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 XM1299 Increased Range (formerly Increment 1C) and XM1299A1 Increased Rate of Fire (formerly Increment 2) Extended Range Cannon Artillery (ERCA) Self-Propelled Howitzer (SPH). It 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 (foamed celluloid or felted fiber technology), integral metal Stub Case, electrically initiated primer, and advanced artillery propellant. Fiscal Year (FY) 2022 funding will support efforts for aforementioned two parallel Supercharge variants (bag and cased) to support the concurrent development of ERCA Increased Range (IR) and ERCA Increased Rate of Fire (IRF) with automated loading system. This project supports Bag Supercharge qualification required for FY 2023 Safety Release for First Unit Issued (FUI) of XM1299 ERCA Increased Range to perform Operational Assessment. This project also supports concurrent engineering, manufacturing development of the Cased Supercharge for future fielding with ERCA IRF. These efforts directly support the Army's Long Range Precision Fires Cross Functional Team (LRPF CFT) priorities in support of the National Defense Strategy.
