HM-41 is an Iranian 155 mm howitzer based on the KH179, which was imported from South Korea during the Iran-Iraq War. It has a 155 mm/39 caliber barrel with a muzzle brake to lessen the recoil.
According to Iranian sources, the HM-41 weighs 6,890 kg, the same weight as the South Korean KH179. The HM-41's main components are also very similar in appearance to the KH179's CN79 barrel, RM79 recoil buffer, and CG79 mount and firing a rocket-assisted High-Explosive (HE) projectile, a maximum range of 30 km can be achieved. Firing an unassisted HE projectile, a maximum range of 22 km can be obtained.
The HM-41 has been offered for export, but no country is known to be using it except Iran.
Development
