155mm Artillery Propulsion XM654
Abstract
155MM Artillery Propulsion Supercharge funding will support the Army's Cannon Modernization Strategy, which includes Paladin Integrated Management (PIM) Armament Upgrade and Next Generation Cannon, and all utilized cannons that are 52-calibers or longer; such as the future 58-caliber Extended Range Cannon Artillery (ERCA). Supercharge is a stand-alone top-zone 155 millimeter (mm) propelling charge required to achieve maximum range requirements beyond 50 kilometers (km) from Self-Propelled Howitzer (SPH) equipped with cannon length greater than 52-calibers. Supercharge will achieve lethality overmatch out to 70km from future US-developed and produced Long Range Precision Fires Weapon Systems using both existing and developmental extended range projectiles and will potentially increase range with compatible legacy projectiles up to thirty percent. Supercharge is composed of an earlier bag variant and later combustible cartridge case, integral metal stub case, electrically initiated primer, and advanced artillery propellant. This Project supports the Urgent Materiel Release (UMR) Supercharge (bag configuration) qualification required for fielding an initial capability of two battalions, and also supports the development of the Full Materiel Release (FMR) Supercharge that will address high technology and integration risks unique to achieving extended range to include improved design opportunities for pressure temperature curve, cannon tube wear and ensure fielding robustness. FY 2025 funding will continue to support Supercharge component development, improve propellant for longer cannon life, conduct testing and development of artillery propulsion charges and primers in support of the Army's Cannon Modernization Strategy.
