The U.S. Army is set to enhance its MK19 grenade launcher by developing new munitions aimed specifically at counteracting small unmanned aerial systems (UAS). This enhancement comes amid a significant increase in counter-drone initiatives across Western military forces, heavily influenced by tactical experiences gleaned from the ongoing conflict in Ukraine.
In the next few days, the Army is expected to issue a cornerstone initiative request that will introduce a 40mm counter-unmanned aerial system capability. This ambitious project focuses on integrating advanced sensing-fuze technology into programmable air-burst rounds designed for the MK19. The goal is to create a comprehensive system capable of targeting and neutralizing small drone threats effectively.
The innovative sensing-fuze technology employs integrated sensors to detect and assess the proximity of targets. This allows for detonation at an optimal distance, thereby maximizing the impact and effectiveness of each round without necessitating direct contact with the target.
“This necessitates the development of a fully integrated system encompassing detection, tracking, targeting, and defeat functionalities,” the solicitation from the U.S. Army articulated. It emphasized the critical requirement for seamless compatibility with existing weapon platforms, fire control systems, and remote weapon stations, creating a cohesive counter-drone defense mechanism.
The MK19 grenade launcher, first designed during the Vietnam War, is a belt-fed, automatic weapon that fires 40mm grenades at a cyclic rate of 325 to 375 rounds per minute. With an effective point-target range of about 1,500 meters and a maximum range of 2,212 meters, it boasts substantial firepower.
Once armed with a counter-drone cartridge, the MK19 is anticipated to deliver capabilities similar to those provided by the Advanced Precision Kill Weapon System. This system utilizes an L3Harris guidance and fuze kit to convert the Hydra 70 rocket into an efficient and combat-ready solution for countering UAS threats.
The formal solicitation process is slated to begin on or after November 25, marking the beginning of a selection phase for interested offers. Those chosen will present their proposals to a government panel before potentially entering a 48-month performance period. Following a successful prototype evaluation, a non-competitive award may be granted, further advancing the Army’s counter-drone capabilities.
