Developed during the tense years of the Cold War and first deployed during the Vietnam War, the MK 19 Automatic Grenade Launcher has become one of the most trusted support weapons in modern military arsenals. Chambered in 40mm and belt-fed, the MK 19 offers high firepower, a wide range of ammunition types, and compatibility with multiple platforms, making it a vital asset for both infantry units and armored vehicles in contemporary combat environments.
Tactical and Technical Features
The MK 19 has an effective range of approximately 1,500 meters and a maximum range of 2,212 meters, allowing it to engage both medium- and long-distance targets with precision. To ensure operational safety, a minimum safe firing distance of 75 meters is recommended, depending on the type of ammunition used.
Equipped with a specially designed barrel featuring 24 lands and 24 grooves, the weapon delivers exceptional accuracy and projectile stability. It operates in both single-shot and fully automatic firing modes, offering flexibility in various combat scenarios.
Ammunition and Effects
One of the MK 19’s key advantages is its ability to fire a wide variety of munitions. These include anti-personnel and armor-piercing rounds, available in both conventional high-explosive and self-destruct fuse variants. Some munitions are so sensitive that they can detonate if accidentally dropped, highlighting the importance of cautious handling and transport.
Self-destruct fuzes ensure that even if a round fails to detonate on impact, it will explode after a short delay. This is particularly useful in soft terrain—such as snow—where the lack of a solid surface might otherwise prevent detonation, thus enhancing safety and effectiveness in diverse environments.
Deployment and Integration
Due to its 272 kg recoil force, the MK 19 must be firmly stabilized before firing. In the field, it is typically mounted on a tripod for ground use, though versions integrated into turrets on armored vehicles are also widespread.
With advancing defense technologies, the MK 19 has been successfully integrated into Remote Weapon Stations (RWS), enabling its deployment on armored vehicles and fixed defense positions. It is currently in active use by many countries, including the Turkish Armed Forces (TSK) and General Directorate of Security (EGM) in Turkey.
Night Vision and Sight Systems
The MK 19 is designed to be compatible with advanced optics and targeting systems. It can be outfitted with the AN/TVS-5 night vision system as well as a range of digital and optical sights, allowing for high-precision operations even in low-visibility conditions.
The MK 19 Automatic Grenade Launcher stands out as an indispensable support weapon in modern warfare, thanks to its powerful ammunition capabilities, versatile firing options, and seamless integration across multiple platforms. Its devastating firepower and adaptability make it particularly valuable in border security, base defense, and armored unit support, ensuring its continued role in military doctrines for years to come.
