the 2017 Pyongyang Beer Festival has been cancelled.
The 2nd Taedonggang Beer Festival was due to take place throughout the month of August and following from the huge success of last year's festival would have been one of the highlights of the year.

As well as the opportunity to try some of the DPRK brews, the main reason for attending this festival for tourists is the excellent mingling and interaction opportunities with the hundreds of local people who attend every evening.

The reason for the cancellation is unclear and we don't expect full information to be forthcoming

The fest was supposed to be held from Victory Day (July 27th) until the end of August at an excursion ship and the wharf along the Taedong River running through Pyongyang.

Economic motivations for conducting the test

This will be a demonstration of the North Korean defence industry. A success will certainly boost North Korean missile exports.

Especially in countries in the Middle East that are the biggest weapons buyers.

On July 21, the Free Asia News Agency reported that the United Arab Emirates (UAE), a major US arms importer, purchased US $ 100 million worth of North Korean weapons by 2015, violating sanctions against North Korea.

According to NKNews on February 10, North Korean mission to Tripoli, Libya, on Feb. 8, reported that they discussed all aspects of military cooperation at the Defense Ministry and Defense Ministry headquarter. The Libyan government, a pro-American regime, has left the reconstruction itself to North Korean companies.

If the "Guam enveloping fire" operation succeeds, the exports will increase.

Iran, which is emerging as a military country in the Middle East, will further strengthen its relations with North Korea, and Saudi Arabia will strive to establish relations with the DPRK.

African oil rich nations and resource rich nations in Southeast Asia will all seek North Korean help.

These resource-rich countries have frequent disputes with neighboring countries and need a strong army to defend their resources.

Therefore, it seems that there is no reason to hesitate from the position of the DPRK for the Guam enveloping fire operation.

The best time to do that will be when the annual joint US-South Korea military drills, named Ulchi-Freedom Guardian, slated for Aug. 21-31, has reached its peak.

Unless the United States cancels the drills, which is unlikely.
