Development
The KH179 is a towed howitzer developed and produced by Kia Precision Industry (now Hyundai WIA) since 1983 for the purpose of replacing the U.S. M114A2 towed howitzer and enhancing artillery firepower.
General characteristics
The KH179 makes use of lightweight components (CN79 barrel, RM79 recoil buffer, and CG79 mount) and can be air-transported by CH-47 chinook helicopter and C-130 transport aircraft. In addition, performance improvements were made in range, reliability, and maintenance compared to conventional M114A2 howitzers operated by the South Korean military. The ammunition used in the KH179 is compatible with NATO 155 mm standard ammunition, but has significantly improved range and firepower.
It is equipped with a direct/indirect aiming mirror, allowing both direct and indirect howitzer firing. Direct fire uses an L-type aiming mirror with 3.5 magnification and has an effective range of 1,500 m. Indirect shooting uses a four-magnification panoramic aim mirror mounted on the left. The range is 18.1 km for normal rounds, 30 km for rocket-assisted rounds, and the firing rate is 2 rounds per minute for continuous shots, and the maximum firing rate is 4 rounds per minute.
