Precision Guidance Kit
Abstract
The Long Range-Precision Guidance Kit (LR-PGK) XM1171/XM1172 development effort will qualify state of the art technologies for a course correcting fuze that provides precision accuracy at extended ranges for current and future 155 millimeter (mm) High Explosive (HE) projectiles by eliminating a portion of the inherent errors associated with ballistic firing solutions, which effectively reduces the number of projectiles required to execute fire missions. LR-PGK will support projectile operation in Global Positioning System (GPS) degraded environments and compatibility with Army Modernization objectives under the Long Range Precision Fires Cross Functional Team's (LRPF CFT) new long range cannon, Extended Range Cannon Artillery (ERCA) Self-Propelled Howitzer (SPH). The ERCA and its new long range projectiles require the LR-PGK to meet lethality requirements. Fiscal Year (FY) 2022 funding supports the fabrication of LR-PGK qualification test hardware and completion of guided flight testing with the XM1113ER projectile, XM655E1 Supercharge propellant and the ERCA weapon platform and accomplishes a system Critical Design Review (CDR) in support of Safety Release for First Unit Issued (FUI) for the ERCA Increased Range Operational Assessment.
