Looking at the photos released by North Korea, it can be seen that the vertical missile launch tube (VLS) consists of four large and six small tubes, which can be used to launch at least two types of missiles.
Chairman Kim Jong Un introduced that North Korea's submarine policy in the past was to build many small and fast submarines to defend its territorial waters, and said that the role of the navy has also changed with the times, adding, "Today's launch ceremony is no less than our construction of a new nuclear-powered submarine." “It will be a burden to our opponents,” he predicted.
Here he emphasized the need to decisively solve the ship engine problem by creating a modern engine industry.
The rear of the submarine was covered, which appears to be an intention to not reveal the shape of the screw. The screw shape is also the most important confidential information in ship construction. The shape of the screw allows the other side to detect the submarine using sound waves.
An impressive 10 missiles loadout, probably 4 x Pukguksong-1/3 SLBM and 6 x Hwasong-11S aeroballistics missiles or 6 x Hwasal-2 SLCM.

North Korea's Hero Kim Kun Ok SSB upper structure was inspired by the Chinese Type 035's sail, but did not redesign the tail like the Type 035. Thanks to the streamlined tail drag is reduced and the sub has higher submerged speed than Type-033/Romeo.

One aspect that seems quite modern is the bow. Unlike the Type 033/Romeo bow it's dome shaped and likely to accommodate a more modern sonar array.

▲ If the diameter of the submarine's hull remains unchanged (which is highly likely), the increase in length of the new submarine is staggering. The red line represents the Type 633 submarine. · Sep 8, 2023

China Navy Type 033 Romeo class Attack Submarine SSK
Displacement: 1475 tons (surfaced) / 1830 tons (submerged) ; Length: 76.6 meters (703 pixels); Beam: 6.7 m
DPRK Navy submarine No. 841 Hero Kim Kun Ok SSB
Displacement: 3,000 tons ; Length: ~96.2 meters (883 pixels); Beam: 6.7 m
▲ Meanwhile satellite image taken 6th April 2023 allowing better measurements with Google Map indicate a length closer to 80 m rather than 96 m.
▲ North Korean submarines 2023. Estimated strength. Better measurements with Google Map indicate a length closer to 80 m.
