The Proof Gun Stand (PGS) is an interoperability platform developed by the USG, initially fielded in 2023 with additional fielding planned for 2025. This system eliminates the need for existing weapon systems in testing, mitigating wear and tear. The PGS is ideal for ammunition evaluation (new, foreign, lot acceptance, interchangeability) and cannon evaluation (proofing, interior ballistics assessment, interoperability). It is a hard-mounted platform with a wide operational range (-2.5° to 72° elevation, 360° traverse), engineered for a 30-year service life in harsh environments, and adaptable to various ground conditions. Its modular gun mount accepts 105mm to 155mm cannons using a “Tube Sleeve” system, with current configurations for M776 and M199 cannons. The PGS is designed for transportability, separating into three subsystems for easy installation and compliance with highway standards. Maintainability is also a focus, with contracts for sparing and ease of maintenance. Customer input for cannon integration includes Interface Control Drawings, Pressure Versus Time Curves, and Muzzle Brake performance. The USG will conduct engineering studies to evaluate requirements and develop cannon kits, which may include recoil dynamics evaluation, Tube Sleeve Adapters, and breech/priming hardware. The USG aims to standardize the PGS as the common interoperability platform for all ammunition and cannon validation, with plans to produce and support additional units due to its flexibility in test range applications.
