Iran Press/ Asia: The first- and second-stage engines were tested Saturday and Tuesday to evaluate the technical specifications of the newly developed high-thrust solid-fuel IRBM engines, the Korean Central News Agency (KCNA) said.
"The first ground jet tests of the first- and second-stage engines were very successful and the reliability and stability of the already-established Korean-style high-thrust solid-fuel engine designing and manufacturing technologies were clearly verified once again," the KCNA said.
"The test provided a sure guarantee for reliably accelerating the development of the new-type IRBM system," it said.
The KCNA said the North's General Missile Bureau attached "great significance" to the development at a time the country faces a "grave and unstable security environment" and "vicious" military collusion among its enemies.
Analysts said the latest tests may be part of such attempts to advance its weapons system in the face of growing trilateral security cooperation among Seoul, Washington and Tokyo.
An IRBM, which can fly some 4,000 kilometers, goes beyond the Korean Peninsula and puts the U.S. territory of Guam within range.
"It appears to be attempting to develop its weak intermediate-range missiles to increase deterrence against the U.S," Hong Min, a senior research fellow at the Korea Institute for National Unification, said, noting how the North's intermediate-range missiles had been liquid-fuel types.
Solid-fuel missiles are known to be quicker to launch and harder to detect ahead of launch compared with liquid-fuel types.
With the North having announced the successful test of the first- and second-stage engines, the recalcitrant regime may attempt to test-launch a solid-fuel IRBM soon as it marks "missile industry day."
Earlier this month, the North designated a "missile industry day" to mark the anniversary of its test-firing of the Hwasong-17 intercontinental ballistic missile on Nov. 18 last year.
The US has tried to hold joint drills with South Korea over years. This issue also provokes North Korea to launch a number of missiles to show its defence capability.
What the United States has always tried to do is to constitute provocation in Asia, and it is fond of meddlesome in the Asian region's affairs. US security policy in the Asia-Pacific region directly affects China’s security interests as well.
It is the US that invented “coercive diplomacy” and excels at coercing countries. Over the years, by imposing economic blockade, unilateral sanctions and other means, the US has practiced coercive diplomacy around the world.
