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 XM1299A1 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 increase range with legacy projectiles by thirty percent. Supercharge is composed of combustible cartridge case (foamed celluloid or felted fiber technology), integral metal Stub Case, electrically initiated primer, and advanced artillery propellant. Fiscal Year (FY) 2021 funding will support design risk reduction and prototype maturation efforts for two parallel Supercharge variants (2-piece bag and cased) to support the concurrent development of ERCA Increment 1C and ERCA Increment 2 (with added automated loading system), which directly supports the Army's Long Range Precision Fires Cross Functional Team priority in support of the National Defense Strategy.
