L-3 Communications’s Security and Detection Systems subsidiary has been selected by the Homeland Security Advanced Research Projects Agency (HSARPA) to provide 30 state-of-the-art prototype cargo container security devices for field testing. L-3 is one of two companies downselected from an original five to receive Phase II funding from HSARPA for the development of the cargo container security devices. The cost-share program uses government and corporate funding valued at over $5m. L-3's Advanced Container Security Device (ACSD) will continually track the sequence of a cargo container's journey from the moment it is sealed until it is released at its final destination.
