U.S. Army soldiers finally get a modern lethal hand grenade after 58 years, ditching the asbestos-riddled relic from the Vietnam era to bolster combat readiness under President Trump’s defense priorities.
Breaking the 58-Year Drought
The U.S. Army granted Full Material Release to the M111 Offensive Hand Grenade on March 10, 2026. This approval enables full production and fielding across forces. Developed at Picatinny Arsenal by DEVCOM Armaments Center and CPE A&E, the M111 marks the first new lethal hand grenade since 1968. It addresses long-standing gaps in close-quarters capabilities exposed in modern conflicts. President Trump’s focus on military strength accelerates such vital upgrades, prioritizing American troops over outdated gear.
Overcoming Vietnam-Era Limitations
Since 1968, soldiers relied on the M67 fragmentation grenade and the restricted Mk3A2 offensive grenade. The Mk3A2’s asbestos body posed health risks, limiting training and deployment. Urban fighting in Iraq from 2003 to 2011 revealed M67 dangers: fragments ricocheted off walls or penetrated barriers, endangering fellow troops. The M111’s blast overpressure design propagates through enclosed spaces without shrapnel, slashing fratricide risks. This tactical evolution equips soldiers for today’s battlefield realities.
Col. Vince Morris, Project Manager at CPE A&E, stated the M67 often proved unsuitable due to high fratricide potential in buildings. The M111 clears rooms effectively while protecting friendlies. Engineer Tiffany Cheng highlighted its flexibility, allowing troops to select the right grenade per scenario—fragmentation for open areas, overpressure for confined ones. Such innovations restore confidence in Army munitions after decades of stagnation.
Design Innovations for Soldier Safety
The M111 features a plastic body that fully consumes on detonation, eliminating asbestos hazards. It uses the same fuze and arming mechanism as the M67 and training M69 grenades. This standardization supports “train as you fight” doctrine and drives cost savings through economies of scale. No external contractors were involved; internal Army teams streamlined development. Full Material Release confirms rigorous safety and performance testing, paving the way for rapid deployment.

Modern warfare demands urban proficiency in buildings, tunnels, and bunkers. Blast overpressure outperforms fragments in these environments by traveling through obstacles. The M111 complements the M67, enabling mission-tailored loads. Short-term gains include safer training and replaced stockpiles; long-term benefits reduce casualties and adapt to peer adversaries. This upgrade boosts Picatinny Arsenal’s R&D leadership and may influence allied forces.
