V2X Inc. has partnered with Horstman Group, part of RENK, to provide next-generation suspension systems for the US Marine Corps’ Amphibious Combat Vehicle fleet. The agreement centers on Horstman’s Hydrostrut hydro-pneumatic suspension, a technology designed to improve stability, mobility, and crew comfort during amphibious and cross-country operations.
Hydrostrut combines pressurized nitrogen gas with an integrated oil damper into a single compact assembly, optimizing space within the vehicle while delivering enhanced ride control. The system is scalable and compatible with multiple vehicle configurations, including 4×4, 6×6, and 8×8 platforms, supporting both tracked and wheeled armored vehicles.
The partnership follows extensive US military testing and validation of the Hydrostrut system. It comes less than 15 months after the first batch of suspension units was delivered for the ACV program, with additional shipments scheduled to start later this year and continue through 2026. The effort supports sustained production and incremental upgrades to the Marine Corps’ amphibious vehicle fleet.
The Amphibious Combat Vehicle is a core element of the Marine Corps’ plan to modernize ship-to-shore assault capabilities. Designed to replace legacy AAVs, the ACV has been developed into multiple mission variants since 2018. A standard configuration includes a remote weapon station, seating for 13 passengers, a three-person crew, and a payload exceeding three tons. Powered by a 700-horsepower diesel engine, the vehicle can reach 65 mph on roads, operate at 7 mph in water, and has a range of approximately 250 miles, offering flexibility across expeditionary missions.
