North Korea heralded the successful development of a new “high-thrust engine” during a visit to the country’s rocket test site by leader Kim Jong Un, the reclusive nation’s state media said Sunday.

Kim observed the test of the indigenously built high-powered engine at the North’s Sohae satellite facility in Dongchang-ri on Saturday, according to the Korean Central News Agency.

The facility is near the site where the isolated country launched four extended-range Scud missiles earlier this month as part of a practice exercise aimed at striking U.S. military bases in Japan.

Kim said that the “development and completion of the engine would help consolidate the scientific and technological foundation to match the world-level satellite delivery capability,” the report said — an indication that the test was likely that of a long-range rocket engine.

KCNA said the purpose of the test was to confirm the reliability of the engine’s features, including its thrust power in the combustion chamber and the movements of various valves.

Rocket engines can be easily repurposed for use in missiles.

Pyongyang is banned by the U.N. from conducting long-range missile tests, but it claims its satellite program is for peaceful use, a claim many in the U.S. and elsewhere have called dubious.

KCNA quoted Kim as saying that the successful test was a “great event of historic significance” that marked the “new birth” of the country’s rocket industry as the North seeks to erase its dependence on other countries’ technology.

“The whole world will soon witness what eventful significance the great victory won today carries,” Kim said, according to KCNA.

In September, the North announced the successful ground test of a new type of “high-power engine,” ostensibly for launching satellites. State media said the engine could deliver 80 tons of thrust, making it likely the most powerful the country had ever seen.

David Schmerler, a researcher at the Center for Nonproliferation Studies at the Middlebury Institute of International Studies in California, said Saturday’s test was different from the engine tested last September.

“This appears to be a single-nozzle engine with four vernier thrusters,” Schmerler said, referring to thrusters used to maneuver and stabilize the spacecraft. “We haven’t seen this configuration before in North Korea.”

Schmerler said it could be a new second-stage engine for the North’s next satellite launch vehicle.

“However, it may also have a dual use in their ballistic missile program,” he added.

Pyongyang, March 19 (KCNA) — 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, watched the ground jet test of Korean-style high-thrust engine newly developed by the Academy of the National Defence Science.

After being told about the production of the new-type high-thrust engine, he personally visited the Sohae Satellite Launching Ground at dawn to learn in detail about the technical specifications of the engine and preparations for the test and guided it.

The test was conducted to confirm the overall technical indices of the engine such as features of thrust power in the combustion chamber, accurate movement of turbine pump, control system and various valves and their structural safety and reliability.

He mounted an observation post and gave an order to start the test.

The results of the test confirmed the stable maintenance of technical indices of all systems such as starting and stopping features of a new-type high-thrust engine of Korean style designed and manufactured by the defense scientists and technicians by their own efforts and with indigenous technology, the features of the thrust power in the combustion chamber, turbine pump, control systems in the whole course of engine operation after accurately reaching the expected values, and the perfect guarantee of their structural reliability. .

He noted that the success made in the current test marked a great event of historic significance as it declared a new birth of the Juche-based rocket industry which has radically turned into a development-and creation-oriented industry both in name and in reality by completely doing away with dogmatism, conservatism and formalism left in the field of rocket industry and the dependence on the technology of other countries.

He emphasized that the whole world will soon witness what eventful significance the great victory won today carries.

The development and completion of a new-type high-thrust engine would help consolidate the scientific and technological foundation to match the world-level satellite delivery capability in the field of outer space development, he noted, adding with pleasure that today when a great leaping forward has been made in the development of the rocket industry is the day to be always remembered, a historic day which can be called “March 18 revolution”.

He said that the field of munitions industry made a series of unprecedented successes this year as it did last year, instilling dynamism into the grand revolutionary advance of all the service personnel and people. Then he had a significant photo session with the officials, scientists and technicians in the field of defense science who took part in the test.

He was accompanied by Ri Pyong Chol, Kim Jong Sik and other leading officials of the C.C. the WPK and scientists and technicians in the field of rocket research. -0-
