Device provides pulses of electrical energy through streams of high pressured electrolytic fluid to disable electrical components within a vehicle

The U.S. Navy seeks to commercialize U.S. Patent 6,723,225 (Automobile engine disabling device).   


It is estimated that over 7,737 police pursuits occur each year throughout the United States; with approximately 1,123 (25%) ending in crashes, and 694 (9%) of these crashes leading to injuries/death to either an officer, bystander, or suspect. These statistics have fueled the debate on whether high speed pursuits should be restricted or banned altogether.* Current methods employed by law enforcement to immobilize fleeing vehicles consist of road blocks, cargo nets, road spikes, and evasive PIT (precision intervention tactic) maneuvers. While these methods can be effective, they can be easily avoided by a pursued vehicle and may cause damage to unsuspecting persons and/or property.

The Technology

SSC Pacific has developed a technology that allows a user to disable a vehicle from a safe distance during high-speed pursuits. The device is composed of a fluid delivery system coupled to an electrical power source, which propels streams of conductive liquid onto a target vehicle. The streams act as tethers creating a closed circuit for pulses of electrical energy to be delivered, disrupting and disabling the vehicle’s electrical systems. The device can be outfitted to various mobile and aerial platforms.
