At the "Modern Marine Corps Expo" held recently in Washington, D.C., Textron Systems officially demonstrated an unmanned combat platform specially designed for the U.S. Marine Corps - Ripsaw M1. This robotic combat vehicle is positioned as a "multiplier" for man-machine collaborative operations and will perform tasks in conjunction with the Marine Corps' new generation Advanced Reconnaissance Vehicle (ARV) and Amphibious Combat Vehicle (ACV).
According to the "Reshaping and Modernization" plan that the U.S. Marine Corps continues to advance, the military is gradually replacing the AAV7A1 amphibious assault vehicle and LAV-25 light armored vehicle that have been in service since the 1970s with ARVs and ACVs respectively. This upgrade is not only intended to improve platform performance and crew safety, but also emphasizes the use of modular and networked architecture to reserve interfaces and space for collaborative operations with unmanned ground vehicles such as Ripsaw M1.
Ripsaw M1 continues the technical pedigree of the previous Ripsaw series of robots, but is different from the large M5 developed for the US Army. The M1 vehicle is more compact and changes the traditional tracked structure to a wheeled design. The reason is that the Marine Corps attaches great importance to amphibious and littoral combat capabilities, and the M1 must be able to adapt to humid and complex terrain environments such as beachheads and coastal areas.
In terms of combat positioning, the Ripsaw M1 is regarded as the "teammate" and "combat power multiplier" of the ARV. The ARV serves as the command center, and the M1 serves as the forward reconnaissance force. The vehicle weighs approximately 4,300 pounds (approximately 1,950 kilograms), is approximately 10.5 feet (approximately 3.2 meters) long, and can carry a mission load of up to 2,000 pounds (approximately 907 kilograms). Its all-electric all-wheel drive system can reach a top speed of 53 miles per hour (about 85 kilometers per hour), can still maintain a speed of about 20 miles (about 32 kilometers per hour) in silent mode, has a range of up to 30 miles (about 48 kilometers), and has the ability to pass through water obstacles up to about 48 inches (about 123 centimeters) deep.
In stealth operating mode, M1 can rely on high-resolution sensors to perform reconnaissance missions and collect battlefield intelligence. It can also act as a "bait" in high-risk areas such as complex terrain and narrow passages, entering potential ambush areas before manned platforms, luring enemy firepower into exposed positions, or used to detect obstacles and clear pathways.
The Ripsaw M1 is more than just a "carrying mule" or reconnaissance platform, though. Its modular design allows it to be quickly modified into a variety of combat configurations, including a hard-kill anti-drone weapon platform, or equipped with a hovering munition system such as "Damocles" to search for and continue to wait in the air for targets to strike before they appear. By replacing the mission module, the M1 can flexibly switch between air defense, suppression, fire support and other roles according to different battlefield environments.
Sara Willett, vice president of programs at Textron Systems, said the M1 technology demonstration platform demonstrates the “highest possible limit” of what unmanned ground vehicles can support Marine Corps missions. The company and the Howe & Howe team have pooled their experience in multi-domain autonomous robotic systems on land, air, and sea into this platform. Based on a common "robot core", while maintaining a common architecture, the size, weight, and power of the platform can be scaled up or down based on mission requirements, thereby striking a balance between transportation mobility and battlefield agility.
