NEW CAPABILITIES AND CONCEPTS
cartridges being used for qualification on production-represen- tative equipment. Tis analysis will ensure the cartridges being qualified are the most representative of cartridges that would be produced and fielded.
Qualification testing of M433E1 cartridges began in January. Te cartridges will be evaluated against requirements developed by the Maneuver Center of Excellence at Fort Benning, Geor- gia, and upon successful qualification, PM MAS will procure the new M433E1. Te first lots of M433E1 cartridges are expected to be delivered into inventory and available for the warfighter at the end of the 2024 fiscal year, with full materiel release planned for fiscal year 2025.
CONCLUSION JPEO A&A PM MAS is eager to replace legacy cartridges and field the new, modernized 40 mm low-velocity M433E1 HEDP cartridge to the warfighter and to Ukraine. Te M433E1 gives the warfighter a new low-velocity 40 mm tactical cartridge that’s safer, more accurate and more lethal than the legacy cartridge when fired out of both the M320 and M203 grenade launchers.
As the war between Ukraine and Russia continues, JPEO A&A will continue to look for additional opportunities to replenish inventory with new, modernized cartridges to ensure the Army has the most lethal armaments and ammunition in the world.
