North Korea's large "Pukguksong-3" two
stage solid-fuel SLBM
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 signals that it is a GLBM.
03 -- North Korea has posted pictures of the successful launch the Pukguksong-3
SLBM on 2nd October 2019. It is a test version, without reentry warhead, nor
the skirt with grid-fins. The launch was made from an underwater barge. For
loading of this missile into a submarine is a larger class required. Such
is under construction, as recently published pictures suggest.
2019, September 13 --
Due to the recently unequivocally determined
tires of the transporter with the missile on the parade in April 2017 we have
to report a diameter of 1.4 m for a SLBM.
