The basic vision of the enhanced border security plan is to construct a high-tech security system that integrates personnel, infrastructure, technologies, and rapid-response capability. The project sprang from legislation that approved the development of 370 miles of fence in areas most often used by smugglers, 500 miles of vehicle barriers, and “virtual” fencing using cameras, sensors, and other technology. Five major defense contractors are expected to bid on the project: Lockheed Martin Corp., Boeing Co., Northrop Grumman Corp., Raytheon Co., and Ericsson Inc. The plans of the defense contractors are briefly described, all of which rely on integrating proven technologies such as infrared cameras, radars, and sensors with the traditional manpower of the Border Patrol agents. For example, Boeing plans to use stationary and mobile towers in addition to unattended ground sensors, radar, infrared cameras, and small, unmanned aircraft to patrol the border. Raytheon Co. plans to use sensors and cameras that will be deployed on various platforms such as unmanned aerial vehicles, airborne vehicles, and tethered aerostats. The DHS expects to name the winner of the SBI-Net contract by September 30, 2006; the contract is expected to run for 3 to 5 years and could ultimately be valued at $8 billion if the U.S. moves to secure maritime borders as well. The article includes a textbox offering brief statistical information about border security as well as the team members of the five defense contractors expected to bid on DHS’s border security project.
