M-1978 Koksan (Korean: M-1978 곡산; Hanja: M-1978 谷山), a name used by US military analysts, known by its makers as the Church'ep'o (Juche Cannon; Korean: 주체포; Hanja: 主體砲), is a North Korean self-propelled 170 mm (6.7 in) gun based on the Type 59 tank chassis.
Some guns were exported to Middle Eastern countries in the late 1980s and used during the Iran–Iraq War. The M-1989 Koksan variant has seen use in the Russo-Ukrainian war.
