韓国・防衛事業庁(DAPA):

韓国の防衛事業庁(DAPA)が、11月13日声明を発表しました。

大韓民国(RoK)軍とRoK海兵隊に配備された、K9の数は、明らかにされていません。

ジェーンズの推計:

1999年以降、1,300台が、韓国軍に引き渡されたと、推測しています。

The K9 family of armoured SPHs

was designed and initially manufactured by Samsung Techwin to provide a modernised system

that would be better suited to counter the threats posed by North Korea.

The K9 was first deployed in 1999 to the western border islands of Yeonpyeong and Baengnyeong.

According to Janes Land Warfare Platforms:

Artillery and Air Defence, the 46.3-tonne K9

is designed to provide an armoured force with the indirect fire required to defeat conventionally equipped opponents.

The range of the system using standard ammunition

is 18 km, but this can be extended to 30 km through rocket assisted projectiles, or to 40.6 km using advanced base-bleed ammunition.
