T


he United States continues to arm Ukraine with billions of dollars of equipment, armaments and ammunition—including 40 mm high-explo- sive grenade cartridges—to combat Russian forces as their illegal invasion rages on. As modernization remains a top priority for the Army, leaders


directed to replenish U.S. ammunition stockpiles with newer, modernized rounds that add capability, rather than “new, old rounds” that use antiquated and older technology.


Te Joint Program Executive Office for Armaments and Ammunition (JPEO A&A) Project Manager Maneuver Ammunition Systems (PM MAS) medium caliber team on Picatinny Arsenal, New Jersey, is seizing the opportunity to accelerate the development of new and more lethal cartridges—like the 40 mm low-velocity M433E1 high-explosive, dual-purpose (HEDP) cartridge for the M320 grenade launcher—to provide overmatch ammunition to the warfighter in the near term. Te HEDP warhead combines pene- tration ability with a fragmentation effect that lethally reaches a wider area of targets.


To date, the Army has provided Ukraine a combined 77 million rounds of ammu- nition. Tat equates to more than $210 million, and includes more than 1 million 40 mm rounds consisting of both the higher penetrating, high-velocity M430A1 HEDP, fired from the MK19 grenade machine gun, and the low-velocity M433 HEDP, fired from M320 and M203 grenade launchers, to accompany the weapons platforms the U.S. supplied Ukraine.
