-- Commercial satellite imagery indicates that North Korea preparing the Sohae
Satellite Launching Station (“Tongchang-ri”) for launching of a new larger space
launch vehicle. The Sohae gantry tower has been undergoing significant modifications.
So will be increased the gantry about three sections of 46 m to 60 m (without
2017, December (SEOUL) -- North Korea will launching its new large SLV in September 2018, said a South Korean source. The new rocket would be an larger as the Unha-3. A "defector" said the new missile would be considered the "Unha-4". Development of the rocket body is all but complete, but it is expected to take about months to prepare for a launch.
Note: Probably we already saw the two upper stages of the new SLV in the test. (HS-15)
2017, March 19 -- North Korea has successfully conducted the ground test of its new rocket engine in fully modus (still without the second combustor), added with four steering engines. According to the North Korean news agency KCNA, the test measured the thrust power in the combustion chamber, the structural safety and reliability of the engine, and the movement of the turbine.
2016, Sept. 20 -- North
Korea has successfully conducted the ground test of a new
rocket engine, the country's state news agency reported.
North Korean leader Kim Jong-Un visited the Sohae Space Center to guide the test of "a new type high-power engine of a carrier rocket for the geo-stationary satellite," the Korean Central News Agency (KCNA) said.
This test was “aimed to make a final confirmation of the feature of combustion chamber, operation accuracy of valves and control systems and structural reliability of the engine during 200 seconds-long working time". North Korea also says the engine has a thrust of 80 tons of force ! However, this refers to twin-combustor arrangement.
What was previously just a guess, seems to be confirmed: North Korea has at
least blueprints of an old Soviet ICBM engine. The new North Korean engine "Pektusan"
is clearly comparable to the RD-250 engine
of the KB Glushko. Two combustors use a common turbopump. Typical is the low
arrangement of the TP between the nozzles.
