& # 39; It’s very, very big & # 39 ;: the experts analyze the new images of the sophisticated missile of North Korea


North Korea launched a series of photos on Thursday, showing the record intercontinental ballistic missile the isolated nation launched a day earlier.

The missile experts were impressed. "This is the biggest advance in a year of great developments," said Jeffrey Lewis, an badyst at the Middlebury Institute of International Studies.

This photo was taken on November 29, 2017 and published on November 30, 2017 by North Korea The Central News Agency of North Korea (KCNA) shows the launch of the Hwasong-15 missile that is able to reach to all parts of the United States.

Here's why:

& # 39; It's very, very big & # 39;

The missile, called the Hwasong-15, is the largest so far, which explains it's far-reaching, Lewis said. The first stage seems to have two large engines, capable of about 80 to 100 tons of thrust, Lewis said. The Hwasong-15 tested on Wednesday reached an altitude of 2,780 miles, the highest so far. It would have had a range of 8,100 miles if it had flown on a flat trajectory, according to David Wright, an expert with the Union of Concerned Scientists. That would make it able to get to Washington, DC

Cone of brutted nose

The top level is also great, allowing North Koreans to choose between equipping it with a larger thermonuclear bomb, lures that could help avoid defense against the US interceptors. or multiple warheads, said Lewis. It has a cone of nose blunter, that could help to restrain the warhead and make a smoother transition towards the terrestrial atmosphere.

Reentry has been a challenge for missile designers in North Korea. "The nose cone seems to have returned to a previous design," said David Albright, president of the Institute of Science and International Security. But that design could also slow down the missile and make it more vulnerable to being intercepted, he said.

Improved steering

The first-stage thrusters appear to be capable of turning, allowing the missile to be directed more efficiently. The most primitive rocket designs use fins for steering, which can cause drag and reduce speed and range. "It's a new and elegant trick that we have not seen before," Lewis said.

Truck manufactured in North Korea?

The launcher was mounted on a truck larger than the previous missiles. Perhaps even more alarming is that the truck was built by a factory in North Korea, since the photos published on Thursday were taken in an automotive factory. Most of the previous launch vehicles were Chinese made. "They can build as many as they need," Lewis said, without having to depend on the Chinese. Mobile launchers are important because they can make it harder for the United States to detect a launch before it happens. On the contrary, fixed sites can be viewed continuously. "They wanted to show they could attack without warning," Albright said.
