Is North Korea's new monstrous
MLRS ("Pukguksong MLRS") a stretched Russian OTR Totchka (9M79) ?
2019, Sept. 10 -- On this day
North Korea fired missiles from its MLRS for the third time.
2019, Aug. 24 -- For the first
time, North Korea presented detailed images of the new monstrous rocket of
an MLRS, firing for the third time on this day. Unlike before (Juny 31 and
Aug. 02), the launch of two missiles each from a 4-tube system (2 on 2), which
is mounted on a vehicle with 6 wheels. The 3-tube system was before mounted
on a wide tracked vehicle with 10 axles. The term "monstrous" refers to the
unusual dimensions of the missile of this MLRS (KN-25).
What is the origin of this rocket ?
It is reported about a diameter of the tubes of about 70 cm, which
could correspond to the facts. This suggests that the rocket has a diameter
of about 60-65 cm. Since it is unlikely that North Korea has developed
a completely new motor of this diameter, we should assume an existing
solid-fuel motor. In this case, the motor of the Russian OTR
offers, which is demonstrably available to North Korea. The uncertainty,
however, is whether the originaly nozzle withstands the thrust of a longer
OTR "Totchka" (9M79
The "Totchka" motor has a diameter of 62 cm. If parts of motors for
the OTR Totchka welded 3 times in a row results
in the dimension (~ 8 m) a match with the photos of the rocket. The problem
with the bulky 6 fins in the tube was solved elegantly.
We can see that the rocket has in the tube six round-folded fins,
fixed by brackets.
