The new "thick"
solid-fuel missiles Pukguksong-4 and
North Korean first silo-based

The same missile, but now with a longer shroud on top, was shown at the latest
parade. It is called "Pukguksong-5ㅅ". An escort team is missing because
the longer shroud is blocking the platform on the transporter. Another difference
could also be that the PS-4 did not have a real second stage. The PS-5 is
probably as well as the PS-4 a silo-based missile.
2020, October 10
-- At the parade
on the 75th anniversary of the founding of the Workers Party, a Pukguksong-4
was shown. It is not identical to the PS-3 SLBM. The PS-4 has a larger
diameter and the escort (Army) signals that it is a GLBM.
With the conclusive assumption that it is the transporter that was already
used with the PS-3 at the parade in 2017 (albeit now with a modified frame
and an additional axle), the diameter of the PS-4 is 1.80 m to measure.
The length would be 9.8 m. The twin-tires have the same diameter as before
of 1.04 m, but with different profile.
It is doubt that this thing is a real missile. No separation
mechanism can be seen at the shroud, only a flange. It is likely that
a new solid-fuel motor in the guise of a missile was prepared for the
missile is believed to be labeled "Pukguksong-4ㅅ",
featuring a Korean letter.
Is it a letter "S" in the Korean alphabet standing
here for silo ?
The logo on the escort's uniforms is unmistakable.
The PS4 is probably a silo-based missile.
