What is known is that it is a 180 mm (~ 7 ") self-propelled gun of the open turret type. It was first seen publicly during a military parade in 1985. At least one example has been acquired by the United States.
The 180 mm gun itself is a previously 180 mm gun S-23, Soviet Heavy gun.
In 1989, a new version of the Koksan appeared, that was designated the M-1989. The main difference was a chassis from T-62 produced under the license of the USSR in the DPRK. That allows 12 rounds of ammunition to be carried. It carries a crew of four; the remaining four personnel needed to man the gun ride in an accompanying ammunition and support vehicle.
Little is publicly known about how North Korea organizes and deploys its artillery. It has been suggested that M-1978's and M-1989's equipped battalions consist of 12 guns, 20-30 trucks and 150-190 personnel, organized into a battalion headquarters and three batteries with four guns per battery. Battalions are organized into a brigade consisting of 3 to 6 battalions. The brigade has a brigade headquarters and supporting engineer, air-defense and target acquisition units.
In 1987, several M-1978s were supplied to Iran, and used during the Iran–Iraq War. When using rocket-assisted projectiles, a range of almost 60 kilometres (37 mi) could be achieved, making the weapon the world's longest-ranged field artillery piece at the time. Iranian forces used them to carry out long-range harassment fire against Kuwaiti oil fields.
A number of the Iranian guns were subsequently captured by the Iraqis and placed on public display. At least one of these was recovered by US Marines in 2008 from the campus of the University of Anbar.
