PKMs consisting of 'Chamsuri' class ships started becoming localized in the 1970s. The initial types were equipped with 20-mm Vulcan Automatic Cannons in the front and 40-mm Bofors cannons in the back. The types that came after had 2 30-mm Emercen extended cannons at the front and 2 20-mm Vulcan automatic cannons at the back. The latter types were equipped with 40-mm Bofors cannons (cover types) at the front instead of the 30-mm cannons. Optical aiming systems were used for fire control at first, but recently the system has been automated with the introduction of the Fire Control System (FCS).
