Current business satellite tv for pc imagery reveals uneven progress within the growth and modernization of North Korea’s Sohae Satellite tv for pc Launching Station. Since our final full website report in March 2025, work has continued on ending the seaport and connecting it to the primary Sohae complicated. Exercise across the vertical engine check stand signifies a small engine check was performed lately, though none have been reported in North Korean state media thus far. Progress on different areas, resembling the brand new meeting constructing and the previous launch pad space, seems to have slowed.
North Korea has not reported a reconnaissance satellite tv for pc launch try for the reason that failed launch of the Malligyong-1-1 in Might 2024, and no indicators of an imminent launch have been noticed.
Kim Jong Un had as soon as introduced a purpose of launching three extra reconnaissance satellites by the top of 2024. That deadline handed with out success. It’s value noting that in September 2023, in the course of the Putin-Kim summit on the Vostochny Cosmodrome, Russia expressed a willingness to assist North Korea’s satellite tv for pc program. This lengthy delay in additional launches could also be an indication that cooperation is underway.
Vertical Engine Check Stand (VETS)
Imagery from September 27 and 29 revealed {that a} rocket engine check had taken place on the VETS.
On September 27, the cellular shelter was seen pulled again from the stand and a truck and cellular crane had been seen parked on the pad. An unidentified object was noticed within the truck mattress. A number of service carts with hoses or doable cabling had been seen mendacity on the close by tarmac.
By September 29, the shelter had been returned to its typical place and there have been no indicators of auto visitors.
Imagery from October 4 revealed restricted burn marks within the exhaust bucket, suggesting a check of a smaller, higher stage rocket engine had occurred. The orange residue means that the engine makes use of gasoline and nitric acid or nitrogen tetroxide oxidizer. China and Russia, together with North Korea, extensively use UDMH gasoline of their launch autos. Seen orange stain streaks from gasoline and oxidizer, together with streaks from cooling the engine exhaust, are noticed within the flame bucket.
Different Developments
Building exercise first reported in March 2025 continues to progress, however at a slower tempo than beforehand noticed. The docking slip on the seaport to accommodate massive vessels seems to be full, reaching into the ocean to keep away from impacts of extreme tides. Rails situated alongside both facet of the slip will probably assist an overhead, touring gantry crane. A. This can be to assist a heavier crane base on the north facet to higher assist the crane in transferring hundreds from vessels onto vans. As well as, 5 lattice masts have been erected alongside both facet of the pier, prone to assist flood lights. The coastal highway main from the port to the launching station is now fully paved.
Imagery from March 2025 indicated a brand new part of highway was being excavated to affix the east tunnel entrance to the coastal highway, although as of early October 2025, it has but to be accomplished. The sluggish progress could also be because of the quantity of earth needing to be eliminated to affix the 2 factors due to the mountainous terrain. It additionally stays to be seen whether or not this passage will simply be a highway or if it is going to additionally assist a rail spur. has been ready nearer to the coastal launch pad, comparable in width to the present highway. The aim of this is unclear.
An roughly 2,400 square-meter space has been constructed up alongside the west facet of the highway, which can function a handy location for depositing the rubble from the lower by means of, or function the inspiration for a assist construction.
As well as, a loop highway has been added instantly north of the east tunnel entrance. There’s unidentified development at its mid-point alongside the hillside.
Slowed Exercise
Building progress on the brand new receipt and meeting constructing, the west tunnel entrance, and the brand new rail spur that may join each to the primary rail line coming into the positioning has modified little since March. The facet rooms lining the brand new receipt meeting constructing had been left uncovered within the spring, and plenty of have but to be roofed. As well as, each the rail mattress supporting the brand new spur and west tunnel entrance have seen little change. It’s unclear why progress on these tasks has slowed.
No Motion
No exercise on the authentic launch pad or the close by gasoline/oxidizer bunkers and assist buildings have been noticed in current months.
Likewise, on the authentic horizontal meeting and storage constructing, the 12 cylindrical storage tanks that had been first noticed in July 2023 have but to be moved. The rail spur which beforehand serviced the primary launch pad, has been truncated and the remaining portion falling into disrepair. This implies for now, the one method to transfer rocket levels from the positioning’s rail switch station to the pad is by highway.
