Precision Guidance Kit
Abstract
The Precision Guidance Kit (PGK) M1156 is a course correcting fuze that provides precision accuracy and efficiency 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. PGK utilizes a Global Positioning System (GPS) receiver and internal Guidance and Navigation Computer to accomplish its mission with point detonating and height of burst fuzing functions. The PGK M1156E1 development effort, Long Range-PGK (LR-PGK), will qualify state of the art technologies for operation in 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). The ERCA and its new long range projectiles require the LR-PGK to meet lethality requirements, and will be fielded during the PGK Life Cycle. LR-PGK supports the Army's modernization priorities in support of the National Defense Strategy and future 155mm projectiles and M777 Long Range Cannon (LRC) initiatives. Fiscal Year (FY) 2021 funding supports the award of a follow-on Engineering and Manufacturing Development (EMD) contract for system design and prototype development for LR-PGK.
