Among KMK45 components, the slide body is a welding structure in which firing system components such as gun barrel, gun barrel housing, and recoil-counterrecoil assembly are assembled and was introduced by BAE Systems, but Hyundai Wia, which produces KMK45 in Korea, has been developing localization through a localization development project for general parts since November 2016 to improve the localization rate and shorten the production schedule.
Previously, the main components mentioned above were assembled on the slide body to form a slide assembly, and then a general ammunition firing test was conducted at Anheung test site of the Agency for Defense Development, and a high-pressure firing test was completed at the U.S. Navy firing test site before being put into the assembly process. It is proposed to develop a test and evaluation for high-pressure ammunition firing test so that it can be carried out in a domestic test environment.
