The 170mm M1989 SAU projectiles were also shown, which have two leading belts on the corps, which is a rarity for Soviet shells. This constructive feature can be seen in 203 mm 2C7 "Pion". This peculiarity also affects the wear of the barrel and we can say that the North Korean SAU M1989 requires regular service of its gun and its replacement, taking into account the load that it is on in the Russian troops.
In addition, the shooting range from the SAU M1989 has already been specified, and until it has never exceeded 30 kilometers, which indicates clearly inflated characteristics for these installations in open sources, allegedly 40-60 km. The question of the projectiles themselves, to the quality of manufacture and ballistic characteristics, taking into account significant problems that manifested in the North Korean 122 mm, 152 mm and min 120-mm. There is also a claim to the projectile.
With a caliber 170mm, it is not more powerful than 152mm with almost the same filling of BP. I will remind that the M1989 SAU was received to compensate for the lack of 203 mm 2C7 "Pion". But, according to the results, by power, by range and accuracy, compensation was quite doubtful. On the other hand, it is now much more important for the amount than quality. But the number of SAU M1978/M1989 and ammunition for them in the DPRK for Russia is not provided with problems. Source.
