THREAD: DPRK held a defence exhibition on 11 Oct. Most weapons displayed had been shown before. This thread highlights some of the exhibits showcased in the event. KCNA
1. New-type ICBM that made its public debut on 10 Oct 2020 but has yet to be flight tested.
For more info see: thebulletin.org/2020/10/two-ke… KCNA
2. Hwasong-8 tested on 28 Sept 2021 was displayed among the ICBMs and IRBMs. Photo shows that its hypersonic glide vehicle looks similar to the Chinese DF-17.
For more info see: bit.ly/3AAbq2T KCNAAFP
3. The missile referred to as KN-23 and KN-24 and a bigger, newer short range boost-glide ballistic missile were also displayed. The KCNA’s language in describing the KN-23 and KN-24 have been very different.
See: bit.ly/3lzWEVi KCNA
4. It is worth noting that we now have an official name for the KN-24: Hwasong-11NA [화성포-11나]. Previously, some suspected that Hwasong-11 is a designation for another short-range missile system. KCNA
5. The ~600mm super-large calibre multiple rocket launcher system (also referred to as KN-25) on tracked and truck chassis is also displayed. The KN-25 rocket has six wrap-around fins. Every two of the fins form a pair of brackets.
See: bit.ly/2X80eNg KCNA
6. There appear to be two types of radars for surface to air missile (SAM) systems among the exhibits. It is possible that one of the radars was present in the 30 Sept 2021 test of a new-type surface to air missile. KCNAKCNAKCNAKCNA
7. New type long-range cruise missiles reportedly tested on 11-12 Sept 2021 was also showcased.
For more info on the test launches, see: bit.ly/2YI9VCx KCNAKCNA
8. New type SAM has 3 sets of wings and fins. KCNA reported that the missile employs “twin-rudder control.” An initial observation was that the missile might employ a canard design similar to Soviet SA-3. This assessment needs to be revised.
See: bit.ly/3FEPaIL KCNAKCNA
9. Another 2 unseen new items in this photo: a smaller missile [red], possibly also submarine-launched, was placed next to the Pukguksong-series SLBMs. Left to the SLBMs is a previously unseen vehicle with four aerodynamic surfaces and a conical, slim body [yellow]. KCNA
10. Other exhibits included anti-ship missiles [red], other artillery pieces (for example, the KN-09 in yellow) and other weapons that have been showcased on previous occasions.

1. While much attention this week has been on the 🇰🇵’s paraded missiles, 🇰🇷 is continuing to progress in the development of its own missile programme. 🇰🇷 likely conducted tests for its new ‘high-power’ Hyunmoo, also known as Hyunmoo-5, in recent days.
2. @planet imagery shows a probable missile launcher on the launch pad at the Agency for Defence Development’s (ADD) test site on 31 January, one day before reporting on a planned launch for 3 February started appearing in South Korean media. en.yna.co.kr/view/AEN202302… Image
3. The ~20m launcher appears ~5m longer than the one likely used in a 2020 Hyunmoo-4 test at the same location. This would be consistent with an improvement in performance, in line with the reported increase in warhead weight from 4-5t to 8-9t. opennuclear.org/publication/so… Image

DPRK State media reported on Monday on the country’s missile launch campaign from 2 to 5 Nov 2022. ONN has compiled the following information regarding the launches based on information provided by Japan, the ROK and the DPRK.
As can be seen from the table above, there are some discrepancies in the information provided by the 3 different countries. The ROK claimed the DPRK’s report on the “strategic cruise missile” launches to be false.

A comparison of the launch photos also proves that the DPRK re-used an old photo (first published in April 2022) in its report covering its Nov launch campaign. (as first noticed by @rockfish31) Such practices reduce the credibility of the DPRK’s announcement.

1. On 24 Mar 2022, the #DPRK conducted an apparently successful test of an international ballistic missile (#ICBM). This was the first such test since Nov 2017 and marked the official end to the DPRK ICBM and nuclear test moratorium.
2. According to 🇺🇸JCS and 🇯🇵MoD, the ICBM was launched at ~2:33 pm local time. It followed a highly lofted trajectory, with an apogee of >6200 km before splashing down ~150 km west of 🇯🇵Toshima Peninsula, 1080 km from its launch site at 🇰🇵Sunan airfield. The flight took ~71 min.
3. Considering that the apogee is significantly higher than previous tests, the 24 Mar test probably involves the new ICBM that made its debut during a military parade on 10 Oct 2020. The name of this new system is possibly Hwasong-17.

1. DPRK just released an official image of the ballistic missile tested on 5 Jan (pic 1). It appears to be the new hypersonic weapon first revealed during the Oct 2021 weapon exhibition (marked as Missile B in pic 2). Full ONN report on the exhibition: bit.ly/3HBIM5l KCNAKCNA
2. Same as the Hwasong-12, the missile is carried by a MAZ-547 truck. However, the missile appears to be much shorter than the HS-12, as evidenced by the clips on the erection arms: they have been moved back to hold the shorter missile (see pic below) KCNA
3. In general, the new hypersonic missile seems to be of similar length to the Hwasong-8 hypersonic missile tested in Sept last year (see pic 1 below). The Hwasong-8 also appears to be significantly shorter than the Hwasong-12 (pic 2). For more info see: bit.ly/3n1RAJP KCNAKCNA
