Das System ist ca. 50 Jahre alt. Bisher war es so, dass Nordkorea fast nur seine ältesten Munitionsbestände an Russland geliefert hat:

Even larger Ukrainian military outlets have been paying attention to the low quality of North Korean shells. According to the sources, North Korean-supplied 152-mm HE-frag shells failed to impress the Russian Army while undergoing quality control (Figures 10a-10d). The shells apparently have differing amounts of gunpowder, resulting in varying combustion dynamics and alternate ranges for the projectiles, as well as open sealing covers, which could lead to the presence of moisture in the shells.

While there are reports that North Korean factories are producing only new munitions for Russia, evidence from Russian Telegram channel administrators shows that only a portion of the munitions shipped by North Korea appear to be new.

Die Koksan hat zwar eine beeindruckende Reichweite von 40-50 km, die hängt aber halt auch von der Qualität der Munition ab. Und die Feuerrate liegt bei ca. 1 Schuss alle 5 Minuten. Zum Vergleich: Die deutsche Panzerhaubitze 2000 schafft 3 Schuss in 9 Sekunden bzw. 10 Schuss pro Minute. Bei der allgegenwärtigen Gefahr durch Drohnen gebe ich den Nordkoreaner keine lange Lebensdauer.
