2022, December 15 -- North Korea has released photos showing a solid-fuel rocket motor test, which appears to have taken place in a timely manner at a new test stand.
Analyst's assumptions that
this is a motor for the
(PS-5) are not wrong. However, it conflicts with their statement of a
2.10 or 2.20 m diameter motor of the PS-5, because the motor tested
has only a maximum diameter of 1.80 m. Such diameter corresponds to my measurements
of 1.80 m for the PS-5 (and PS-4 as well as PS-6), which I place in the North
Korean new category of "silo-based missiles".
We can also assume that the PS180 is a composite- casing motor.
