H I Sutton's September 8, 2023 article, on the September 6 launch of North Korea's (NK's) possible 10 missile SSB, is most interesting.
My inititial thoughts are the SSB (especially in main picture below) looks too top heavy (submerged or surfaced) to be a stable missile firing platform. It may be a propaganda response to South Korea's 10 missile KSS-III Batch 2 SSB.
So it is unclear if this NK SSB has the stability to fire its missiles (then its VLS tubes are presumably backfilled with water?) and then be able to surface without dangerously leaning on its side.
To avoid such a happening the following information, of September 8, 2023, from 38 North may be very significant:
"Just 24 hours later, on September 7, in a
puzzling occurrence, the submersible ballistic missile test barge had been
moved from the south protected basin and was nested outboard of the newly
launched submarine."
This may suggest that NK may soon film firings of new larger (Pukguksong 4 or 5?) missiles purportedly launched by the SSB. But actually fired from the submersible ballistic missile test barge.
This propaganda hoax will then be believed by much of the Western mainstream media.
