rtr3u1xlEvidence has appeared in recent commercial imagery that a new North Korean submarine has up to two vertical launch missile submarines. A website run by the US-Korea Institute at the Johns Hopkins School of Advanced International Studies called 38 North posted the imagery with tags showing how the conning tower of a new North Korean submarine can house 1–2 ballistic or cruise missile tubes. The submarine was seen at the Sinpo South Shipyard in North Korea, which has seen significant infrastructural improvement recently. Officials at the US Korea Institute at SAIS speculated that a “shorter naval version of the Musudan intermediate-range ballistic missile, a Nodong medium-range ballistic missile, or naval versions of the solid-fuelled KN-02 short-range ballistic missile” could be the missile used aboard the submarine.
