The updated SIL features a Ground Vehicle Operating System (GVOS)-based architecture with a Tactical Assault Kit Extended (TAK-X) framework to simplify integration of new capabilities. A demonstration of the system was also conducted for U.S. Government attendees, showcasing the enhanced electronics of the Cottonmouth ARV.
Textron Systems had previously performed a live demonstration during the critical design review (CDR) in October 2024, highlighting the upgraded systems in a simulated environment. A prototype of the ARV equipped with a 30mm weapon system is also scheduled for delivery to the Marine Corps in 2025 for further testing and evaluation.
The purpose-built Cottonmouth ARV has been developed to improve the Marine Corps’ ability to conduct reconnaissance missions with enhanced mobility, survivability and modular mission packages. Its MOSA-based design enables seamless integration of both government- and contractor-supplied capabilities, allowing for future upgrades to meet evolving requirements.
“The ARV’s advanced mobility, MOSA design and enhanced reconnaissance capability will be revolutionary for the MRBs,” said David Phillips, Senior Vice President, Air, Land and Sea Systems. “The upgraded SIL is another key component in supporting the USMC’s ARV mission, and we look forward to getting it in the hands of ARV operators to train and simulate real-world environments.”
Textron Systems has a long history of vehicle production at its Slidell, Louisiana facility, where it has manufactured thousands of ground vehicles over the decades. The Cottonmouth vehicle, developed from a clean-sheet design, is a 6×6 wheeled amphibious reconnaissance platform tailored for use in the Marine Corps’ Expeditionary Advanced Base Operations (EABO) concept.
