The Ripsaw is a developmental Unmanned Ground Combat Vehicle designed and built by Howe & Howe Technologies for evaluation by the United States Army. The Howe brothers started the Ripsaw as a small family project in 2000. They introduced it at a Dallas vehicle show in 2001, where it caught the interest of the U.S. Army. Later that year the U.S. Military ordered a prototype MS-1 to be made and shipped to Iraq. The Ripsaw is intended to perform various missions including convoy protection, perimeter defense, surveillance, rescue, border patrol, crowd control, and explosive ordnance disposal. For perimeter defense or crowd control, a belt of M5 Modular Crowd Control Munitions can be mounted around the vehicle to break up crowds or non-lethally engage personnel with flash-bang effects and rubber bullets. Cameras provide 360-degree coverage for situational awareness for the operator. The Army has tested the Ripsaw while remote-controlled by a soldier in another armored vehicle up to away. Its weapon system is modified to fire remotely using the Advanced Remote Armament System, a gun that loads its own ammunition and can swap out various types of ammunition, such as lethal and non-lethal, in just a few seconds. These capabilities allow manned vehicles to send the Ripsaw out in front of them and engage targets without exposing soldiers to threats. As of March 2017, the Army is still testing the vehicle as an unmanned platform to test remote weapons stations.
Variants
Ripsaw UGV prototype could accelerate to in about 3.5 seconds, since it was lighter, but it wasn't as strong/rugged.
Ripsaw MS1 tactical UGV utilizes a powerful oversized and customized Duramax 6.6L V8 diesel engine that delivers of torque. The Ripsaw MS1 was a test platform made to test off-road capabilities. It was exclusively unmanned, cost $200,000 and could accelerate from in 3 seconds.
Ripsaw MS2 UGV is made to be larger, faster, and more modular than the MS1. It weighs and can carry a payload. The lightweight tubular chassis design is powered by a 6.6 liter duramax diesel engine generating and of torque. Fully loaded, the MS2 can accelerate from in 5.5 seconds and has a top speed of. The vehicle can traverse 50 degree gradients and 45 degree slopes. It can be optionally manned or tele-operated from a nearby command vehicle. Armament can include an M240 machine gun or M2.50-caliber machine gun, and it has been tested with the Javelin missile. If the Ripsaw is damaged or destroyed, parts can be "cannibalized" in the field and re-assembled quickly. An MS2 vehicle costs $750,000.
Ripsaw EV2 is a luxury version, with a fully enclosed body and two seats inside the cab. It can exceed speeds of over and has a range of approximately. It is currently unknown if the EV2 can mount remotely-operated weapon systems or not. This model is designed for the civilian market but still costs $295,000 with customizable features.
