The K9 howitzer, celebrated for its impressive firepower, is significantly enhanced by its integral partner, the K10 ammunition supply vehicle. This K10 system is crucial in maximizing the K9’s battlefield effectiveness.
The K10 represents a major advancement as the world’s first fully automated ammunition supply vehicle, designed to replenish the K9 howitzer quickly. Built on the same chassis as the K9, the K10 can carry up to 104 rounds and deliver more than 12 rounds per minute to the howitzer.
The K10 features a three-person crew, automated inventory management, and a self-diagnostic control system. Its armor is rated to withstand 14.5 mm armor-piercing rounds and includes a comprehensive chemical, biological, radiological, and nuclear (CBRN) protection system. Each K10 unit is valued at approximately 2.68 billion KRW (around $2 million).
South Korea invested 12.7 billion KRW (about $9.5 million) in developing the K10. Hanwha Aerospace, formerly Samsung Techwin, led the project in collaboration with the Agency for Defense Development (ADD) and the Defense Quality Assurance Agency. Development began in 2002, and after 13 months of extensive testing, the K10 received operational approval from the Joint Chiefs of Staff in 2005, with the first unit deployed on November 20, 2006. The K9 howitzer operates with the K77 fire command vehicle as part of a comprehensive artillery system.
An Army official remarked, “The integration of the K9 howitzer, K77 fire command vehicle, and K10 ammunition supply vehicle has greatly enhanced our operational effectiveness.” The development of the K10 has had a significant domestic production impact, generating 1.25 trillion KRW (around $930 million), and it has become a flagship product of the South Korean defense industry. The K10 has also seen successful exports to Poland, Turkey, and Australia.
K10, K9 Howitzer, and K77 Fire Command Vehicle: Premium Artillery Systems
The K10 ammunition supply vehicle, along with the K9 howitzer and the K77 fire command vehicle, is recognized as a leading artillery system, according to Jane’s Yearbook, a prominent global defense publication based in the UK.
Historically, the role of ammunition supply vehicles was not clearly defined, often leading to their classification as distinct weapon systems. Before the 1970s, trucks were the primary means for delivering ammunition to tactical positions. However, these trucks often struggled to reach firing positions directly, forcing soldiers to transfer ammunition from the vehicles to the howitzers manually.
This manual process was labor-intensive and caused significant fatigue among troops, mainly due to the heavy weight of some rounds, which could reach up to 110 lbs (50 kg). With the advent of armored self-propelled howitzers like the U.S. M109 155 mm in the 1980s, traditional wheeled trucks’ mobility and protection limitations became evident, diminishing their effectiveness in operational scenarios.
The emergence of self-propelled howitzers highlighted the need for an ammunition supply vehicle to match their mobility and protection. This development aimed to create a reliable supply system capable of keeping pace with mobile artillery units over extensive operational areas, thereby fully utilizing the advanced capabilities of modern high-performance artillery systems.
Automated Resupply System of the K10: Efficiency in Action
The K10’s advanced automated resupply process is a key feature of its design, enhancing its operational efficiency. At the heart of this system is a computerized conveyor that links the vehicle’s ammunition storage to the supply point. Historically, wheeled trucks were employed to transport ammunition to Ammunition Transfer Points (ATP) and collection points. Once the ammunition reached these locations, the K10 took over, managing the movement and resupply between the collection point and the firing position. It also handles the final manual loading of ammunition at the collection point.
Built to operate across diverse terrains, the K10 excels in resupply missions on uneven ground. Upon receiving an assignment, an automated robot within the K10 manages the resupply process. The K9 howitzer, equipped with a resupply hatch at the rear of its turret, allows the K10’s conveyor system to connect directly. The robot loads ammunition onto the conveyor, delivering it to the K9.
The K10 can resupply at a rate of up to 12 rounds per minute. A full resupply, including both rounds and propellant, takes approximately 28 minutes. The entire process, from the supply point to the K10, is completed in about 40 minutes.
The K10 addresses the delays and inefficiencies associated with using 5-ton trucks and manual labor for ammunition resupply. By reducing soldier fatigue and enhancing operational efficiency, the K10 significantly bolsters the military’s capacity to conduct effective firepower operations in combat.
K10’s Critical Role and Superior Mobility
The K9 howitzers’ most vulnerable phase is ammunition resupply. A critical example is the 2010 Yeonpyeong Island shelling incident, where only six K9 howitzers were stationed at the Marine Corps unit, and no K10 ammunition supply vehicles were available. This left Marines manually transporting ammunition from trucks to howitzers under direct threat, exposing them to significant risk during the surprise attack.
In terms of mobility, the K10 benefits from being built on the same chassis and engine as the K9, ensuring it matches the K9’s mobility capabilities. This compatibility means that wherever the K9 can operate, the K10 can follow. Its tracked design allows the K10 to navigate rugged terrains where traditional 5-ton ammunition supply trucks struggle, enhancing its effectiveness in challenging field conditions.
Another key advantage of the K10 is its level of protection. It offers the same defense against 14.5 mm caliber rounds as the K9 howitzer. In contrast, 5-ton trucks often lack adequate protection from small arms fire, necessitating additional escort troops during transport and leaving them vulnerable to surprise attacks.
The K10 is engineered to withstand heavy-caliber fire from medium machine guns, although caution is advised against threats like RPG-7 anti-tank rockets. It is well-protected against infantry weapons and is equipped with a K6 machine gun for self-defense, allowing it to respond to threats effectively. Its rapid navigation through hazardous areas remains its greatest strength, ensuring reliable resupply operations.
Current military reports indicate that up to three K10s are deployed per battery of six howitzers, though the number may vary based on specific operational needs.
