Both South Korea and U.S. intelligence authorities assess that North Korea is reviewing the right timing to roll out the submarine for a strategic effect, including maximizing pressure against the United States.
U.S. think tank said DPR Korea has moved a submersible missile test barge at its missile test site to a different position, possibly indicating an upcoming test of a submarine-launched ballistic missile (SLBM).
The source added that the North could reveal the submarine at a launching ceremony and actually roll out an SLBM, such as the Pukguksong-3.
On October 10, 2020, during the night military parade in Pyongyang, North Korea demonstrated a new intercontinental ballistic missile (ICBM).
As it was reported, North Korea launched two ballistic missiles into the sea near Japan, fueling tension ahead of the Tokyo Olympics and ramping up pressure on the Biden administration as it finalizes its North Korea policy.
