MK-19 Grenade Machine Gun MODS

The MK-19 Grenade Machine Gun MODS program is a strategic initiative by the Army to enhance the lethality and operational capabilities of the MK19 grenade machine gun. This effort aligns with the Army's modernization priorities, focusing on building a more lethal force as outlined in the National Defense Strategy. The MK19 is a 40mm automatic grenade machine gun capable of firing 325-375 rounds per minute, engaging targets up to 1,500 meters, and providing suppressive fire at ranges up to 2,200 meters. The program aims to improve various aspects of the weapon system, including reliability, readiness, maintainability, and safety.

A key objective of this program is to implement system enhancements that increase operational capabilities. These enhancements include an improved mechanical sight through a Modification Work Order, which reduces logistical burdens and increases soldier lethality with updated ballistic solutions. Additionally, the Mounted Machine Gun Optic (MMO) aims to improve accuracy by equipping the MK19 with a combined reflex and magnified optic for mounted Combat Support & Combat Service Support troops. This enhancement is expected to significantly improve target identification and engagement time at extended ranges.

Further modifications include the development of MK93 Improvement Kits designed to enhance hit performance and improve soldier interface with optical sighting systems during vehicle engagements. The XM101 Programmer Unit provides fuze setting capabilities for the 40mm High Velocity, High Explosive Dual Purpose-Air Burst round, enhancing lethality against personnel targets in defilade positions. These modifications are intended to ensure that the MK19 remains effective in complex terrains and contested environments.

The program also addresses completed modifications funded in prior years, such as Tactical Engagement Simulators and legacy vehicle mounts. These efforts are part of a broader strategy to streamline submission documentation by focusing on current fiscal year development plans. The MK-19 Grenade Machine Gun MODS program represents a comprehensive approach to maintaining and enhancing the combat effectiveness of this critical weapon system within the Army's arsenal.
