The K105A1 features digital fire control, GPS/INS systems, decreased deployment time and a significantly reduced number of crewman.
South Korea is among the largest operators of the M101 howitzer, with around 2,000 in service. To make the most of the remaining value of these weapons, Korea developed the K105A1 wheeled self-propelled howitzer. Initially called the EVO-105, the weapon system is mounted on a Kia K711A1 5-ton truck chassis.
The structure of the truck compartment was improved, adding a higher armored compartment behind the cab, with a self-defense machine gun on the top, and the artillery installed in the middle of the compartment. It has a new automatic fire control system to increase its immediate response. Speed, the ammunition box on the car can carry 60 rounds of ammunition, even if there is no ammunition supply car, there is a strong continuous combat capability. In order to stabilize the shooting platform, hydraulic outriggers are also installed on the vehicle.
The vehicle provides protection against light fire and shrapnel. When compared to its base 105mm towed howitzer, crew has been reduced from 9 to 5 and requires much less time & preparation to fire due to automated digital fire control system. When the vehicle is parked in the combat position, it can complete the shooting preparation within 30 seconds after receiving the firing command.
The M101 howitzer has been refurbished, but the barrel, ammunition and other parts of the howitzer have not been changed, so the maximum range of the gun is only about 11 kilometers. The maximum rate of fire is 10 rounds per minute. There are three modes of loading: manual, semi-automatic and fully automatic.
The K105A1 features digital fire control, GPS/INS systems, decreased deployment time and a significantly reduced number of crewman. The K105A1 is intended to be distributed among infantry divisions as brigade-level fire support asset. The system is extremely fast into action, requiring less than sixty seconds to stop and shoot, versus four and a half minutes for its towed counterpart. There is no need to dig a recoil pit, and the weapon retains its high angle of elevation.
The K105A1 wheeled self-propelled howitzer has a combat weight of 18 tons. This truck is driven by a 270-horsepower 6-cylinder diesel engine for a maximum speed of 85 km/h. Currently about 850 systems have been manufactured by Samsung Techwin, and they will replace the 106mm mortars equipped in the infantry division and provide stronger support artillery for the troops.
