L-3 Klein Delivers HarborGuard Systems

SALEM, N.H., May 5, 2011 – L-3 Klein Associates, Inc. (L-3 Klein) announced today the first deliveries of its HarborGuard Integrated Waterside Security and Surveillance System for a major U.S. security upgrade program. With its ability to provide immediate alerts and updated threat positions, L-3’s HarborGuard System is a key component of new security measures throughout the U.S. that provide continuous coverage and monitoring of all surface activity around dams, with special attention on security zones to protect critical infrastructure.

HarborGuard solves the unique challenges of providing security to dams that have dramatic changes in water levels. Unlike traditional radar systems that need constant mechanical and electrical adjustments to compensate for any water level changes, HarborGuard features specialized products and software that allows it to easily accommodate changing water levels.

“L-3 Klein’s HarborGuard System is used at a number of critical U.S. infrastructure facilities that require the highest level of continuous surveillance,” said John Cotumaccio, president and general manager of L-3 Klein. “We have a strong footprint in the industry and have gained recognition for providing one of the most cost-effective waterside security systems designed and manufactured in the USA.”
