155mm Artillery Propulsion XM654
Abstract
Supercharge is a stand-alone top-zone 155 millimeter (mm) propelling charge required to achieve maximum range requirements from the Extended Range Cannon Artillery (ERCA) Self-Propelled Howitzer (SPH). Supercharge will achieve lethality overmatch out to 70 kilometers (km) with 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 accelerated Urgent Materiel Release (UMR) Supercharge (bag configuration) qualification required for FY 2023 Safety Release for First Unit Issued (FUI) of ERCA to perform FY 2024 Operational Assessment, 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 2023 funding will conclude safety qualification of the UMR Supercharge, improve propellant for longer cannon life, conduct risk reduction activities and continue component development and testing of the FMR Supercharge. These efforts directly support the Army's Long Range Precision Fires Cross Functional Team (LRPF CFT) priorities in support of the National Defense Strategy.
