Key Findings

  • A Maxar Technologies satellite image collected at 11:09 AM KST on April 6 shows that North Korea is moving its submersible missile test barge located at the Sinpo South Shipyard.
  • A search of a partial Planet image of the Sinpo area collected at 3:40 PM KST on April 6 shows that the barge has left the secure boat basin to the floating dry dock in front of the construction hall.
  • As no missile canister is visible onboard the submersible missile test barge, this movement does not indicate an imminent submarine launched ballistic missile (SLBM) test.
  • Probable reasons for this movement include:
    • Preparations for a forthcoming submarine launched ballistic missile test.
    • Movement of the test stand for maintenance, repairs, or installation of equipment.
  • The movement of the test stand barge, and the implied threat of renewed SLBM testing (potentially of a Pukkuksong-4 or -5), would present significant challenges to the new U.S. administration of President Biden and the administration of South Korean President Moon.
  • Further reporting on the overall Sinpo South Shipyard will follow.
