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 Safety Release for First Unit Issued (FUI) of ERCA to perform 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 2024 funding will continue to support efforts to improve propellant for longer cannon life, conduct risk reduction activities, as well as FMR Supercharge component development and testing. FY 2024 funding will also support the initiation of Extended Range Cannon Artillery System of Systems (ERCA SoS) integration activities. These efforts directly support the Army's Long Range Precision Fires Cross Functional Team (LRPF CFT) priorities in support of the National Defense Strategy.
