Ripsaw, Unmanned Light Tank By Howe & Howe Technologies

To date, multiple prototype variants of the Ripsaw exist:
• Ripsaw UGV (non-militarized) prototype could accelerate to 60 mph 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 650-horsepower Duramax 6.6L V8 diesel engine that delivers 900 ft-lbs (~ 1,220 Nm) of torque.
